If your Hot Tub Cover looks like this, maybe It's time to consider something different.
If you have a question you don't see answered below, please ask it by chat or email.
What are these Hot Tub Covers made out of?
SpaCap Hot Tub Covers are made from top quality marine materials. Our Deluxe SpaCap in Sunbrella marine grade fabric is the same material used on the most expensive yachts in the world. Sunbrella is quite literally the world standard in outdoor fabric. All vinyl including the best quality Marine grade is rated by HOURS outdoors and Sunbrella is rated by years. The air chambers and underside of the SpaCap Hot Tub Cover is a vinyl-coated fabric similar to that used for Achilles and Zodiac inflatable boats. It has a base polyester fabric that is then coated with vinyl on both sides. It is the same fabric used in commercial fertilizer bin tarps and commercial truck tarps. That means the material can handle some of the harshest chemical environments. The stitching is the same weight thread used to make truck tarps. In twenty years, we have yet to see a SpaCap Hot Tub Cover come apart at the stitching. All in all, we build every SpaCap Cover as if it were going on our own hot tub. They are truly built to last and to look good for years to come!
Is This Your Idea Of a "Wind Proof" Hot Tub Cover?
Can these Hot Tub Covers handle a snow load?
SpaCap Hot Tub Covers handle snow better than any rigid foam filled spa cover. When covered in snow, the typical rigid foam Spa Cover acts like a frozen bridge. When the snow gets too heavy, the rigid foam will sag or break. The SpaCap rests right on the surface of the water, so no matter how much snow accumulates, the SpaCap cover transfers all the weight evenly to the water. We have been selling the SpaCap Hot Tub Covers in snow country for years. These Hot Tub Covers have gone through world record snowfalls and to date with thousands sold around the world there has not been even one crushed by a snow load.

My last Spa Cover is "Gone With The Wind." Can SpaCap Hot Tub Covers handle the wind?
We'll explain why our covers can handle the wind but first the facts:
In thirty years not even one of these has ever blown away even in Hurricanes and Tornados.
The reason our Hot Tub Covers stay put no matter how strong the wind blows is they make a lousy wing. There is nothing rigid for the wind to use to create lift!. Whereas foam hot tub covers that are too heavy to lift will still fly away given enough wind.
Plus since the SpaCap rests directly on the water's surface, there is no air space under it that the wind can use to pop it off the hot tub. Given enough wind, a heavy rigid foam filled hot tub cover will start to lift off the spa due to negative pressure, caused by airflow. Once that happens the wind can rush into the airspace below that foam cover and push it up from the bottom at which point you have "Lift Off" and your hot tub cover is on its' way to parts unknown.
A customer in Kansas told us they saw a SpaCap on their local news. In a shot showing the devastation caused by a tornado the camera panned past a SpaCap Hot Tub Cover still sitting on top of its owners spa despite the fact that most of the neighborhood was destroyed.
The video below was shot driving down the freeway at seventy miles per hour. Please don't try this with a rigid Hot Tub Cover.
We get a lot of people that ask if our Hot Tub Covers will stay on in the wind, so we put it to the test.
This a Spa Cover being wind tested
We would do the same with a traditional foam filled hot tub cover being tested however State Patrol frowns on debris flying off a moving vehicle.
Can I fold it in half like I did my old Hot Tub Cover?
To expose only a portion of the hot tub we recommend that you only remove the SpaCap Hot Tub Cover as much as you want. Leave the hot tub cover partially on the spa. You can fold it back, but it's different then the hard foam hot tub cover. That's why SpaCap Hot Tub Covers work.
Sure you can fold your foam spa cover in half, but is that a good idea?
Can I use a lifter with a SpaCap Hot Tub Cover?
Sure but you won't need one.
We usually tell customers that want to use their lifter to put some of that foam pipe insulation (looks like a tube) that you can get from the local hardware store and cover the lifter with it to keep the bar from turning the cover black. You may also have to adjust where the lifter pivots from to allow for the extra bulk of the air filled cover.
One of the things the spa dealer that sold you the lifter didn't mention is that once the foam in their cover gets saturated, that lifter is never going to do the job. A heavy foam hot tub cover will either rip itself apart at the seams or worse, rip the sides off your hot tub where the lifter is attached.
That won't happen with a SpaCap Hot Tub Cover.
Does the SpaCap have an "Energy Star" rating?
Actually, no hot tub cover does. But if there ever was a hot tub cover that deserved one it would be the SpaCap.
is run by the US Environmental Protection Agency and the US Department of Energy. It is a great idea and has helped manufacturers move toward more energy efficient products in many different areas. Unfortunately though since it is a program paid for with tax dollars it has to be limited in scope or targeted so that the products it covers would be something that the majority of tax payers could see a benefit in.
It would be really great if Every product or innovation that reduced the energy required could be considered however such is not the case. Understandably the program is focused on general energy consumption of household products, washing machines, refrigerators, and materials used in home construction that reduce energy needs. Some products used in the home, for example computers are included, others in particular pools and spas are not.
Unfortunate considering the information we get from utility companies around the country regarding the cost of energy and the percentage of it that goes into a pool or spa. We have even seen the Energy Star logo used in advertising spas even though the Department of Energy has clearly stated that it will not consider such a product for inclusion as an Energy Star Partner since the majority of taxpayers would not benefit from such a product. This is naturally something we would like to see changed.
