A thermostat is a temperature sensitive "door". If your car did not have one, the coolant would be circulating all the time and the engine would take a long time to warm up to optimum operation temperature. The Thermostat stays closed until the engine gets warm and then opens when it starts getting hot to allow the coolant to flow through the radiator and cool down.

To test a hot water heater thermostat, you can use a multimeter to check for continuity in the thermostat. First, turn off the power to the water heater. Then, remove the access panel to expose the thermostat. Use the multimeter to test the thermostat's terminals for continuity. If there is no continuity, the thermostat may be faulty and needs to be replaced.
Drain the radiator into a suitable container. Remove the top radiator hose at the engine. That is the thermostat housing. Remove the 2 bolts and remove the thermostat. Clean the thermostat housing and the intake manifold and install the thermostat. It is not necessary to use silicone sealer but if you feel you must then use sparingly.

When setting up a Nest thermostat, use the RH wire if you have a heating system, and use the RC wire if you have a cooling system.
You should use a thermostat gasket along with the thermostat housing ring. The gasket should be replaced every time the thermostat housing is opened.
