i quickly scanned the forum, but did not see this question covered, so forgive me if i missed it.
most of the plans and rocket mass heater examples i have seen look like they are in new construction, or garages or shops.
i'm wondering if it's possible to add a rocket mass heater to my existing home? it was built in 1950, the foundation sits on posts over a small crawlspace, no basement. the room i'd like the heater in has vintage red oak floors i refinished a few years ago.
my question is, are the rmh in general by nature of construction materials too heavy for this application? would it just fall right through the floor?
also, what's the permitting process like? i'm in portland, oregon, where you need to file a permit to take a pee.
in the center of the house, in the kitchen, there is a vermont castings encore wood stove, but unfortunately this only heats the kitchen and the second floor. the heat never makes it out to the living room, which is on the north side of the house with three exterior facing walls at east, north, and west. brrrr.
