I am renovating a 1915 bungalow. The house currently has electric baseboard heat (expensive and ugly) and I would like to rip that out and put in old-style hot water radiators, with a central boiler for the water heat source. I have even thought of going to a salvage yard to get old radiators, cleaning them, and using a new boiler. First I would ask if this seems a reasonable idea. Then, I would ask how to clean out old radiators (remove scale, deposits, rust, etc) and keep them free of new deposits buildup during use. Any comments?
