Choose infrared heating systems from ETHERMA and reduce your energy needs and costs. The ideal complement to your existing heating system!
The energy transition is in full swing, also due to political requirements. In Germany, at least 80 % of gross electricity consumption is to come from renewable energies in 2030; in Austria, the target is 100 %. This is accompanied by a reduction in CO2 emissions from fossil fuels. ETHERMA has been playing a pioneering role in sustainability since the 1980s: cleverly combined with environmentally friendly electricity, ETHERMA electric heating systems help to reduce CO2 emissions.
Do you need to take action?
Legal requirements in Germany and Austria stipulate that a minimum temperature must be maintained in workplaces, whether in halls or offices.
Depending on the activity, this ranges between +17°C and +25°C.
If these values cannot be achieved with the existing heating technology, additional measures are required, e.g., infrared workplace heaters, zone heating, or heating mats.
ETHERMA infrared heating systems provide precisely the right amount of heat – energy-efficient, maintenance-free, and ideal for combining with photovoltaics. This allows you to increase the proportion of renewable energies in your heating system while continuing to use your existing heating system.
Conventional gas hall heaters warm the air throughout the entire room.
Modern infrared heating systems heat specific workstations and areas in use – not the entire hall.
With ETHERMA you can comply with all regulations, at the same time reduce the room air temperature and thus costs, and your employees will feel completely comfortable thanks to pleasant radiant heat.
Conventional hall heaters are usually convection heaters. In order to achieve a comfortable heat near the floor, hot air is blown from the ceiling. Due to the heat losses until the heat reaches the ground, the temperature must be much higher, which means more energy input. In addition, there is the swirling of dust and bacteria. Infrared heat is different: When infrared rays hit solid materials (such as bodies or walls), they are heated immediately. A pleasant feeling of warmth is created immediately – to be compared with a sunny winter day: if clouds cover the sun, you feel cold. As soon as the sun comes out, it is warm, although the ambient temperature has not changed.
The experiment according to Bedford and Liese confirms: With warm walls, people feel the same comfort despite lower room temperature. The subjectively felt temperature is 2 °C to 3 °C higher than the actual temperature. Thus, the room temperature can be lowered without losing comfort. Every degree less room temperature saves about 6 % energy. Consequently, infrared heat can save up to 18 % energy.
Workplaces in halls and offices can be heated much more selectively with infrared than with conventional heating systems. Especially in halls, cold, unpleasant drafts through open doors prevent a pleasant working climate. Infrared heat solves this problem, because the indoor climate is not created by warm air, but by heat radiation. This heat does not change due to air drafts.
Thanks to punctual infrared heat, you can warm up your workplace in the way you find comfortable. And only if the workplace is actually occupied. Other advantages: fast heat-up time, low investment costs, no maintenance, no technical room, no fuel storage, no complex pipe installation.
Up to 18% energy savings through highly targeted heating
More comfort and coziness at every workplace
A comfortable climate even with doors/gates open
Short heating time and precise control
Reduction of CO2 footprint, no maintenance, no fuel storage
In large halls, continuous heating is often energy-inefficient and economically unattractive.
With infrared zone and workplace heating systems from ETHERMA, you can concentrate heat exactly where it is needed:
> Spot heating for individual workstations
> Zone heating for defined hall areas
This significantly reduces energy consumption and heating costs, while your employees benefit from pleasant, even radiant heat.
Depending on the height, use, and insulation of your hall, ETHERMA offers the ideal radiator solution for room heights of up to 9 m. All variants are energy-efficient and specially designed for large-volume rooms—available for ceiling or wall mounting.
Conclusion:
With the right combination of heater type and heating strategy – whether spot or zone heating – you can use your heating system with maximum efficiency and significantly reduce your operating costs.
Ideal for individual workstations in high-ceilinged halls
Heat radiation ideally comes from two directions for even coverage (overlapping).
High heat intensity even at reduced mounting height
For larger work areas in large halls
Heater distance from exterior walls ≤ 50% of the installation height
Save energy by heating only the areas that are actually used
To heat the workshop efficiently, Van Velzen relies on ETHERMA EEZ infrared heaters with high surface temperatures.
A total of 20 infrared heaters (2 kW each) were installed in the upper hall area and 4 infrared heaters (1.6 kW each) in the lower hall area, which are controlled by 2 thermostats.
The thermostats have a touch display and can also be controlled via a handy app, which makes heating even more convenient.
In this regional textile sorting center, the use of gas heating repeatedly caused problems: dust swirling around the air impaired air quality and caused health problems among employees.
