The new CO2 tax: What does it mean for your company?

Since 01 January 2021,CO2 pricing, also known as the "CO2 price" or "CO2tax", has been in force. In the eyes of many entrepreneurs and consumers, this is an additional burden, as the new levy will cause energy prices to skyrocket, thereby increasing heating costs, among other things. Learn more about the newCO2 tax and its consequences in this article.

NowCO2 also has a price in Germany

To protect our livelihoods, the global community agreed at the 2015 UN Climate Change Conference in the Paris Agreement to limit global warming to well below 2°C, and preferably to 1.5°C. To achieve this, we must be greenhouse gas neutral from 2050. Since then, more and more measures have been developed to achieve this goal - both internationally and at the European and national levels. The European Union aims to reduce greenhouse gas emissions by at least 55 percent by 2030 (the year of comparison is 1990). With the so-called EU ETS (European Union Emissions Trading System), there is emissions trading for almost the entire energy industry. The goal: to reduce climate-damaging gases by issuing a limited number of emission rights as an incentive to do so and trading them freely on the market. Outside of European emissions trading, however, such an incentive has been lacking. In the National Climate Protection Program 2030, the German government therefore adopted price incentives in addition to subsidy programs and regulatory measures.

The transport and heating sectors are particularly important, as they account for around one-third of climate-damaging emissions. CO2 emissions in the heating segment alone are to be reduced by 80% by 2050. The way to this was paved when the Fuel Emissions Trading Act (SESTA) came into force at the end of 2019. Based on this, greenhouse gas emissions now also have a price in Germany. Since 2021, Germany has relied on its own additional instrument for reducingCO2 emissions, known as theCO2 tax, in the form of national emissions trading (nEHS). The federal government is thus setting clear goals:

  • Achieving the minimum targets of the EU climate protection regulation
  • Meet national climate protection targets, especially greenhouse gas neutrality by 2050.
  • Improve energy efficiency

How does theCO2 tax work?

The newCO2 tax, which has been in force since January 01, 2021, relates to the transport and building heat sectors. It stipulates that the combustion of fossil fuels such as heating oil, liquefied petroleum gas, natural gas, coal, gasoline and diesel will be "taxed" with immediate effect by a fixed, gradually increasing price. This is intended to create incentives to use less energy and switch to more environmentally friendly alternatives.

But how does theCO2 tax work now? Companies that place these fuels on the market must acquire so-called "emission rights" with certificates. These allowances are based on a predetermined threshold quantity of emissions; their number is reduced from year to year. Who acquires these certificates differs depending on the fuel. In the case of natural gas, for example, these are the municipal utilities as those who supply the end consumers. Certificates for petroleum products have to be purchased mainly by producers (e.g. refineries) and traders. The cost of these emission allowances will be passed on to end users, i.e. residential customers and businesses, with the result that prices for heating fuels and motor fuels will rise from 2021 onwards.

What additional costs will you incur with theCO2 tax?

To enable business and consumers to gradually adjust to the new system, fixed prices will initially apply to theCO2 tax. They will start at 25 euros per metric ton ofCO2 in 2021 and rise gradually until 2025. From 2026, the scheme envisages that the cost of theCO2 tax will initially develop in a price corridor between €55 (minimum) and €65 (maximum) per metric ton ofCO2, depending on the market, and will move to a free trading phase from 2027. In 2025, a decision will be made at the political level on further pricing. Thus, fossil fuel costs will increase gradually, most moderately for natural gas at 6 cents per 10 kWh in the first year.

What does theCO2 tax mean in concrete terms and what should you do?

First and foremost, theCO2 tax means two things:

  1. Heating and mobility are becoming more expensive.
  2. Energy sources, energy use and technologies must be reassessed and made much more efficient to absorb rising costs.

In line with the motto "The cleanest and cheapest energy is that which is not consumed in the first place," the German Federal Ministry for Economic Affairs and Energy is focusing on resource conservation with its Deutschland macht's effizient campaign, among other things. The principle of "efficiency before substitution" applies here. For example, if you are already currently using modern, decentralized efficiency technologies for heating that use fossil fuels but are very energy efficient, there is less need for action. By the way, from a height of more than four meters, you are exempt from the Renewable Energy Obligation of the GEG when heating with decentralized technologies in the new construction of hall buildings.

Energy efficiency is not only a necessity from an ecological point of view, but is also increasingly important from an economic point of view. Therefore, of course, in the long term you should not hesitate to modernize your heating system or switch to alternative energy sources. This can also be natural gas in the future - because: The upcoming feed-in of hydrogen (power-to-gas) and the possibility of producing natural gas synthetically will make this energy source increasingly greener and more renewable. For more information, read our article on future technologies for heating modernization!

