How does a line voltage thermostat work?

A line-voltage thermostat can control a single baseboard heater or several heaters wired together. The thermostat works by sensing the temperature of the room and controlling the amount of current that passes through the wires to the heater.Sep 6, 2021

Does Nest thermostat work with line voltage?

Nest thermostats usually work on systems that use 36 volts while baseboard heaters usually work on 120/240 volts. So, you will need to get a line voltage thermostat to control your baseboard heater.

What voltage do thermostats run on?

The most common type of voltage from a central heating and/or cooling system is 24 volts (24Vac). The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac). If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system.Nov 18, 2021

What is the advantage of using a line voltage thermostat over a low voltage thermostat?

These types of thermostats are popular because they use less power than a line voltage thermostat, averaging around 24 Volts. Low voltage thermostats can control virtually any kind of system from furnaces, boilers, radiant heat, air conditioning, heat pumps, or baseboard heaters.May 6, 2019
