I am about to begin re-plumbing my OWB and my house which I will cover under another thread for entertainment purposes, plus to show what happens if you don't properly research and plan things.
I've been studying boiler system plans and I have a few questions.
-As far as a zone valve is concerned, I only need to get one with the same size inlet as the pipe on the line it is feeding correct?
-I believe I am understanding that zone valves can be purchased normally open or closed. I know what that means, but I would want to have normally closed correct so it only opens when the zone is calling for heat?
-I see a lot of plans with individual circ pumps on each zone line. Is this for better control within each zone so head pressures remain more constant?
Thank you in advance.
