Should you at any time, feel your electricity account is too high, we suggest you
check the following points:

•
Is one outlet
shower) using more hot water than
you think? (Refer to
Hot Water" on page 12).
•
Is there a leaking hot water pipe,
dripping hot water tap, etc? Even a
small leak will waste a surprising
quantity of hot water and electricity.
Replace faulty tap washers, and
have your plumber rectify any
leaking pipe work.
•
Consider recent changes to your hot water usage pattern and check if there
has been any increase in tariffs since your previous account.
ELECTRICITY TARIFFS
The electricity tariff to which your water heater is connected will determine the
overall operating cost of the system. It is important you are aware of this tariff,
i.e. Off-Peak (overnight) or time controlled supply, Extended Off-Peak
(overnight and day) or Extended time controlled supply, Domestic / Continuous.
For types of tariffs, refer to
