    Variable Speed Injection Mixing For Hydronic Heating Systems The purpose of this section is to discuss the use of variable speed injection mixing to precisely transfer heat from the high temperature boiler (primary) loop to the lower temperature radiant (secondary) loop in hydronic heating systems. Various devices and plumbing arrangements can be used to accomplish this transfer.
  • Page 88 A permanent capacitor, impedance protected motor (no start switch) on the circulator is required. The maximum allowable amperage for this output is 2.2 amps, which limits the allowable circulator size to 1/6 HP. This type of system can use a small circulator to inject a high BTU input into a relatively large system flow.
