Commercial heating - baffled by this one

[Ermintrude]

That on return back to headder? I wouldn't think so

Afraid not, that's in the line from the flow header to the centre port (arrow pointing up toward the valve from the flow)

 

[Ermintrude]

Not sure , could the bafoon have mixed up flow and return and swapped few bits around. Could pumps be flipped at flanges and csc rotated to make it work? Valves look a ballache to change out?

 

[Marty92]

I'm going to give it another look Thursday afternoon, altering any pipework will be a severe headache!

 

[Ermintrude]

Get a schematic

Your 3 ports are in the wrong place. Should be mixing flow and return to give you modulated temps.

UFH off that set up worries me.

Sit down, spend a few hours and sketch the bugger out zone by zone.

That was my thoughts too croppie, it's been running since 1989 though....

Its just possible that they are not mixing valves, they could be flow regulating valves, the point if them- I'm not sure but slower flow longer residence.

I'm not too concerned about high temperature to the floor as heat loss is massive before it even gets there! Not great but it is what it is!

I will be drawing for the O&M in anycase...

Love a thread that the big boys can get their teeth into.
Got you all thinking, great stuff.