ETHERMA’s solution was to install 28 EEZ-2000 infrared heaters with a total power of 56 kW. In addition, ETHERMA designed both the electrical cabinet and a detailed installation drawing to ensure smooth and fast assembly.
Conclusion: Employees benefit from noticeably better air quality and even heat distribution – without any of the disadvantages of conventional hall heating.
This production and logistics hall demonstrates how significant energy and cost savings can be achieved through a targeted combination of temperature reduction and ETHERMA infrared auxiliary heating.
The hall was previously heated entirely with gas, with a room temperature of around 22°C.
The goal was to reduce heating costs without compromising comfort in the workplace.
Solution
The solution was to lower the overall room temperature in the hall from 22°C to around 18°C and, at the same time, install ETHERMA EEZ infrared heaters with an output of 800W in specific locations at the production workstations.
This means that heat is only generated where it is actually needed – directly at the workplace.
The result: Gas consumption fell by around 20% or 39,080 kWh per year. Employees continue to benefit from pleasant radiant heat, while heating costs and CO₂ emissions have been significantly reduced.
Total area: 1,552 m² (of which 688 m² is production space)
Construction period: 1985–1990
Hall height: approx. 4.5 m
Production workstations occupied: 12
Conversion in 2021: 6 EEZ 800 W heaters
Heat requirement according to building type C: min. 210 W/m²

In addition to reducing heating costs by lowering the room temperature while integrating electric heating, the installation of a PV system can sustainably reduce electricity costs. A 38 kWp system generates enough electricity to cover the power requirements of the electric heating system in a hall with 12 production workstations, even in the month with the lowest yield.

The microclimate refers to all environmental influences in a room that affect the heat exchange between people and their surroundings. In addition to humidity and fresh air supply, room temperature is also crucial:
If the workplace is at the right temperature, the body does not need to expend additional energy to maintain its normal temperature of around 37°C.
ETHERMA infrared panels deliver pleasant radiant heat exactly where it is needed – directly at the workstations.
Compared to conventional convection heaters, which unnecessarily heat up the entire room, infrared solutions are more energy-efficient and healthier.
ETHERMA offers the right heating systems for comfort and energy efficiency, not only for halls, but also for offices and other indoor spaces. It is often difficult to maintain a comfortable temperature for all employees, especially in open-plan offices, reception areas, or showrooms.
With LAVA® infrared heaters from ETHERMA, temperatures can be regulated individually at each workstation – regardless of the ambient temperature.
In times of flexible offices, where workstations are not continuously occupied, this technology offers a decisive advantage:
In the home office, targeted heat is more important than full heating.
With ETHERMA LAVA® infrared panels and the LAVA® DESK ZONE, you only heat your workspace – not the entire room.
The LAVA® DESK ZONE is a clever set consisting of a table-mounted and under-table infrared heater.
It provides pleasant radiant heat for the upper body, legs, and feet—immediately noticeable, without any drafts or dust swirling around. Ideal for concentrated work at a lower room temperature.
Instead of keeping your study at a constant 23°C, lower the temperature and only switch on the infrared heating when needed.
This saves energy, reduces costs, and ensures noticeable comfort in the workplace—whether in your home office, co-working space, or office.
Huiskes-Kokkeler Autogroep is a group of car dealerships with a total of about 250 employees.
LAVA® DESK infrared heating panels from ETHERMA, mounted on the underside of the table, are used to heat the workplaces near external doors and open areas in the showrooms.
Thus, the comfort of employees is increased by targeted and individual heating of workstations. At the same time, energy costs are reduced, as it is no longer necessary to heat the entire premises.
As a condition of a multi-year lease, the new tenant required the landlord to replace the old convection heaters and night storage heaters with a forward-looking, efficient heating system.
A solution with more heating comfort and lower operating costs was required. In addition, the new heating system should also be flexible in terms of installation position to leave more space for desks and shelves.
The old heating systems were replaced with LAVA® infrared heating panels. Each room is treated as a separate zone and controlled by a programmable thermostat. The lessor also benefits from the long service life and does not need to worry about maintenance or service costs. Because there are none.
Work comfortably – even at lower room temperatures
A study shows that if the room temperature in an office with eight people is lowered from 22°C to 18°C and additional electric heating is used selectively at workstations, the total energy requirement is reduced by around 30%.
According to TU Dresden, thermal comfort can be achieved with infrared heating of just 120 W per workstation.
The result: operating costs from just €45 per workstation per year – with complete comfort.*
Low operating costs: from as little as 45 euros per workstation per year
Particularly targeted and efficient heating of office workplaces
