The Harvia Topclass KV-80 8kW sauna heater is a user-friendly heater that features an outer casing and stone space made of durable and corrosion-resistant stainless steel. Its illuminated control panel is placed on the side of the heater towards the top section, which makes it easy to access the switches even in the dim lighting of a sauna room. The sauna heater mounts easily on a separate mounting rack, and the control panel can be mounted either on the right side or the left side of the heater as needed. The Topclass KV-80 is designed for sauna rooms from 250 to 425 cubic feet.

The Heart Of The Sauna

Be it an electric or a wood-burning heater, steamy or dry, one thing is for sure; it heals you. Harvia’s heaters are your traditional source for modern well-being.

From the beginning, Harvia’s heaters have been forged with quality as a priority. With over 70 years of craftsmanship, Harvia heaters are reliably built to last. Easy to use, practical, and safe – you are sure to find a fitting heater for your sauna.

Your Sauna's Powerhouse

The right heater is the heart, and part of the interior and atmosphere of the sauna. From our selection, you can find the right electric heater and design for your needs. You can also choose the heater based on your steam preferences. A large stone capacity in pillar heaters provides soft steam. If you like dry and hot steam, then a smaller stone amount in our wall-mounted heater is perfect for you. Our product range offers solutions for both home and commercial use.

The power of the electric heater is based on the size of the sauna and the interior materials used in the sauna. An average of 1 kW of heater power is required per cubic meter of sauna volume. The need for power increases if the sauna has window or glass surfaces or heat-storing surfaces, such as brick or concrete.

Hot and dry vs. a gentle and steamy sauna?

Some like hot and dry saunas, whereas some prefer softer, gentler and more steam room-like saunas. Both ways of enjoying sauna bathing have their own benefits.
