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 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. 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.

Yes, hot tubs are meant to be kept on permanently. It takes more energy to ramp up a hot tub when you turn it on, so leaving it on all the time is more efficient for your hot tub. You can turn the temperature down if you know you won’t be using it for an extended period of time to save on energy costs.

The average life expectancy of a hot tub cover is between five and seven years. You can extend the life of yours by keeping it clean, using a soft cloth and mild dish soap; applying a vinyl protectant spray; using a cover lift to move and fold the cover carefully, rather than treating it roughly; protecting it from harsh weather; keeping kids and pets off the cover; and cleaning the underside of the cover with a chlorine spray. Investing in a quality cover will also help it last longer and look better.

It’s easy to keep your hot tub clean and safe for all to enjoy by following a few simple tips:

  • Make sure anyone who uses the hot tub rinses themselves and their swimsuits off, perhaps in an outdoor shower near the hot tub. 

  • Don’t add anything to your hot tub’s water. Bath oils and bubble bath liquids might seem like a fun addition to your hot tub experience, but these substances will turn the water in your tub foamy and its surfaces hard to clean. 

  • Restrict eating in the tub to light snacks that you can easily clean out if there’s any spillage. Crumbs from crackers and chips can be difficult to pick up. 

  • Make it a no-pet zone. Pet fur and dander can pose a cleaning issue, but it’s also not a great idea for your pet’s health and safety.
