How much will this raise my pool temperature?

Expect roughly 3 to 7°F in full sun with good flow, depending on pool size, air temperature and how much of the day the mats see direct sun. It will not match a gas heater.

Is 100 sq ft enough for my pool?

As a rule, solar collectors should cover 50 to 100% of the pool's surface area. Two mats suit small aboveground pools; a typical inground pool needs several more panels.

Can I use it with an aboveground pool?

Yes. It works with aboveground and inground pools and connects to the existing pump return line with standard hose fittings.

Does it need its own pump?

No. It runs off your pool pump, but you will need to run the pump during sunny hours, which adds some electricity use.

What happens in winter?

Drain the mats and store them before freezing weather. Trapped water can split the PE panels.

Two 2.5 x 20 ft black PE mats. Check the listing for hose adapters, clamps and a bypass valve, since these are often sold separately.

Our take on the 2 Pieces 20 Feet Weatherproof Solar Swimming Pool Heating System

A two-panel solar pool heating system: each mat is 2.5 ft wide by 20 ft long, made of black all-weather PE, and together they cover about 100 sq ft of collector area. Pool water is pumped through the mats and warmed by the sun, which extends the swimming season without gas or electricity. It fits aboveground and inground pools. The best new price is $174.99 at Macy's as of November 7, 2026, with only one store listing it new, so there is no meaningful price history to compare against.

Pros

No fuel or electricity cost to run; the pool pump does the work
About 100 sq ft of collector area from two 2.5 x 20 ft mats
All-weather PE construction is light and rolls up for off-season storage
Works with aboveground and inground pools
Simple plumbing ties into the existing pump return line

Cons

Output depends entirely on sun and air temperature; weak on cloudy days
100 sq ft is small for most inground pools, which usually want 50-100% of pool surface area
Adds pump run time, so electricity savings are partial
Mats need a sunny, unobstructed spot and freeze protection in cold climates
No controller, valves or mounting hardware described beyond the mats
