Just installed heat pump systems (daikin) this december.
The exterior unit is basically silent even when there was a cold snap (below freezing but not northern alaska cold).
I suspect an interior air source heat pump hot water heater, being smaller, will be noisier, and likely less efficient.
I'd love to switch my 240v/30a water heater to use a 120v/20a service, but will wait a bit longer for the technology to mature. Ideally it'd have the heat collection part outside.
