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.

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Regular water testing, filter cleaning, and chemical balancing are essential for keeping water clean and equipment functional.

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.

Yes, air baths are good for you. They promote relaxation, improve circulation, and can even hydrate your skin. Since they’re gentler than water jets and whirlpools, they are a good choice for a wide range of homes and users, from children to adults. You can maximize the benefits by using them regularly for stress relief and by pairing the bubble effects with calming music, low lighting or chronotherapy, aromatherapy, and other relaxation techniques.
