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.""

officially established in 1985, I have been designing and building many different things since I was a child. Advertising my company as a GENERAL BUILDING/DEMOLITION CONTRACTOR is an understatement. WE do odd jobs, handyman repairs of just about anything made by man, HOME IMPROVEMENTS, and start to finish building projects.

Pool and Spa Servicing questions, answered by experts

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.

It’s possible to move a hot tub on its side or base as long as it fits snugly in the moving truck, with plenty of padding around it. This moving method requires specialized equipment and careful planning, like moving straps, dollies, and moving blankets.

You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don’t add chlorine to your hot tub water more than once per day.

Properly maintaining your hot tub will prevent serious issues from occurring down the road. You should replace the filter once a year, regularly look for and repair small cracks in the shell, and test the water quality every few months. You can do this yourself for less than $100 per year.

You can also hire a hot tub service to service your hot tub annually to identify problems early, which could save you money in the long run. They cost about $100 to $200 per call.

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.
