It Pays to Cover Your Pool with a RaeGuard™ Heat Retention Bubble Cover
If you’re looking for a way to keep your pool warmer for longer and cut down on heating costs, a high-performance heat retention pool cover like RaeGuard™ is a game-changer. Designed specifically to lock in heat and prevent evaporation, RaeGuard™ is perfect for pools that don’t get much direct sunlight—whether it’s an indoor pool, a shaded backyard oasis, or a commercial pool that’s in use and uncovered throughout the day.

How Much Can You Save with a RaeGuard™ Pool Cover?
Leaving your pool uncovered is like leaving the heating on with the windows open—it’s just wasting energy! In fact, a recent study at our own testing facility has shown that over its 8-year lifespan, an 8m x 4m RaeGuard™ cover can save you over £3,000 in heating costs compared to an uncovered pool. That means this cover pays for itself 7.5 times over.
A More Sustainable Way to Keep Your Pool Warm
Not only does a RaeGuard™ heat retention pool cover save you money, but it’s also beneficial for the environment. By reducing the amount of energy needed to heat your pool, it has the potential to be carbon negative over its lifetime. That means for every square meter of pool surface covered, you could prevent 38kg of CO2 emissions from entering the atmosphere – for a typical 8m x 4m pool, that’s the equivalent emissions of a passenger on a transatlantic flight.
Plus, like all GeoBubble™ covers, RaeGuard™ significantly reduces evaporation—saving 25,000 litres of water per square meter. For an 8m x 4m pool, that’s enough water to fill 21 domestic pools over the life of the cover! Explore our high-performance Guard products to see how RaeGuard™ compares to other options.

Why Choose RaeGuard™ Over Traditional Heat Retention Covers?
Traditional heat retention covers, like thick 5mm foam, can be bulky, expensive, and prone to waterlogging. RaeGuard™ offers 90% of the heat retention of these covers, but in a lightweight, long-lasting design that’s easy to handle. It’s also a great option for hot tubs and spas, adding an extra layer of insulation when used alongside a conventional hard-top cover.

“We have found that the pool is much warmer in the mornings than it ever was before. The condensation we used to get on our walls and windows is a thing of the past, and we are paying noticeably less on our heating bills.
The Heat Retention Pool Cover looks great and we are really happy with how well it is working for us”

“Our new Heat Retention Pool Cover has been a massive improvement on our old, waterlogged foam cover. It is so much easier to take off and on, which we do multiple times a day. We have found that the pool is holding its temperature much better than before, and there is no noticeable heat loss overnight.
We have also noticed we are using up far less chlorine than previously, the clarity of the water has improved, and we are dedicating a lot less time to keeping the pool clean.”
Ross, Estate Manager – Dulwich Prep School Cranbrook, UK
