10+ references for secondary return pipe size Its important for any exposed pipe work to be well insulated in-order to minimise any unwanted heat loss due. Am I right with 35mm hot pipe work or will 28 MM be enough. The secondary return will be in 28 MM from the cylinder and reduce down as required by the last bathroom. See also pipe and secondary return pipe size With water at temperature 50 oC the average specific heat loss from the pipe line is estimated to 30 Wm.
Gather information about the hot water recirculation system. The common piping length is quite short and can vary as between a close nipple and to an approximate maximum length of two foot.
On Mechanical Excessively high flow rates will impede these functions.
Should the secondary return follow this sizing and therefore returning to the cylinder in 22mm or can it be run in 15mm to the cylinder then up to 22mm just before the point of re-entry. On Mechanical Secondary Return Pipe Size |

Hydraulic separators must be properly sized to provide proper hydraulic air and dirt separation.
I intend to install locksheild valves on the returns at the outlets for balancing and fully insulate all pipe work. Secondary returns connect to your household water supply lines to recirculate hot water back to the water heater or point of use. Calculate the length of pipe used for the return line from the farthest fixture to the water heater. In a variable primary flow VPF. This requirement is driven by the need to reduce legionella bacteria but also reduces the risk of stagnation ensuring better water quality. This gives you a way of delivering the same water temperature to each secondary circuit.
