I'm trying to get a ballpark gas usage figure for my type of house based on your experience. Built in 1924, total masonary construction (brick with terra-cotta), plaster walls, original steel casement windows very good conditions, approx 2500 sq. ft., insulation: marginal at best, live in western Maryland
I've done some tune up on the boiler since I purchased this year, but I have no idea what the average usage should be. The system has a side arm heat exchanger with circulator suppling water to coils in wall fan unit which of course is controlled seperate from the steam system. From historic data from the gas company, some months (Dec, Jan, Fed) last year the usage was over 540 ccf.
I would like to get it down to 375 ccf at most. Is this a reasonable number to shoot for.
I plan to upgrade the insulation where I can in the attic and basement and put on proper storm doors. I want to do the insulation before I purchase a new boiler (old 50's model)or change to hot water. The windows will stay and I can't get any insulation in the outside walls.
Any thoughts would be appreciated!
