I used to have a big old house in New York that was heated with radiators (piped in gas for the boiler). After I got the first heating bill ($500) I put doors on the entranceways into the family room and used a woodstove that vented up a fireplace. I kept the thermostat at 60. Of couse going up to bed in the winter was a bugger. I used an electric blanket and wore a hat to bed. Later I used a propane heater in the family room, but it gets black soot all over the walls and ceiling, plus you are breathing that stuff. But, it used to be pretty cheap. I don’t know now. I think I used to use about 5 gallons for the weekend to heat one room.
Now I live in an old house in Maine but it’s much smaller. I recommend the first thing you do after you survive this winter is to insulate it as well as possible if it hasn’t been done already. Insulation in the walls (remove the siding and put up insulation); insulation in the attic; wrap any exposed pipes; put up good storms on all the windows (if you want to be authenic, you can use removable wooden storms which a carpenter can make). For now, you can put plastic clear insulation on the inside windows. You blow dry it and you can’t even see it. Don’t use the fireplaces pe se; most of the heat goes up the chimney. Have someone check out the chimney for soot and a lining, and if okay, use a woodstove/ or pellet stove vented up the chimney. A pellet stove and the pellets are expensive so this would be part of your long-term heating plans.
I use oil and wood. I have a combination of radiators and baseboard heating. I keep that at 65 degrees and use a wood stove downstairs to keep the kitchen and TV room warmer. I put up removable drapes with spring rods in the two doorways that lead to the hallway and other parts of the house I don’t use in the winter. I buy oil ahead in August (when its cheapest) and this year it was about 1200 for a thousand gallons, which is about what I use between Sept. and the end of May. I burn about 3 cords of wood at 125 a cord delivered.
what kind of heating system does the house have now? They were probably using the propane heaters because it was so expensive. But, you may be able to mitigate that with the insulation and good storms. From my experience, if you live in a really cold climate, you don’t use all the rooms in the winter unless you have a lot of money to spend on heating, so keep doors shut. It’s possible there is no heating system. Personally, I like oil because its the cheapest and I like radiators because they provide a nice, even heat. Natural gas prices are going no where but up, so I wouldn’t use that.
Your house is great, but if you are in a cold climate, you will have to adjust to living in a smaller space in the winter. But, that’s what so great about spring; you can open the doors and windows and enjoy!
I don’t know what it is about old houses. They just have this indefinable aura and compelling character. They are worth some extra work.
In New York I had a rule that I did not turn the heat on until Nov. 30 and it went off March 31, no matter what.
