What is a Line Voltage Thermostat

A line voltage thermostat is also popularly known as an inline thermostat or a high voltage thermostat. Line voltage thermostats are used with systems that are powered by electricity. They are generally compatible with in-floor heating, ceiling and baseboard heaters, and forced fan heaters. A line voltage thermostat will most likely work if a place has one of these heating systems.

The main difference between a line or high voltage thermostat and a low voltage thermostat is that the former uses the direct mains voltage to power the heater while the latter burns fuels to generate power. And as you may have already guessed by now, another key difference is that line voltage thermostats function on high voltage, like 120 or 240 volts whereas the low voltage ones run on 24 volts.

Different Types of Line Voltage Thermostats

Two types of line voltage thermostats are available – single pole and double pole. The easiest way to determine the type is by checking the back panel of the existing thermostat. A single ole thermostat needs just two wires to connect to the service line of your heating system. It is important to note that despite being fully equipped to control the heating system, it can only turn the heater into the lowest setting to save energy and can’t be turned off. On the other hand, double pole line voltage thermostats require four wires to be connected to the primary circuit breaker. This allows it two functions on two different circuits. Thus, it can turn the power off from either of the circuits if required.

In simpler words, a double pole line voltage thermostat can work as a power button. Thus, it amounts to greater energy consumption as you can turn off the thermostat when it is not in use or not required. So it is always advisable to choose a double pole line voltage thermostat as it would help save more energy in the long run.

Features of Line Voltage Wifi Thermostat

Some features of a line voltage smart thermostat are:

  • Scheduling – These thermostats usually work multiple ones. So you can control the thermostats installed in different rooms. With the scheduling feature, you can adjust the settings to suit your requirements instead of having to change them every other time. Thus, it is quite convenient.
  • Remote access – Line voltage smart thermostats can be accessed remotely for your better ease of use. They come with an app through which you can control your thermostat and change the settings remotely, in an instant. So you could be out with friends, working, or even enjoying vacation but you can still avail the remote access facility to control your thermostat regardless of your geographical location.
  • Zoning – This is probably one of the favorite features of people having a line voltage smart thermostat. The zoning setting allows you to maintain different temperatures in different rooms. Hence, you can decrease the heating in a room that is not being used at the moment. This helps you save a lot of money by reducing energy consumption.

FAQs on Line Voltage Smart Thermostat

What is a line voltage smart thermostat?
