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.

"Terrible! Wish I had gone with another company. Here is the issue with Heavenly Heat. If your sauna arrives damaged or and issue arrives -- they have zero technical support. Your repairs will be done by any "joe" that heavenly heat finds to do the repair in your area. They will have no experience with Sauna's and are given no instructions regarding the chemical free aspect of these sauna's. The worst part is the buyer, me, was treated as if I was the problem for wanting my sauna repaired correctly. I would have refused the delivery had I realized I was receiving a damaged sauna and would have to spend hours and days trying to get this resolved. The owner, Bob Morgan, is extremely responsive before he has your money but after, is a different story. When inquiring about the sauna he would respond generally within 10 minutes. After you purchase, and particularly if you have a problem with it, you are treated as if you're a nuisance. My sister bought a competitors sauna around the same time and the service she received from knowledgable representatives was a world of difference from my experience. My other issue was that there were shipping delays and Bob would never communicate them. I would have to pursue him to get information. I think they make a decent sauna but I would not recommend for reasons stated above."

Pool and Spa Servicing questions, answered by experts

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.

Using bubble bath, bath oils, bath salts, or moisturizing products that contain butters or oils can damage your jetted tub. Because of the water pump and jet mechanism, you need to be more selective with products for a jetted tub than you would for a traditional bathtub in order to keep it functioning properly and avoid expensive repairs. These products also leave residue that can feed mildew and mold, so it’s best to avoid them.

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.

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

Similar to a hot tub, swim spas last anywhere from five to 20 years, depending on quality and your attention to maintenance. The best way to increase the lifespan of your swim spa is to carefully maintain it—including draining it around every six months to deep clean the parts.
