Looking for some options for an upcoming project. The details, It is an old house, 285 years young, a saltbox with about 2000 sf living area. Has an old steam system that has been non operational for more than 4 years. There was a freeze up when the house was vacant. Of course everything is wrapped in asbestos which will be removed proffessionally. air conditioning is somewhat important but ducts will be difficult as the house is primarily wood sheathed and exposed beams. We can get a home run up to the second and even the little room on the third floor. We have been thinking of the Unico system for that but am also considering radiant for the first floor. My first concern with radiant is the heat loss which I have not had calculated yet. We will need to consider the source for domestic water also. Another option is to use the old cast radiators over again in which case it may be better to encapsulate the pipe insulation rather than remove that. I think the existing Burnham boiler belongs in their hall of fame! Any thoughts entertained.
