      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.
