I finished my storage / boiler room off last year so my daughter could have a art room. I have installed my geo. systems in the same room, she was happy to hear she would not have to listen to the oil boiler anymore but is now saying the water in the pipes is noisier then the boiler. I think she is right so I built a enclosure that mounts around my flow control valves and flow meters, it helped but the 3/4 copper pipes are still amazingly noisy going in and out of the enclosure. So does any one know of something I can wrap around the pipes to quiet them down? Pipe insulation does very little to help with the noise??
