Full Answer

Most low-voltage thermostats draw 24 volts of electricity, although some models can use as little as 6 volts or as much as 30 volts of electricity. The electricity used by the heating unit is drawn from a separate electrical connection.

As a result, they must be capable of handling 120 volts or 240 volts, so they typically have significantly thicker wiring.
