Heating halls with 65 percent renewable energy - but the right way
February 14, 2023
Back in July 2022, the BMWK published its concept paper on the amendment to the Building Energy Act (GEG), thereby not only causing hopeless uncertainty, but also preventing investment in necessary energy-efficient renovations. First things first: the amendment has not yet been passed - and it is questionable whether it will actually be passed 1:1. Because if you trust Struck's law, a law does not usually leave parliament in the form in which it was introduced.
What is the concept paper "65% renewable energies for the installation of new heating systems from 2024" about? And what does this have to do with the refurbishment of existing heating systems in hall buildings? In this concept paper, the German government plans to make the use of 65% renewable energies mandatory from 2024. In addition, the maximum operating time of heating systems powered purely by fossil fuels is to be shortened from 2026. This means that heating systems will have to be replaced when they are 20 years old.
What does it mean for you and other operators of hall buildings if this concept paper is implemented? From our point of view as experts in sustainable hall heating, there are three options:
Option 1:
Replace your existing heating system in 2023 with one of KÜBLER's proven energy-saving systems, use condensing boiler technology where it makes sense, but save yourself the additional costs of a hybrid multi-energy system first.
Ergebnis: Die Modernisierungsmaßnahme wird Ihren Verbrauch an Heizenergie unserer Erfahrung nach um 50 bis 70 Prozent senken. Dies führt zu einer erheblichen Reduktion des CO₂-Footprints sowie Ihrer Verbrauchkosten, so dass sich die Investition i. d. R. in zwei bis drei Jahren amortisiert. Für die Zukunft bleibt Ihnen offen, die neue Heizungsanlage problemlos anzupassen, sobald Wasserstoff in ausreichender und bezahlbarer Menge verfügbar ist.
Option 2:
You opt for the high-efficiency system from KÜBLER, thus taking advantage of the hydrogen option and the possibility of upgrading the heating system at any time and easily with the retrofit kit for electricity or PV use. As a result, you can expect the same benefits as shown in option 1.
Option 3:
Sie investieren gleich in die CO₂-Freiheit mit einem Multi-Energie-System von KÜBLER, das Ihnen erlaubt, verschiedene erneuerbare Energieträger wie Strom oder Wasserstoff aber auch Gas oder Biogas variabel zu nutzen – im Mix oder alternativ.
Unter dem Strich gibt Ihnen diese Option die Freiheit, z. B. sofort auf eigenen PV-Strom zu setzen und sich dadurch ein Stück Energieautarkie zu eröffnen. Durch aktives Energiemanagement über die Steuerung machen Sie Heizkosten und CO₂-Ausstoß bei der Nutzung verschiedener Energieträger skalierbar – welch ein Fortschritt!
To summarize: it has never been so easy to implement the transformation to the carbon-free era in your hall buildings. And under economic conditions. This is because the investment is comparatively low - it is around 3 times lower than for heat pumps, for example. If you also use the lucrative HeizWerk rental model, you benefit from ultra-modern and highly functional hall heating technology even off-balance - i.e. without your own investment and depreciation costs. At the same time, your consumption costs will be reduced so significantly (usually by 50 - 70 percent) that you will have a cost advantage even when renting.
By the way:
The innovative multi-energy system was awarded the special prize "Innovative technologies for climate protection" at the SUCCESS technology competition at the end of 2022 and has been nominated for the German Innovation Award in 2023.

Anyone who operates one of the approximately 360,000 hall buildings that have been built in Germany since the 1960s has certainly already got cold feet this winter. It is quite likely that the heating systems in these halls are over 20 years old and are likely to cause regular malfunctions or even production stoppages. Not to mention the high heating costs or the trouble with employees and the works council.
