We have an old mercury switch thermostat in our house, You know the type, gold ring, very common.
We are in new England on a gas/steam system. There is no central AC.
We have been told by more than one heating professional that there really aren't any decent alternatives. The problem is that the thermostat doesn't report the right temperature, so it basically functions as a switch. The other problem is that my wife hates it.
I think we are on a 2 rather than three wire system. The house was built in the late 1920's.
Does anyone have experience with alternative thermostats?