What opportunities does business have to save costs despite theCO2 tax?

The good thing about the SESTA and the newCO2 tax is that policymakers are using them to create real incentives to make companies and consumers more energy efficient, to use climate-friendly energy sources and to develop innovative products. Moreover, with the price regulation set until 2026, there is planning certainty and a sufficiently large window of opportunity to react. So as a company or consumer, you decide for yourself: Does it make more sense for you to pay theCO2 tax or to counteract the cost increase with suitable measures? Our tip: try to achieve your goals with as little energy as possible and examine the use of regenerative energies in the long term. This way, both sides benefit: the climate and your company. Below we give you examples of how you can increase energy efficiency:

  • Increased thermal insulation
  • The use of energy-efficient technologies
  • The use of heat recovery and residual heat
  • The use of intelligent control technology
  • Switching to energy sources with lower emission values (e.g., natural gas instead of fuel oil).
  • The integration of solar thermal and other renewable energies

How can rising costs be avoided?

  • § Section 11 of the SESTA ensures financial compensation to companies by way of a hardship clause if they are unreasonably affected by rising prices. Prerequisites are:
  • Fuel costs account for more than 20% of the total cost of operation.
  • Additional costs incurred by the company as a result of the introduction of the SESTA would exceed 20% of gross value added.

In addition, double burdens resulting from the use of fuels in a plant subject to EU emissions trading are to be avoided as far as possible.

It is also planned to provide relief to those companies that would experience disadvantages on the international market as a result of theCO2 tax. For many foreign competitors,CO2 pricing and the resulting increase in fuel costs are no longer an issue. The solution comes in the form of the so-called "Carbon Leakage Regulation": Those who suffer disadvantages on the international market as a result of theCO2 tax will receive financial compensation. This is how Germany wants to prevent companies from relocating. However, affected companies must demonstrate that they have an energy management system in place and are already working to reduce theirCO2 emissions. They must then use the benefits to further reduce theirCO2 emissions.

Will my climate protection measures be funded?

At the national level, the federal government supports investment in climate protection through a number of comprehensive, and in some cases updated, funding programs and grants. These include, for example, the Federal Support for Efficient Buildings (BEG) or the Federal Support for Energy Efficiency in Business. You can apply for these programs either as a grant through BAFA or as a loan subsidy through KfW. In addition, costs incurred for energy consulting are also subsidized.

What options can companies use if the investment costs are too high?

Anyone who cannot or does not want to invest, but still wants to use modern efficiency technologies to heat production halls and warehouses and thus reduce the additional costs caused by theCO2 tax, is well advised to use HeizWerk. This rental model is doubly interesting from an economic point of view - firstly, because companies incur neither investment nor depreciation expenses. Second, because the energy cost savings from efficiency technologies in energy retrofits of existing facilities are usually significantly higher than the rental amount. With the positive result that the companies even have extra money in their coffers after the modernization.

Conclusion: Start reducing your company'sCO2 emissions!

Even if theCO2 tax makes prices rise only slowly, you should not wait too long. Get an overview of your savings potential and reduceCO2 emissions and energy consumption in a targeted manner. Particularly in hall buildings, heating modernization promises great savings potential.

How to find the optimal hall heating

Do you want to get the most out of your new hall heating system, save energy costs and be prepared for environmental legislation of the future? Then it is advisable to consider some tips before buying. You can find out which ones in this article.

First of all, be aware that industrial and commercial buildings have different heating requirements than homes or offices. Sounds trivial? But it is not. Because, in fact, many planners still make the mistake of applying a heating strategy similar to that used for multi-story buildings. The problem: Warm air rises to the top. This is not relevant for low ceiling heights, such as in offices or apartments. In halls, on the other hand, the warm air collects quasi uselessly at a great height under the hall roof.

Until it is pleasantly warm on the ground, operators have to channel a lot of heating energy into the hall and use systems that direct air flows back down. Basically a waste of money, because heat is usually only required in large halls at a person height of around two meters, but not at higher elevations. Therefore, as a rule, it is enough to heat 20 percent of the volume of the room. Already then employees have it pleasantly warm and can develop full productivity.

Find the right technology for your hall heating

Now the question is what technology to consider to specifically heat the 20 percent or so of your hall. If you look around the market, you will notice: There are centralized and decentralized heating systems. Central systems include such things as industrial radiant floor heating, centrally supplied water-based air heaters, and hot water radiant ceiling panels. They work with a central power generator and a piping system that transports hot water to the desired location.

