I had a Keston C36 fairly hefty combi boiler installed last November.
The central heating part is still nice and quiet, but Direct Hot Water has got progresively noisier over the last month or so and has now got to the stage where it sounds like concorde taking off.
Also, once I've turned the tap off, the temperature display on the front of the boiler often seems well over the DHW temp setting, like 71 degrees.
It then takes up to 4-5 minutes for the boiler to "wind down" and turn off.
It's got to the stage where I'm scared to turn a hot tap on, except for something major like a shower or a bath!
Any clues as to what the problem could be?
