Hi all:

I have a 2600 sq ft 2 story home built in 1846. I also have cast iron
radiators in both floors, which are the primary heat source. We have an
oil
fired boiler which is five years old & 87% efficient att last measurement.
We would like to convert to radiant floor heat as we have total access to
the underside of the first floor. Anyone have experience/advice on
retrofit of a radiant heat system in older homes?

Randy,

No one can tell you how possible it is to install radiant unless they look
at it. Is your house heated with steam or hot water(radiators can be
either)? How well insulated is it? And so on and so forth.... Go to the
Wall and ask at http://forums.invision.net/Main.cfm?CFApp=2

IMO, you need to find someone that knows what they are doing. Go here and

Good luck!
