Efficient Wood Stoves

mikeolder | Posted in Energy Efficiency and Durability on

Buddy of mine has plenty of wood to burn and used to have a outdoor hydronic wood burner.

What are the most efficient wood burner designs lately?

Thanks

    Jotul F55 v2 is around 70%. Passes the new EPA standards (2020). Some that are a little higher don't seem to work as well (glass is always dirty).

    I have a Lopi Endeavor stove and it's very efficient, with low particulate emissions, while still accepting 16" logs. There are various European stoves, by Morso, Rais and others that are even more efficient, though they often require logs shorter than 16".

    The EPA threshold for emissions is 2.5 grams per hour of ≤2.5 micron particulates. The Lopi Endeavor is rated for 1.4 gph. The European stoves are as low as 0.9 gph. Mine burns cleanly enough that our chimney cleaner said we could skip a year or two of cleaning.
