When you turn up your heat on the thermostat, the thermometer coil and mercury switch tip to the left, which starts the heater.

A heat anticipator shuts off a heating system before the ideal temperature is reached, allowing time for the heat in other areas of the home to reach the thermostat's thermometer.

The G wire connects to the relay that turns the fan on and off. Without the fan, hot and cold air would not be circulated inside your home.

Digital thermostats use a thermistor to calculate temperature, which it does by measuring electrical resistance.

The biggest difference between the two is that a digital thermostat lets you program temperature settings for different times of the day, which can save you big bucks on energy costs.

According to the U.S. Department of Energy, you could save up to 30 percent on energy costs by using a zoning system. Over several months and years, this can add up to considerable savings!

The U.S. Department of Energy's Innovation and Invention Program funded the development of a damper system that can be installed and used with existing mechanical home thermostats. It can serve a similar function as zoning, which is typically used only with modern digital thermostats.

Talking thermostats may seem like a frivolous add-on, but they can actually save you money and stress. Talking thermostats alert you when they need servicing.
