TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable this valve allows a small quantity of water to
escape during the heating cycle. However, if it discharges more than a
bucket full of water in 24 hours, there may be another problem.
Continuous dribble
Try gently raising the easing lever on the relief valve for a few seconds
(refer to
“Temperature Pressure Relief Valve”
on page 9). This may
dislodge a small particle of foreign matter and clear the fault. Release
the lever gently.
Steady flows for long periods (often at night)
This may indicate the mains water pressure sometimes rises above
the designed pressure of the water heater. Ask your installing plumber
to fit a pressure limiting valve.
Warning:
Never replace the relief valve with one of a higher pressure rating.
Heavy flows of hot water until the water heater is cold - then stops until water reheats
The water heater
must
be switched off at the isolating switch or switchboard. Phone your nearest
Solahart Dealer to arrange for an inspection.
HIGHER THAN EXPECTED ELECTRICITY BILLS
With the installation of your new air sourced heat pump water heater, maximum electrical energy savings can
be achieved. Should you at any time, feel your electricity account higher than expected, we suggest you
check the following points:
Is the water heater operating in backup heating mode?
If there is a fault condition with the heat pump system, the water heater will default to backup heating
mode to ensure a supply of hot water. If the water is being heated to a temperature of 70°C, this will
indicate there may be a fault with the system.
Refer to
“Heat Pump Is Not Operating”
on page 13.
Is the relief valve running excessively?
Refer to
“Temperature Pressure Relief Valve Running”
on page 14.
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 energy. Replace faulty tap washers,
and have your plumber rectify any leaking pipe work.
Has there been an increase in hot water usage?
An increase in hot water usage will result in an increase in heat pump operation.
Has your water heating tariff rate been increased by your electricity retailer since your previous account?
Is the heat pump water heater on the same tariff as the water heater replaced?
The impact on an electricity account will depend upon the tariff arrangement of the water heater
replaced and where you live. Contact your energy provider for more information on tariff arrangements
and cost comparisons.
Prolonged periods of use when the ambient air temperature is outside of the heat pump‟s operating
range will increase the amount of boosting and increase running costs.
