Heavenly Heat Infrared Saunas are made for the chemically sensitive. That means that our infrared saunas create an ideal, safe, and effective detoxification environment for anyone seeking to eliminate toxic substances from their body.

"I purchased a Heavenly Heat Sauna a few weeks ago . What I liked is you don?t smell any glues . I also liked its easy ( two man ) assembly. What I don?t like , in order to avoid using glues, they use pins or very thin nails. Some pins were missing and some were not beneath the surface. For the rough edges you?re provided with a small piece of sandpaper . Bot at a cost of over 5k you don?t expect to do sanding. My biggest complaint is that it takes almost an hour to get the sauna to 150 degrees. Definitely not worth the price. "

Pool and Spa Servicing questions, answered by experts

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

If water is left inside the hot tub pump over a cold winter, it could freeze and severely damage the pump, water lines, and jets. That can cause leaks, which require very expensive repairs. Freezing or leftover water can stain and damage the hot tub shell, which leads to replacement. Even in mild climates, leaving sitting water in the tub or pipes for a long period of unuse is a bad idea, since disinfecting chemicals fade and the water can develop bacteria, algae, and other big headaches when it’s time to use the tub again.

A compact unit designed for two to three people typically weighs approximately 500 pounds in its empty state. On the other hand, a larger hot tub meant for up to six people can weigh around 1,000 pounds when empty. Materials used also impact weight. Less expensive hot tubs are typically lighter because they are made of molded plastic or fiberglass.

Hot tub repairs cost between $200 and $500 on average. You can minimize those costs by maintaining your hot tub and keeping necessary supplies on hand. An elevated shelf in the garage is a great place to store your water care chemicals so that kids and pets will stay safe and you’ll always have them around. 

Your hot tub should be drained of existing water, cleaned, and refilled every three to four months at a minimum. Follow your tub manufacturer’s recommendations for cleaning, and rinse thoroughly when finished to eliminate any residue from the cleaning products. This is also a good time to inspect your tub’s cover in good lighting for any leaks, tears, or other damage that might cause problems. 

Using your hot tub manufacturer’s suggested cleaners and methods, keep your hot tub filters clean to avoid a loss of water heat. This will help extend the filter’s useful life and efficiency. If the filter is more than two to three years old, replace it with a new one and buy a second filter to keep around as a spare.
