Close on the mercy thermostat. Mercury bulb is attached to a bimetallic spring. The spring expands or contracts with temperature changes in the room. As temp drops, the mercury gets tipped to one end of the bulb where it closes the circuit. They never go bad, they are just not very accurate. They can be off by 5-8 degrees. Digital are significantly more accurate.
Cool thanks for the info. It not being very accurate explains why it was always so hard to find a happy spot for it. The digital one has been a lot more efficient in keeping the house comfortable. I really like I can program it for when I'm away from the house vs at home.

My grandpas house had one and a church i went to had 6 of them all synced. Was always fascinated by them.
Wow 6 that must have been loud lol
Inside they seems rather quiet. But outside the exhaust for each on were all in a row. That low, bass, hum that you could hear everywhere.
Only saw one in my 26.5 year career. It worked, I gave it a meaningful stare and left.
Lol they are a bit different
I am a HVAC enthusiast but I must say, you know you stuff!
9:07 it almost sounds like a fridge compressor
Very similar to mine, been pretty terrible free
This is one of the worst furnaces ever made. Numerous major issues regarding safety and major recalls.
