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."

""Unfortunately, our experience has been extremely disappointing. Communication throughout the process has been poor, with long stretches of silence and repeated failure to respond to emails or calls. There was no clear follow-up on progress, and we constantly had to chase for updates. When we receive responses, they were often filled with vague explanations or shifting excuses for delays due to the weather. Timelines are consistently missed, and at no point have we felt the situation is being handled proactively or professionally. What could have been resolved with timely, honest communication and accountability continuously turns into a frustrating and drawn-out ordeal.""

Pool and Spa Servicing questions, answered by experts

Most hot tubs use between 1,500 watts and 6,000 watts of electricity, depending on the voltage of your heater. 120-volt heaters tip toward the low end, and 240-volt heaters tip toward the high end. Expect your pump to add another 1,500 watts. Newer, energy-efficient models use less electricity, while older models use more.

Most outdoor hot tubs last between five and 20 years, excluding inflatable tubs, which last five to seven years. High-quality, maintained tubs can last decades, while low-quality, poorly maintained tubs may not hit five years. A good warranty, professional installation, quality materials, and proper maintenance will help a tub last longer.

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.

You’ll know you need to replace the pump in your hot tub if you hear loud or unusual noises when the machine is running or notice a significant decrease in water pressure. A leak or altogether failure of the hot tub may also indicate a problem with the pump, but you’ll need a professional to investigate the source of the issue.

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.
