450 litres of water it is possible that
there will be certain times of the
day where there is insufcient hot
water. It is also advisable to inspect
tap washers etc. for leakage and
replace if necessary.
• Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
• Replace faulty tap washers and
have your plumber rectify any
leaking pipe work.
High Electricity Bills
Low Solar Energy Input
If there have been prolonged periods
of cloudy weather, or winter is
approaching, it may be necessary for
the electric booster element to run for
longer periods, and this will increase
energy bills.
Solar Collector Shading
Often trees or other buildings can shade
the collectors, or there can be dirt build
up on the glass cover. Trees should
be cut back if possible, or the system
relocated if removal of the shading is
not possible, in the present location. If
the glass is dirty, this should be cleaned
with any normal domestic glass cleaner
– recommended to be done by an
authorised tradesperson.
Condensation in Collectors
In winter, or in times of heavy rain,
water vapour may form in the warm and
humid collectors, and then condense on
the inside surface of the cold glass.
As collectors are insulated for optimum
performance and have minimal internal
airow, condensation that has formed
during these times takes a longer time
to disperse but will do so when enough
direct sunlight has come in contact with
the collectors. The warmer the sunlight,
the faster it will disperse.
Condensation in the collectors does not
affect the system’s performance.
