WHY WE DON'T FREEZE IN THE WINTER SUN.
Have you ever asked yourself why you don't freeze on a sunny winter's day in a ski hut, even in sub-zero temperatures? This is actually the principle of infrared warmth at work. When infrared warmth hits our skin, it instantly releases a pleasant sensation of heat, and it is therefore also called "radiant warmth". ETHERMA infrared heating systems are based on this principle of direct warmth. This technology provides particularly efficient heat, saving on energy costs and reducing the generation of dust.
HOW DOES INFRARED WARMTH WORK?
On a cold, sunny winter's day, you feel cold in the hut - but take a single step into the sunshine and it is suddenly pleasantly warm, even though there has been no change in the air temperature. In a sun-drenched ski hut, the favourite places to be are the walls - why is that? Here, so-called "secondary radiation" from the warm wall increases the sensation of heat even further.
Infrared heating is based on the principle of solar radiation. Thermal radiation does not primarily warm the surrounding air. Instead, ceilings, walls, objects and humans absorb the radiant heat. The environment stores the warmth, and releases this into the room (= secondary radiation). This homogenous warming of the room creates a pleasant climate, in which losses from rising warm air (as in convection heating) are largely avoided.
SNUGNESS IS MEASURABLE.
Infrared warmth provides not only direct heat, but also warms the walls, which then release the warmth again (so-called secondary radiation or the "warm walls" which you remember). An empirical investigation by Bedford and Liese provided that people feel the same degree of snugness with warm walls even when the room's air temperature drops. The sensed temperature is even 2-3 degrees higher than the actual room temperature. The room's air temperature can thus be reduced without affecting that sense of snugness. And every degree that the air temperature drops translates to an energy saving of approximately 6%. Thus, radiant heat can save you up to 18% in energy terms.
RADIANT HEAT VS. CONVECTION HEAT.
The invisible waves of infrared heat are absorbed by the solid objects and the walls in the room, and released into the room in the form of heat.
The resulting even room temperature ensures an optimal room climate and a particularly comfortable atmosphere. This is a complete contrast to convection, which only heats the air in order to generate a sense of warmth. The warm air first rises to the ceiling, where it cools down again before sinking to the floor - which wastes valuable energy.
EFFICIENCY - PROVEN SCIENTIFICALLY.
Following an energy-focused renovation, the heating burden drops so drastically that traditional heating systems cannot compete. Investment costs in alternative systems such as infrared heating are also significantly lower.
SNUGNESS IS MEASURABLE.
The Bedford/Liese snugness diagram shows that with warm walls, the same snugness is felt, even at lower room air temperatures. The room's air temperature can thus be reduced. Every degree that the air temperature drops translates to a 6% energy saving. Substituting convection heating with radiant heat can thus lead to energy savings of up to 12-18%.
Thanks to a precise control system with modern thermostats, you only heat where and when you want. This is also only possible with a heating system which generates warmth immediately after it is switched on. And that is when you want it. Flexible and independently of heating times, such as with those stipulated with community heating connections.
MODERN BUILDINGS ARE WELL INSULATED.
As a result, many traditional heating systems are often oversized and uneconomical. Where there is no demand for heat, it makes no sense to install an investment-intensive "power plant" - Heating and the heat requirement should match.
Solutions you can count on.
Following an energy-focused renovation, the heating burden drops so drastically that traditional heating systems cannot compete, as these are oversized and the cost of investment is too high. Investment costs in alternative systems such as infrared heating are also significantly lower.
IT'S WORTH COMPARING.
Consumption cost comparisons which only take operating costs into account often conclude that heating with electricity appears more expensive than with oil and gas, due to the higher price per kWh. But if you take into account the costs associated with capital and operation, infrared heating offers significant economic advantages. If you calculate the overall cost, comprising the investment, operating and maintenance costs over 15-20 years, no heating system comes out a clear winner in terms of price.
5 GOOD REASONS TO HEAT WITH ELECTRICITY.
Who doesn't want to be ahead of their time? In fashion, we obviously want to keep abreast of the latest trends, and our own four walls also follow architectural trends. But with heating, we often still lag behind the times. Here, it would be good to get back 'en vogue' or, with the right heating system, even get ahead of the times. Here are 5 good reasons why you should take another look at electric heating.
AN ENERGY AND TECHNICAL RENOVATION CASE STUDY: HOME RENOVATION
THE INITIAL SITUATION
An 80m² home was brought up-to-date in energy terms by installing new windows. This was exactly the right time to also bring the heating system up to date.
THE ETHERMA SOLUTION
The replacement achieved the following results:
Connected load reduced from 14 kW to 5 kW
New electricity tariff "Day/Night power = 8+14"
Consumption reduced by 1500 kWh - compared to an average of 4800 kWh for the six preceding heating periods. This resulted in a sensational 31% reduction in power consumption.
"I am very pleased with the result! In addition, the reduction in consumption came with a clear increase in comfort - cozy warmth throughout the entire house. A further positive side-effect was the air quality - additional air humidification is no longer necessary", explained the enthusiastic customer.
Electric infrared heating comprises an economical alternative, as it combines a lower investment cost with a reduced heat load.
IT'S ALL ABOUT LENGTH.
The word "infrared" (infra, lat. = beyond) makes it quite clear that we are referring to a range of electromagnetic radiation which lies beyond the red end of the visible light spectrum and is therefore free from UV radiation.
ETHERMA creates visionary technical devices to make optimum use of the highly efficient infrared radiation as a source of heat. This is why we have the right ingenious warmth solution for every wave range.
