7 Ways to Heat an Outdoor Pool

Do you ever find yourself wishing you could enjoy pool season a little longer? 

We have some pretty big news for you — you can. While most homeowners are closing their pools down for the season, you can swim freely (without turning into a popsicle). 

Here are seven ways to heat an outdoor pool. Let’s get started, shall we?

1. Solar Covers

Solar covers are designed to absorb heat during the day so your pool can retain warmth during the evenings. A solar cover is a cost-efficient way to extend your pool season and can be used for both in-ground and aboveground pools.

2. Solar Heaters

With solar heaters, you have the option of installing on the roof, against the side of the pool or wherever there are vast amounts of sun. Similar to solar covers, these devices absorb heat and can raise your pool’s temperature 15-20 degrees.

3. Heat Pumps

Heat pumps differ from solar and gas heaters, gathering warm air around the pool, compressing it and using it to heat a cycle of pool water. Heat pumps have the ability to warm the water without sun, using electricity to operate. Having the ability to add 20 degrees to your pool’s temperature, they operate fairly cheaply and have no emissions.

4. Gas Heaters

There are many models out there that work with natural or propane gas. One of the advantages of a gas heater is that you’re guaranteed heat — no matter the elements. The initial price of a gas heater is less than a heat pump, but you may level out the price with what you’ll spend on gas.

5. Solid Pool Blanket

Also known as a “safety” blanket, a solid pool blanket is a great heat retention device. It uses a series of tracks and a motor to  roll heavy duty vinyl over the surface of your pool. 

Not only is it able to cover the entire area of your pool, but is able to hold the weight of a child — a valued safety feature in homes with small children.

6. Floating Blanket

Less expensive than a solid pool blanket, a floating blanket is a thin vinyl sheet featuring small bubbles of area for heat retention. It’s free floating but tends to wrap around anything in the pool. So if you have pets or small children, please be watchful!

7. Liquid Blanket

Another way you can heat an outdoor pool is by using liquid blanket. Easy to use, non-toxic and inexpensive, you simply pour into the water. Liquid blanket creates a thick layer on the surface of the water, slowing down evaporation. 

Its performance is affected by wind speed or anything else that breaks the surface. Though it’s the easiest solution, it’s also the least effective way to retain heat — but overall, better than doing nothing.
