If you really want to save money don't heat as much of your house as many degrees.
If you want to save money and be warm you might be able to cut your heating bills in half using coal and an incinerator. (I don't know where you live). If you have a kid you can make it their chore (it is a chore). I love my incinerator and it loves old boots and used motor oil.
Hope this helps, William
PS: Natural gas is in fact cheaper. Oil probably was for a time but that time has passed.
Which one is the lowest price to heat a home in New England this week? Say oil is at 2.50 a gallon. Assume identical efficiency of 90 percent on each boiler. And say a therm of gas 100 CCF is $1.25
We are replacing a boiler and of course each side says something different.
Oil boilers efficiencies are in the low 80% range. You can buy gas boilers that run in the high 90% range. Buderus for example, has one, depending on its use, that runs 98-99% efficient!

negative for oil is you really need to do a though cleaning of the heat exchanger every year or two to maintain efficiency, (pretty nobody keeps up with this!). Natural gas boilers burn relatively clean compared to oil, so the heat exchanger never gets dirty so you save $$ on service. In my area oil has always been higher to use, 2-3 times higher when you figure efficiencies. Greg
$2.50 per gallon oil at 80% efficiency gives you a cost of $22.53 per million BTU $1.25 per therm of NG at 95% efficiency gives you a cost of $12.74 per million BTU Greg
This, using your numbers, shows gas being far cheaper, but the price of gas is going to go much higher soon. If it his $1.75 to $1.90 as predicted, it would be about even. BTW, it makes coal look like a good option.
Buderus makes a great oil boiler, too. If you want to pay a premium price for it! But I think it's only rated at 89% (if THAT much). Even with the efficiency ratings at 85% for oil and 95% for gas (propane. We don't have natural gas in these parts), I think that you still get more heat for the money out of oil. Even our local electric co-op says that. It's close, but I think oil still edges out. I don't say that because I work for an oil company (I do!). I just go by what the reports say (and, no, I don't have any of those reports right here in front of me).
Even though I work for an oil company, I will say this: We have commercial (on radio and TV) saying "Today's oil furnaces burn 99% clean!" BULLSH*T!! They may burn clean when they are first tuned up, but there are so many variables that can CHANGE that over time. Sure, there are ones that burn good all year long and you have no problem with them. But if you let them go and don't have them service at least annually, you are just asking for trouble.
I moved from a house with a forced-air oil furnace to a house with a heat pump and I couldn't be happier. Now, I don't know if i would want one in New England. But where I live, it works and I am happy with it.
I have customers ask me all the time: "If you were going to build a house, what kind of heat would you put in it?"
To which I reply: "I would build a house where I wouldn't NEED heat!!"
Our house had an oil furnace in it when we bought it. I asked the seller when the last time it was served, last season was his answer. I pulled the gun out of it, opened the heat exchanger and removed darned near a five gallon pail of sot from the heat exchanger. Then I pulled the blower and removed the extra dog that was lost in the blower wheel. The inside of the blower wheel looked like it was wrapped with felt it was so full of dog hair! Not just the cups, but covered on the inside! I found a couple small cracks in the heat exchanger so it was due for replacement anyway. I ran it until January and put in a 90+ natural gas unit. My heated bills dropped by
40% a year after that!
That was fifteen years ago before I got into HVAC. Today I am pulling out the old 90+ York, and replacing it with a Ruud modulating furnace. The York was a bit oversized, (2 times over!), so I hope to drop the gas usage a bit more, also the mod should trim a bit off the electric bill as we run the blower pretty much 24/7. The Ruud is a 60K and on low fire it will run 24K BTU instead of the 80K BTU of the York.
If I was going to build new and plan on staying I would go super insulated, and geothermal heat pump. Cheap to run, but installation will bite you! in this old rambler I live in it don't pay to get too crazy. Greg
