Air in collectors (No solar gain)
It is possible under certain conditions, such as when the pipe work has been
opened, that air may become trapped in the solar collectors. This will
prevent the circulator from moving water around the collector circuit. The air
will need to be purged from the solar collectors (refer to “Bleeding The Solar
Collectors” on page 9).
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 fit a flow control valve to each
shower outlet to reduce water usage.
Temperature pressure relief valve running
Is the relief valve discharging too much water? (Refer to “Temperature
Pressure Relief Valve Running” on page 23).
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to adjust the
thermostat upwards to gain additional hot water capacity when boosting.
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
(www.rheem.com.au) suggests average sizes that may be needed.
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 gas burner to boost the water temperature on
such occasions.
A lower water temperature may also be noticed in the morning if the gas
boosting has not been used. 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.