Personally we would be in favor of every tax payer owning at least one Hot tub. If more people would spend more time in their spa they would be using less fuel running around and have a lot less stress. Some utility companies have reported that when a home owner adds a hot tub their utility bill will go up by a significant percentage.
According to the findings of a 2004 study conducted by the Davis Energy Group sponsored Pacific Gas & Electric Co., pool and spa pumps are almost always the largest single electrical end-use (appliance in a home), using more than three times the energy of a new refrigerator. This same study found that the average residential pool pump consumes 2,600 kilowatt hours (kwh) annually with portable spas not far behind at 2,500 kwh per year. With an estimated 1.2 million pools and about half a million spas, the State of California requires the entire yearly output of one nuclear power plant PLUS one conventional power plant just to feed the consumption of pools and spas.
It's no wonder the California Energy Commission has recently approved new appliance efficiency regulations that for the first time include portable spas and a maximum allowable watt per hour usage. As spa manufacturers struggle to meet these new requirements the bottom line for you the spa owner is how do you reduce the expense of operating your already purchased hot tub? Since most of the energy used in the spa is used keeping the water warm for the next time you want to dip into it, getting that water insulated is the key.
[Hot Tub] Covers reduce most if not all of the evaporative losses from the pool when in use. With this component of heat loss being 70% a cover with a small R value can achieve as much as a 75% reduction in heating costs when used. (www.flasolar.com/heat_loss.htm)
If wrapping your water heater can make a difference in your energy bill, imagine what "wrapping" your other water heater (your spa) would do. Your hot tub uses the same type of heater your household water heater does only your household water heater may have twice as many elements to heat up about forty gallons of water while your spa is trying to heat four hundred gallons. Good insulation around the sides and bottom of your spa play a vital role in helping keep that spa water warm.
However that insulation is done when the spa is constructed. Any good hot tub manufacturer is going to put a good amount of insulation around the spa shell. Insulating the pipes the jets are fed from is important too and should be done by the manufacturer. Once you have purchased your spa insulating it after the construction can be done however it may be difficult and expensive. The last place most spa owners look for insulation is in the hot tub cover.
To begin with that spa dealer is going to send some sort of cover home with your new spa. The spa dealer may spend some time talking to you about the benefits of a cover but lets be honest you didn't go there to buy a spa cover and as an after thought decided to get a spa to go under it. No, you wanted a spa. One with lots of features. Jets where you wanted them to ease your pain and tension. If the spa dealer talked to you about the cover you might have seen his lips moving but you were still concentrating on how good those jets of water were going to feel as they pummeled your aching body with soothing pulsing action of warm water. You may have not even thought of the cover when you got your first utility bill.
But you should think about the cover since heat rises. Most of the heat lost from your spa water is going straight up. Insulating the water from the water then makes the most sense. But rigid foam covers are trying to insulate your spa water from way up on top of the spa acrylic. In most cases this can be several inches off the water surface, ten or more is not uncommon. If you have a rigid foam cover twelve inches thick it still doesn't insulate the water since it isn't in contact with the water. you loose heat under the rigid cover because warm water is evaporating, turning into steam. The steam rises and either escapes from the crack between the halves of the cover or hits the bottom of the spa cover, cools and condenses back into liquid and falls (cooled) back into the spa water below. In your car you would call this a radiator and consider it good because it keeps your engine cool. In your spa this is bad because it causes your spa to work harder to keep your spa water up to temperature. This is despite the fact that the outside of the rigid foam cover can be the same temperature as the ambient air outside, giving the impression that it must be insulating. The simple explanation for this is that the rigid foam spa cover is in contact with the ambient air outside the spa and NOT the water it is supposed to keep warm.
The SpaCap Hot Tub Covers by comparison is laying right on the water surface. By doing so it severely limits the evaporation by taking away that open surface. The SpaCap spa cover insulates using enclosed air chamber like a storm window. These dead air chambers insulate consistently regardless of the temperature outside or the age of the cover. The SpaCap has no foam in it to saturate or break so a five year old hot tub cover can insulate as well as a brand new one. We have had the SpaCap tested by an independent testing facility (information listed on our website) and have proven that our spa cover insulates several times better than any foam cover. That being said we would consider it a honor to be considered an Energy Star Partner. However unless the Department of Energy changes its scope to include Any consumer product that can save energy, that can't happen.
We will continue to pursue that end but for the foreseeable future if you see any hot tub or spa or spa cover advertising that they are an Energy Star partner you should report it to the Department of Energy, Energy Star, enforcement division and consider any other sales claims they make questionable. With the Title 20, Section 1605.3 amendments of the California Appliance Efficiency Regulations, that state is taking the lead in setting tougher standards for the energy consumption of portable spas. Other states will no doubt follow suit. With the biggest waste of warmth which equals energy spent going out the top, look for the best insulating spa cover to be the answer for the seriously energy conscious spa manufacturer. The Energy Star may never be offered to Spas or Spa Covers but it won't be long before meeting the California Regulations for spa energy consumption will be equal to the best endorsement.
