In Reply to: New update and question on sub loop posted by Ruth on August 04, 2006 at 15:38:52:
What is exactly the reason for the bypass(sub loop)? Is it really necessary? Thanks.
The boiler subloop assures that no matter what zone is closed, The flow through the boiler is the same, as explained in the site reference in the post above.
It is necessary when the factory engineers advise it and especially when there are multiple zones. Of course in an analogy where the doctor (factory engineer) is going to do the operation, the nurse's aid (plumber) might not think it is necessary.
