Re: Need to replace corroded supply to radiator
Seems like the connection to the system is only a couple of inches from the bottom of the tank. That's plenty. The tank doesn't need to be completely dry, just mostly drained.
Re: Need to replace corroded supply to radiator
I don't think @EBEBRATT-Ed 's comment was so much about pex as to making sure you use a large enough diameter tube.
Regarding abandoning the compression tank, you'd need a pretty big expansion tank anyway to account for the large volume of water in your system. You may want to try draining it by splitting the union and putting a tee after your isolation valve with a drain valve there. Saves trying to cut out that plug.

Leaking boiler drain valves? As a band aid you can get some brass caps from your local hardware store or big box store and screw them on. Have your service provider replace them next time you have the annual maintenance performed.
I would also change how the gray expansion tank is installed. Sidewards tanks are more prone to failure. As someone who works on dozens of EK boilers I have to say that the way that one is installed is quite unusual.
Re: Viessmann cast iron boiler replacement.
John the CU3a can be piped like any old school boiler, if leaving the piping as is keeps costs down. It’s hard to imagine the owner paid large dough 30 years ago, and now wants to go on the cheap- give him the best!
It’s like pulling a G115 or an EK and installing a Smith or a Utica😀

Re: Beckett NX burner
Then you need a wind vane with a directional control switch. That way if the wind is blowing from the wrong direction, the burner will not be allowed to light off, until the wind changes to a more silky delicate direction.
Re: Steam Heating - Clogged Steam Pipe?
Put a level on the pipe to verify the pitch. It looks like it is pitched properly but the ceiling could be very much not level. Also look at what is happening after it goes through the ceiling and how it gets to the radiator. Another thing to try is to take the vent out altogether and see if maybe you have a bad new vent or something. And 1 pipe valves need to be either all the way open or all the way closed, if the valve is part way open the radiator will tend to fill with condensate and not heat.

I heard a drip. . . EK System 2000
Got home from work & notice a tray under my boiler is full of water and appears to be coming out of 2 pipes, photo attached. Wondering why and if anything easy I can do to resolve?
((Yes I will probably just call Village Oil but I always come here first to see if I can save a few bucks on an easy DIY fix))

I think it's important to establish if you can whether it ever worked properly.
Re: Pyrobloc
Yes Thank you I was just up there again and had a look. Pyrobar. Thank you for the reply.

Re: Difficulty in Properly Sizing Equipment - 2140 Sq Ft New Construction Spray Foam House
A few things I believe to be true, open for discussion:
- Hybrids are great if the fossil heating appliance is free (ie already installed). This boiler would not be free.
- The hybrids that make more sense are furnaces, not boilers, when installed in a new house so the ductwork can be used and less hardware is required.
- Hybrids are best when fuel 2 is cheap, unlike oil.
- Hybrids make great sense when budget options are used - combining a cheap furnace + cheap heat pump makes more sense to me than expensive furnace/boiler + expensive heat pump.
- Hybrids seem better matched to existing homes with high heat loads and other constraints (like 100A service). New houses benefit less, as install is easier and total available savings are lower.
- If radiant options are desired for subjective comfort, if the loads are small enough, electricity can make more sense than installing a boiler.
- When AC is already planned, concerns about refrigerant are immaterial. The refrigerant is coming either way.
- I typically think domestic hot water shouldn’t decide a heating and cooling system unless the situation is unique.
