Understanding Heat & Temperature
Many customers ask about exact heat-up times and maximum temperatures. Here's why those numbers vary—and why they matter less than you might think.
Why we don't list specific max temperatures
Your sauna's ambient temperature and available power draw significantly impact both heat-up time and maximum temperature—factors outside our control. More importantly, focusing on "max temp" misses how infrared therapy actually works.
How to use your sauna effectively
Get in when the sauna reaches 90-110°F and enjoy your session as it continues heating. This keeps the heaters running continuously, maximizing your infrared exposure. If you wait until it hits your target temp, the heaters will cycle on and off throughout your session, reducing therapeutic benefit.
Tip
Listen for a small "click" sound—this tells you when heaters are cycling on or off as they reach the set temperature. Don't touch heaters to check.
Infrared vs Traditional Heat
With traditional Finnish sauna research making headlines, it's natural to wonder how infrared compares. The short answer: they're different modalities with different benefits—not better or worse, just different.
Why people fixate on temperature: Recent Finnish research (using traditional heaters at 176-194°F) has driven massive interest in sauna therapy. Naturally, people assume they need those exact temperatures. But infrared heat is fundamentally different.
Intensity
Infrared heat is more intense than traditional heat at the same temperature. It penetrates tissue more deeply, while traditional heat works primarily through hot air.
Research application
While the Finnish studies didn't use infrared, we believe—based on mechanistic understanding—that infrared at comparable dosages provides similar benefits. This is our professional opinion, not medical advice. Consult your doctor.
Accessibility
Infrared's popularity stems partly from convenience. Most infrared saunas plug into standard outlets, while traditional saunas require electricians to install 240V circuits—a significant barrier for many people.
Bottom line
Absence of evidence is not evidence of absence. Infrared's different mechanism doesn't diminish its therapeutic potential.

Cannot say enough good things about this company. Upon first starting my research into getting a sauna, customer service was not a priority. After talking to Heavenly Heat, they said it was one of their main things - and turns out you will probably run into some thing you need to work out and Heavenly Heat's customer service is the best. Super helpful, responsive and take care of you. Highly recommend & the sauna's are magnificent as well.

Ordered our 1 person sauna online after Matt Justice reviews on YouTube. Was delivered very quick. Assembly was easy and almost no tools. Loved the operation of the sauna. Fast heat, great quality, and feel so good after sessions.
We had to move the sauna to a new house and tookmit apart. On assembly there was no heat from the back heaters. The company just sent us a new one free and free shipping. That worked perfect and were back to enjoying the sauna.
Rare customer service. Could not recommend this company more.

I sleep better! I have reduced BP, resting heart rate, and resting respiratory rate too. All within 2 weeks of 30 minute sessions 3-4 times a week. I should have ponied up the $ and started heat therapy earlier in my life.
J
Warren was super helpful with the installation questions I had. Only giving 4 stars because I wish they had more size options, but I understand why they keep their line limited to maintain quality. The no-plywood construction is a game changer for someone with chemical sensitivities.
J
Finally pulled the trigger after following Matt Justice's sauna content for a year. Called Heavenly Heat and had an amazing conversation with John about EMF levels and wood quality. This isn't a mass-produced unit - it's truly handcrafted. Two months in and my sleep has improved dramatically. The Canadian hemlock construction makes such a difference in air quality.
