humming noise in pipe

[william carr]

I am hearing a humming noise in pipes in my underfloor heating. It is possibly the circulation pump between the heat pump and the manifolds.Are there any dampers or silencers on the market ,which can be fitted to relieve the problem?

Check the pump's position. They don't have proper fixing points but you can get pipe clamps which can be used to fix the thoing to a masonry wall, say, which helps. Or you can use some plastic pipe (as in any heating system) in the line between pump and beyond, which transmits less noise. You can buy flexible connectors for use in heating systems but these are not the same as tap connector or shower pump flexies.
