Heat Pump


How does it work?

It is a system that uses the principle of thermodynamics. It transports the calories (heat) contained free of charge in the air from one place to another, thanks to a hermetic refrigeration circuit.

Owned by AFNOR Certification, this mark is part of a quality and performance approach to heat pumps. It ensures, through laboratory tests and audits of the manufacturing plants, that the requirements defined in the Certification Standards (NF 414) are met. The essential certified characteristics are: the coefficient of performance (COP), with a minimum threshold (depending on the type), the heat output and the announced sound power level (COP = energy performance of the pump operating in heating mode).
The NF PAC mark is a voluntary mark, issued by CERTITA, an organisation mandated by AFNOR Certification. Some HITACHI products have been awarded this mark. They are presented with the NF PAC logo.
