Failure of Electric Heater |
The heaters are usually on ‘economy’ electrical supply, operated by a time clock. A power cut may alter the time for switching on the unit.
If the filter requires backwashing, only a small volume of water may pass through the heater, and the built-in safety device will trip the excess temperature switch.
The heater will not operate if the thermostat is set at a lower temperature than the pool water. |
Adjust to correct amount of water.
Backwash filter.
Re-light pilot light.
Set thermostat to the correct temperature. |
Gas Heater |
Insufficient amount of water passing through the heater will not operate the pressure switch.
Filter requires backwashing.
Pilot light, if fitted, may have gone out.
The heater will not operate if the thermostat is set at a lower temperature than the pool water. |
Adjust to correct amount of water.
Backwash filter.
Re-light pilot light.
Set thermostat to the correct temperature. |
Oil Heater |
Check the oil level in the tank. This may seem obvious, but manu calls are due to no oil. |
Check and fill the tank oil if necessary.
Check the temperature controller. Adjust if necessary. Check reset button on the burner. |
Heat Exchanger |
Check that the boiler supplying heat is operating.
Check for airlock in the heat exchanger.
Check that the secondary circulation pump is operating.
Check the temperature controller. |
Consult your maintenance company
Adjust if necessary. |
Heat Pump |
Clean the air intake at regular intervals.
If there is sufficient water flow through the heat pump it will cycle on and off. |
Always make sure that nothing is restricting the air outlet to ensure maximum airflow through the heat pump.
The filter should be backwashed and pump strainer and skimmer baskets cleaned. |
Solar Heating |
An adequate flow of pool water through the solar panels is necessary to ensure efficient operation. If the surface of the panel i not cool to touch when operating in bright sunshine, this indicates inadequate flow, and the cause should be identified. |
Check water flow to identify causes.
The panels may not work if the air/water temperature differentials is too great.
No regular maintenance is required, other than washing off any dirt accumulating on the panels. |
