Are you thinking of installing a solar pool water heater?

Is this really a better choice than an electrical one?

What are some benefits of using a solar water heater for pool purposes?

Here are a few to keep in mind:

  • Electric water heaters for swimming pools are very expensive to operate. When you have a solar heater instead, you can cut back drastically on the cost of heating your pool.
  • Electric heaters take up a lot of space in your yard. However, most solar heaters can be mounted on the roof and don’t take up any room, making them efficient in more than one way.
  • Electric heaters have more components that are capable of breaking than solar heaters do. Although you’ll still need to keep up with routine maintenance, you’re less likely to encounter problems with a solar heater.

When you run a swimming pool, keeping it heated can be an unexpected challenge. However, by using a solar water heater, you can take care of your pool’s heat without having to give it a second thought.

In this article, we’ll show you five of the best solar water heaters on the market for use with swimming pools. Take your time looking through this information to figure out which one is right for you and your pool setup.

Did you find a good heater for your swimming pool? Choosing to use a solar heater is a great way to save money and make heating your pool even easier than ever before. But picking the right heater can take a little time and consideration. It’s important to choose one that can manage the volume of water your pool contains, as well as one that can run as continually as you need it to.

Of course, there may be other features and qualities you’re looking for in a heater, especially when trying to ensure it will work with your pool. How do you know a heater will work for your pool? What are some ways to check for compatibility?

  • If the heater must be mounted to the side of your pool instead of on the roof, choose one that works with your pool’s shape and size. If you can’t find one that works like this, you may need to look at roof-mounted heaters instead.
  • Check the manufacturer’s recommendation on any heater you’re considering to see if it works with the size and volume of your swimming pool. Some are only intended for use with above-ground or inflatable pools, while others can be used with in-ground pools.
  • Pick a solar heater that you can assemble and install on your own if you choose to do so. Otherwise, pick one that can be installed by professionals in your area. If you’re unsure, reach out to the professionals first to ask for recommendations.
  • Choose a heater that can be hooked up easily to the water supply for your pool. Understand that different pipes have different connector needs, and that some heaters that may be “near-universal” are still not completely universal.
  • Finally, don’t forget to pick a heater that works for your budget! There are plenty of low-cost, budget-friendly water heaters on the market, but there are also high-end heaters that cost more.

Take your time considering the heaters available and bring home the right one for the job!
