Re: AFG Parts Interchangeability
Motor, fan, coupling, primary, eye and lead, and the Igniter can be salvaged.
Replacing the fuel pump is not DIY, as pressure needs to be set, and that automatically calls for a combustion test. And a pressure setterer.
Also, if the primary is the Genisys, make sure it's a B. That's 7505B. If its an A on the end, no good with your application.

Re: skim port plug
After 20 years, I would bet it will have to be cut out. I wouldn't mess with it. You shouldn't have oil in a boiler after 20 years and skimming shouldn't be necessary unless you added lots of new piping…
Re: New House Floor Heating Help
Unfortunately that needs a complete repipe to work properly. That's a high temp boiler and will require some sort of mixing to reduce temp to the floor loops as well as to keep water re-entering the boiler return above 140*. Then the manifold situation as Ed mentioned (unless there is some magical blockage in the tee) isn't pushing anything into the floor loops anyway. Where are you located?

Re: New House Floor Heating Help
From what I can see that floor heat has no way to circulate water unless there is some sort of obstruction inside that manifold. the water will not go into the tubing loops because water will take the path of least resistance.
Re: White smoke from chimney
What was the temperature outside when you recorded that video?
There's not very much there, if it's cold enough out there's a good chance that's completely normal.

Re: Inside Heat-timer Varivalve Radiator Vents
Thank you for the kind words, Paul. These are so nicely made, it really bothered me that they keep failing.
Had to see what's going on.
Glue?? What the *** are they thinking?
Re: Lwco water supply shut off
I would recommend replacing that old galvanized water line , Cheaper then replacing feeders …

Re: Better to build pressure or short cycle gas boiler? Downfire?
Be very careful here: It may be "easy" to physically plug gas orifices, just be aware that without express written permission from the manufacturer, you're voiding any warranty. Worse yet, you are taking sole responsibility for assuring SAFE combustion. Are you trained? Qualified? Experienced? Mad Dog
Re: Help- Hot water baseboard heaters only warm to the touch
That installation has similar issues as the first one.
Same key things to fix here as I listed before and now you have to add the flipping the pumps over since they are not pumping in the proper direction to help the boiler work properly/efficiently.
Not major things that a decent person can't fix but unfortunately as others have suggested, the original installer and the person you recently hired are not the people to rely on to make the repairs. These things are so obvious they should have been spotted walking toward the boiler on their visit to your home.

Re: Wiring relay to cut heat call during DHW (combi boiler)
I think controlling the air handler fan via a strap-on aquastat on the air handler return pipe will solve this problem, as well as anything similar.
