I'm having some issues with my current steam heating system. I'd rather get it replaced with a whole new system, either forced hot water or forced air. The house was built in 1916, so I'd have to do mini-ducts if I went forced air (thin walls). I plan on feeding the system with the gas line I already have coming in.
I'm sure there will be some floor and wall tearing, but I'm curious to know how much, and should I really not put too much weight on this aspect.
The annoying part is, the previous owners did a renovation in 2009 but left the old steam system. Not that I have anything against steam but they didn't replace any of the pipes, values, air vents or radiators.
