Hybrid Heat Pumps
LWZ
High efficiency air to water air source/ground source HYBRID heat pumps with E.V.I compressor Heating Capacities from 26 to 100 kw
The LWZ 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 produce water up to 65°C and can operate down to -20°C ambient temperature. LWZ units are available in 2 or 4 pipe (SW6) versions. Both versions can produce domestic hot water, in the standard LWZ 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 domestic hot water.
