I already work with hot water heat, be it radiant "we're hillbilly here" or exterior wood burning furnaces. Would there be anything to gain from running a hot water coil off of a boiler into the furnace plenum and having that act as the primary heat source, maybe wire the gas valve in as emergency or second stage heat? or would it just add in an element of storage heat loss with no efficiency gain?
No announcement yet.
much like JC, i'm thinking
