HOW TO REDUCE THE COST OF YOUR HEATING BILL?
The DEGXEL heaters classified as the most economical solution in 2019!
At the request of the multinational construction corporation STRABAG, the engineering firm GENIO BAUPHYSIK gmbh, specialising in thermal analysis of buildings, was commissioned to undertake an independent comparative study.
The goal of this study (carried out in 2019) is to compare, over a period of 20 years, the profitability of the main heating solutions on the market.
Also, the engineering firm compared the following heating solutions within the frame of a new apartment (latest insulation standards) of 90 m2 located in Austria:
- DEGXEL HEAT4ALL far infrared heaters
- conventional water radiators (district gas heating)
- vented water radiator (hot water convectors)
- underfloor heating (water) associated with a latest generation heat pump.
All equipment taken into account in the study reflect high performances, each in its category. It is therefore a representative study in terms of the latest technologies, such as construction methods meeting the latest standards.
The study takes into consideration, for the whole heating season, a large amount of technical factors related to:
- the user comfort (apparent temperature, clothing, occupation, etc.)
- the intrinsic characteristics of the building (wind penetration, solar heat gain, variable climatic conditions, -15°C mini, etc.).
- the characteristics of the heating equipment (heat by convection, by radiation, etc.)
Unlike many summary comparative studies, all costs were taken into account (initial investment, operating costs, maintenance, depreciation, etc.) according to internationally approved calculation methods and for a 20-year horizon.
- The DEGXEL HEAT4ALL infrared heating is the most economical heating solution among all the solutions.
- Our solution is 8% more economical than the second ranked solution (heat pump + hydraulic underfloor heating).
Finally, bear in mind that these results were obtained due to the specific efficiency of DEGXEL radiant heaters (71% of radiation rate, emissivity, etc.). The results of this study cannot in any case be extrapolated to infrared heaters of less quality.

Important foreword on power/consumption
DEGXEL has been working in the low consumption field for years. So, let’s talk real! Some unscrupulous distributors let consumers know that the higher the power of a radiator, the better. This is totally false and absurd. The legislation requires that a nameplate be placed on all electrical appliances. Also, a radiator (just like a vacuum cleaner) is characterized by its electric power. This corresponds exactly to your consumption during a given period of use.
Power consumption in £ per day = Energy price (in KiloWattHour) x Power of the unit (in KiloWatts) x Number of hours of use
Unfortunately, this indicator provides no information on the efficiency of the heat emitter (radiator). Thus, the consumer has some difficulties in understanding that a 780W DEGXEL infrared electric heater can heat a room from 13 to 22 m2 with a better comfort than a traditional 2000W radiator.
The explanatory elements are simple:
- Ask any electrician around you, he will confirm that in the UK, the estimate of the power is based on one criterion: 100 Watts per m2 (for a standard height of 2.50 meters). Example: a room of 11 m2 will require an electric radiator of 1100 Watts. As old habits die hard, one will easily place a classic radiator of 1500 Watts (or even more!). If this radiator is of medium range and it is not equipped with radiation at least for a part of its heat emission, the phenomenon of convection will be major. As a result, comfort will not be there and you will tend to overheat to compensate. In conclusion, you will consume 1500 watts for a long time.
- For the same room (same conditions) DEGXEL will propose a radiator of 600 Watts which will be perfectly dimensioned. The heater’s radiation will reach all areas of the room (if properly positioned). Your consumption will never exceed 600 Watts, a gain of at least 40 to 50% in terms of consumption. Considering the price of Kwh in the UK, your investment is (in most of cases) amortized in less than 2 years with a much higher thermal comfort.
- In conclusion: on one hand the power requirements have a great influence on the final consumption, on the other hand our ability to offer you a wide range of low power radiators (210 W to 1020 W) helps you not to oversize unnecessarily.
The DEGXEL infrared radiators use the far infrared thermal radiation technology. Our technology allows you to achieve your heating projects with a power requirement from 60 to 65 Watts per m2 (on average). Note that conventional convectors consume about 100-130 Watts per m2 to heat the same surface and that conventional radiators (including top of the range) consume between 90 and 100 Watts per m2.
What you will pay with DEGXEL radiators
The following table shows the consumption of DEGXEL heaters with the following assumptions: apartment in London of 100 m2, very good level of insulation-orientation, to maintain the temperature of comfort already reached with £0.18 Exc.VAT / kwh (average off-peak hours) with a comfort temperature of 20°C.
Your consumption / Example: room of 10 m2 => average standard conditions (60 Watts per m2, or 600 Watts) => 600W DEGXEL heater => Consumption = £0.5 per day
