i have a calorifier fed by cold storage tanks above this months temp check showed a temp well above 20c the favourate theory is that a fault in one or more tmvs is causing ingress of hot water 2 tmvs are showing incoming cold pipe temp exceeds 20c if hot tap is turned on would this really be enough to raise temp in cold tank by several degrees:tounge_smile::disappointed:

Absolutely.

tmvs sorted and all other avenues explored it has been suggested that a broken or disintergrated dip tube would cause this problem any suggestions would be much appreciated