On the other hand, decentralized heating systems include infrared heaters that can be mounted under the ceiling. They are gas-powered and work with electromagnetic waves. As soon as the waves hit a solid body, such as a person or the room frame, the energy is converted into heat. The highlight: Infrared radiators do not heat the air! In this way, only the occupied and usage area is heated.

At the same time, hall operators enjoy flexibility. They specifically divide the hall into different heating zones with several infrared radiators - and provide more heat to employees in order picking, for example, than to colleagues in production, where machines already provide sufficient basic heat. A flexibility that strengthens employee satisfaction. Even if the hall is converted, it is easier to adapt the system with these decentralized solutions compared to the centralized system.

Another advantage of infrared technology: it is responsive. Operators switch the heating on and off in a similar way to the lights. Since the energy does not take a detour via the air, heat is available virtually at the push of a button. And you don't even need to manually turn on and off in the automation age. This task is performed by intelligent control technology, which adapts the heating power to the changing conditions. Users thus reduce energy costs by up to 70 percent, so that the investment in the heating system pays for itself in a short time.

Get an overview of the requirements of your hall

In order for hall heaters to develop their full potential, they should be adapted to your hall like a tailor-made suit. However, this adaptation by an external service provider will only succeed if you have a clear picture of your hall building, hall use and your heating requirements in advance. Be particularly oriented to the factors that could have an impact on the temperature. These questions can help you do that:

  • What are the dimensions of your hall?
  • What is the condition of the building?
  • How is the hall used?
  • Are there different areas and times of use?
  • What about gate opening hours?
  • How has heating been done so far - is there consumption data?
  • What goals and requirements should the new heating system meet?

The answers to these questions provide a foundation on which your heating partner can build.

Think through different energy sources for your hall heating system

In times of climate change, the German government's targets are ambitious: Germany is to be climate-neutral by 2045 at the latest. Accordingly, industry is making efforts to reduce CO2 emissions. Many companies are saying goodbye to heating oil, which will be banned for new buildings from 2026 anyway, and are instead focusing on renewable energies and technologies such as solar thermal energy or electric heat pumps.

If you decide to go this route, however, you should be aware that you are committing to a central heating system. And for this you need a hydraulic distribution system. In addition, such a system is often associated with two to four times higher investment costs and is comparatively inert, so that in many cases the heat supply cannot be adapted quickly enough to dynamic requirements.

Infrared radiators work with natural gas. But compared to other fossil fuels, this gas is environmentally friendly as thelowest CO2 among the classic fuels, as it has the lowest primary energy factor of all. In addition, natural gas is becoming increasingly green due to the upcoming feed-in of regeneratively produced hydrogen (power-to-gas technology) and is considered one of the most sustainable energy sources in Germany, especially in conjunction with the excellently developed gas network.

Now you may be wondering: The new Building Energy Act (GEG) stipulates that in the future I may only heat with renewable energies. Isn't an infrared heater prohibited there? No! According to the GEG, from a hall height of more than four meters you are no longer bound to regenerative energy sources. While central heating systems are required to use renewable energy to meet GEG specifications, the most efficient infrared indoor heating technology allows them to be implemented using natural gas. So you don't have to worry about compliance.

Take a close look at hall heating suppliers

To ensure that you find an efficient and future-proof hall heating system, you should check the competence of suppliers in advance. The following questions are suitable for orientation:

  • What references does the provider have?
  • Is there a nationwide service (if you have or want to set up multiple locations).
  • Can you trust that you will still receive spare parts and service in 15 years?
  • Does the provider have a development department that is innovative and develops products according to modern standards?
  • Do the employees appear competent?
  • Is the system flexible? Can it be adapted to changes in the law and conversions without much trouble?

It is also advisable to focus not only on the price of the hall heating system, but also on the total cost of ownership (TCO) - i.e. the operating costs over the entire life cycle. Only with this value can you calculate whether it is a worthwhile investment.

4 good reasons to invest in an energy-saving and environmentally friendly hall heating system

Climate neutrality and energy efficiency are topics you can't get around these days. At the latest since the presentation of the coalition agreement of our new traffic light government, it has been clear that everything is to be done to stop climate change in the coming decades. As in the private sector, industry must also do its part to protect the climate and combat global warming. An important point is the investment in an environmentally friendly heating system, so that energy efficiency in the company is also required Read in this article, which reasons specifically speak for investing in a new heating system and strive for high energy efficiency in your company.

