I've just had a Triangle Tube Prestige 110 boiler installed. This is a modulated condensing boiler, and has an internal circulator pump for the hydronic loop.
What is the typical way to add zone to a boiler with an internal circulator? Would I add additional pumps outside the boiler, or just zone valves?
I'm an electrical engineer, so the control logic is easy for me, and I am a pretty good amateur plumber. So I'd like to do this part myself.
The old forced air system only served the first floor, and the second floor stayed pretty warm anyway. We thought we could get away with just heating the first floor for the time being, but it turns out that it's not the case with the new hydronic system.
