Best Ways to Keep Your Pool Heated

There are many easy and cost-effective ways to keep your pool heated so that you can enjoy it all year long! Take a dip when the weather gets colder by keeping your pool warm.

How to keep your pool heated in colder months. 

Pool owners, wouldn’t it be nice to get more use out of your backyard oasis? Most people close down their pools after the summer months. If you keep your pool warm, you can enjoy it well past the hot days. And, who’s stopping you from opening it up even earlier in the spring? A heated pool makes for a happy pool owner.

The best ways to keep your pool heated include using solar energy, insulation, a pool enclosure, the black hose trick, a heat pump, a heat exchanger, and a pool cover. When you keep your pool at an even temperature, your swimming season will last longer. Some heating systems will allow you to use your pool all year!

If your head starts spinning when you think about the cost and upkeep of heating a pool, don’t panic. There are several different ways to keep your pool warm that won’t cost an arm and a leg. The solutions below are effective and easy too.

Solar Energy

Solar energy is an environmentally friendly way to keep your pool heated. There are a few different ways that you can harness the power of the sun:

  • Solar panels: take heat from the sun and converts it to energy to be used with a water heater.
  • Solar mats: works similarly to solar panels, but the pool water is warmed by the mats in order to heat it. Ideal for smaller pools that don’t use much water.
  • Liquid solar pool cover: a type of non-toxic liquid that keeps pool water from evaporating. Less evaporation means less heat loss.


In the same way you insulate your house to keep it warm, use insulation to keep your pool heated! This method of keeping your pool warm works best if you haven’t installed your pool yet, especially if it is in-ground.

During the construction phase, you’re going to want to make sure that your pool is surrounded by insulation on the sides as well as the bottom. The insulation acts as an added layer between your pool and the cold.

Pool Enclosure

A pool enclosure will protect your pool from the wind and will prevent the water from evaporating. A lot of your pool’s heat is lost through evaporation. While this method may not add heat into the water, it will keep it from escaping.

You can also use a protective pool enclosure to take advantage of your pool, even when it’s raining!

The Black Hose Trick

Veteran pool owners will recognize this approach! Head to your local hardware store and pick up 100-150 feet of black (or dark-colored) hose. Place the hose in a coil near your pool where it will get the most sunlight. Attach one end of the hose to your water supply and place the other end in your pool. The water will run through the heated hose and then go back into the pool.

Be aware that, like using solar, the black hose trick only works on a sunny day.

Heat Pump

A heat pump uses electricity to take in heat from the air and then pump it back into your pool in order to heat it. This method relies on the temperature of the air outside. As long as temps stay above 50 degrees F, a heat pump is an efficient way to keep your pool warm!

If you want to use your pool in cooler months like April or October, a heat pump is ideal!

Heat Exchanger

A heat exchanger is your best bet if you want to keep your pool toasty in even the coldest months. Heat exchangers are able to heat a pool in just one day. The best part about using a heat exchanger to keep your pool warm is that it doesn’t rely on the sun. You can use it on overcast days as well.

Pool Cover

The simplest way to keep your pool heated is to use a pool cover. There are different models available (some use solar), but the concept is the same. When the water in your pool becomes warm from the sun, the hot water floats to the top, then evaporates. A pool cover keeps all of that warm water inside.
