Yanmar Gas-engine Heat Pumps (GHP) provide very efficient gas powered heating and cooling solutions for all kinds of buildings. By using world class Yanmar gas-engines to drive the system, these reversible air-source heat pumps can give low running costs, reduce CO2 emissions and use very little electricity.

The only difference from an Electric Heat Pump (EHP) air conditioning unit is that a gas engine rather than an electric motor drives the compressor. However, this one difference produces a number of major benefits.
