Ducting a Heat Pump Water Heater for Sound Control
I have an A.O. Smith heat pump water heater and it is loud enough that I can hear it in the kitchen from the basement. It’s not super loud, it reminds me of the way refrigerators used to sound when I was a kid, it’s more that the tone it makes is irritating. So I’m looking at ways to quiet it.
I know that sometimes in HVAC work flexible insulated duct is used for sound isolation. I’m thinking that maybe putting 8′ or so on the intake and outlet might help.
