With most of the country in Winter’s Icy grip, we are fielding more questions about how our replacement spa covers handle winter. After 30 years of custom building hot tub covers this is nothing new.
Because our design rests right on the spa water surface it looks and acts different from the hot tub cover that came with your spa. Which is good because the typical rigid foam cover does a lousy job of keeping your water warm.
Before I go into why our spa cover is so much better let me explain what we found wrong with the rigid foam covers so that you can better understand the need for such a drastically different kind of hot tub cover.
Once a rigid foam cover has been on your spa for more than six months, it has begun to take on moisture. The moisture does not come from rain or melting snow as you may have been told, but from steam rising from the warm spa water.
Steam molecules are extremely small and as the rise they find their way into the cracks and crevices in the beaded foam boards spanning the water. Once the steam cools it condenses back into liquid that then becomes trapped in the foam.
Eventually, you would notice the weight of your hot tub cover starting to increase due to this accumulation of moisture saturating the foam. It happens slowly over time so most people don’t notice the added weight at first.
The added weight from water saturating the cover is not the real problem though. What happens when the outside temperatures drop below freezing is that the moisture trapped in the spa cover freezes.
Once the water in the hot tub cover is frozen it actually works like a radiator cooling your spa water as the steam hits the bottom of the icy cover and condenses the cold water drops back into the spa. So your hot tub has to work harder to keep the spa water warm.
What fools some spa owners in to thinking their saturated foam cover is insulating really well is that snow won’t melt off their cover. Like a frozen pond, snow doesn’t melt off a block of ice.
Knowing the challenges of every foam filled hot tub cover we went in a totally different direction with the SpaCap hot tub cover. Because it uses air to insulate rather than foam the SpaCap doesn’t saturate or break like a rigid foam cover does.
And since the bottom of the hot tub cover rests right on the water, the insulation starts right at the water surface and does not allow for nearly as much heat loss due to evaporation and condensation as happens with foam filled covers.
As a bonus most spa owners find that their water and chemical levels stay more consistent.
