Should be a guage either where the hot water cylinder is maybe attached to a red vessel normally 1-4 bar

Its sitting at two bar, we have a red vessel with a gauge and there is also a white pressure expansion vessel on top of the tank with no gauge.

Red one is heating white is your hot water so looks like it’s time to call nibe out it’s either a sensor fault or fridge side

Many thanks, the system we have is a fighter 2015 hooked up to a water tank specially made by Copper Hot Water Cylinders - vented, unvented, thermal store - https://mcdonaldwaterstorage.com/, Nibe will only service the tank.. Apart from the white expansion tank failing we have had no problems with it for 11 years. Shal give them a ring.
