Its versatile design allows trimming for custom pool shapes, and it folds compactly for easy storage, making it an eco-friendly, cost-effective alternative to traditional pool heaters. ## Description Pool heaters are expensive. Aside from an initial investment of several thousand dollars, you'll also have to regularly shell out money for their operation, repair, and maintenance. Solar blankets present an inexpensive way of keeping your pool water warm. Not only do they cost less upfront, but there are also no ongoing operating expenses to worry about. What's more, they can help minimize pool refills and the use of cleaning products, too! Cut down on your heating, water, and maintenance bills with this Pool Solar Blanket from SunHeater! Review: Helps maintain temperature - Works well. Was surprised by how much heat it holds in, about 2 degrees a night ( during moderate weather) which adds up daily with a pool heater, especially as you first warm the pool. If the sun is out will heat a little faster with cover. Can be folded out of pool and back in, with 1 person. Review: Saves on heat and water - Seems solid and well-made. I use it with a reel and find it saves on both heating and evaporation of water. Yes, it takes some discipline and effort to put it in place but I feel it is worth it, especially if you do not use your pool every day. Regardless of brand, I have found these only last about two years (in FL) before the plastic starts deteriorating. Warranties only cover "defects in workmanship" but not longevity. I have tried the clear version and found little difference - it's mostly a matter of taste. ## Features - Soak Up The Sun - Heat your pool the natural way with this blue solar blanket! When placed on top of the pool with the bubbles facing down, it traps the warmth from the sun and transfers it to the water. - Keep Refills To A Minimum - Using this above ground pool heater can help minimize evaporation by up to 95%. This translates to significant savings since you don't have to add more water as often. - Cut Down Cleaning Time & Costs - Our pool solar cover also helps keep leaves, dirt, and debris at bay. Cut down time spent on skimming and fishing out impurities and save on cleaning products! - Customize According To Your Needs - This 20x40 feet solar pool cover is suitable for rectangular in-ground and above-ground pools. It can also be trimmed to fit square, round, and kidney-shaped pools. - Storage Made Convenient - Despite its large dimensions, this 12 mil pool solar heater can be easily folded down to a compact size. Simply store it away in your shed or on a shelf when it's not in use. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #48,106 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #220 in Pool Safety Covers | | Brand | SunHeater | | Color | Blue | | Customer Reviews | 4.2 out of 5 stars 638 Reviews | | Material | Polyethylene (PE) | | Model Name | Pool Solar Blanket - Trimmable Rectangular Pool Bubble Solar Cover - Heat Transfer Solar Pool Heater | | Size | 20'x40' | | Style | Compact | ## Product Details - **Size:** 20'x40' - **Color:** Blue - **Material:** Polyethylene (PE) - **Brand:** SunHeater - **Style:** Compact ## Images ![SunHeater Pool Solar Blanket - Heavy Duty Rectangular Thermal Cover with Bubbles - Heat Transfer Solar Pool Heater for In-Ground Swimming Pools - Durable 12 Mil Thick Polyethylene - 20' x 40' Feet - Image 1](https://m.media-amazon.com/images/I/71fdslPLX7L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helps maintain temperature *by L***R on January 12, 2026* Works well.

We open our pool late April but the water temp hovers around 70-75 until june at least. I prefer 80+. I had been leaving the blanket on all day and night since the daytime highs are only 70-80 and windy, not ideal swimming weather but sunny. We had a few days near 90 which helped heat it up. Without the blanket we reliably lost 5+ degrees overnight, but now it retains that and has heated up much faster. We’ve been swimming in 80-85 degree water since mid May, even for my daughter’s birthday party which we’ve never been able to do! I was lucky to get the 18x36 for an amazing price, the only reason I gave it a try in the first place. It wasn’t too bad taking it on and off, but we just set up a reel yesterday so now it’s a piece of cake. Love this!! It’s really thick, not flimsy at all. Wish I had gotten one 2 years ago :-) The picture shows this mornings outside temp at 67, and pool temp at 82. In even bought a depth temp sensor to test the temp several feet into the deep end, thinking these blankets just heated the surface of our 16x40 pool….but that’s a consistent temp even 5 feet down. Just saved myself $10k for a pool heater and gas line. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/605957028-sunheater-pool-solar-blanket-heavy-duty-rectangular-thermal-cover-bubbles](https://www.desertcart.de/products/605957028-sunheater-pool-solar-blanket-heavy-duty-rectangular-thermal-cover-bubbles) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-24*
