Pool heaters work by using gas and electricity to heat coils and your pump moves the water over these coils thereby heating the pool water. Some pool heaters utilize heat pumps which only use electricity and the heat from the sun and transferring the heat to the pool. If your heater just isn’t working, J Pool Service technicians will inspect your heater to determine if a repair is possible without replacement. If you need a replacement or you don’t have a heater at all and want one for your pool, call us today for consultation on pool heater options and installation!
