7 Cheap Ways to Heat Your Pool

We're Here to Help

The best part of summer is jumping into a refreshing pool on a sweltering hot day. As summer days give way to fall, the heat starts to lessen, but there are still plenty of swimming days ahead, especially in Texas. Keep your pool open for a few more months, and discover the best ways to heat your pool without breaking the bank.

As the autumn leaves fall, along with the temperatures, swimming in your backyard pool is an excellent source of exercise and relaxation. It’s an inviting place to gather with friends and family for back-to-school parties and barbecues. But, heating your pool can be expensive, with an average cost of $120 to $850 a month, depending on the source of heat (such as heat pump, propane, or gas) and the size of your pool. Read more for ways to heat your pool for less during the off-season, so you can swim without worrying about the cost. 


One of the most cost-effective methods for retaining heat in a swimming pool is installing a solar cover, keeping water up to 10 degrees warmer than with only a heater. The root cause of heat loss in a pool is evaporation. Heat rises, causing warm water to rise off the top of the pool and then evaporate into the air. Most heat loss occurs during the day when the pool is exposed to the sun. A solar cover acts as a protective lid and is designed to absorb solar heat and reduce evaporation. Plus, a solar cover reduces debris getting into the pool, conserves water, and lessens chemical consumption. Explore these reviews on the Best Solar Pool Covers 2024.  


Solar sun rings work in a similar way to solar covers. Instead of covering the entire pool, however, solar sun rings are five-foot inflatable vinyl circles that can hook together and float on your pool to absorb heat from the sun and prevent evaporation. Solar rings can be more versatile, flexible, and don’t need to fit perfectly over the surface of a pool like solar covers. They also can be stored and stacked with ease, though they may not achieve entire pool coverage like a solar cover. 


Just like solar sun rings or a solar cover, a liquid solar pool cover works to combat evaporation and prevent heat loss in your pool. The liquid solar pool cover, as its name suggests, is a type of liquid that is poured into a pool which creates an invisible liquid barrier that sits on top of the water. This liquid layer reduces evaporation, which decreases heat loss. The liquid is perfectly safe to swim in, is biodegradable, and does not contain any harmful chemicals. If your pool is in a windy location, this might not be the most effective method, as the wind can break the liquid seal.


A windproof pool enclosure is the best method to keep your pool warm if you live in a windy area. The wind disrupts the surface area of the pool which allows for warm water to escape. Windproof enclosures protect against windy intrusion and help maintain water temperatures. A bonus is that windproof pool enclosures make the pool accessible in any weather, rain or shine. The cost depends on the size of the pool and the materials used to build the enclosure.


This may be one of the most simple but clever ways to heat your pool. Simply purchase a black garden hose and connect it to the outside water spigot. Ensure your hose is in direct sunlight, wrapped in a coil shape to maximize its surface area (while still reaching your spigot and pool). Utilize the sunny Texas climate and take advantage of solar energy to heat your hose. The warm hose will increase the water temperature as you refill your pool. 


A pool heat pump is a valuable investment. Pool heat pumps draw in warm air from the atmosphere and use that air to heat the pool through a low-energy process. Heat your pool fast with this process which transfers heat from the atmosphere into the pool water. Additionally, a pool heat pump relies entirely on temperature, not solar energy. Compared to propane and gas, heat pumps are a cost-effective, efficient way to maintain a comfortable pool temperature in cooler months.


Although this method may be a slightly bigger investment up front, you’ll find this most effective when heating your pool for less year after year. Combine a solar cover or solar rings with a pool heat pump to heat your pool fast and maintain a comfortable temperature. The pool pump will keep the water temperatures warm on cloudy days and nights, while the solar heater takes advantage of sunny days. Combined, you will have a warm pool for little cost!
