The documentation indicates that the thermostat on the tank has a range up to 210F. I can't test the water temperature when it's in the tank. I can only test it when it comes out of the tap. They are coming out to switch out the tank because I can only measure 185 F but they've admitted that I will never get 210F to come out of the tap. The marketing department needs to be schlept upside the head for the publication. The customer wants to know what water temperature they will receive.
