Three Ways to Heat Your Pool

If you want to enjoy swimming in your pool even during the colder seasons, you might want to think about installing a pool heater. You can find different types, each offering its own benefits. One of the important factors to consider, however, is energy efficiency. The Department of Energy recommends these three types of pool heaters for their energy saving properties.


The most popular system, gas-fired pool heaters are fueled by either natural gas or propane. They heat water faster than a heat pump or a solar heater, at a rate of 1 to 1.25 degrees Fahrenheit per hour. However, the heating produced by gas pool heaters lasts only for a short time, making this equipment appropriate only for pools that are not used frequently.

Heat Pumps

Heat pumps don’t generate heat; instead, they recycle heat from the environment and distribute it to the pool. As pool water passes through the unit, it gets heated by the recycled heat. Heat pumps don’t emit toxic gases; however, they work most efficiently during warmer weather when there is a good amount of heat to absorb from the environment.

Solar Heating

Solar heating systems involve wiring solar panels to a conventional pool heater, providing the heat instead of fossil fuel. With solar technology constantly evolving, today’s solar panels can operate efficiently even when the sun is not shining. However, compared to the two other options given here, solar heating generally requires a higher investment cost.
