        I’m having a problem with banging
        hydronic heating pipes. My second
        floor system which is piped thru
        the elements as usual and then the
        return loop runs thru the heater
        enclosure, then back to the boiler.
        I believe my problem is the velocity of the water rushing from
        the second floor and slamming into
        the closing zone valve. Would a water hammer device solve my problem?

          Removing one of the springs from inside the Honeywell zone valve sometimes helps. Replacing the zone valve with another model often stops the problem.
