you have a 250 litre storage tank
and you are using 390 litres of
water, it is possible that there will be
certain times of the day where there
is insufficient hot water. It is also
advisable to inspect tap washers etc.
for leakage and replace if necessary.
High Electricity Bills
• Is the Pressure & Temperature Relief
Valve discharging too much water?
• Is one outlet (e.g. the shower) using
more hot water than you think?
• 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.
The Unit Does Not Run
Check that the power supply is turned
on and that the house circuit breakers or
fuses are on and operational.
