Frequently Asked Questions

Can I connect the solar water heating system
to my existing geyser?
Yes. The Vesuvius system connects to your
existing geyser with an uncomplicated conversion.
However, If your geyser is older than five years, we
would suggest installing a new geyser. The new
solar-designed geysers are made for solar water
heating systems and are very well insulated to
prevent heat loss.

How much of a saving can I expect when I
install a Vesuvius solar water heating system?
You can expect a saving of up to forty percent on
your current electricity bill.

What happens on overcast and cold days?
The efficiency of the Vesuvius system means that
your water will still be heated on overcast days,
but perhaps not to the same high temperatures
that you will reach on a day of full sun. However,
your geyser will remain connected to your
electricity supply, so that if you do not reach a
high enough temperature in your geyser, the water
will be heated by electricity for the final few
degrees. You will still be saving on electricity as
the majority of the heating will by done by the sun.

What happens if one of the solar tubes on the
roof is broken?
In the unlikely event of one or more of the solar
tubes breaking, they can be quickly and easily
replaced without any interruption to the functioning
of the system, as there is no water running in the
tubes. The tubes are manufactured from 2.1mm
thick glass which is resistant to hail up to 35mm.
