Heat Pumps / Hot Water Systems
A heat pump is a little like a reverse Air conditioner. It transfers the heat from the air outside of the unit to the water stored inside the heater. This proses occurs through a heat exchange system. In the case of heat pumps, “heat” is a relative term as they will still work in very cold conditions. At least -10 degrees Celsius, so it will still be generating hot water for you during winter nights.
If you’re looking for an energy-efficient means of providing your home with hot water, the heat pump systems are great. Engineered to run on low energy costs. Market leader, of hot water heat pumps harvest natural energy from the air to efficiently create hot water. Unlike solar systems, hot water heat pumps in Australia don’t rely on a steady supply of sunlight in order to operate. – instead, they work at all times of the day or night and in all weather conditions.
Running Cost – Heat Pumps
Hot Water Service Heat Pumps can be Cheaper to run than other hot water services. In many cases, they can be cheaper to run than a solar hot water system on your roof.
Heat Pump Water Heaters
In Australia, HPWHs make up around 3 percent of water heaters in use. At the time of the 2012 product profile, there were approximately 18 brands and about 80 separate models of HPWH on the market in Australia, and 9 brands and 25 models in New Zealand.
What is a Heat Pump Water Heater?
Heat pump water heaters absorb warmth from the air and transfer it to heat water. They can also be referred to as air-source heat pumps. They operate on electricity but are roughly three times more efficient than a conventional electric water heater. When used in the right environment they save energy, save money and reduce greenhouse gas emissions.

How does a heat pump work?
A heat pump is a little different to a traditional solar hot water system. Heat pumps use heat energy from the air around us to heat water.
The basic principle of a heat pump is a reverse refrigerator. It uses a working fluid that vaporises as it extracts heat from the air. The working fluid then transfers this heat to the water in the tank via a coil in the tank. As the working fluid is pumped around the coil, it releases heat to warm the water. The release of heat turns the vaporised fluid back to liquid and the cycle begins again.
While a fridge uses the cold air and discards warm air, the heat pump uses the warm air and discards the cold air. Compared to hot water created through fossil fuel, the heat pump only requires 30% of the energy for the electricity to run the pump. Therefore, around 70% of the energy required to create the hot water comes for free from the heat in our environment.
A heat pump works on the same principle as a refrigerator, but instead of pumping heat out of the fridge to keep it cool, they pump heat into the water.
