    As a Briton not used to these things at all, I would think surrounding it in sandbags is the more aesthetically pleasing option.

      As a Briton, I can't help thinking that once the unit is in place, with its double-wall sandbag enclosure (including 4' service space), I won't have any garden left.

        Why bother building the other three walls? Wouldn’t one SB wall between the unit and the exterior wall of the building cut down the noise enough?

          Well... supposing I did have a bit of garden left, I might like to enjoy it in peace without hearing a constant noise of machinery.

  It needs good air flow to work well and the noise is only really a problem inside the house in the room next to it. I may put some sound insulation on the wall at some point.

  Really? I'm curious what brand of heat pumps these are. I have two air source units. One is a whole home Carrier Infinity unit (4 ton) and a GE single head ductless mini-split. The Carrier heats and cools our entire home save for a sunroom that's not ducted which is why we also have the mini-split. I never hear either unit.
