Balancing Multi-Loop Domestic Hot Water Systems with

Dec 02, 2015 · One of the major headaches for engineers and contractors in todays complicated construction projects is properly balancing a multi-loop domestic hot water system (DHWS). Getting these systems properly balanced initially and having them stay balanced over the life of the building has, until now, been nearly an impossible job. CircuitSolver Domestic Hot Water Recirculation Balancing Domestic hot water recirculation (DHWR) systems need to be balanced in order to ensure that hot water is always available throughout the building on every floor, at every fixture. This is complicated because water flows in the path of least resistance and in open systems like these that can change constantly.

Recirculating Domestic Hot Water Systems

Domestic hot water is supplied from a tank-type water heater to the hot water trunk. It flows along the trunk piping and eventually into a riser that leads to the fixture with the demand. Once that demand stops, hot water flow also stops in all portions of the system.
