How does it work?

Solar hot water systems use the sun’s energy to heat water in much the same way as water in a hose gets hot on a sunny day. In a direct heating system, water is heated as it circulates through flat, glazed panels (solar collectors), located on the roof of a house.
The heated water is then stored in an insulated storage tank, located either directly above the collectors or on the ground like a conventional hot water system.

An auxiliary heater is also included in the system, to boost water temperature on days when solar energy may be insufficient to meet all of your hot water requirements. Boosters may be run on off-peak electricity, gas (natural or LPG) or solid fuel.

Close-coupled solar hot water systems

This is the most common system on the market. It consists of roof-mounted solar collectors, combined with a horizontally-mounted storage tank located immediately above these collectors. In most solar systems a pump is not required. Heated water rises naturally through the solar collectors and enters the storage tank. When this happens, cooler water at the base of the storage tank is forced out and flows down to the bottom of the collectors. This cycle is continuously repeated while the sun is shining. Most commercially available solar hot water systems employ this cycle, commonly referred to as ‘thermosyphon flow’.

Split system solar hot water

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.
