The thermostat is the brain behind your furnace or boiler operating properly, and these little guys come in a variety of different types. Some have mercury switches inside, some use mechanical switches, some are digital, and programmable electronic models will do everything except wake you up in the morning!

With Anatomy of the Furnace Thermostat you'll learn the differences between these thermostat types, how they work and see if you want to upgrade. And learn how to troubleshoot and fix a faulty thermostat too!

And if you want to replace your old thermostat or decide to get an electronic model to save energy and money this heating season, then go ahead and do it because installing a thermostat is easy and I'll show you how.

This is great information and help for replacing the thermostat. I’ve had to get mine replaced twice in the past 3 years. I’ve used the company Boiler Repair in the past and they did a great job on it.

Good advice. Don’t be ripped off by unregistered boiler repair men