The pillars of the energy transition and how high energy efficiency in your company supports it

The energy turnaround plays a central role in industry and politics - high energy efficiency in companies as well as in the private sector is targeted. To achieve this, the name of the game is: Away from fossil fuels and toward renewable energies and greater efficiency. The motto with which the energy supply is to be transformed in the coming decades is thus clear. The energy transition is based on the following pillars:

  1. Expansion of renewable energies
  2. Increase energy efficiency in electricity, heating and cooling supply
  3. Increased energy saving

They play a decisive role in determining how hall operators should plan their heating systems in the future: Energy-saving and environmentally friendly, in order to achieve the highest possible energy efficiency in their company. This applies to both new buildings and refurbishment projects. Looking at these pillars, four reasons can be derived from them why you should move towards high energy efficiency in your company as early as possible.

1. numerous subsidies promote energy refurbishment

Particularly when modernizing the energy efficiency of your hall buildings, you can take advantage of numerous support programs and subsidies that pave the way to high energy efficiency in your company. For example, up to 80% of the cost of consulting services provided by an energy advisor is covered. This shows you where there is potential for savings in your company. Whether the measures are technical or structural is the same. This is because the overall energy balance of the building is considered as the basis for assessment. Federal funding opportunities include the Federal Efficient Buildings Grant (BEG) or the Federal Business Energy Efficiency Grant.

2. with high energy efficiency in your company, you pay less CO2-taxes

In order to give consumers an incentive to rely more on renewable energy sources, the CO2 pricing or CO2 tax came into force on 01 January 2021. Starting in 2021, this means that the prices of fossil fuels such as heating oil, liquid and natural gas, coal, gasoline and diesel will rise every year. This is because manufacturers or distributors now have to purchase emission rights, the cost of which they pass on to consumers. This means that anyone who operates their heating system with fossil fuels and does not optimize energy consumption in the process must expect costs to rise. This in turn means that anyone who focuses on high energy efficiency in his or her company will benefit. Efficient, environmentally friendly heating systems that consume little energy and, if possible, are powered by gas, the lowest-carbon fossil fuel, and can be increasingly powered by regenerative sources in the future are the ideal alternative to outdated heating systems here. This way you save heating costs and contribute to climate protection at the same time.

3. energy efficiency in the company is a central component of the energy transition

The Energy Efficiency Strategy 2050 of the German Federal Ministry for Economic Affairs and Energy sets clear targets: By 2030, primary energy consumption in Germany is to be reduced by 65 percent compared with 1990. A reduction target of at least 88 percent applies by 2040. Germany is to achieve greenhouse gas neutrality by 2045. The measures for this are bundled in the National Action Plan on Energy Efficiency (NAPE 2.0). "The cleanest and cheapest energy is that which is not consumed in the first place," is the motto of the energy efficiency strategy. To achieve these goals, Germany wants to drive energy efficiency in companies, especially in the building sector, establish energy efficiency as a return on investment and business model, and increase ownership of energy efficiency.

In summary, this means for you as a hall operator: In the future, you will no longer be able to avoid energy efficiency in your company. Over their entire life cycle, hall heating systems consume around six to twenty times more energy than the investment costs. In view of the total cost of ownership, the rising prices for fossil fuels, and the growing demands on your company's energy efficiency, it therefore makes little economic sense to invest in conventional heating systems. Therefore, when constructing or renovating your hall buildings, plan for the long term so that you do not have to replace your heating system again in just a few years.

Modern hall heating systems are convincing due to their efficient operation, with which the investment costs are amortized in a very short time. They are therefore worthwhile not only from an energy policy perspective, but also in terms of total cost of ownership. For example, a modern gas-powered infrared heater works so efficiently that you can save up to 70% energy. In addition, industrial heating systems have long been able to be networked with other technologies to maximize energy efficiency for your company: residual heat is used to generate hot water, for example, which can then be used to heat adjacent offices, among other things. Waste heat from production processes can be integrated into the systems, as can energy from solar thermal systems. And one thing is clear: the less energy you let go to waste, the more environmentally friendly your company is.

4. energy efficiency in the company with some self-determination - how the GEG gives you leeway in planning your heating system.

Owners of newly constructed buildings are obliged to use regenerative energies - but in the area of hall buildings, the situation is quite different. This may come as a surprise, because since the EnEV and EEWärmeG were passed in a rush over 10 years ago, the rumor has persisted that there is no way around renewable energies in non-residential buildings either - even though in many cases they were not the most efficient choice.

This supposed requirement is still anchored in the minds of many planners, because the second pillar of the energy turnaround - namely energy efficiency in companies and private buildings - was disregarded by the legislator at the time. The same applies to the fact that hall buildings have completely different physical and heating requirements than multi-story buildings. However, this was gradually remedied with the amendments to the EnEV and EEWärmeG. And most recently in November 2020, when the new Building Energy Act comes into force: the GEG puts the focus on the principle of "efficiency instead of substitution". From a hall height of 4 m, you do not have to use regenerative energies when operating decentralized heating systems, which in most cases actually leads to higher energy efficiency in your company.

