Residential Pool Heaters & Heat Pumps

Residential Swimming Pool Heaters, Heat Pumps & Spa Heaters

The perfect pool is neither too hot nor too cold. A comfortable and enjoyable 77-85 degrees provides the optimal experience. However, depending on where you live and your climate, keeping a continuous temperature throughout the summer or even all year requires heating your pool.

A pool heater or a pool heat pump are the most common heating solutions that allow you to extend your swimming season. Both enable energy-efficient heating for every budget, and there are various factors to consider when determining the best heating solution for your pool.

Are pool heaters gas or electric?

Pool heaters can be either gas or electric, depending on the model and type of swimming pool.

Gas heaters use natural gas or propane, while electric heaters use standard electricity. Gas heaters are typically more expensive to install but may provide cost savings in the long run as they are generally more efficient than electric models. Additionally, gas heaters have the advantage of being able to provide a faster heating time and higher temperatures than an electric heater can manage. 

Electric pool heaters, however, tend to be less expensive upfront and require less maintenance over time. They also offer more precise temperature control and are quieter than their gas counterparts. They could be more costly to run long term depending on your local cost of electricity.
