With 8 kW of output, the Harvia TopClass KV-80-S is a wall-mounted electric sauna heater intended for larger home saunas of 250 to 425 cubic feet. Durable stainless steel is used for the outer casing as well as the stone space, giving the heater corrosion resistance that supports longevity and reliability. Its wall-mounted design saves space and integrates cleanly with the surrounding sauna interior, and the heater is made in Finland.
The KV-80-S has its controls built in. An illuminated panel positioned toward the top side remains usable in dim sauna lighting and can sit on either the right or left side of the heater, depending on where it is placed. Timing is handled by a 60-minute timer paired with an 8-hour delay time clock. Thanks to efficient air circulation, the temperature stays consistent across the room. Its stone requirement starts at 44.1 lbs of sauna stones, and the heater is fitted on a separate mounting rack. It operates on 240V single-phase power and is UL Listed for North America.