Therefore, when planning your heating system, you have numerous options to make it both environmentally friendly and efficient. And you can do this even with natural gas, a low-carbon fossil fuel, as long as your industrial heating system operates efficiently. This is because this fuel has a good primary energy factor, is increasingly green due to the coming synthesization, and is considered a bridging technology on the way to a climate-neutral future.

Conclusion: There is much to be said for high energy efficiency in the company through environmentally friendly hall heating systems

Especially the energy and cost savings speak for themselves when you think about investing in a modern heating system. In addition, legislation is increasingly urging companies to use environmentally friendly technologies to achieve a high level of energy efficiency in the interests of climate protection. This is additionally supported by numerous funding programs. Therefore, there are no more excuses for an energetic renovation or an environmentally friendly new planning - so don't wait any longer and go for the highest possible energy efficiency in your company. Tackle the project - KÜBLER will be happy to support you.

Infrared hall heating in your production: how to create the right indoor climate at work

Infrared hall heating in your production: how to create the right indoor climate at work 

Hall buildings are a world unto themselves. Especially in winter, their high ceilings pose a real challenge for anyone who wants to ensure the most pleasant possible working environment in the workplace. But there are solutions - for example, infrared hall heating. But first you should ask yourself: what does comfortable indoor climate mean anyway? And what factors are decisive for this? There are various representations of this, which basically boil down to four different factors, which we will introduce to you in this guide. 

4 factors that influence a pleasant indoor climate at work 

Basically, when it comes to a comfortable indoor environment at work, you should always pay attention to these four factors: 

  • Temperature 
  • Humidity 
  • Air movement 
  • Air quality 

While the temperature depends to a large extent on the type of activity (18 °C sensation temperature is sufficient for physical work, at least 20 °C is necessary for sitting), there is agreement on the factors of humidity, movement and quality of air. 40 - 60 % humidity, an air movement of no more than 0.15 m/s (at 21 °C) and an oxygen content of 21 % are standard values that most people find pleasant and thus constitute the optimum room climate at the workplace. 

The right indoor climate in the workplace influences the productivity of your employees 

It is a proven fact that a poor indoor climate in the workplace has a negative impact on the willingness and ability of your employees to perform. You notice it at the latest when complaints come in or sick leave increases. Among many other bodies, the German Federal Institute for Occupational Safety and Health (baua) has looked into this and writes about it in a report published in 2016: 

"Small deviations from the "climate optimum" initially lead to disturbances of well-being, complaints about the climate (too warm, too cold, there is a draft) are the result. If these effects are amplified and climate monotony or the inability to influence the climate itself is added, this can lead to a high level of dissatisfaction, stress and psychological strain; motivation and satisfaction with one's own work decline. Ultimately, the willingness to exert effort decreases, employees feel less capable, and objectively measurable productivity losses and increased error rates can occur."  

The problems you face when you want to create the optimal indoor climate in the workplace 

Hall buildings are not easy to heat. Due to the fact that the premises are particularly large and high, it can also be particularly challenging to achieve the ideal indoor climate in the workplace. What problems arise when choosing a hall heating, you will learn below. 

Problem 1: The size of hall buildings as the biggest challenge for the indoor climate in the workplace 

In offices, it is still relatively easy to positively influence the indoor climate. If, on the other hand, the workplace is a production hall, those responsible face completely different challenges. Because the company's goal of a "good working atmosphere" is facing headwind from various directions: 

  • Large ceiling heights from 4 to 20 meters and more
  • Long gate opening hours 
  • Different work areas and hall zones 
  • Different building floor plans and layouts 
  • Dynamic temperature requirements 
  • Insufficient insulation, esp. old halls 
  • High pressure to reduce operating costs 

So creating the optimal indoor climate at the workplace is anything but easy in a production hall. Just keeping the temperature in such a building at a comfortable level is not trivial. Especially because good and uniform heating must also be considered against the background of energy efficiency. Not to mention humidity, air movement and air quality. 

Problem 2: Not every heater contributes to a good indoor climate at the workplace 

A wide variety of technologies are used for hall heating. Not always with the desired result in terms of functionality, thermal comfort and economy. They differ according to the type of energy source (fuel oil, gas, wood, electricity, solar) and the type of supply: centralized or decentralized. Decentralized heated systems are the technology of choice in many applications today. In particular, gas-fired infrared hall heaters of the dark radiator type take a prominent role, because they are specially tailored for heating high spaces, where they offer important advantages. 

