Hello, I have had no hot water coming out of my tap since yesterday, is it my hot water system that's broken? The cold water is fine!

Is the issue just at one tap or does it happen at all taps and tubs? Gas or electric water heater? Have you tried draining water from the heater drain spigot, is that cold too?

Answer Bobs questions, Gas or electric? We must know that before we can continue. Regards, Tom

Polly, don't be afraid to post back during the daytime, Tom and I are here all day.

Hot water starts at the water heater. I would check on the heater first. Put your hand on LEFT pipe above the heater. See if it is hot. If not, answer the questions asked above and we will isolate the problem for you. Back to you. Milo
