EXPANSION CONTROL VALVE RUNNING

If an expansion control valve is fitted in the cold water line to the water heater

(refer to page 23) it may d

ischarge a small quantity of water instead of the

temperature pressure relief valve on the water heater. The benefit is that

energy is conserved as the discharged water is cooler.

HIGH ELECTRICITY BILLS

Should you at any time, feel your electricity account is too high, we suggest you

check the follo

wing points:

• Is the relief valve running

excessively? (Refer to

“Temperature Pressure Relief

Valve Run

ning” on page 13).

• Is one outlet (especially the

shower) using more hot water than

you think? (Refer to “Not Enough

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 aw

are 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 “Single Element Model” on page 8 and “Twin

Element Mode

l” on page 9.
