Solar hot water systems classifications come in 3 different varieties

Split Solar Hot Water Systems

This is where you only have the solar panels on the roof & your hot water storage cylinder in at ground level, water flow through the panels with the help from a small circulating pump connected to the tank (which uses very little power & has no noise) & comes on & off when the panels reach higher temperatures than the cylinder, this is controlled by sensors connected to a control board, all very simply designed.

Above shows what you could expect your roof to look like whether you have a flat, tiled or iron roof.

Roof Mounted or Close Coupled Solar Hot Water Systems

As the name suggests, the hot water storage cylinder is located on the roof & connected direct to the solar panels, not the most aesthetically pleasing thing to have on your roof & with the weight most roof mounted solar hot water systems weigh just over 500kgs when full of water, being approx. 1.8m in length this means this weight could be beared on only 2 or 3 roof trusses.

Roof mounted solar hot water systems use thermosyphone to transfer heated water from the panels to the storage cylinder, hot water naturally rises from the panels to the tank. unfortunately in hot sunny summer days this can cause the system to overheat which in turns water is dumped out via the temperature relief valve & may cause lot of water wastage.

Heat Pump or Air Sourced Solar Hot Water Systems

An air sourced heat pump is sort of new technology to Australia, really only coming to the market in any numbers around the 2006 2007 era when compulsory regulations for environmentally friendly hot water systems was introduced for the new home market.

Heat pump hot water heaters work like a refrigerator or air-conditioner, but in reverse while a refrigerator pushes heat from inside the unit out to the air around it, a heat pump water heater uses fans and an evaporator to pull warmth from the surrounding air and transfers it to water in the storage tank. The energy required for this process is 3 to 4 time less than the energy it recovers from the surrounding air. A good heat pump hot water system that uses 1kwh of electricity supplies more than 3kwh of hot water.


We don’t sell DUX Airoheat heat pumps at all, they are the worst of them all, Rheem & Quantum are also not that crash hot.

You need to be very careful when investing in these types of water heaters, stay away from unknown imported brand names & cheap systems from China like the Hydrotherm or Aquatech products, imported by a Gold Coast company & after only a couple of years here are not proving to be durable, this same product is badged under the Chromagen Midea, check the photos below!

The European made heat pumps from German companies Bosch & Stiebel Eltron are by far the best two available & probably the only two we would sell confidently for being reliable & efficient in running.
