Boilers piped in parallel
WebThe common pipe. The key to all primary/second-ary applications is the use of a common pipe, which interconnects the primary and secondary circuits. The length of this pipe should be kept very short in order to keep the pressure drop low, and the supply and return tees to the secondary circuit should be a maximum of four pipe diameters apart.
