Geothermal Pool Heaters: How Do They Work?

Last Updated on October 17, 2021

One of the best ways to keep your swimming pool water warm during those chilly winter months is by installing and using a geothermal pool heater. Geothermal pools are becoming more and more popular because they reduce the cost of heating your swimming pool while maintaining a constant water temperature.

What Is A Geothermal Pool Heater?

Geothermal pool heaters are a popular option for those who live in colder climates since they require no electricity and little maintenance. Geothermal pool heaters work by transferring energy from the ground to your pool. This is done through an underground loop of piping that transfers the liquid, which will be heated up to a near boiling point, from deep inside the earth to your swimming pool.

This process utilizes water circulation and convection to take advantage of Mother Nature’s constant temperature at or near ground level year-round, meaning that there is no need to rely on fuel sources such as gas or electricity to maintain warm temperatures during cold months.

How Does A Geothermal Pool Heater Work?

Geothermal pool heaters are a relatively new technology and they work differently than traditional gas or electric models. Geothermal systems use the ground as their sole source of energy whereas other heating methods require an outside power source to be run through them before being transferred into your water (either directly or after going through a pump).

The geothermal system underground pipes to draw out that natural heat, which is then used to create hot water for your pool. That means it does not need any external input like electricity or gas!

Types of Geothermal Pool Heaters

There are two main types of geothermal pool heaters:

• Open Loop
• Closed Loop

The type you choose will depend on your needs, the layout of your land, and the amount of money you want to invest.

Open-loop systems don’t require any additional equipment or piping because they use water from an existing pond or well as a heat transfer medium. This is typically not as cost-effective for homeowners who have access to unlimited freshwater sources (like in rural areas). They’re great for warm climates because they can maintain high temperatures all year round without any additional equipment required.

Closed-loop systems use pipes that pump liquid through them using electricity instead of natural gas which can be expensive but provides more even temperatures throughout the pool year-round with no need for supplemental heating when it’s cold outside.

Benefits of Using Geothermal Pool Heaters

You love your pool, and you want to keep it at a comfortable temperature all year long. You don’t want to have to spend a fortune on heating costs since you can choose to install and use geothermal pool heaters.

1. Geothermal energy heats pools without any fuel consumption so you never have to worry about running out of gas or power during cold winter days.
2. It does not produce chlorine byproducts like diesel generators do, which means cleaner air and less chemical build-up over time.
3. Is an environmentally friendly option for keeping pools heated in winter. If you’re looking for a way to keep your pool warm without relying on fossil fuels then geothermal heating systems are worth considering!
4. Since these units are installed underground they don’t require much maintenance.
5. Opting to use geothermal pool heaters can reduce your energy bill by up to 70%.
