Application For Small Smart Circulators In Hydronic

Oct 29, 2003 · The ability of a small smart circulator to intelligently protect a conventional boiler from sustained flue gas condensation and thermal shock is a key benefit in systems that interface conventional boilers with low temperature/high mass loads. The electrical energy consumption of small circulators is reduced by running them at reduced speed.

Wiring Basics for Residential Gas Boilers - ACHR News

Oct 10, 2000 · The load is now a boiler. (See Figure 4, page 20.) This wiring diagram shows 120 V coming from L1 of a circuit breaker, through a switch, powering a boiler control and returning through L2, back to the neutral bar of the circuit breaker box. This is fine if the boiler is 120 V. However, most gas boilers you will be working on have 24-V controls.
