How is a boiler thermostat wired?
There are two common types of wiring systems used in boiler thermostats: two-wire and three-wire systems. In a two-wire system, there are only two wires connected to the thermostat: one for power (usually red) and one for control (usually white).

Do you need a special thermostat for a boiler?
No, you can't use just any thermostat with a boiler; you need one specifically compatible with boiler/hydronic heating systems, checking for voltage (like 24V) and wiring needs (like a C-wire for smart models) to ensure proper function and safety, as boilers use different signals than forced-air systems. Modern smart thermostats often work with newer boilers but older systems or specific features (like zoning) require careful compatibility checks, potentially needing professional installation or a C-wire adapter.

Can a thermostat be hardwired?
Once hard-wired, the Common wire provides a continuous 24-volt power supply to the thermostat, ensuring your AC runs smoothly with no interruptions you typically find with batteries. (Note to self – no more searching for batteries.)