No hot air: Why infrared hall heaters are so good for the indoor climate in the workplace 

Infrared hall heaters are radiant heaters. These heating systems transfer heat by emitting infrared radiation. As soon as the rays hit bodies or objects, they are converted into heat. Thus, the effect of infrared hall heaters is similar to the heat principle of the sun, which heats not the air, but directly people, room frame, machines and other objects in the hall, resulting in a particularly pleasant indoor climate at work.

Radiant heating systems also have a decisive advantage in high rooms: where no air is heated, no warm air can rise high under the hall roof and form unused warm air cushions there - outside the working area. Infrared hall heaters are specially made to bring heat evenly to the area of use. And nowhere else. Incidentally, this is also the decisive reason why these systems are so energy-saving and thus so economical and environmentally friendly. 

Infrared hall heaters influence an optimal indoor climate at the workplace in many different aspects 

The uniform targeted temperature control is not the only reason why infrared hall heaters provide a pleasant indoor climate in the workplace. By not creating warm air, these systems do not cause unpleasant drafts - and where there is no draft, there is no dust swirl to pollute the air quality. Dust is almost everywhere - so this is an important plus for the well-being and health of your employees as well as for the protection of your production machinery. An advantage for the air quality is also the closed combustion of the infrared hall heating in the form of a dark radiator - and associated with this its property that exhaust air is specifically discharged to the outside and does not remain in the hall building. Incidentally, this waste heat can be used - with increased efficiency - for other thermal processes, e.g. for water heating (keyword: hybrid systems). 

How to control good indoor climate at work with infrared hall heating very specifically 

Infrared hall heating systems like KÜBLER's technologies are rarely simple stand-alone solutions today. They are digitally integrated into systems that enable a wide range of smart functions. In this way, different areas of use in the halls can be defined, specifically controlled and tempered according to need (keyword: zone heating). Intelligent efficiency modules detect open hall doors, for example, and automatically switch off the heating until the doors are closed again. Depending on the length of the door opening times, significant energy savings can be achieved. Today, switch-on and switch-off times are digitally optimized and entire heating processes are monitored and analyzed for audits, e.g. according to DIN EN ISO 50001. The air humidity can also be regulated - this is useful if you are storing corrosion-sensitive goods such as coils, for example. 

Create a pleasant indoor climate at the workplace with KÜBLER infrared hall heaters 

Infrared hall heaters can be used to solve the many climatic challenges of hall buildings - after all, they have been specially developed for this particular application and thus contribute a great deal to a pleasant working climate in the workplace. But they are more than the basis for a good and productive indoor climate in the workplace. Rather, infrared hall heaters today are designed to bring maximum energy efficiency to your halls. They are high-performance digital solutions that keep energy consumption so low that they pay for themselves both ecologically and economically. Through low CO2 emissions, favorable operating costs and low TCO (Total Costs of Ownership). That is why they are now one of the central building blocks of a sustainable financial and corporate strategy. 

If you too are interested in a hall heating system that not only creates an ideal indoor climate at the workplace but is also environmentally friendly, you should take a look at our KÜBLER infrared hall heaters. With our heating systems, you are not only making the right choice for your employees, but also for the future of the planet.

Smart heating controls - how digitalization is changing heat supply in industry and commerce

We live in a time of rapid change. Digitalization is increasingly determining our everyday working lives. For companies that want to be successful and competitive in the future, there is no way around it. When we talk about Industry 4.0, this is exactly what we mean: Machines and industrial processes are intelligently networked and controlled by algorithms. Many industrial companies have already implemented this or are on the way to doing so. But while the main focus is on production processes, other areas, such as heat supply, are usually overlooked. Rightly so? 

To Heat 4.0 with a smart heating control system 

The fact is that digital heat supply through smart heating controls can unleash great savings potential - especially in the industrial sector, where enormous amounts of energy, financial resources, but also manpower are used for heating. With "HEAT 4.0", we at KÜBLER have developed a concept that makes it easy to digitize your heating system with smart heating controls. Find out here what the industrial heating of the future will look like and what new technical possibilities digitalization with smart heating controls will bring. 

With a smart heating control system, the heat supply runs at an optimal efficiency level 

As a rule, heating systems in manufacturing plants and warehouses are switched on at the beginning of the heating period and off again at the end. In between, little happens for the most part. Between us: In very few companies there is time to regularly check whether the heating time is too long, the heating temperature is too high or the night setback is not regulated at all. The same applies to hall heating as to cars: the driving style determines the energy consumption. Therefore, the better adapted to the requirements of use, the more efficient is the heating operation. Smart heating controls that function fully digitally can take care of that for you at this point - they steer the heat supply through the winter with significantly less energy consumption, but at an optimal temperature level. 

