Primary-secondary piping de-couples the boiler loop from the system loop making it independent from system loop pressure fluctuations associated with opening/closing of zone or 3-way valves. If you’re intent on building a primary/secondary system, be sure you construct it with closely spaced tees and a properly sized primary circulator. If you’re open to suggestions, consider the use of a hydraulic separator to achieve the benefits of a primary/secondary …

    Hydraulic separation of primary and separately pumped secondary circuit via a low loss header is recommended to avoid this. How does a low loss header work? By separating the two systems it allows boilers to operate at a constant flow rate in the primary circuit whilst flow rates and temperatures may vary in the secondary circuit. This avoids Primary Secondary Variable Primary. 12/1/2014 Primary Only Variable Flow Piping Systems 15 Variable Primary Only Piping layouts HydronicCondensing Boilers. Primary Only Variable Flow The Basics • The system pumps are used to provide flow through the boilers –No dedicated boiler pumps required! • Does not require mixing manifolds, hydraulic separators, or heat injection loops • The

    Hydraulic separation of primary and separately pumped secondary circuit via a low loss header is recommended to avoid this. How does a low loss header work? By separating the two systems it allows boilers to operate at a constant flow rate in the primary circuit whilst flow rates and temperatures may vary in the secondary circuit. This avoids o Employing primary-secondary piping. o Installation of a hydraulic separator between the boiler and the system loop. o Installation of a heat exchanger (for example, plate heat exchanger) between the boiler and the system loop. • For water heating installations, a storage tank provides the required decoupling.-

    An Idea For Chilled-Water Plants Whose Time Has Come… Variable-Primary-Flow Systems from the editor… Chilled-water systems that vary flow through chiller evaporators have caught the attention of engineers, contractors, building owners, and operators. Chiller manufacturers are increasingly receptive to this interest, thanks to ongoing HYDRAULIC CIRCUIT DESIGN AND ANALYSIS A Hydraulic circuit is a group of components such as pumps, actuators, and control valves so arranged that they will perform a useful task.
