Re: Single Pipe Steam Boiler Replacement & Piping (Unusual header?) Advice for Amateur
The near boiler piping is very wrong. it might happen to work ok now but it should be done correctly with the new boiler.
The header should be in the order of:
risers from boiler
risers from header to mains
equalizer
The header and risers from boiler size should be at minimum the size specified in the manual
Each main should connect separately to the header. If a main is counterflow it needs a drip down to below the water line before it connects to the header. each drip needs to have its own return connection below the water line.
The header shouldn't reduce in size on the horizontal so it doesn't trap water.
Run away from anyone that says to put in a boiler bigger than the connected edr. The nameplate edr has an extra 30% pickup factor subtracted from it so it is probably oversized a bit even if it matches the nameplate. Do not use anyone that suggests you should go bigger than the connected edr beyond what is the closest size.
If you have a main that is filling from a return, you have to figure out why that is possible, most likely returns from different mains that are connected above the water line. The returns from different mains must connect together below the water line. The most common reason for this is that a connection that was below the water line became above the water line when a boiler with a lower water line was installed. Also possible that whoever installed that boiler didn't understand why returns at the boiler needed to drop below the water line before connecting. The steam from the other main will come in to the main at the vent and close it, preventing the main from venting properly. It will eventually vent through the radiators but it will be slow to heat.
Your near boiler piping looks like they just hooked up whatever was closest wherever they could and didn't know what they are doing.

Re: Hydronic air handler not heating
UPDATE- @mattmia2 It worked out. Connected a hose to the valve on furnace side and turned it ON. It removed all the air from the coils. Heat is back On.
Thank you so much for your responses!

Re: Hydronic air handler not heating
depends on what isolation valves and boiler drains you have. you need to isolate so the flow from the municipal supply goes through the coil and out a drain. Ideally they would have put those near the domestic water heater so you can purge the coil without actually going to it.

Re: Remove PTAC unit for servicing
I got an AC tech (who I trust - he did work for me in the past) to quote me to clean the units.
He quoted me a fair price to clean on site. He's going to lay down a protective tarp, pull the units, spray the condenser and evaporator coils with appropriate cleaners and wash off with water.
For 25% more hes going to take the units to his shop, power wash off the dirt & grim. Clean the condenser and evaporator coils with appropriate cleaners and rinse off with water. Vacuum out the blower wheel. Return the units in the evening.
Seems like a no brainer to have him take it to his shop.

WAIT! If memory serves, I thought it was the tariffed countries that paid the fees, Not consumers?

Re: Replace a Munchkin boiler before it fails, or keep it going?
assume a number of 37 btu \ sq.ft, as the high side if what a radiant floor could transfer
3600x 27=97,200 btu/ hr
Ideally a heat load would give you a better number to size to
So if my guesstimate is even close ? A 125- 150k boiler should cover it
While mod cons have a wide turndown, size it as close as possible for a long healthy life

Re: "Yelp"/ angi list for contractors.
The most uncomfortable part of running a Plumbing & Heating business is discussing $$ & payments. Get it out of the way as fast as possible ...a ball park range is better than nothing. This, especially holds true with relatives, friends & people you know. Get it out of the way and be 100% clear, cogent & concise.
If there's any waffling or trifling, it's better you both know BEFORE a piece of pipe is purchased or installed. Worst case, we shake hands and go our separate ways. Mad Dog
