Hot Water Heat Issue

I recently added an addition to my house and added an additional hot water heat zone. This zone consists of the extra space added during the remodel and previous room space from another zone. I know have a situation where the newly added copper lines make a knocking noise when heating up. How can I address this knocking sound?

Looking forawrd to a good nights sleep.

Thanks.

Knocking is usually from the tubing expanding and rubbing the studs or mounting brackets. If you have long straight runs it is more likely to occur. The best was to eliminate it is to have expansion loops in long runs. If the tubing is coming up through a floor and then going back down, it will help to enlarge the holes the tub passes through to give it more room to move.
