Insulating an OLD House-Oil Costs

[dpg]

Maybe I'm wrong but I do not considor a 15 year old furnace to be very old. As stated earlier I'd tackle other tasks like insulation and buttoning up the outside if it warrants. Sure there's newer and more efficient furnaces out there however a furnace isn't a throw out every couple year commodity. Mine in Mass is 31 years old (fingers crossed as I say it.)
