- MNMatthew N.Verified BuyerRated 5 out of 5 stars6 days agoGreat little wood stove
The stove works excellent. The draft is good, and I don't get any smoke smell inside the sauna, even when opening the door to refill. I highly recommend getting the Harvia rocks (instead of picking your own). They hold heat very well, and produce good steam. I do have to leave the ash box open just a crack so it has enough air intake. And also the fire box is small, so be aware that if you have a collection of wood already, you may have to cut them smaller to fit (13" max).
This was my first time building a sauna, it ended up being 9ft x 5ft x 7ft, which is 315ft³. This stove ended up being perfect, but I glad I didn't build the sauna any bigger. I live in a cold climate, where it is anywhere between -20F and 30F during the winter, and if the sauna was any bigger, I think it would be hard to get it up to 180F without having to refill the stove multiple times, and wait longer. As it is, I only fill it once, wait an hour, and then add a couple more pieces of wood when I enter the sauna.
