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.
economic comparison of different heating methods 2019
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.
profitability of the main heating solutions on the market
- 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.
