Hot Water Heat Pumps

Hot water heat pumps are very efficient hot water heaters and are a significant low-cost way to reduce your carbon footprint by using up to 75% electricity to generate your hot water as compared with a conventional electric hot water system.

This revolutionary invention was initially developed in the 1970's at Melbourne University, and since that time there have been a steady development of innovative technological advances which have resulted in world leading products that will save you money and reduce your environmental footprint.


One of the most important breakthroughs is the quick hot water recovery, even at night, or with low outside ambient air temperatures, and without the need for gas or electric element boosters such as with solar collector hot water systems.

Heating hot water accounts for up to 30% of the average homes energy bill which makes producing hot water the largest source of greenhouse gas emissions in the home.

Installing a heat pump will reduce the amount of greenhouse gas emissions and reduce your cost to produce hot water by up to 75% when compared to other hot water systems.

The ongoing product development over 30 years now ensures worry free operation for hot water heat pumps. They are comprised of the fan an evaporator a compressor and an expansion valve monitored by electronic controller.

Heat from the MBF here is absorbed by an environmentally friendly refrigerant in the evaporator will stop this refrigerant gas is then compressed which causes the gases temperature and pressure to be raised. This hot gas is passed through copper tubes wrapped around the outside of the water tank as the condenser. Heat is then transferred from the tubes to the water inside the tank.

Once the heat from the compressed gas has been transferred to the water in the tank, the gas becomes a liquid again as it has lost its heat. This liquid gas then passes through an expansion device and back to the evaporator. The cycle is then repeated until the water in the storage tank reaches the set temperature.


A heat pumps efficiency stems from the fact that only minimal electricity is required for the compressor, fan and digital display panel. It works in temperatures from as low as -10°C up to 40°C both day and night very efficiently without the need to boosting.

The heat pump principle is simple and can be compared to a refrigerator, but in reverse. It extracts latent energy from the air and transfers it to the heating system. This free energy from the environment is converted into useful heat the heat the water in the tank. In other words, you are using free energy from the environment that doesn't cost a cent, and at the same time reducing your carbon footprint.

hot water heat pumps save you energy, money and reduces greenhouse gas emissions once installed. State and Federal governments are also rewarding those who install greenhouse friendly technologies. There are many financial incentives available.
