What is aerothermal heating?

Air contains calories, even on the coldest winter days. In fact, it is only at the temperature of absolute zero (-273.15°C) that air no longer contains any heat at all. This means that, in theory, calories can be extracted down to that extreme limit. In our climatic conditions, outside temperatures rarely drop below -10°C. These “free” calories are therefore available even during the hardest winters.

Aerothermal heating technology collects this free energy and uses it to heat homes. This is done by using a heat exchange system made up of two units: an outdoor unit which collects calories and an indoor unit which supplies them to a water system of the “central heating” type. These calories are transported by a refrigerant which is circulated between the two units by a compressor. The only energy to be paid for is the power consumed by the compressor and a fan. Depending on the outside temperature, this energy represents only 25% to 50% of the heating energy distributed in the home. In other words, between 50% and 75% of the energy used for heating is free as it is extracted from the vast reserves available in the outside air.

 

 

An outdoor unit consisting of a fan and a heat exchanger extracts calories from the air. This heat is conveyed by the refrigerant to a generator which releases the energy required for heating. Heat is transferred in the home by means of a conventional hot water based heating system.
