Can someone please explain the meaning and function of different bits
of a central heating system:
-Is there a difference between a by-pass and an automatic by-pass
valve?
-Do all new boilers turn off if the return is the same as the water
going out (which I presume is what would happen with a by-pass)?
-If not, is there such a thing as a flow switch to turn the system off
in conjunction with the by-pass?
