Good to know
Residential or light commercial?
Every PureHeat sauna is rated by the manufacturer as either residential or residential and light commercial. That label is a promise about how the unit was built and where its warranty holds. Here is what it means and how to pick with confidence.
The difference
It comes down to duty cycle.
One variable sits behind the whole distinction: how hard and how often the unit runs.
Residential
Used intermittently. A household enjoys it a few times a week, with cool-down between sessions. This is what these units are engineered and warranted for.
Full commercial
Cycles almost continuously, serving many users back to back, often fourteen or more hours a day. That is roughly ten to thirty times the intensity of a home.
Under the hood
What changes inside the unit.
Duty cycle drives the hardware. Three parts feel it most.
Heaters and emitters
Residential heaters and emitters are built for occasional use with cool-down. All-day cycling is a different kind of wear they are not rated to sustain.
Power electronics
Residential power supplies are matched to residential run times. Under continuous load they tend to wear out years early.
Cabin and hardware
All-day, many-user use means constant moisture, which is why true commercial builds lean on heavier materials and corrosion-resistant hardware.
Why it matters
The warranty follows the rating.
The rating is the biggest lever on your coverage. These warranties are written for residential use, and placing a unit into a commercial, pay-to-use, or shared-access setting is treated by the manufacturer as commercial use, which changes or limits the coverage.
So under-rating to save money can quietly cost more. Buy the unit rated for how you will actually use it, and both the coverage and the longevity stay intact.
Choosing
How to decide which you need.
Match the rating to your real use, not to how the box is labeled.
A private home
Used by you and your family a few sessions a week. A residential rating is exactly right, and it is what these units are warranted for.
A true gray zone
A short-term rental, a shared amenity in a small building, or a low-traffic studio. Residential and light commercial can fit, but confirm the warranty in writing with the maker first.
A gym or public spa
High-traffic, income-generating, many users a day. That is a full commercial project with its own code and electrical path, and a residential unit is not the right tool.
Reassurance
Buying a sauna for your home?
A residential rating is not a limitation to work around, it is the correct match. The unit was built and warranted for exactly the way you will use it. Buy the rating that fits your home and it will serve you for years.
