Whilst electric heaters are not as energy efficient to run as heat pumps, they can be useful to act as backup or booster heaters to heat pumps.

Indoor pools and koi ponds can use an electric heater in conjunction with a heat pump.

In extremely cold weather, the heat pump may not produce sufficient heat to maintain the desired water temperature. An electric heater can be set to turn on under these conditions to boost the water temperature back to the desired level.

3. Sizing

The guide for sizing electric pool heaters is 1.5kw per 1000 gallons of pool or pond water. Or 1.5kw per 4.5m3 of pool water

so for a 20m3 pool, you would need at least a 6.6kw electric heater.

Note that the maximum size of electric heater that can run from a UK 13A socket is 3kw

Our Sunspring heat pumps output up to 10kw of pool heat from only 1.7kw of electricity and so have much lower running costs than electric pool heaters and they can plug into  a standard 13A power socket.

4. Operation

The desired pool temperature can be easily selected on the EVO heater using the panel-mounted thermostat dial. The single or three-phase power is supplied through a top quality Schneider contactor. Safety and equipment protection is provided by the highly reliable flow switch. Over-temperature protection is provided by the thermal cut out (manual reset).
