Some suppliers offer electric underfloor heating which they claim to be 30-50% more efficient than ormal electric underfloor heating systems. Are they?
The truth is very simple, with any mains voltage electric heating system one kilowatt of electricity will produce one kilowatt of heat, whether it is a 3mm or 7mm cable, heating mats or heating ribbons. With a low voltage system there is a small amount of wasted energy in the form of heat and noise within the transformer. The only things which significantly affect the cost of running one system compared to another are the insulation used beneath the system, the output of the system and the use of an intelligent thermostat. In general, the better the insulation used beneath it, and the higher output of the system, the cheaper it will be to run as long as it is used with an intelligent thermostat like Heat Mat’s NGT thermostat/timer.
