Polar HMR product guide
NOTE: First, calculate your sauna volume and for each sqft of glass or tile surface add 10 cubic feet to the calculation. Then look in the linked guide the required heater power. We recommend to choose the power version for your sauna on the upper side (so for a 200 cubic foot sauna choose the 6 kW instead of the 4,5 kW.)
We recommend to install the heater as low on the wall as allowed, not like in many pictures you see on the internet where sauna heaters are installed quite high on the wall.
