What can you tell me about this old Weil-Mclain E 5 B boiler?

Hugh Mason · October 30

My partner's new to her 1880s home is heated with a Weil-Mclain E-5-B boiler coupled with classic radiators. There's a Grundfos circulator in the system so it's obviously not a steam system at this point in its life . I see no information attached showing "last service" but the pressure tank is dated as of 10/6/16 and other updates appear to have occur back then. I see a screen that use to be attached to the bottom of an exhaust shroud with duct tape that's now drooping and no longer acting as a screen. There's also an uncovered hole in the exhaust vent that I would assume measurements might have once been taken.

What can you tell me about this boiler and its need for service?

What simple setback programmable thermostat would you recommend?

Thanks so much for you well earned advice!

Don't know what the duct tape is all about but it shouldn't be there and the flue pipe is falling apart with the joint in the second picture almost open. Really should not run this the way it is . Need a good tech to check it out (if one exists).

Post the city and check "find a contractor " on this site.

I'm not sure I want to see the rest of it. Find a reputable service company and get a full evaluation. Hope for the best, prepare for the worst. Even the thermostat is freaking me out.

That hole in the flue that's completely disconnected is a combustion test port. A port that shouldn't be there because the boiler has a draft hood.

@Hugh Mason , where are you located? We might know someone who can help……………….

I'm located in Lyons NY. It appears that all of the contractors in "find a contractor" are a long ways down state from us. I've called a local well regarded plumbing and heating business and took the first available appointment - Dec. 23rd.

Thanks for all the replies so far.
