Washington State Vedolux approved boilers
Washington State has a very strict wood burning policy. At the time of this post, Feb 26 2020, only 4 options for “stick-wood” type boilers allowed for installation in the state. Varmebaronen has two of the options with the Vedolux 350 and 450. This is a link to the WA state’s current pdf of their approved wood-fired boilers.
