Choosing a Pool Cover
To extend your swimming season with solar pool heating, every bit of retained warmth counts. Therefore, homeowners sometimes ask: “Is there an ideal pool cover to use in combination with solar heating for maximum heat retention?” The short answer is “Yes!” Let’s look closer at the types of pool covers available and how each interacts with solar heating.
Solid Covers vs. Liquid Covers
Solid covers (like bubble covers or thermal blankets) physically shield the pool from heat loss. These covers trap warmth, limit evaporation, and protect against annoying debris. At night, when the temperature drops, a solid cover dramatically reduces heat escape, preserving the energy gained during the day.
Liquid pool covers, on the other hand, use a thin, invisible layer of alcohol-based liquid that sits on the surface of the water. This barrier slows evaporation and reduces heat loss, offering convenience and ease of use. No reels, no folding — just pour it in, and let it do the job.
Which Cover Works Best with Solar?
For homeowners who want maximum efficiency from their solar pool heating system, a solid cover remains the gold standard. Paired with a solar heating system, solid covers consistently deliver noticeable energy savings and warmer water, especially in cooler climates or during spring and fall. That said, for those prioritizing convenience, a liquid pool cover does provide some benefits, which is better than no cover at all.
