I own a home older than dirt ( not really just 1932) and live in Maine. I think the boiler might be older than me though. Heats fine - just not that efficient and well Maine is CoLd.Maine has a program that provides low interest loans (3%) to replace inefficient boilers, etc.. anything related to energy or structure...Anyone know which boilers are good, what approx cost of replacing etc.. I have old cast iron radiators in each room of house. I have Natural Gas. My water is also heated this way. I could potentially (according to the charts) cut my energy costs from 4,000 a year to 2,400.
Your best bet is to contact some local companies and ask them for quotes. Just make sure they don't charge you for them. If the system is fine and you're just strictly replacing the boiler, you won't be running into much in the way of labor costs as it should be a fairly simple swap. While these companies are in your home, you can talk to them about different brands, etc. Try to get these quotes now before those companies get busy in the cold weather. I'm sorry I can't give any specifics on the brand of boiler. Good luck to you.
