Hi,
Its prolly expansion/contraction of the pipes as they warm/cool.
Solution is to expose as much of the pipework as poss. Ensure it is adequatly clipped and not rubbing on anything.
You can lag the pipes too - old carpet pieces or proper lagging - it will deaden the sound.
Only other way is to change pipe for plastic.
