GAS ENGINE HEAT PUMP BENEFITS - HEATING MODE

Typical Boiler

Heat PumpReversible cycle provides heating and cooling with

renewable energy as heat source.

EFFICIENCY > 100%

A gas boiler provides heating only from the energy input.

ENERGY INPUTGas for gas-boiler

EFFICIENCY UP TO ABOUT 90%

Electricity for Electric Heat Pump

Gas for Gas Heat Pump
