My cold water storage tank feeds the hot water cylinder and also a shower with a pump. On several occassions the shower has been too hot to use. My initial reaction was that the shower was faulty but decided to do a bit of diy investigating and discovered that the cold water storage tank contained hot water. It appears that heat is tracking back up the feed pipe from the hot water cylinders as this pipe is very hot.
Is this possible? If so what can be done?