Smart heating controls and intelligent tools manage the heating process and enable a completely new transparency 

These smart heating controls permanently collect data in real-time monitoring. This creates unprecedented transparency about the heating process. If you want to know which devices are active, how much energy they consume and when, whether the settings and efficiency values of your heat supply are still correct - now it is possible. In addition, the data collected by the smart heating control system is permanently analyzed and documented and is available to you, for example, for your internal quality management or for ISO 50001 or 14001 audits. 

Achieve increased availability of your heating system through smart heating control 

The interplay of digitized industrial heating systems and smart heating controls thus offers completely new possibilities in heat supply. This also includes predictive maintenance. Long before your hall heating system possibly malfunctions, you can see what is happening in the burner at the control station or on the monitor. You could have many interventions performed directly online, without the need for a service technician to make a trip. This would not only save an enormous amount of time and distance, but also increase the availability of your heat supply - and thus the safety of your production processes. 

Speaking of production, imagine what would happen if the heating system in production failed. Employee satisfaction and motivation will suffer - and in the worst case, production will come to a standstill for the time being. This can be remedied by early detection of possible malfunctions and failures through smart heating control. This also makes sense from an economic point of view, because heat supply today should be subject to the same cost-benefit consideration as any of your production machinery. 

With smart heating controls and intelligent networking, you save  

Industrial heating systems are no longer isolated solutions. They are networked with other technologies and themselves network the various energy flows in the building. This means that residual heat can be used to generate hot water and use it in sanitary rooms or to support hydraulic office heating systems. Waste heat from the production process can be integrated into the systems, as can energy from solar thermal energy and, and, and ... Building management systems or various software tools can be integrated into the smart heating control system and monitor, for example, the opening times of hall doors. And all of this is controlled across locations, regardless of the PC workstation. 

Smart heating control improves energy efficiency and reduces costs 

But digitizing hall heating systems with the help of smart heating controls not only offers you completely new technical possibilities. It also helps you identify and harness potential savings in the heat supply. Simply reducing energy consumption through extremely efficient infrared heating technologies and optimized operation with smart heating control can result in savings in primary energy consumption of up to 70 percent. These are dimensions that pay off significantly in business terms given the high consumption levels in industrial companies - with annual cost savings of up to six figures, depending on the company, at relatively low investment costs.  

Incidentally, this is also interesting to know: Legislation also rewards the high contribution to CO2 reduction and climate protection. In the Building Energy Act (GEG), the heat supply with decentralized systems (such as gas infrared heaters) in new buildings with a room height of more than four meters is exempted from the obligation to use renewable energies. 

New and economically very interesting services are only made possible by digital, smart heating control 

At this point, you should also get to know a new - and perhaps the most interesting - aspect of smart heating control: The heat supply can be rented. After all, the new, digital possibilities are particularly helpful when companies find themselves in the situation: Modern energy-saving heating technology? "Yes" - budget? "No." 

Many companies shy away from investing in a new heating system with smart heating controls and the associated depreciation expense. And that's understandable - especially in economically uncertain times. If the old heating system is then still running halfway - why not save the new investment? The digital age also offers a solution for this, which can be extremely interesting for companies: The digitization of heat supply enables completely flexible and very favorable rental concepts such as HeizWerk

With this rental concept, we assume responsibility for the heating process. And from energy refurbishment to operation. Via smart heating controls, such as intelligent remote maintenance software, we have a permanent overview of the heating processes and efficiency of the system and control it at an optimal level according to the usage profile. The company itself only rents the heat, so to speak - without the associated investment and depreciation requirements. At the end of the year, companies with such a rental solution therefore even have money "left over". This is because the energy cost savings are usually higher than the rental amount. So tackling the digitization of heat supply is also worthwhile in financial terms - making this sustainable and economically sensible decision palatable for every company. 

Our conclusion: Smart heating controls are simply part of the future 

They can help companies overcome the biggest challenges in heating halls - always with an eye on the future. Digitized heating systems, smart heating controls and the appropriate software tools ensure greater process transparency, increase energy efficiency, increase availability and at the same time reduce heating costs. And at a time when flexibility is also playing an increasingly important role, it is impossible to imagine life without digital solutions anyway. Only with their help can rental concepts be offered that enable heat supply without any capital expenditure at all.

Heating maintenance in the summer: 5 reasons why you should regularly maintain your heating system.

When the days get warmer, the heaters in production, storage and other hall buildings are also no longer needed for the time being. But after the heating season is before the heating season - that's exactly why the warm summer months are the perfect time to service your heating system to start the next winter without any problems or obstacles.

In this post, we've compiled five good reasons why you should service your heating system as early as possible.

