Options for Heating Your Pool 

All methods of heating pools and spas introduce heat into the water. This can be done in several ways, but the most common options utilize heaters or heat pumps:

Gas Heater
Gas heaters are the most popular equipment for heating pools. They are ideal for quickly and efficiently heating any pool.

Heat Pump 
Heat pumps work by transferring heat from the environment to the pool water using electricity. They have a higher initial cost than gas heaters, but are more energy efficient in the long run. Heat pumps are a good choice for maintaining a pool at a set temperature, but they are sensitive to climate variability.
