Misa HEV1 Wood Sauna Stove

Inspired by everything Finnish, sisu (tenacity), and heavy metal, Misa HEV1 wood-burning sauna heater is for true (and a little crazy) sauna enthusiasts.

Once installed and stones stacked, Misa HEV1 weighs a whopping 743 lbs, which means many prefabricated sauna kits make it laugh. Biggest fans of Misa HEV1 get it first and only then build a suitable and big enough sauna for it.

Misa HEV1 is made of 50% thicker materials than Misa’s other stoves. Its firebox material thickness is 6–12 mm which is twice or even thrice thicker than with some competitors and matters the most, as it translates to longest possible lifespan.

Not for dry sauna people. Extremely sturdy, modern, and matte Misa HEV1 is all about löyly (steam) that never ends.

(Note that Misa recommends a mix of smaller and bigger sauna stones for best performance and ventilation.)
