Thermotec Mini Heat Pump UK Plug and Play Pool Heater for Above Ground Pools. Slash the cost of heating your pool using theThermotec Mini heat pump rather than an electric heater. If you compare this with an electric pool heater, a 4kw electric pool heater would use 4kw of electricity, and a 5kw electric pool heater would use 5kw of electricity, much more expensive to run.
