  • These pool heaters have an output of 2kw or 3kw.

  • 2 or 3kw Stainless Steel heating element
  • Ideal for above ground pools up to 12′ diameter

  • Digital Display

3. They are ideal for:

  • Swim Spas

  • etc

As it is an electric heater, it consumes 2/3kw of electricity to produce 2/3kw of pool heat.

Specifically designed to ensure maximum safety, reliability and efficiency, the Pro-line pool heater is user-friendly and offers ‘plug & play’ installation. The thermostat is of the highest quality and accurate to 0.1 degree, it gives you control over the desired pool temperature, while the thermal safety cut-out avoids over-heating.

The element must be fully submersed in the water either in the pond/pool itself or in the filter somewhere.




4. Sizing

The guide for sizing electric pool heaters is 1.5kw per 1000 gallons of pool 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

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

5. Alternative Pool Heater

A heat pump will offer much lower running costs. If you are interested in a pool heat pump for your above ground pool, please see our Sunspring range of pool heat pumps.
