Split : The heat pump consists of two elements
(an outdoor unit for outside and a hydraulic unit for
inside the dwelling).
Air/water : The surrounding air is the energy source.
This energy is transmitted to the water in the heating
circuit by the heat pump.
Inverter : The fan and compressor speeds are modulated
according to the heating requirements.
This technology enables you to save on energy and
operate on a three-phases power supply, whatever the
heat pump's output, by avoiding heavy intensities on
start-up.
COP (coefficient of performance) : This is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.
