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."

We sell and install in ground and above ground pools. We also sell Hot Spring spas. We do not use subcontractors. We are open all year round.

"Purchased a hot tub from the Hagerstown store which went great. In January 2025 got a leak in hot tub. Serviceman came out repaired it $350 advised wait on warm weather to refill. Since a few days nice weather filled it yesterday only to fine it’s not fixed. Called service that had a manager call me who advised it my problem and would cost another $350 for them to look at it. Never used the Hot tub since it was fixed. They have lost a client over this. Manager it’s not always about the money but what’s right for the client."

Pool and Spa Servicing questions, answered by experts

Most newer hot tubs are not expensive to maintain. Hot tub maintenance costs about $500 to $1,000 per year. You can DIY, but a pro can clean and treat your hot tub with chemicals and save you time. The biggest hot tub expenses are heating and repairs, but you can preserve your investment with regular maintenance.

Yes, they provide full-service inspections, identifying and resolving any potential equipment problems.

Most hot tub motors can last between five and 10 years; however, hot tub motors can burn out sooner if the hot tub water is not maintained or if the motors themselves are not maintained or protected from the elements. Since hot tub motors (also referred to as spa pumps) power the jets and circulate the water, they are important for the functioning of your spa. Buying a quality motor, keeping the hot tub filter clean, and keeping the wet end of the motor wet and the dry end dry can help them last longer.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

Hot tub repairs cost between $200 and $500 on average. You can minimize those costs by maintaining your hot tub and keeping necessary supplies on hand. An elevated shelf in the garage is a great place to store your water care chemicals so that kids and pets will stay safe and you’ll always have them around. 

Your hot tub should be drained of existing water, cleaned, and refilled every three to four months at a minimum. Follow your tub manufacturer’s recommendations for cleaning, and rinse thoroughly when finished to eliminate any residue from the cleaning products. This is also a good time to inspect your tub’s cover in good lighting for any leaks, tears, or other damage that might cause problems. 

Using your hot tub manufacturer’s suggested cleaners and methods, keep your hot tub filters clean to avoid a loss of water heat. This will help extend the filter’s useful life and efficiency. If the filter is more than two to three years old, replace it with a new one and buy a second filter to keep around as a spare.
