Fire, stone and the setup around them Have a wood-heater question? Ask away. We can help you understand the product before you build around it.

A wood-burning heater involves more than choosing a stove. Chimney routing, room volume, clearances, stones, protective surfaces and the surrounding sauna design all matter. If one part of the setup is unclear, send us the question before ordering.
