How to select the right heater for your sauna?

Wood-burning or electric?

The first thing in heater selection is the decision between electric and wood-burning heaters. Wood burners are the best choice for saunas in general, but might not always be practical. City codes may limit wood burning, and firewood availability might be an issue. That's why electric heaters are a very popular and a good choice.
With the wood burning sauna heaters, the main thing to consider is the sauna size. Harvia wood burning heaters are good for saunas from 210 ft3 all the way to commercial size saunas of up to 1765 ft3.

Wood-burning heaters: inside or outside feed?

Other important decision choice is how you want to feed the firewood to the heater: from inside or outside the sauna? The models with letters "SL" in the name come with a longer fire chamber, that can be made to go through a wall. That will allow you to handle the firewood outside the sauna, keeping wood debris out.

Wood-burning heaters: add water heaters?

All wood burning heaters come with at least one option of water heater (chimney-mounted heater), and some have options for 2 or more heaters on the sides. These water heaters are perfect for off-grid saunas!
