@jeje59350 , read the article I linked to above. I'll bet it explains much about that system.
Re: Steam device to be identified
@jeje59350 , welcome to HeatingHelp. It looks like I'm going to have to visit Paris at some point.
A "boiler return trap" is basically a pressure-powered pump that comes into play if the steam pressure gets too high for condensate (water) to return to the boiler by gravity. These were pretty common in the States, and were used mostly on Vapor systems, which were 2-pipe steam systems that ran with a maximum pressure of 8 ounces (roughly 40 millibars) or so.
Where does that pipe go that comes down from the bottom of the device? Does it connect to the return line? Are there any check (one-way) valves in the piping under the device?

Re: Debate me Bro-3/8 inch pex 150 foot lenths AOK for high delta T radiant
fair question. dont have the tools on my cell but IIRC the pressure loss in 150' of 3/8 is still more than 300' of 1/2. so i was anticipating that i wouldnt amp up the circulator and the flow rate would be lower than target but i would be counting on high delta T to get the btus out and i have always 0referred that strategy even with 1/2 inch.
i can see from post below you share my affection dor 3/8. and they aint going broke selling it dor essentially the same price as 1/2.
and , to be fair, it is the pressure delivery at flow numbers on the plumbing side that warn folks off but i shower with 3/8 pex and im happy. i have to admit i chickened out running it on hot side to showers in 4 story building although i wanted to to cut the time to get hot to the shower head. if i would have had easier access to the chase i would have tried it .
so my occams razor take on the 'industry' is not even that they tell folks to do qhat is profitable to them but that they have given up on thinking about the best ways to so things and go the easy way for them. that includes the industry letting us down with regards to speaking out against bad regulation instead of just going along .

In the land of nearly reasonable electric rates….(thinking LI not so)…..an electric WH would seem good for an elderly couple.

Re: My three worst jobs sites. What are yours?
Aw c'mn guys. Sewage treatment plants aren't bad. I've worked several in my day, and first place you get used to the smell. Second place, personal hygiene is number one. Never washed my hands as often again. Third place, if the operator is any good at all, the place is really pretty clean… and we were really big on confined space protocols.
Oh just one more thing. Don't go for a swim…

Two slide rules that I still use. I find them as fast as opening a software or app.
The Rad Pad developed by Larry Drake. 1992!!
A concrete calculator.
I do have an extra RadPad somewhere if @archibald tuttle wants it

Re: Ruud Monel Water Heater
where is it leaking? unless it is a connection it is done. those have a gas valve that is questionable at best and i believe have the inlet and outlet tubes routed in such a way that you can't put a modern t& p valve on them.

Re: Why purge valve above boiler? Pumping Away.
you turn off the “service” valve , open the fast fill function
So water can only go around thru the system, it pushes air as it goes, up through the boiler to the “drain” valve purge point
With this method everything including the boiler gets purged from one point

Re: Repiping monoflo returns, how does this look?
This is what purging might look like in your Monoflo® system:
You will be able to get air out of the main pipe however the risers, especially to the second floor,
will be impossible to PURGE…. they must be VENTED.

You can still get manifolds with 1/2" sweat stubs, add your own pex adapter.
