Re: Oversized overtall chimney?
No other criteria other than the house is still standing, and no dead people for a safe "successful" operating system?
I wonder what the combustion numbers are from downfiring an atmospheric boiler by 53%. Good thing there's excellent draft to get that CO outside where it belongs.

Hat's off to Canada!
Um…better keep that hat on.

Re: Oversized overtall chimney?
Add a makeup air duct someplace near the boiler with a damper that is interlocked to the boiler. If it is causing a lot of drafts in the house it doesn't have a good source of combustion air.

Re: Thin Tube Steam/Hot water in Barre VT
I have a home built in the late 1800's. Fieldstone foundation and a high water table. When I first moved in we'd get multiple leaks into the basement whenever it rained heavy. The previous homeowners poured a slab over the dirt floor and sloped it to drain to one corner of the basement.
There were no gutters and all of the water from the roof drained right next to the foundation and easily made its way inside. Over the years the soil eroded away and created a negative slope towards the foundation, making the problem even worse.
I fixed the soil grading issue and installed gutters making sure the downspout outlet was about 6ft from the house and draining away from the house.
Big improvement. The only time we ever get a hint of water down there is during extended torrential rainfall when the rain is going sideways and running down one side of the house. Even then it is barely a small puddle.
You can't waterproof a fieldstone foundation. The lime mortar needs to breath and moves with the earth. It will deteriorate rapidly if it is sealed over.
I'd avoid putting heavy plastic down on the dirt floor until the water issue is resolved. You will be sealing in the mud, muck and organic materials and it will get nasty under there.
Solve the water problem first. Make sure all rainfall finds its way as far from the foundation as possible and improve the grading to naturally drain runoff away from the house.
And make sure you don't have any sewer flowing back through the soil. I think one of those "Drain Cleaning" companies can do an inspection for you and locate any potential blockages or cracks. Many repairs can be made without digging up the sewer line.
Re: Combi Boiler water heater side... need a T&P
Not sure what code says where you are but I have always sold and installed a relief valve with tankless water heaters. As others said its not a T&P though, just a P lol.
I believe this cash acme valve is the one included with the caleffi tankless water heater service valve kits

Re: Serviceable Hand Held shower Head
Hi, Is it grit or hardness buildup? If the latter, maybe soaking the showerheads in vinegar and rinsing out might give them more life? I've done that in my hard water area with good results.

Re: Oversized overtall chimney?
Install a "fan in a can" near the boiler. You obviously don't have enough combustion air available for the boiler if your drafts increase when the boiler is running. The boiler needs and is looking for combustion air. With a "fan in a can" you can bring in somewhat controlled combustion air. Then invest in weatherization of your house. Having drafts thru windows,walls and, doors like that is very costly on your fuel bill. there are so many government programs to help with the cost.

Re: AC BTU Sizing question
As @mattmia2 said get the amps and model/ serial # off the compressor. If the nameplate is missing or can't be read take an amp reading on that unit or one of the same size. Ilandaire should be able to help you determine the size.
9k is probably more than you need
