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.

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.

Unfortunately, a hot tub does use a relatively large amount of electricity. In fact, much of the money you spend on your hot tub will go toward electricity costs to keep the water heated. A typical hot tub will use anywhere from 1,500 to 6,000 watts of electricity per month.

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

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.
