The power of a sauna heater is measured in kilowatts (kW). The larger your sauna (and the more "cold surfaces" β glass, tile, stone, etc. β the interior of the sauna has), the more kWs your heater needs. Use this simple tool to tell us about your sauna, and we'll tell you exactly how many kWs your sauna heater should have and send you directly to the perfect heaters.
