The Siddons SolarPlus solar-boosted heat pump water heater first entered the Australian market in 1989. It was the first residential heat pump water heater in Australia and one of the first globally. The black panels seen in the photo above contain refrigerant and absorb solar energy to produce energy-efficient hot water.

The black panels seen in the photo above contain refrigerant and absorb solar energy to produce energy-efficient hot water.
The Siddons SolarPlus was developed by Siddons Energy Systems, a division of Siddons Ramset Ltd. This product later became the Quantum Energy heat pump after the Siddons family bought the business.

Heat pumps are where Sustainable ES started. Today, we are known for helping families with batteries, solar power, HVAC, and, of course, hot water.

Heat pumps are where Sustainable ES started. Today, we are known for helping families with batteries, solar power, HVAC, and, of course, hot water. Michael Siddons designed the first air-source heat pump water heater, the Quantum Energy Heat Pump, in 1994. It set a new benchmark for energy efficiency. Eventually, the convenience of the Quantum All-In-One heat pump made the older Solar-boosted design obsolete, and Quantum has remained a leading heat pump water heater for many years.
