The Harvia KIP heater is a traditional wall-mounted sauna heater with built in controls. The heater is constructed of stainless steel inside and out and the exterior is polished for added beauty. The heater includes a protective stone guard. The heater has a large stone cavity for maximum heat release, and the dual wall construction allows the exterior to remain cool to the touch. The left dial controls the temperature and the right dial is the on/off control along with a delay timer. You can set the heater to turn on up to 8 hours after it is set, and the heater will automatically shut off after 60 minutes of operation. Almost Heaven Saunas provides a 5-year warranty on all sauna heater components for residential usage.
