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 7).
Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Carefully review the family’s hot water usage. As you have installed an energy
saving appliance, energy saving must also be practised in the home. Adjust your
water usage pattern to take advantage of maximum solar gains. Still have
enjoyable showers, but restrict the amount of hot water used by simply fitting an
inexpensive flow control valve to your shower rose.
Temperature and pressure relief valve running
Is the relief valve discharging too much water? (Refer to “Temperature and
Pressure Relief Valve Running” on page 16).
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to adjust (Optima
models) or have your electrician adjust (Rheemglas models) the thermostat
upwards to gain additional hot water capacity when boosting.
Water heater size
Do you have the correct size water heater for your requirements? The sizing
guides in the sales literature and on the Rheem website (
www.rheem.com.au
)
suggest 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 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.
