Shop the Best Selection of Sauna Heaters For Sale Online
Matching your sauna heater output and cabin volume separates a sauna that works from one that disappoints every session. We carry Harvia sauna heaters and HUUM sauna heaters, along with Saunum and Scandia electric sauna heaters, so you can choose the perfect model for your budget and preferences.
We carry mini sauna heaters in the 3.5 to 4.5 kW range for small saunas. Most saunas rely on something in the 6 to 9 kW range. Larger or commercial setups push past 12 kW. Our team is a click or call away to help you navigate the sizing side of things.
Most models are available as complete packages with the controller and stones included, or as standalone units if you already have a controller or want to source components separately.

Frequently Asked Questions
What type of heater is best for a sauna?
You need to know your cabin's cubic footage before you buy a sauna heater so you can size it right. An electric sauna heater makes more sense for the vast majority of homes because installation is so much simpler (as is maintenance). These keep temperatures dialed in better, too. Wood-burning is only worth it if you’re willing to keep a steady stock of firewood and deal with the chimney maintenance. A gas sauna heater works well for commercial settings. We carry it all.
What's the difference between an electric heater and a wood-burning sauna stove?
Electric plugs into a 240V circuit and holds whatever temperature you set. Way less guesswork (and work, period). Wood-burning sauna stoves need a chimney and firewood, and you have to tend the fire throughout your session. The heat output is comparable. The ritual, costs, and maintenance are where they diverge.
How fast can my sauna heat up?
Electric heaters bring a well-insulated cabin to the perfect temp in 30 to 45 minutes. Wood stoves take closer to an hour (depending on the fire). Smaller cabins heat faster, and higher kW output helps across the board.
How does stone placement affect sauna heating?
Stones store heat and release it as steam. Airflow gets choked if you pack them too tight, which causes uneven heating. Too loose and they won't hold enough energy for a good pour. Follow the loading pattern in your heater's manual.
How do I pour water over sauna stones to create steam?
Slowly! A little goes a long way to produce a sharp burst of dry steam. Dumping a full ladle drops the stone temperature and gives you weak, wet steam instead. Let the stones recover between pours.
How often do sauna stones need to be replaced?
Every 1-2 years with regular use. Stones crack from constant heating and cooling cycles. Swap them out as soon as they start crumbling or packing down. Broken fragments compromise airflow and can take a toll on your heating elements.
How long do sauna heaters last (and do they have a warranty)?
10-20 years. Heating elements wear out first, usually after 5-10 years of steady use. Every heater we sell ships with the full manufacturer's warranty.
What are some warning signs that the heating elements are going bad?
The cabin is taking longer to heat than it used to. You might see elements glowing unevenly or not lighting up at all. Cold spots in the cabin are another tell. Check the elements first if performance has been declining gradually.
Can I just replace heating elements in a heater?
Yes, at least most of the time. Harvia and HUUM both sell replacement elements for their electric models. It's an easy swap if you're comfortable with basic electrical work, but hiring an electrician is the safer route. Either way, replacing elements costs far less than a new heater.
