There are three different types of solar water heating systems. They are Low Pressure Compact, High Pressure Compact and Split pumped systems.
The low pressure compact systems comprise of a geyser and a Solar Collector that are directly connected. The water is heated in the glass tubes and naturally rises, convection takes place and the hot water collects in the geyser or storage tank.
An electrical backup can be fitted to heat the water on poor days.
Low pressure does not refer to the water supply and simply means that the hot water is delivered at gravity and subsequently the system has to mounted above the taps,preferably on the roof or a stand of some description.

PRICES EXCLUDE VAT AND DELIVERY.
The high pressure compact systems comprises of a storage tank and a solar collecter. It is also known as an indirect system because there is no water in the glass tubes. The water in the storage tank is heated by heat transfer pipes in the tubes that plug into a heat exchanger in the storage tank.
Again an electrical backup and an electronic controller can be fitted to cope with poor weather and overusage.

We do install and that normally works out at about R2000.00.
The split pumped systems circulate water from the existing storage tank through the solar collector and back to the storage tank. No water is in the glass tubes and the system is basically a heat exchanger. The pump is Solar driven and works happily while there is enough energy to heat the water.
The storage tank is connected to a power supply that seves as a backup and is controlled with and electronic control panel.
