water hammer with central heating

Hi, When my thermostat reaches temp Is it common to hear water hammer? Should this be silenced or buffered in any way? The noise seems to come from above my celling. (where the valve must be) and can be clearly heard shutting 3-4 times a night. Could this also cause damage? Is it common to hear wate...

He said that it basically was supposed to do this? (make a bang noise and it was the design) Is this common? If...

thankyou!! One more small question (i promise) I moved into a new build, so I guess they put the external bypass there if I wanted to change the boiler (without an internal bypass).

A plumber eventually diagnosed the problem as being the external bypass in my heating system being fully open causing alot of the hot water to go directly back to the boiler. He closed the bypass fully and now the heating is 10x better...
