I have a similar sized house and also no wall insulation (do have attic insulation). Gas radiator heat. Our bill is projected to be $600.

So you’re not alone. When I compare our gas usage to last year, we’re actually using a bit less, but rates have gone up a lot. We also keep it set to ~64, but with as cold as it was recently, the boiler was basically running nonstop.

Have a few older windows and some door seals that should be replaced, but still, $600+ in a month is crazy. I’m also considering the budget billing that someone else mentioned, but wish I would have done that sooner

I’ve got a one car garage in the Lauraville area you’re welcome to use as well. It’s small but I work on my E30 in there and have enough room generally. Let me know, always happy to help out a fellow car person
