With electricity prices escalating to an all-time high and South Africa increasingly facing energy supply problems, going solar is the way to go. More and more people have come to realise the value of harnessing the energy of the sun – for free.

The first step to cutting electricity costs and to undertake your solar conversion, start with a solar geyser.

Electrical geysers account for a large portion of your electricity consumption – up to 40 – 60 % of your electricity bill. By installing a solar geyser, you can drastically cut your monthly expenditure on electricity and energy use.

Solar geysers harvest energy from the sun to heat stored water, and that does not cost a cent.

Choosing a solar geyser
Solar water heaters are manufactured as high pressure and low-pressure models. With high-pressure solar geysers, water in the tank is under high pressure, equal to the pressure of water from a tap. In a low-pressure solar geyser the water in the tank is under low pressure and is equal to the gravity of the water. There are some fundamental differences which you should be aware of before deciding which one to buy and install.

Low-pressure solar geyser
Low-pressure solar geysers rely on glass tubes connected to a tank with a small holding tank on top of it. The glass tubes are filled with water and exposed to the sun, heating up the water in the glass tubes. Hot water is forced up the pipes to fill the tank, pushing the cold water back down into the tubes for re-heating. This type of geyser is simple to install, lightweight with no moving parts and very effective in heating water.
It should be installed high up, for instance on top of the roof, to get the maximum pressure.

High-pressure geyser
A high-pressure solar geyser is designed to supply high-pressure hot water. A high-pressure solar geyser is usually an enclosed heating unit containing copper tubes connected indirectly to a tank.
Most homes have high-pressure municipal water supply. The high-pressure solar geyser features evacuated tubes and a heat pipe. The evacuated tube absorbs solar energy from the panel and converts it into heat energy. The water in the tank is under high pressure, equal to the pressure of tap water.

Enlist the assistance of professionals to install your solar geyser for optimal efficiency. Once installed, little maintenance is required
