Electrical hot water geysers are responsible for the biggest portion of your electricity bill.

Solar geysers heat the water without any electrical connection at all. Electricty bills can be slashed by a huge amount.

Heat pumps can save around 40 % of an electricity bill. An electric geyser uses 3 units of electricity to generate 3 units of heat energy, a Heat Pump uses 1 unit of electricity to generate 3/4 units of heat.

Heat pumps are useful in places with a lot of shading. In commercial environments such as an hotel, mine or factory where large volumes of water are being heated, savings on electricity can be as much as 70 %.

Typical Savings in a household:

Solar Geysers save electricity billsSolar Geysers heat the water without any electrical connection. In many instances they also have an electrical element as back up for when there is insufficient sun light to heat the water adequately. This is ideal where e.g. all hot water is used at night and you need hot water for the morning shower. A timer can be installed to switch the electrical element on in time for the morning shower. Once the sun is shinning again, water will be heated by solar.

Electric Geysers typically account for 50 % of the electricity bill in a home of 4 people. Eskom is increasing the ir prices by massive amounts annually.

Retrofitting to your existing geyser is also a possibility.

Most solar water heaters include a backup electrical element in the storage tank.  The electric element is used to heat water in the tank when it falls below a minimum temperature setting. The backup system is normally required in cases where there is constant cloud cover and not enough sunlight to heat the panels. This ensures that the users will always have hot water regardless of the weather conditions. The volume of water held in reserve will determine how long a system can last without electrical support, leading to the conclusion by Van Achterbergh that it is essential to do a site inspection in which the extent of water held in reserve can be determined.

Gas geysers are another option. While saving electricity, they do consume gas.

It is very important that a consultant sizes the solar geyser correctly. A rule of thumb in a household is 50 litres per person per day.A consultan will also advise on the correct system e.g. a heat pump is an outdoor unit and can be noisy for neighbours.
