What to check for during service calls
If there is not enough hot water we recommend that the following points are considered as part of the
service call. The most obvious reasons for a lack of hot water could be one of the following:
Low solar energy input
If there have been prolonged periods of cloud or winter is approaching, it may be necessary to
reconsider the permitted boosting time for time-clock controlled systems or to turn on the booster
for systems with a booster isolation switch.
Solar collector shading
Often trees or other buildings can shade the solar collectors or there can be a dirt build-up on the
glass cover. Trees should be cut back if possible or the system relocated if removal of the shading
is not possible in the present location. If the glass is dirty this should be cleaned with standard
domestic glass cleaner. If rainwater collection occurs from the same roof on which the solar water
heater is located, do not use chemical cleaning agents to clean the collectors. Any spillage of these
onto the roof could cause contamination of water in the rainwater tank.
Booster system not operating
For electric systems the fuse or circuit breaker supplying the AES System should be checked. If the
time clock (where fitted) and the fuse or circuit breaker are operational and the water is cold, you can
turn the booster isolator on and off to see if the electricity meter speed changes. If there is no change
in speed, it indicates there may be a booster problem. Contact your authorised Conergy dealer or
installation service provider as soon as possible.
For gas systems the gas and electric supplies to the gas heater should be checked to ensure they
are both on. If water temperature from the gas heater is below 60 °C and both supplies are on and
the gas heater does not ignite there may be a problem. Contact your authorised Conergy dealer or
installation service provider as soon as possible.
Excessive water discharge from the valves?
If there is a discharge of more than 10 litres per day from any of the systems valves, it indicates there
may be a problem with the valve or an increased water supply pressure. Contact your authorised
Conergy dealer or installation service provider as soon as possible.
Using more hot water than anticipated?
Often the hot water usage of showers, washing machines and dishwashers is underestimated by
the customer. Review these appliances to determine if the daily usage is greater than the storage
volume of the water heater. Depending on the model, our TS system tanks contain 180 or 300 litres
of hot water therefore if the customer’s usage is greater than 300 litres within a short period of time,
there may be periods where the water temperature is slightly lower than normal. It is also advisable
to inspect hot water tap washers etc. for leakage and replace if necessary.
