Aged Care Hot Water Boost

The client had an existing underfloor heating system which was driven by aging air to water heat pumps. The system wasn’t performing well and was unreliable at critical times. The system was designed with two much larger heat pumps, this designed required that quite often one heat pump was off and the other was short cycling because the load of the building was lower than what one unit on low modulation could provide. The revised design allowed a much wider modulating range both reducing running costs and increasing reliability. Moving to a more advanced control system also allowed the client to run the system in cooling mode during the summer, which greatly reduced the load on the air based cooling system - increasing the comfort and reducing the overall running costs.