Reason 1: It is mandatory that you regularly maintain your heating system

Various standards, technical rules but also the Building Energy Act recommend owners of infrared-based hall heating systems to maintain and service their heating system regularly. These are the most important ones:

  • Building Energy Act (GEG) § 60
  • Gas Appliances Regulation (EU) 2016/426
  • Technical rule for gas installations (TRGI)
  • DVGW Codes of Practice G 638-1 and G 638-2
  • German Construction Contract Procedures (VOB/B)
  • Ordinance on the sweeping and inspection of installations (KÜO)

In order to have legal certainty, the legal obligation by the GEG alone should be reason enough to have your heating system serviced annually. But let's look at four more good reasons why maintenance should have a fixed date in your fiscal year.

Reason 2: Increase availability and productivity by maintaining your heating system

A heating system is in operation for an average of 1,700 hours per year. Compare that with a passenger car. This operating time would correspond to a mileage of more than 100,000 km p.a. at an average speed of 60 km/h - unthinkable without inspection. The same applies to your hall heating system, which is why you should not refrain from servicing your heating system at regular intervals.

Starting with the good feeling of starting the next heating period safely. Although hall heaters from a brand manufacturer are heavy-duty and designed for reliable continuous operation, they also require regular replacement of wearing parts. A regular check is important so that you are not caught cold in winter and production has to come to a standstill in the worst case. If you always expect full functionality of your heater, you should maintain it regularly. In addition, heating maintenance is the best prerequisite for consistently high heating comfort, economical operation, low emission values, as well as for maintaining the value and long life cycle of your system.

Reason 3: Extend your warranty period by having your heater serviced under contract

Another point in favor of having your heater serviced is the warranty period. If your new heater has a manufacturer's warranty, it is usually tied to regular maintenance as well. Many manufacturers offer you maintenance contracts in this context. The statutory warranty period of one year on components in contact with fire is then increased to two years, for example, and the two-year warranty on components not in contact with fire is extended to five years. If you forgo the service contract and neglect heating maintenance, you also forgo this important benefit. So it's better to play it safe and have your heating system serviced.

Reason 4: Having your heating system serviced saves money and protects the environment

Infrared heaters heat highly efficient and energy saving. Depending on the hall project, you can reduce energy consumption and the corresponding costs by up to 70 % compared to conventional heaters. CO2 emissions can also be significantly minimized in this way. However, this economic and ecological advantage can gradually evaporate if you do not have your heating system serviced at regular intervals. An inaccuracy in the temperature display of 1 °C alone can cause an additional consumption of 5 to 7 %. In addition, impurities or a poorly adjusted burner can further reduce the efficiency of the heating system. Only if you have your heating system serviced and adjusted at regular intervals will energy be used efficiently and with low emissions. An annual service therefore not only saves trouble, but also cash. And: It ensures plannable maintenance costs at manageable fixed prices instead of incalculable costs in the event of a malfunction.

This makes it clear that anyone who does not have their heating system serviced is increasingly heating inefficiently. And energy efficiency is an important keyword that is firmly anchored in the climate protection targets of the EU and the German government. To achieve these goals, companies are required to reduce pollutant emissions in their heating and cooling supply. The basis for this is, among other things, energy-efficient buildings and appliances. Anyone who tackles their heating system maintenance in the spring or summer should therefore use it right away to uncover potential savings. After all, there is still time before the next heating season begins. Can the plant structure or hall layout be designed more efficiently? Can heating devices be optimized with new, digital components or even replaced with more efficient devices? There are many possibilities.

So, you should definitely schedule heating maintenance and inspection of your system if you want to reduce heating costs and increase efficiency. Finally, the CO2 tax has been in effect since January 01, 2021, making heating with fossil fuels more cost-intensive year after year. Build ahead here and keep your shop heating at optimal efficiency levels through maintenance.

Reason 5: Maintain heating and increase employee satisfaction

The heating check increases the operational safety and reliability of your heating system. If you have your heating system serviced by a professional as early as spring or summer, you will have plenty of time to fix any malfunctions. In this way, you can ensure that your system will continue to operate reliably in the next heating period - a real plus for your employees as well. After all, their satisfaction and productivity depend to a large extent on the right indoor climate. The guarantee for this you create with a 100% functional heating system.

Conclusion: There is nothing that speaks against maintaining your heating system at regular intervals

No matter how you spin it, there are no reasons against heating maintenance. But instead, many good reasons for it. More efficiency. Lower heating costs. Increased service life. Extended warranty protection. More operational safety and reliability. Higher productivity. And, of course, satisfied employees. With this in mind, it is best to commission your heating maintenance directly afterwards and benefit from all these advantages!
