Electrical hot water geysers are
responsible for the biggest portion of your electricity bill.
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 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.
is very important that a consultant
sizes the solar geyser correctly. A rule of thumb in a household is
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
