I've been searching this forum but couldn't seem to find the answer to my problem hence posting this thread.
I refurbished my house recently and the hot water tank which was downstairs was moved in the loft by a plumber. It sits just underneath the cold water tank. The hot water is set on timer so boiler heats up the water only once in a day. Knocking/banging sound is coming up every time boiler starts heating up the water. It goes on for about 5 to 10 minutes and then everything goes to norm. This is happening only when the hot water is coming on and not with the central heating.
I hope you guys would be able to suggest something and I'm sorry if I've posted a question which have been answered in the past.
