LWI Indoor Air Source Heat Pump (10-35kW)

High efficiency air source heat pump packaged with integrated heat pump components! The LWI range of heat pumps is available up to 35kW high and with efficiency outputs up to a COP of 4.3.

A range of domestic hot water tanks and multi-heat tanks can be coupled to the heat pumps for maximum flexibility. Very small installation area – with no interconnecting refrigeration pipe work required, up to 60°C flow temperature and an excellent COP are factors in favour of the LWI range.

The LWI range of heat pumps can be used with standard steel panel radiators, underfloor heating, fan coil radiators and aluminium type radiators. The control system supplied with this heat pump can control solar thermal systems, electric P.V. integration, gas/oil boilers and heat input from wood fuel buffer systems.
