i have the same problem. i live in a mobile home and it is well below freezing outside, but the cold water will run and nothing comes out the hot water tap. it worked early today but no longer. i have a gas powered water heater and it gets extremely cold in my room (where the hot water heater is) so i put a space heater in there trying to fix the problem thinking maybe some pipe is frozen????? lol i am not a plumber. if anybody could help that would be great. thank you.
