I have a meeting on Wednesday with the facility people. Obviuosly the benefits would be no flow thru an offline boiler and the energy savings/boiler performance greatly increased. The thought of decoupling the boilers from the main loop did enter my mind but the boiler room is extremely tight and major repiping would be a major challenge and expense. This school was built 2 or 3 years ago and in relation to the hot water system the only issue I know about is lack of flow thru one of the boilers.
The only repiping taking place is going to be in the boiler room.

Reverse return piping has to do with the system piping, not the boiler piping. I find your use of the term reverse return piping in referring to boiler piping only, confusing. I don't know much about the rest of the system.Īre you planning on repiping the lines to your heating units? Just pipe the boilers primary/ seconday and use a mixing valve or injection system and it will work great. Each fan coil has it owns pump and it's own closely spaced tees. Primary/secondary piping with cross over mains works great on fan coils. They can help get you out of a problem when the system piping was not done correctly to begin with. I would not waste the money on circuit setter controls, in this instance. If you do your boiler room piping correctly, you will only have flow through each boiler when you want to have flow.
filters, balancing valves, averaging pitot tubes, orfice plates etc.) Dials may be for reading differential pressure, or reading flow directly, if ordered with a flow (square root) dial.If you are going to repipe these boilers as you say, then you would not need any circuit setters. Popular applications are balancing heating & cooling systems, checking pump performance, leakage, checking equipment for excessive pressure drop, (i.e. filters, balancing valves, averaging pitot tubes, orfice plates etc.) Model 831 test kit provides differential pressure ranges and accuracies as follows 0-5″ H2O to 0-9.9″ H2O ±5% / 0-10″ H2O to 0-400″ H2O ☓/2/3% full scale (ascending). Ideally suited for applications where differential pressures of 0-5” to 0-400” H2O may be encountered. Sensitive yet rugged medium duty diaphragm type portable test kit.
