A wood-burning sauna heats its rocks with a real fire. It needs no electricity, which makes it a strong choice for a cottage or any site without power, and for many owners the fire itself is the whole point. In return it asks for more: you tend it, it takes longer to come up to heat, and it needs a proper chimney and safe clearances.
A wood-burning heater is a solid-fuel appliance, and it has to be installed as one. That means a correctly specified chimney, the manufacturer's minimum clearances from benches, walls and anything that can burn, a proper hearth or floor protection, and attention to how the flue passes through the roof. Check what your municipality requires, and check with your insurer, since some ask for a professional inspection on solid-fuel appliances.
Electric and wood-burning are both traditional saunas. Both heat rocks, both let you pour water for steam, and both run in the same temperature range. The difference is only in what heats the stones. See electric vs wood-burning sauna.
Procraft makes electric sauna heaters. We do not currently make a wood-burning heater, and we would rather tell you that plainly than pretend otherwise. If you have power at the site, our four electric models cover small indoor rooms up to large outdoor saunas in cold climates.
Procraft makes four CSA-approved electric sauna heaters. Every one includes 50 lbs of rocks, an integrated thermostat that heats to 110 degrees Celsius, a built-in 3-hour timer and a 5-year limited warranty.
