The Forte is Harvia’s innovative version of the heat-storing electric heater, combining top-of-the-range heater technology with a sleek design. Just grab a towel, lift the Forte’s cover and climb onto the bench to enjoy humid and gentle steam. The Forte is equipped with a separate splash-Proof control panel. Forte’s new Properties provide family saunas with a sense of safety. The heater will turn off automatically if you forget to close the cover, and the control panel has a keypad lock. The new ECO mode saves electricity, as it allows you to adjust the heater’s temperature to a very low setting without turning off the heater.
