solutions. The timer is also needed to qualify
for an Eskom subsidy. You want to use your solar energy
collector as far as possible to heat water during the day
but you also want to make sure you have hot water whenever
you need it. The timer will for instance make the back-up
element kick in, in the early evening if the thermostat
senses a last bit of heating is necessary. But it shouldnt
happen too often, depending on weather conditions.
Eskom says people should consider bathing at night to make
use of the free energy collected during the day.
2. How a Solar geyser work?
With the continued power crisis
and the increase in electricity rates, solar water heating
is the best solution for South Africa households. A kwikot
solar geyser can save up to 90% on your water heating
costs. With a Kwikot, households will have enough hot
water, even when the power is out.
3. How long should a Solar water geyser
Eskom says the expected life-span
of a solar water heater is 10-20 years, depending on various
factors. Some systems have a 10 year guarantee and a life
expectancy of about 20 years. Etzinger says. The Sustainable
Energy Society of Southern Africa says they know flat-plate
systems that are still working after 27 years.
4. How hot is the water?
Most quality solar water heaters
will hear water between 55 and 65 degrees Celcius, Eskom
says. On a average cloudless day of solar radiation it
will be 60 degrees plus, Ezinger says.
5. What happens when the sun doesn't
Solar water heaters tanks are
much better insulated than those of electric geysers and
can therefore keep water hot longer, Eskom says. For occasions
when the water temperature falls below the desired level
most solar water heaters have a back-up electric element.
Supplier Cobus Roux says technological advances have also
made modern systems more effective, some can generate
enough hear in overcast conditions. If solar water heaters
work in London theyll definitely work in S.A. Etzinger
says. SA has some of the highest solar radiation levels
in the world.
6. How long does it take to install?
Our dedicated installation teams
can install a Kwikot solar heater in less than a day.
