The Harvia TopClass KV-45-S is a 4.5 kW wall-mounted electric sauna heater designed for home saunas. Both its outer casing and its stone space are made of stainless steel, which resists corrosion and supports long-term durability. Mounted on the wall rather than standing on the floor, the heater saves space and integrates with the sauna interior. It is made in Finland.
Operation happens directly on the heater. A built-in control panel sits toward the top of the unit and is illuminated, so the settings remain easy to read in low-light conditions, and it can be set up on either the right or left side to suit the room layout. The controls include a 60-minute timer and an 8-hour delay time clock. Efficient air circulation maintains a consistent temperature throughout the sauna. The heater requires a minimum of 44.1 lbs of sauna stones, installs on a separate mounting rack and runs on 240V single-phase power. It is UL Listed for installation and operation in North America.
