Over the last few years, hydraulic separators have been gaining popularity in the North American hydronics market. Eager to keep up with this new technology, an installer decides to install a hydraulic separator between a boiler and distribution system.
Over the last few years, hydraulic separators have been gaining popularity in the North American hydronics market. They provide an alternative to closely spaced tees when the task is to isolate the pressure dynamics of one hydronic circuit from those of another, connected circuit.
Eager to keep up with this new technology, an installer decides to install a hydraulic separator between a boiler and distribution system as shown in the figure below. This system serves space-heating loads and a prioritized indirect water heater.
Look over the drawing and see if you can spot any errors, as well as methods of achieving the desired operation with simpler piping and less hardware.
