Check the items below before making a service call. You will be charged for attending to any condition or fault
that is not related to manufacture or failure of a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
This can occur with new installations and is normally related to some misunderstandings as to the use of the
booster heating unit.
•
Insufficient sunlight
Insufficient sunlight due to cloudy weather during hotter months or
low solar energy contribution in colder months may mean the booster
heating unit is required to boost more often.
Ensure the booster heating unit is being used as advised. Refer to
"Booster Control"
on page 14.
•
Booster heating unit not operating
Inspect the isolating switch marked "HOT WATER" or "WATER
HEATER" at the switchboard and ensure it is turned on.
Check the timer (if one is installed) and its settings to ensure power
is available to the booster heating unit.
Note: Check the electricity supply to which the unit is connected. If on an Off-Peak or time controlled
electricity supply remember heating hours are restricted.
Check the fuse or circuit breaker marked "HOT WATER" or "WATER HEATER" at the switchboard.
•
Collectors shaded
If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of the solar
collectors will be greatly reduced.
Have the trees trimmed or the solar collectors relocated if the obstruction is permanent or clean the
collector glass.
"Collector Glass"

•
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 to reduce water usage.
•
Relief valve running
Is the relief valve discharging too much water?
"Temperature Pressure Relief Valve or Expansion Control Valve Running"
Refer to
•
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.
"Temperature Adjustment"
Refer to
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 guides in the sales literature and on the Rheem website
sizes that may be needed.
