General information about Solar Water Heating
IS SOLAR WATER HEATING?
Solar water heating is a system for heating water using energy from the sun.
Solar energy is collected by a panel/collector, which is then connected by pipes
to a hot water storage device such as a hot water cylinder.
Solar water heaters can help save water heating costs by reducing the amount of
gas and electricity needs to heat water. By using sunlight to heat water instead
of combustible sources or follies fuel-produced electricity, fewer pollutants
are being introduced into the environment. Solar energy is not affected by the
current shortage of electricity and does not stop providing hot water during
The electrical geyser uses on average between 30 – 50 % of your household’s
monthly electricity bill. Replacing your conventional geyser with a solar
powered system will reduce that percentage of your electricity consumption by up
The ideal temperature of your geyser or tank is between 55 and 60 ˚C. Most solar
systems heat the water to between 60 – 80 ˚C, but some can heat much higher than
that. You need to be aware of over-performing systems so that you are not
scalded by the hot water.
Solar water tanks are better insulated than electrical geysers and can keep
water hot for a longer period of time. This ensures that there is always a tank
full of hot water in the evenings/mornings – provided the tank size is correct
and the users do some planning.
A solar system has a lifespan of 5 to 20 years depending on the system and the
maintenance on the system.
Soon all new buildings will have to be energy efficient by law. The legislation
for new buildings has already been gazette.
