Infrared power consumption and efficiency table

Die Tabelle zeigt die gravierenden Mehrkosten des Verbrauchs
if the efficiency of the infrared heating elements is poor

This table calculates the additional costs that arise with an infrared heating element with a lower efficiency than 70%. The highest costs arise at 40%, the lowest at 70% efficiency.

If the efficiency is below 40%, it is no longer an infrared radiant heater. The proportion of convection heat is then higher than the proportion of radiation. In the current reports on the DIN tests of the TU Dresden, heating elements with less than 40% efficiency are not listed.

Physically, a maximum of 70% (± 2.8%) is achievable due to losses during the conversion of electricity into heat.

Example: with a heating electricity consumption of 6000 kWh per year (approx. standard value for a single-family house) and a DIN efficiency of 50%, the energy loss compared to the ideal value of 70% is €548.54 per year.

With a useful life of 30 years, that is Additional costs in the amount of € 16,456.20 (without discounting, etc.).
