There are two types of electric heaters for inground swimming pools: basic electric and heat pump. Electric pool heaters work by heating a coil that heats the water in the pool. However, keep in mind that these inground heaters take longer to heat the water and are ideally used in climates above 40 degrees Fahrenheit.

Heat pump electric pool heaters are an effective way to heat the pool with electricity, and they don’t take as long as a coil system. Inground heat pumps work by transferring warm air to the water. The heat pump compressor heats the air and transfers the heat to the water using a heat exchanger. This is an efficient use of electricity because the heat is transferred, not generated. Heat pumps are a standard choice among pool owners who live in warmer climates, since they do rely on the temperature outside to heat the pool water. All of the heaters for inground pools at Pool Express are from top-rated brands, including Laars, Raypak and Hayward.
