two pipe heating system for two story house (with attachment)

In my previous post I forgot to attach a drawing, sorry about this.



Hello Experts,







I wonder if I follow the diagram (attached) I draw myself, the heating

system is going to work? I am talking about two pipe system







I have two floors that I want to make as a one zone. I want to bring

both pipes (incoming with hot water and return - cold water) close to

each other in the middle of the house since I have a wall in the middle

where I can hide them. I want to make branches to the left and right

side of the house on each floor.



I am also thinking about using PEX pipes for the entire installation. Not sure if I can do this.







  I would appreciate if you can review it and reply.









Thank you,



Vad

    Sorry, am I completely wrong that I get no replies?

         I am trying to understand if it is going to work or not. This stuff is new for me.



    Thank you,

    Vad

    like nothing

    I've ever seen before, and at first glance looks like yer doin' it rong. The longer I'm looking at it the more flabbergasted I'm getting.

    I would be doing each floor as a zone, unless you are living in the 1940's. In a cape.

    I would be running a simple series loop for each floor per apt or whatever, zoning it, and calling it good.

    Pex is fine, but use composite Pex..Pex-Al-Pex (PAP).

    Looks like simple,,,

    Direct supply & return to me,,,, lots of those around.

    For starters, this arrangement would not work without TRVs on every rad.

    Thank you Dave, Bob and others. I was very buisy and could not reply in time

    The reason I was thinking about 2 pipe distribution is as yiu understand to keep all baseboard with the same temperature.

     I remind that I have 2 stories 2 family house in NY  (1700 sqf  + Basement).

    I am planning to have 2 zones - 1 for 1st and 2nd floors and one for the basement.

    If you think 2 pipe system is overkill, what about to have 2 loops per floor? I think it calls split loop.

        Would you recommend this setup?

         Looks like it is less complicated. I include an attachment with the new diagram.

    With this setup, do I need TRVs or anything like this?

    I am not sure if part of the diagram related to the baseboard in the basement is correct since basement is going to be in a separate zone. Maybe I should not attach basement radiators to the main pipes?



         I appreciate your feedback

    Reverse Return

    I would go with a reverse return setup. That will clear most of your distribution issues. The only extra parts you may need are balancing valves. And you can zone each floor separately if you want.
