Our American Standard G-2 hot water boiler was installed in 1956 or 57. It has kicked on each fall and seen us through every winter until . . . the great polar vortex of 2019! The motor was replaced 3 times and the pump 1 time in the 60+ years. A new water value, safety value/relief valve & backflow preventer was installed in 1969 and again in September, 2018. That totally eliminated air in the system and the boiler was running smoother than ever.
Either the Honey Gas Valve V808 1184 1 or the Thermac Co Pressure Valve failed or is failing. The gas pressure for the flame is far less than normal. It is keeping the house toasty warm in the post vortex 40 degree weather, . . . but . . .
1. Would anyone replace those parts and hope for another 10-20 years (I can't seem to find any replacement parts on google!) or is the only solution a new boiler?
2. What are the best made boilers these days? Hot water heat in radiators from 1900. (Tag says: input 180000s BTU Ouput 144000 BTUs)
3. I am guessing a new boiler with installation in Chicago $. Is that in the ballpark? I took over the maintenance from my father in c. 1970 so with the savings on maintenance, I can bite the bullet and pay for a HVAC professional . . . I was hoping I could wait until summer . . . but that might not be possible.
Thanks for your good counsel & advice!
