Swimming pools & Hot tubs

Heated swimming pools are a necessity in colder regions across the world. You can choose from two main options to resolve the problem of too cold water in your swimming pool. 

​

The cheaper of the two choices is a solar blanket. It looks essentially like a huge bubble wrap – a sheet with tiny bubbles of trapped air, big enough to cover the surface of the swinging pool. A solar blanket captures the sun’s energy during the daytime to raise the temperature of water in the pool and retain the heat at night. 

​

The downside of using a solar blanket is that it needs to be removed when you want to swim and spread out again after use. If you want to avoid this hassle, you can try the more expensive choice of installing a solar water heater to heat the pool water. 

​

A solar water heater has solar heating panels mounted on rooftops to capture the sun’s heat. The heat is conveyed to the pool water using a series of conduits circulating the water from the pool. As the pool water loses heat, it is circulated through these pipes to the solar heating panels, where they get heated up. The water is circulated back to the pool which raises the overall temperature of the swimming pool.

​

With costs between $2,500 and $4,000 and a payback period of one to seven years, the U.S. Department of Energy says that “solar pool heating is the most cost-effective use of solar energy in many climates.”
