Why Hot Tub Covers Get Saturated

Every traditional foam filled hot tub cover gets saturated and heavy. The how and why may come as a surprise. It really has nothing to do with rain so it doesn’t matter how steep the taper is, that cover will still get heavy. If it had been rain which has been making spa covers heavy then placing a roof over the spa would stop the cover from getting heavy.
Moisture getting trapped in the foam is the thing that eventually makes a hot tub cover too heavy to lift. However if it’s not the rain, how can the water get in there? The answer is steam that are caused by the warm spa water. When water becomes steam this is actually a smaller sized molecule than a drop of water.
Steam can get right into a much smaller area, like say the spaces inside the foam. Once it cools back down and turns into water again, it’s trapped stuck inside the foam. Once trapped in the foam the water won’t drain out so a fancy drain hole won’t help. The only way the water can get back out of the foam would be to evaporate. In order to evaporate, the spa cover has got to be removed from the supply of steam (the hot tub) and placed inside a dry, well ventilated area.
The issue has nothing to do with how well the cover is maintained or the volume of vinyl protector is rubbed on it. The reality is it’s the foam itself. The kind of foam used in hot tub covers is needed to be used as insulation in DRY conditions. In particular it functions well in floors, ceilings and walls (provided it can be kept dry) and is actually great for refrigeration applications.
However if the same foam is exposed to steam, the insulation it might offer is rapidly reduced to something equivalent to wet plywood.

Then why is foam still being used in hot tub covers? It’s cheap and it’s the industry standard. Though perhaps just because everybody is doing it doesn’t ensure it is the right idea.
A hundred years back the quality mode of travel was the horse. The horse had been the standard for years and years. Until something better was developed.
A better idea with regards to spa covers go would be the one that eliminates the foam, still insulates but stays light weight and simple to use.
Three decades ago, (yes really, thirty years ago) that really is the way in which the SpaCap was created. A single woman with back pain, needed to be able to get into her hot tub every day for therapy. She had to be able to get her cover on and off by herself without further injuring her back.
The Spa Cover she eventually created was light weight, easy to use and insulated as well as a foam filled spa cover. Although it has gone through many improvements over the years, the basic idea and principle continues to be exactly the same. SpaCap.com builds custom spa covers for all kinds of spas including Swim Spas.
Don’t go out and buy another foam filled spa cover just because that’s what the neighbors do. Visit SpaCap.com and purchase a spa cover that won’t become saturated and heavy or break and is going to make it easy for you to use your spa year after year!

