Counter flow system

Hermann

would like a diagram of the best way to pipe in a boiler on a counter flow main where the main goes left and right of the boiler I have pictures of the piping going just one direction but nothing on piping going two directions

Counterflow

here is an example of counterflow piping in this thread.  The steam goes up the main and the condensate returns in the same main, the condensate is diverted down to a typical wet return.

Just finishing up this very type of system tomorrow.

It is simply the same as in the link but a mirror image for the other supply pipe connecting on its own to the drop header. I increase the header size by at least one pipe size for such a system as compared to minimum set by manufacturer.
