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

If you don’t clean your hot tub filters, they’ll build up dirt and grime, preventing them from filtering out contaminants like dirt and bacteria. The dirty water will then circulate through the filter and back into the hot tub, leading to dirty water, a damaged pump and jets, and low heat. This can lead to higher hot tub costs because you may have to pay for repairs.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

You should drain your hot tub three to four times a year to give it a thorough cleaning. This should take about an hour, but it depends on the size of your tub.

Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.

You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don’t add chlorine to your hot tub water more than once per day.
