The large stone mass of the Saunasampo Smart Sauna Heater acts both as a heat storage and a heat exchanger. When the lid is closed, the heater functions as a heat storage unit, and when the lid is open, it works as a heat exchanger that transfers the heat stored in the stones into the sauna.
The heater heats the air rather than the materials themselves; consequently, the sauna’s surface materials remain in good condition for significantly longer, energy is saved, and the steam produced is soft and moist. During the heating phase, the heater’s lid remains closed, resulting in an average energy saving of 50% compared to traditional continuously heated sauna stove models.
Cut your energy consumption in half
Saunasampo – a continuously heated sauna stove can pay for itself in as little as one year.

The Saunasampo Smart Heater is the world's first heat-storing electric sauna heater.
Inventor Tapio Yli-Kovero patented the sauna heater in 1987. It was unveiled at the Tampere Invention Fair in 1990. At that time, heaters typically held 20 kg of olivine-diabase stones, with a maximum of 40 kg; some commercial-grade heaters might hold 60 kg. Due to the small quantity of stones, the sauna had to be scorching hot to ensure the steam didn't run out prematurely.
The smart heater’s 200–300 kg stone capacity revolutionized the electric sauna heater market; it became possible to create an electric sauna that did not feel scorching hot but instead provided a gentle, humid steam. Due to the patent on the smart heater, other so-called "always-ready" heaters lack a fan, which limits their use to small saunas.
The first "Smart Heaters" were installed in 1994. Among the first units was the heater at Hotel & Resort Vanajanlinna in Hämeenlinna, which remains in use today. Smart Heaters are also found in the saunas of the Finnish Parliament—two for Members of Parliament and two for the staff.
Physically and functionally, the Smart Heater has not changed significantly. The only external change is the lid, which has shifted from cast aluminum to tempered glass. The control electronics have evolved from relay control via programmable logic to a digital system.
For reasons of durability and cleanliness, the switch has been made to using almost exclusively ceramic sauna stones manufactured by Kerkes in the heater.
The Saunasampo Smart Heater is ideally suited for saunas with high usage rates or frequent activity, where people are using the sauna throughout the day. Examples include fire stations, golf courses, police stations, hotels, gyms and sports centers, housing cooperatives, and large workplaces.
