Space heaters - Solutions for event and exhibition halls
Whether concert fan, art lover or party enthusiast: the room temperature also determines the success of events. How hosts ensure a feel-good climate with hall heaters in event halls and exhibition rooms.
Concerts, art exhibitions and corporate events are increasingly taking place in unusual locations - for example in old fish factories, heating plants or in tents on historic factory sites. The ambience: often a mixture of rustic and modern. An atmosphere that only unfolds, however, when the temperature is right. After all, who likes drinking Chardonnay with cold feet? Or eat a salmon appetizer with a hypothermic nose?
That's right, no one. And that's why most event organizers strive for a comfortable feel-good temperature. They are experimenting with various heating solutions. For example, with mobile warm-air heaters that blow heated air into tents via warm-air hoses. Or with mushroom heaters, near which guests warm themselves with a gas flame.
The problem: Many hosts are not really satisfied with warm air systems as hall heaters.
Because warm air has a mind of its own. It distributes itself unevenly in halls and tents, mixes with cold layers of air, creates a draft on the legs, arms and necks of the guests. "Honey, do you think we might want to leave so slowly?", this sentence is then uttered far too early in the evening at worst. Not the only shortcoming.
The electricity bill is also often unnecessarily high. This is because warm air flees toward the ceiling - in other words, where it is of no use to anyone and only causes energy costs. Implementing different temperature zones, such as a cool zone at the buffet and a warmer one in the lounge areas? Virtually impossible with air that is constantly mixing. Last but not least, many warm air systems as hall heaters look less chic, more like relics from the 1980s. They often cannot be integrated into a modern environment without a visual break. And in the worst case, they are so loud with their humming and hissing that they disturb the ambience.
Targeted and economical heating: infrared heaters reshuffle the cards
For hosts for whom warm air systems are not enough because they are too loud and unattractive, eat up too much energy and do not even satisfy many guests, there is an alternative solution: Infrared heaters. The hall heaters reshuffle the cards when it comes to heating event halls and exhibition spaces. Why?
Because their principle of operation is fundamentally different from warm air systems. For example, infrared systems do not heat the air. Instead, they generate electromagnetic waves that convert into heat as soon as they hit solid bodies - such as guests or tables, benches and stages. The advantage: hosts no longer have to heat all the air in a hall or large tent to create a comfortable temperature, but can focus specifically on the area of use. Since this is usually many times smaller, you save a massive amount of energy. But that's not all.
Bringing the pleasure of pleasant sun rays indoors
Do you know it? You go for a walk on an autumn day. The air is pleasantly cool, but at the same time you feel the warm rays of the sun on your skin. A feel-good atmosphere that infrared heaters also create indoors. Guests find the infrared heat particularly pleasant because it corresponds to the natural heat principle of the sun - without dry heating air, dust swirls and drafts.
Also the eye does not come too briefly. Modern infrared heaters can be discreetly integrated into the surroundings or highlighted as a design element in their own right. In addition, the hall heaters operate as quiet as a whisper and would not even disturb Ludwig von Beethoven's 15th string quartet. They are therefore perfect for tempering large tents, event halls and exhibition rooms.
Hamburg fish auction hall pampers guests with infrared heat
Do you know the fish auction hall at the St. Pauli fish market? It is a magnet for night owls and tourists from all over the world. That's because every Sunday, starting at dawn, visitors come here to buy fish rolls and other delicacies from hundreds of food stalls and food trucks. They enjoy eating and drinking in merry gatherings on beer benches in the fish hall - with live music until twelve o'clock at night. An inviting setting that is also appreciated by organizers of cinema festivals, theater and reading days, and the multi-day Light Festival. Events are regularly held in the 4,100 m2 hall, with up to 4,200 people.
And the temperature in the fish auction hall is always right. That's because the operators have installed OPTIMA series infrared radiant heaters, painted to match the style of the architecture and suspended from specially designed, invisible wire cables. The units warm the 103-meter-long and 23-meter-wide hall, which is eleven meters high at the dome, with a total output of 700 kW. The heat from the hall heaters is concentrated specifically on the area of use, i.e. on tables, benches, food stands and, of course, the guests themselves.
The thousands of cubic meters of air above this area, on the other hand, are cool without disturbing anyone. The visitors' ears are also spared any annoying noise. KÜBLER supplied the radiant heaters in super-silent design and additionally soundproofed the exhaust fans. Thus, the noise effect is reduced from industry standard almost to concert level.
Fish auction hall saves 50,000 euros in heating costs per year
But the operators of the fish auction hall not only benefit from a modern, inconspicuous appearance and quiet operation of the hall heaters. OPTIMA also reduces energy consumption in the fish auction hall - by up to 50 percent compared to conventional systems. Even more energy can be saved with the R.O.S.S.Y digital control system, as heaters can be controlled with pinpoint accuracy and preheating times can be reduced to an environmentally compatible minimum in line with weather periods and seasons.
The bottom line is a heating cost saving of 50,000 euros per year. And extrapolated over the life cycle, a saving of 19,830 MWh of primary energy. Enough power to heat around 700 average households for a year.
KÜBLER infrared heaters are also used in the Tresor, a disused heating plant in Berlin's Mitte district. Now on six levels, connected by staircases and mezzanines with numerous rooms and niches, there is over 20,000 m2 of exhibition and event space for contemporary music, art and culture. Space that needs to be heated. For this purpose, the operators initially planned a warm-air heating system. But it quickly became clear that too much energy would be lost due to the expected thermals in the direction of the roof.
The alternative: 20 black-painted infrared heaters from the OPTIMA series. The radiators, however, are only part of the heating solution. A heat exchanger called O.P.U.S. X also plays a role. It makes it possible to use the residual heat from the infrared radiators in the H.Y.B.R.I.D. system to heat water, for example. The operator of the vault recovers up to 15 percent of the energy that was previously lost to the environment in this way.
