The house was built about 50 years ago and the 2nd story addition was put on 20 years ago.
We use oil and the heat is produced by forced hot water system.
Until a year ago we had the two systems working but they were getting very old.
Since we installed a new high efficiency heating system the pipes on the 2nd floor make major clicking and hammering noises!
The plumbers who have come and listened to the sound suspect the pipes on the second floor are expanding and hitting the floor boards. They suggest we have the floor removed (carpet) so they can fix the pipes. This is a major undertaking and we can't quite pinpoint all those areas where the noise comes from!
Is there a different solution?
