How old is your furnace and what is the efficientcy rating? Maybe time for a new one. Also, I read in Popular Mechanics that too big of a furnace will actually cost more to run than one that is the correct size for your house. Have an expert in the heating field perform an analysis of the heating needs of your house.

We have hot water radiators. When we bought the house in 1989 it had gravity hot water with a 300k btu boiler. Everything was broken because the house had been empty for a couple of years with temperatures at 20 below and the system had not been drained. So I did the heat calculations, replaced the the 300k but with a used 165k btu (slightly undersized), pumped the hot water, zoned the system and insulated. So the boiler could probably be replaced with a more efficent unit. Has anyone seen comparable reductions in heating bills to the increased efficiency of a boiler? I'm not in the mood for a bunch of plumbing work.
It has been somewhat colder here the past month. Since our kitchen is on the same zone as the apt, I'm going to try only heating our kitchen in the am, (and heating a bath with an oil electric radiator) and heating the rest of our downstairs living space in the pm, when the temperatures are warmer outside and see how much of a difference that makes.
