it is a classic

$0
costs more for asbestos removal and then the weight then it’s worth!

Re: Oversized overtall chimney?
I have checked the specs on B-vent and not one tells us what temperature it has to be heated to vent. Chimneys are not mechanical devices. They are chases. You don't have to heat ductwork to get heat to flow. Can you oversize a steam pipe? look at some old chimneys on commercial buildings and their massive brick chimneys. Think they get heated before they vent. And why do chimneys vent in the summer when nothing operating?
Draft is a sign of combustion air. The higher the draft the more combustion air is available. The taller the chimney the higher the draft.
A neutral pressure point is also called a blast gas. Back in the 80's there was a product called a Thermizer that was a flue restrictor for residential and light commercial. They were very dangerous on drafthood equipment if you didn't understand venting and combustion air.
The chimney is too big was created by manufacters to make contractors look bad and then really pushed by liner companys.
Blast gate, barometric combined can do the trick.
And bring the firing rate back up some
Re: Failing pressure reducer valve?
If you have a pressure reducing valve or any other valve which functions as check valve between your water source and you how water heater, you must have an expansion tank on the hot water. It doesn't have to be that large, but it has to be there. Sounds as though your don't…

Re: Pricing on refurbished cast iron radiators
It's a rare customer who wants a cast radiator or a good sales person who can sell one. If someone is looking to head with water they are more likely to go with radiant or panel radiators. In some cases I've been able to sell a cast radiator for an entry way, you know to warm your mittens on. It's a small market.

Re: Frozen EVAP coil
Why does the coil require cleaning is the big question. That's not normal. That indicates poor air filtration, dirty ductwork, possibly high static pressure. Why has so many parts been replaced on this system? It sounds like the parts cannot has been fired at it but it still doesn't work.
In order to effectively help you we need static pressure measurements, saturation temperature measurements, indoor wet bulb, outdoor dry bulb temperature measurements. You know, the information a professional relies upon to diagnose a system properly. There's no reason so many parts should have been replaced and you still have a problem.
Re: Frozen EVAP coil
Airflow readings and psychrometer readings (dry/wet bulb, humidity, dew point) for supply/return would help.
Re: Oversized overtall chimney?
Quite the contrary, there is more than enough combustion air. That house is so leaky that there is more than enough combustion air. When the chimney starts to draft to its capacity, the air rushes into that boiler room and chimney from all over the home. installing a Fan-in-a-Can will only add more combustion air to the boiler room, it will not throttle the exhaust out the chimney. As a first step, sealing off the boiler room will accomplish the desired result. That may be easier said than done in that home. I would think that plugging off the chimney, and venting with a fan that can be adjusted to match the combustion air needs of the boiler as it is currently operating is a better use of that money. Finally a Combustion Air Inlet ducted to the boiler room would finish off the job, No need for motorized inlet and motorized exhaust. One motor should be enough.
Next step is to start the sealing up process, caulk, windows, insulation, and all things related to sealing up the conditioned space so those drafts stop altogether. Without this step, a windy winter day will have the same amount of draft thru the home as any chimney can cause.
