Heating with wood is a science unto itself. Good wood is essential. Hardwoods like oak, maple, and hickory are best and soft woods like pine should be avoided as they cause creosote to build up in the chimney and cause of many house fires. For two years I was logging Hickory and that is all I burned for firewood as I got all the "Tops" for free. A single log would burn all night leaving a nice bed of coals in the morning for a restart. The problem with heating with wood is you have to buy the wood or posses the tools to harvest it. After many years of dealing with 4 wheel drive vehicles and chain saws when I added up all the expenses I found firewood even for free ain't cheap especially if you get injured.
I now heat with propane exclusively my total yearly heating bill is usually about $500. I have wall mounted vented heaters that seem to work quite well. They do not require electricity to work therefor supply heat even in the case of a power outage.
I understand that oil heating technology has changed a lot in recent years. Many manufacturers boast of over 90% combustion efficiency and require no chimney as they are vented with a PVC pipe. Regardless the installation of an oil fired system is expensive requiring a tank, fuel line, and delivery ducts etc. Oil does have the advantage of 135,000 btu's/gal. Oil fired systems require electricity to work
One thing to understand about electric usage is that every watt of electricity you use becomes heat in the end. So for example when your using electric heat turning off the lights to save electricity is of no value because the lights produce heat also. No electricity no heat.
I have recently done a cost comparison on heating Fire Wood is the most expensive if you add in the costs for a broken leg. Propane, Oil and Electric are all quite close to each other. Propane for example presently costs 2.48/gal . A gallon of propane contains about 90,000 btu's of energy of which only about 80% is delivered as heat to the house due to combustion inefficiencies. So lets say there is 70,000 btu delivered heat. Electric heat on the other hand achieves almost 100% conversion from energy to heat and to purchase an equivalent amount of heat would cost about $2.80. Therefor electric is a good heating source when propane costs go over 2.80 per gal. I have paid over $4/gal.
