The best way to heat a pool

Updated February 21, 2017

Pools aren't difficult to heat, but they are expensive to heat. In an age that strives for energy efficiency, the best ways to heat a pool are going to be the cheapest, so it won't put much strain on the environment or your pocketbook. The way in which you heat your pool also depends on how often you use it to the size of the pool itself, and how often the pool is covered affects the pool's heat.

Solar Water Heaters

Solar water heaters are the least expensive to use and most energy efficient and can last 10 to 20 years. There are two types of solar panels--glazed and unglazed, though the glazed can be used year round, while the unglazed cannot. However, the most important aspect of using these panels to heat the pool is the sun. These only work if the sun is out in force when your pool needs to be heated the most.

Gas Heaters

Gas heaters use gas or propane to heat water very quickly and are most efficient for pools that aren't used very often. Unlike other heaters they can keep a pool of water very warm in any type of climate--but come with an expense for doing that. Most gas heaters that are already installed can be replaced with a more energy-efficient model that isn't terribly expensive. Contact a pool specialist about this.

Heat Pump Heaters

These heaters run entirely on electricity and collect heat from outside, making them more efficient than gas heaters. These heaters are best for climates that don't drop below about 10 degrees Celsius and maintain heat quite well if they are used regularly. While heat pump heaters are expensive initially, they'll be cheaper then gas heaters in the long run as they are less expensive to operate and rarely break down, lasting longer.
