Hot Water Systems Heat Pumps Save up to 70% of your hot water costs

A heat pump is a new way to use renewable energy to supply hot water - and does not require solar panels on the roof. Heat pumps can save you substantial money on your hot water bills, as they use approximately one third the energy of an electric hot water systems. There is also generous rebates available making them an extremely economical alternative.

How does a Heat Pump produce Hot Water

Gas Hot Water Systems

A heat pump works by transferring heat not by converting electrical energy into heat.

A heat pump water heater removes energy from a low temperature source (ambient air or waste water) and moves it to a high temperature hot water tank.

Electricity is used to upgrade the quality (temperature) of heat energy not to generate heat energy

A heat pump is a little like a reverse refrigerator. It draws the heat in the air outside of the unit to the water stored inside the system through a heat exchanger. 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 in cooler months

To further improve the efficiency of the heat pump you can attach your heat pump hot water system to a solar booster.

Comparison of Electricity Demand

Heat pump peak electrical power demand = 500 to 1000W

Electric water heater peak power demand = 2400 to 4800 W

Rebates for Solar Hot Water Systems

There are many government rebates and incentives available to encourage people to switch to more environmentally friendly hot water heaters.

As of 19 February 2010 the Federal government rebate has now been reduced to $1,000 for solar hot water systems and $600 for heat pumps ,the rebate is not means tested, provided the eligibility criteria is met.

The NSW State government Solar hot water and Heat Pump rebate is $300 as of 15 January 2010 until 2011 for qualifying installations.

Government rebates can now be claimed for having a solar hot water or heat pump installed.
