Recently I have found the water for my hot water storage tank has been filling very
Slowly. However today I have found there is not water at all coming from any of my hot water taps in the house. I have also have not noticed any indication that water for the storage tank has filled at all. Water from the cold taps seem find and unaffected. There either seems a blockage in the pipes or a perhaps something preventing the water for the tank from filling up. What do you think? What remedy do you suggest?

When you open a hot tap do you hear a rush of air, if so allow the air to escape. If not shut off your main incoming water line and open the cold connection on top of the heater. You may find blockage and corrosian at this point, if not just come back here with what you see.
