Problem: The water in the Cold Water Tank is getting hot!
I have tried lengthening the overflow pipe from the top of the cylinder, as I suspected that it was too short and resulting in hot water expanding into the cold water tank – made no difference.
So while looking inside the coldwater tank I noticed heat radiating from the hole which feeds the hot water cylinder tank, which would cause the water in the coldwater tank to get hot. I checked the coldwater feed to the hot water cylinder and it is very hot!! Is this normal? If not, what is the likely cause for this? Is there not a valve to prevent backflow? Is the tank getting too hot and radiating back up the coldwater feed?
The thermostat appears to be working fine and switches the valve off when it reaches 65 degrees?
Please help!!
