Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when
showering. Carefully review the family’s hot water usage. As you have
installed an energy saving appliance, energy saving should also be
practised in the home. Adjust your water usage pattern to take advantage of
maximum solar gains.
Have your plumber install a flow control valve to each shower outlet, basin
and sink to reduce water usage.

Temperature pressure relief valve running
Is the relief valve discharging too much water? (Refer to
Pressure Relief Valve Running”
•
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to have your
electrician adjust the thermostat upwards to gain additional hot water
capacity when boosting. Refer to
on page 5.
Warning: Hotter water increases the risk of scald injury.

Water heater size
Do you have the correct size water heater for your requirements? The sizing
guide in the sales literature and on the Rheem website

NO WATER FROM THE HOT TAP
No flow of water from the hot tap may indicate a restriction in or failure of the
cold water supply to the water heater. Check for water flow at other taps and
that the cold water isolation valve
WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage or low solar energy gain the
water temperature may be lower than normally expected. You will need to
carefully plan your use of the booster heating unit to boost the water
temperature on such occasions.
A lower water temperature may also be noticed in the morning when the
booster heating unit has not been switched on overnight. This in particular may
be experienced during periods of low solar energy gain, or if there has been
heavy hot water usage the previous night.
