Thanks in advance for taking the time to read this. I've been researching new furnaces thanks to an issue 2 days ago when we stopped getting hot water. My question is reagarding whether or not it's a better invenstment to replace or fix our old furnace (is it worth fixing?).
Quick specs: home is about 1400sq ft, 1-story ranch w/ basement, built 1955. New replacement Anderson windows, new siding, new roof in 2003 (just prior to us buying the place). Oil tank is a standard 275 gal. We live in New England (enough said on needing to stay warm!).
Furnace is a Crane model 70-122, not sure of age (no mfr date on label). Researched, unable to find any info. Got this from another post on this site:
"CRANE: Stopped making HVAC products in 1968. Furnace technology sold to Amana."
I'm guessing I've got at least a 38-year old furnace. It's oil-fired, steam=381 sq ft, water=106100 BTU's/hr. Burner capacity (light oil) is 1.10 gph. Min relief valve cap is 122 lbs/hr. Max working pressure: steam - 15psi, water 50psi.
Burner says CFR Oil Burner, MP 1998 model A1. Firing range .75-1.25 gph.
Our hot water runs off this too, so that's a factor to consider. Don't want to have to buy a separate tank if we don't have to. There's just a small expansion tank in-line now.
Okay, think that's it. (Bear with me, I'm an HO with no HVAC background.)
Long story short: lost hot water 2 days ago, checked furnace & verified it wouldn't stay lit (ignitor no good?). Had svc tech out & he replaced valve where oil feed comes in. Looked like solder was gone & valve cap was crammed back on originally. The furnace started working and did so for a couple hours. Now less than 24 hours later, the hot water is gone again and the furnace will not come on.
Does this even sound worth fixing, or are we setting ourselves up to be boned hard in the long run?
I've got pics, but they're large files - don't want to clog your site. Follow this link to my online photo album:
(Maybe you'll like the pics for your "shame" collection - I know it's ugly.)
The condition of the beast is not good - lots of rust & corrosion when we bought the place 2 years ago, and it hasn't gotten better. It's been on the to-do list for that long, pending the $ to do it.
Again, is this old thing worth fixing? What's it running at efficiency-wise? I know it's hard to tell without being there, but educated guesses will at least point me in the right direction.
Thanks again for taking the time to read and (hopefully) answer my questions!
