Common Question: If I replace my heat system, why should I use propane over oil?

Well, there are several reasons why you may or may not want to go with propane over oil. If you have an existing oil system and it needs to be replaced, there are a couple of factors that may cause you to decide you want to go with a propane system instead.

Propane out of the box, as far as the equipment and the installation, is probably going to be more expensive than staying with oil. But if your oil tank is not up to current code standards, there’s going to be an investment into bringing the oil tank up to code or replacing it. If your chimney is not currently code complaint, if it’s not lined, there’s an investment, a significant investment, inlining the chimney.

So you could be looking at $2500 to $3000 to line your chimney, anywhere from $500 to $2500 to bring your oil tank into compliance. And then, when you look at the differential cost of upgrading to a propane system, it may be advantageous for you to consider that.

Also, propane is going to be cleaner, it’s going to operate at a higher efficiency percentage, and you don’t have to have a tank in your basement, which can free up space and alleviate the liability of storing that hazardous fuel in your home.
