The innovation introduced by TEON in the field of heat pumps has made it possible not only to extend their application into the 'territories' of operation exclusive to boilers (high temperatures and radiator systems), but also to far exceed their efficiency. Efficiency is measured by the Coefficient of Performance (COP), which represents the ratio between the useful thermal energy offered to the system and the electrical energy absorbed. On average, the thermal energy offered is 4-5 times greater than the electrical energy consumed. In economic terms, this means an energy bill cut of 50% compared to a gas boiler and 70% compared to an oil or LPG boiler.
