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

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.

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

Hot tub maintenance can cost between $240 and $900 annually. These costs include deep cleaning the tub, refilling the tub several times a year, and keeping the water's chemical balance. Keeping up with regular maintenance and cleaning tasks can help to keep your costs down, as you'll avoid more complicated and expensive repairs.

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.

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.
