The system was originally designed for a circualtor that would adjust to demand from individual loop flows in the system.
The system is for a fairly large square footage. A good part of the area that can be heated is not. Only about 40% is actually heated (excludes basement, garage, and a potential greenhouse).
The solution was to be a pump smart enough to deal with this situation. I tried a brand name pump. It was the same basic pump, but "variable". For whatever reason the pump with the variable speed controller was hideously noisy (vs silent for the fixed speed). I bought equipment to control a pump, but it was also an expensive disaster. My fault. I thought the contractor understood what I was saying. Turned out the implementation was above his pay grade.
There was a very interesting pump that appeared to be perfect for the application, but they only came in "REALLY BIG".
What I need is a pump in the loop feeding the various zones that adjusts the pressure across the loop on a real time basis. This will cause a stable pressure to be presented to each of the zone valves. This would minimize noises and stabilize flow rated in each zone circuit.
This approach would also require a device between the input and return of the loop piping to constrain the pressure across the loop to allow the pump to control it.
If anyone has suggestions for products to implement this, I would appreciate some ideas for components. Or discussions of why it will or will not work.
