Why do I need an in-floor thermostat?

An in-floor thermostat regulates the temperature of your electric radiant floor heating system. Unlike thermostats for HVAC systems or other heating systems, in-floor thermostats are designed to handle line voltage (either 120V or 240V). Also, in-floor thermostats have features that other thermostats don't have, such as Class A GFCI's, floor sensors, and air-sensing modes
