I am buying a house in MA with a partially finished second floor.
On the first floor is a oil fired hot water system. The pipes for the hot
water heat have been brought up to the unfinished second floor bath. What I
would like to do is bring the heat into an exchanger in the attic and heat
the second floor with hot air on a separate zone. The walls and trim are
finished on the second floor except for the closet and the second floor
bath (why, I do not know). I would like to do a minimum of destruction and
reconstruction. Using the attic space and doing forced hot air and returns
in each bedroom and the bath would require minimal patching and repainting
(and a central AC option). Trying to get baseboard heat to these rooms is
too destructive (but maybe unavoidable).
(hopeful but realistic)
