Why Heat Pump Hot Water?
Heat pump hot water systems use ambient air to heat water, consuming roughly one-third the electricity of a conventional electric storage system. For a household of 2.5 people using around 125 litres per day, a heat pump can cut hot water energy costs from $700 down to $200 annually. In warmer climate zones, heat pumps are even more efficient due to higher ambient air temperatures.
STCs (Small-scale Technology Certificates) reduce the upfront cost of a heat pump by $800 to $1,200 depending on your location. Each suburb page shows the applicable climate zone, estimated demand, and running costs to help you compare options.
