Reverse return

Joe_76

I was thinking of using a reverse return on some staple up between the basement and first floor. Heat loss is basically the same in all rooms. Being new to Hydronics I second guess myself( I spent years in high pressure industrial steam applications and part time managing family auto shop). Any thoughts or ideas.

What do you mean, do you want the same water temp at two different radiant manifolds at the same times?

The whole floor has the same supply temp, within 2F, I wanted to tee into the supply and use a reverse return so that all circuits are the same.

Reverse return is fine....

but in reality it only works as truly "self balancing" when the terminal devices (manifolds, tubing circuits, radiators, fan coils, what-have-you) have identical pressure drops.

I assume "self-balancing" is the goal here?

With only two terminations and assuming that the pressure drops are close enough to be called equal, direct return should work just as well and save some piping run, especially if you keep the main size going ahead the same size (like a header). In doing so, your last leg's pressure drop is so low it tends to compensate for the extra length it has to run.

Either way should be fine if the terminal pressure drops are close to equal- if not, neither matters and you should use balancing valves. Not the worst thing!
