Know before you buy
This heater is designed for medium to large sauna rooms ranging from 283 to 706 cubic feet. If your sauna falls outside this range, the heater may either underperform or create an uncomfortably intense environment.
Yes, as a wood-burning unit, it must be connected to a properly installed chimney system that meets local building and fire safety codes. Ensure your installation site can accommodate the necessary flue venting requirements.
The Harvia Pro 20 SS requires 40.82 kg (88 lbs) of sauna stones. Using the correct amount of stones is essential for maintaining consistent heat and producing the signature 'löyly' steam when water is poured over them.
Yes, the unit features adjustable feet, which are helpful for ensuring the stove sits level on uneven floor surfaces. This stability is important for both the safety and the longevity of the steel construction.
Routine maintenance includes clearing ash from the firebox and periodically checking the sauna stones for cracks or crumbling. You should replace the stones annually or more frequently if you use the sauna daily to ensure efficient heat distribution.
The cast-iron framed glass door allows you to monitor the fire level without opening the door, which helps maintain consistent heat inside the firebox. Beyond its utility, it provides the cozy, ambient glow of a traditional fireplace.
