The Glitch & The Fix

A contractor connects an on/off water-to-water heat pump to a highly zoned radiant floor heating system.

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. 

This hydronic system was created to connect two gas-fired, cast-iron boilers to a low-temperature distribution system that supplies 10,000 ft. of 5/8-in. PEX tubing embedded in the floor slab.

An installer uses a four-way motorized mixing valve to interface between a conventional gas-fired cast-iron boiler and a low-temperature radiant panel system.

An installer decides to replace an old cast-iron boiler with a modern mod/con unit that has a 5:1 turndown ratio and integral outdoor reset control.

In an attempt to avoid purchasing what he considers “fancy valves,” an installer constructs the system shown with globe valves.

The hydronic system shown was intended to provide heat to a radiant floor slab and an indirect water heater.

A homeowner tells his installer that he wants a geothermal heat pump as well as a mod/con boiler to supply the radiant floor heating in his new home.

Over the last few years, we’ve discussed what hydraulic separators are for and how they should be installed.
