I have one of those old-school thermostats at home, the kind with little dials to adjust the temperature, from about 15 years ago. The heating works fine but I was wondering if it's worth replacing it with a newer one or if these old ones are just as reliable. Does anyone have experience with these devices?
Is it working well for you right now and does your heating bill seem normal? If so, honestly it's not worth replacing. A mechanical thermostat like that is practically indestructible - it doesn't have complicated electronics that can break down and it keeps regulating the temperature reliably. The only reason to change it would be if you want to control your heating from your phone or save energy with more precise automatic programming, but if it's working and you don't mind adjusting it manually, it could easily last another 15 years without any issues.
