We recently purchased an 1850's era, 2 story house in SC. It's about 5,000 square feet, and still has an intact boiler/radiator heating system. I have no idea when it was last used, if it works, or if it would be a good idea to try to use it. We are about to start some renovations, and don't want to demo it out if it could be utilized efficiently. That type of system is not common in this area, and I'm having trouble finding someone who even knows what it is. Any suggestions? Thanks!
