NEW: geothermal heat pump by Hidros Srl

High efficiency air to water air source/ground source HYBRID Split heat pumps with E.V.I. compressors

Heating capacity from 13 to 106 KW

The WWZ series of high efficiency hybrid heat pumps has been specifically designed for use with radiant floor heating systems or those applications where it is necessary to have maximum efficiency when heating.

They have been optimized on heating mode, are able to pro-duce water up to 65°C. WWZ units are available in 2 or 4 pipe (SW6) versions. Both versions can produce domestic hot water, in the standard WWZ through the activation of an external 3-way-valve and in the SW6 version by means of a separate heat exchanger and hydraulic circuit for the do-mestic hot water.

All models are supplied as standard with a reversing valve for defrost and cold water production in summer.

The main feature of WWZ units is that they have TWO heat exchangers on the source side (one air source, finned coil and the other a water plate type heat exchanger).

The unit is primarily an air source heat pump but both source exchangers will work in series at low ambient conditions to maximise the operating efficiency of the unit. The COP will be superior to a standard air source heat pump.
