Room heat transfer?
I live in a solar powered house which is heated by a single log burning stove which is situated in the main living area.
Is it possible for me to transfer heat to the colder rooms by simply putting ducting between the top sections of the adjoining walls (seeing that hot air travels to cold areas - in theory!) or will I have to use a fan? I am trying to use as little power as possible or ideally non at all.
Has anyone got any experience of this or know of any suitable solutions?
Many thanks in advance.