Indications It’s Time For a New Spa Cover

Hot Tub Covers are imperative, if you would like to have the water warm within the hot tub. Unfortunately, they don’t last forever. Despite what your spa dealer could have promised, there is going to come an occasion that you will need a replacement hot tub cover.
How can you tell when the hot tub cover has given up the ghost? There are obvious signs, as well as some that aren’t so obvious indicators. Here’s 5 indications of spa cover distress to think about.
Saggy Cover
If by chance your foam filled hot tub cover collects water on the outside, you’re going to need a new spa cover. It signifies that whatever was employed with regards to the reinforcement of the foam boards has become bent or broken. There is typically a C-channel that runs along both halves of the spa cover, where they meet in order to support each side across the middle by the hinge. Some cover manufacturers will use materials like aluminum or thin steel at this point which will bend under weight (dogs, kids, snow), or (more typically) from the weight of the cover itself.
If that is the case, trying to milk a longer time out of the cover is only going to set you back more going forward since whatever insulation value it may have had is gone at this point. Delaying the inevitable is only going to cost you more in your energy consumption. But more importantly from a usage perspective, you are likely not going to desire to mess with your cover when it has water on top of it. Ultimately, you’re utilizing your hot tub less that is definitely a sin. Which would make you a sinner.
Something to think about here. Regardless of what your hot tub dealer may have to say about it, if he only offers to sell you another foam filled cover, it is 100% absolutely going to finish up just like the one you have to replace now.
It won’t matter if it happens to be shrink wrapped in Kevlar and reinforced with titanium, if it has foam in it, it is doomed to fail.
Puddle Cover
Water is heavy, at 8 lbs per gallon, it adds up quickly. Another case of broken reinforcement channel. Probably started with a small crimp in the channel, which started to puddle some water, which allowed for more water … and now it looks a new spa cover is in order.
Much like Saggy Cover, this is due to using foam panels over a hot tub. Foam panels will absorb moisture from the steam being released the spa water. Nothing will prevent it short of not using foam in the cover!
The spa dealer may suggest you to try to flip the panels over contained in the cover to add to the life. Only those zippers as well as the vinyl material weren’t designed to be opened and shut past the initial stuffing of the foam.
As soon as the cover begins a gradual puddle, it may never be reversed. It is definitely time to purchase a replacement hot tub cover. Same as stated above, putting it off means you’re going to be making use of the hot tub less (a sin) and wasting money on your heating bill.
Water Logged Spa Cover
This is a spa cover that weighs about 3x what you had when it was new. They actually can get so heavy that they will become almost impossible to use without the aid of a Seal Team. They often also damage spa cover lifters if they get too heavy. This is because the cover lifter is not designed to handle the weight of a saturated cover. Bet the dealer didn’t bring that up when he sold it to you.
happens when the foam core is taking on water – and, is not draining. This does not indicate that rain water has somehow got into your cover, or snow or another outside source. It is the natural result when steam rises from the warm spa water and after which since it’s a very small molecule, gets up into the foam. Once it gets up in the foam it cools and turns back into water, and becomes trapped due to the reason that the water molecule is too big to drop out.
The best way to prevent it would be to never use a foam filled cover on a hot tub. In spite of what the manufacturer claims to wrap it in or the way they package it, the foam will eventually become saturated. Period.
It is time to get a new replacement hot tub cover. Again, putting it off now is just going to end up costing you more in your energy bills and unless you happen to have a Seal Team living with you, you are not going to be using your spa many times. (still a sin)
Should you wish to be clever, it is possible you can remove the cover off your spa and store it in your garage for a few months. As soon as the cover is off of the moisture and stored in a dry place, eventually the moisture within the cover will evaporate (back to a smaller molecule) and the foam will become light again. It takes months for it to dry completely and that means you need to have another replacement cover so you can continue to use the spa during the time you wait. Note:The cover may still warp wildly out of shape while it dries.
If you rotate your covers every three months, you may be fortunate enough to make them last till the materials finally come apart. See Below.
Torn & Worn Spa Cover
When the fabric (marine grade vinyl on the standard foam filled spa covers) suffers from its limit of sun and weather, it becomes brittle and begins to deteriorate. Eventually, holes and tears occur that will .
Due to the fact that ALL Vinyls, which includes most expensive Marine Grade, are rated by HOURS outdoors.
Using a spa cover protectant is just another method for hot tub cover dealers to take your money. If you want to spend on weekly basis rubbing down your hot tub cover with conditioner, be our guest but the smart thing to do should be to purchase a cover that doesn’t have VINYL on the outside.
Still, if the cover isn’t heavy yet, you might to postpone getting a new one immediately providing you don’t mind the look of Duct Tape. If you would like some tips, have a look at some episodes of the “Red Green Show.” Red covers the finer points of Duct Tape.
Smelly Spa Cover
Musty, mildew, old wet dog – whatever your spa cover smells like, if it’s a bad odor, that probably indicates that you have bacteria forming inside the hot tub cover. It probably also means the spa cover is water logging (see above).
Now we have crossed over from inconvenient to unhealthy.
What are you inhaling if this is what you smell?
Completely dismantling your cover, and spraying it down with Lysol won’t help! Because the source of the smell, AKA the mold and mildew are stuck inside the foam! At most you will probably be able to kill what’s on the exterior of the vinyl or foam however you are not going to touch what’s inside the foam. Plus now your cover smells like Lysol, nothing kills the mood faster than inhaling something that reminds you of how the school janitor cleaned up vomit.

The origin of the problem? That high quality foam used for traditional Hot Tub Covers. Regardless of how much a dealer may attempt to sell how it is amazingly resistant to water absorption and bacteria formation, it will still happen and they realize it.
When you happen to be ready for a new spa cover, be sure that it’s not made using a foam core.
