Sounds to me that there is some wires crossed.... I mean some waterlines crossed.
If there is no hot water when hooked up to city water, I'd say they have hooked the city water to the hot water line that comes out of the
HW tank, instead of hooking it up to the cold water line that feeds the HW tank. In this case the HW tank is being bypassed.
If that is the case, it is possible that the Hot water line feeding the kitchen sink is hooked up to the cold waterline that the city water should have been hooked up to. Probably just need to change the two lines.
On Edit ~ In our 2980 Near the HW tank 3 waterlines feed down through the floor in the basement. Hot & cold to the Kitchen sink & one line to the city water connection. the more I think about it, I could see someone reversing a couple of these lines.
Just a theory
