We recently fitted a new vaillant 418 and range tribune 180l unvented cylinder at a friends house with powerflush, magnaclean etc etc but he is having problems with his hot water.
Old cylinder position was the airing cupboard on the landing new position next to the new boiler in the garage. Problem he is getting is on all of his hot taps the water is going cold then hot even though there is a full tank of hot water. It happens whether heated by the immersion or the boiler. Anyone had any similar experience? Can't ring kingspan/range until Tuesday now!
