Wiring Basics for Residential Gas Boilers
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. To get from 120 V to 24 V we use a transformer.
Heat only 2-wire boiler/furnace installations for ecobee
Below is a diagram illustrating how the ecobee would be wired with the Common Maker and plug-in transformer in this scenario. Note: The R wire must go into RC instead of RH. This option is best for when a C (common) wire can't be identified at the furnace/boiler system for the FAST-STAT to connect to, or if you have T/T connections at your equipment.
Gas Boiler Controls Wiring & Application Guide
PDF filebrand boilers can do more, with less field wiring, and fewer aftermarket controls and components – improving the operation of both new and replacement boiler installations. These application drawings include detailed wiring diagrams, and set-up details, allowing installers to fully utilize the capability and
Nest - E, 2 Wire (heat only) Boiler With 24 Volt
The neutral wire from the transformer goes to the C terminal, and the white wire from my boiler is connected to the W terminal. When I powered the Nest-E back up everything seemed correct, it detected the equipment change, and the R, W and C terminals are lit up in the wiring diagram.

How to Wire a Thermostat for Your Boiler | DoItYourself
The transformer converts the 110-volt feed from the panel to a lower voltage that matches the thermostat wiring. Take the cover off the transformer and install the boiler thermostat wiring to the corresponding terminals in the transformer. The 100 volts powers the circulating pump and blower unit so that the transformer acts as a relay between
Steam Boiler to tstat wiring — Heating Help: The Wall
This makes things a lot less complicated, and runs less chance of confusing someone who is looking at the boiler's wiring diagram. Any decent relay with a 24-volt coil will do, and you can mount it in the cabinet near the transformer. Wire the "Normally Open" relay contacts to the boiler's thermostat leads.
