I need to replace my gas hot water boiler/furnace?
Concern by tommy lampini: I need to have to change my gas sizzling water boiler/furnace?
I want to replace my gas hot h2o boiler/furnace (which is 45 a long time previous) in my parent’s house. The contractor who I hired to mild the pilot explained it’s a CO hazard to have a forty five yr outdated gas furnace and that the heat exchanger possibly has leaks.
How significantly am I looking at spending?

I would get a second opinion. It sounds like this guy is givin you the scare tactic. call your local utility and they will perform a carbon monoxide test. let this gut show you in writing the numbers of any test he performed on your boiler before you go thru the hassle of a new system
Depends on the Btu size.
Make sure the contractor does a Manual J (sizing calculations)… most don’t do it cause it’s a pain in the butt; most just put in one size bigger than the one they pull out.
The Man. J takes everything about your house into consideration… insulation, site orientation, building leakiness, type of windows and doors, etc.
The other thing to look for is, after the new boiler is installed, watch for water leaks at your copper fittings.
Not to say it’s not a good idea to replace a 45 yr. old unit, cause it’ll probably pay for itself quickly in fuel savings based on efficiency alone, but make sure he shows you the crack in the old heat exchanger (and don’t let him create one pulling the old boiler out, a common trick).
Some of those old boilers with their cast iron heat exchangers are still just fine — as far as safety goes. Your gas utility likely has a free or low cost service where they will test for fume leaks. The problem is that they get so gummed up that they can be as little as 40% efficient in their use of fuel.
We just replaced a 35 year old boiler in an 18-suite apartment building for efficiency reasons. We did not go for a “high efficiency” boiler at a cost of $ 20,000 but chose a “medium efficiency” 82% efficient RBI boiler at half that cost and have calculated that, even if natural gas remains at $ 7.50/gigajoule, we will be money ahead midway through the 7th winter.
Be sure to shop around though. We found differences of over 35% in quotes for installations of boilers with nearly identical specifications and uniformly excellent reputations.
