Re: Its hot in here 84deg but I am a lot hotter
Friedrich,
I hate the way business is done today. It was much better in the old days. Yes it took longer back then but with much less aggravation.
People paid attention back then and things got done.
Now with all the texts and e-mails it is so easy to communicate that people pay no attention.
First I had to get an appliance company to confirm my diagnosis. Done , no issue
Then he wanted a copy of the invoice where I purchased it. Done no issue. Is that all you need do you need anything else? No reply
Then he wanted a copy of the service report from the appliance company. Done no reply. Do you need anything else? No reply
Today, he needs pictures of the model and serial #s even though its on his service companies report. Why didn't he give me a list of what he needed in the first e-mail?. Its like pulling teeth. A lot of extra nonsense for nothing
They just look for a way to deny the warranty.
Plus I noticed on the name tag (which you have to pull out of the sleeve to see it) that the unit was made in CHINA.
I guess Friedrich didn't like Mexico.
Re: Vent Pipe For Boiler: How Far Into Masonry Chimney?
I ran into the same issue and ended up getting help from Emerson Pro Services to figure it out. Their tech explained that the liner should stop just a little past the chimney thimble, not pushed all the way in. Too far and it can cause turbulence or block flue gas flow. They also checked draft readings after install, which made a difference in performance and safety.

Re: Hartford Loop design origin
The Hartford Steam Boiler Inspection and Insurance Company (HSB) is a global specialty insurer and reinsurer headquartered in Hartford, Connecticut. Back in 1919 they invented the Hartford loop. By 1919 HSB got tired of paying for all those steam boiler failure claims and mandated all boilers that were insured by HSB to have the piping design they invented or they would not cover the boiler. HSB was founded in 1866 by members of a group known as the Polytechnic Club.
Re: Hartford Loop design origin
Well, I guess from a steam boiler point of view it keeps the boiler from draining in case the the return piping breaks low in the system. But, I meant it as a general concept.

Re: Hartford Loop design origin
it is just a trap with a vent to keep it from forming a syphon.

Re: Federal catalog/brochures
Just a curious question on why you are researching all these old boilers?
Standard procedure for steam is to get the radiation load and for HW to do a heat loss as many homes have been upgraded with insulation and windows.
Not a criticism of your efforts but wondering what the value of the information is?
Re: Baxi Luna
They offered me a parts account a couple years ago and had parts for really old units that a customer of mine was working on. This was several years ago I don't have emails left from them so prior to 2020. If they left the market they still have a number to call and try anyway! They still have reps too

Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
If you have staple up or suspended tube for the upper floor you may indeed need that higher SWT. Or carpeted floors drive up the SWT requirement.
A room by room load calc would tell. But you already know what it takes.
Although floor heat and forced air behave much differently, A large hydronic coil in the air handler could allow you some heating supplement at low SWT, 120 ish. And some cooling.
Is peak efficiency the main driver in your decisions?
