Hi, everyone, and thanks for your consideration. Since I was a small child I have lived in a home now over 100 years old. It has steam radiators, some of which I am told were not made later than 110 years ago. I can post pictures if wanted. I would very much like to keep those in the living room, dining room, and possibly the bedrooms, as they add to the charm and character of the house and figure in childhood memories. The kitchen one is a more plain style and if there is a better way to heat the kitchen as well as or better than the radiator, I am okay with that. In the dining room, living room, and kitchen, the radiators are large and give good heat. The house could even be made pleasant in winter if less drafty. (I wear a hat or at least a headband inside at all times from about November through March!) In the bedrooms the radiators are small and give little to no heat. One room is bearable when bundled up and the other requires a space heater even when in bed. At one point the whole system was heated with coal. There is a former coal cellar with the chute still in place and a few ancient lumps still around. We've been through a couple of coal oil furnaces. The oil is delivered into a tank and the pipe is inconveniently placed in the yard, a tripping hazard and a nuisance to work around. When the line became plugged, it was strung across the basement floor, causing other unpleasant issues. I would like to see the WHOLE SORRY MESS gone! What I would like to know is: 1. Can we leave the radiators which work well in place but run them by some other means than coal oil? 2. Can we have one system in those rooms and another in other rooms, or does all heating have to be through one system? In other words, if the bedrooms and one bathroom are barely heated and back rooms (one of which has plumbing, so a space heater must be turned on and constantly checked all winter) and the basement rooms have little or no heat, and say anyone wants to add rooms (such as upstairs) and the radiators barely keep the main floor at temperatures compatible with life, should some other system be installed in the other rooms? Can this be done without sacrificing the radiators in the rooms in which I do enjoy them? 3. If ALL radiators for any reason MUST GO, are old radiators good for anything? They take up space and weigh a ton, but some of the old ones are really pretty! Thanks for any help on this.
