System advantage
The engine waste heat, which is normally exhausted into the atmosphere, is recovered via the heat exchanger and effectively used as hot water, so the GHP chiller acts as a sub system that alleviates the load on the client's main hot water system and therefore offers ‘free’ hot water.
