Electric pool heaters have much higher running costs than pool heat pumps, however they can be useful as backup heaters to a heat pump for all year round use
They can also be used for above ground pools, but we would always recommend using a heat pump where possible
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
