Skamet P-21640 wood-burning sauna heater with extended firebox and optional 40 L stainless-steel water tank for 8–18 m³ saunas, heated from adjacent room

The Skamet P-21640 combines reliable Estonian craftsmanship with functional design. It is built for medium-sized saunas and features an extended firebox, which allows heating the sauna from another room — perfect for installations where the stove door should open into a dressing area or technical space.

This model can be equipped with an open 40 L stainless-steel water tank with a tap, providing a convenient way to heat water for washing while heating the sauna. The tank can be positioned on either the left or right side, depending on the sauna layout.

With a stone capacity of around 40 kg and space for firewood up to 60 cm long, the P-21640 delivers stable, even heat and a pleasant steam experience. The heater’s durable metal casing is coated with black heat-resistant paint, while stainless-steel details add a modern touch. Optional glass-door versions enhance the ambiance by allowing you to enjoy the warm glow of the fire from the adjacent room.
