ASHP in cold well
Great experiments!
I know it is a more extreme option but you could raise the heat pump. Either wall mount or more easily build a 1m ish high foundation for it. Maybe store something under it to make space useful.
@adam-c Hi - yes, I think that could have been considered at the design stage, though I wonder if we'd have heard the fan running if it was attached to the wall ? Now it's there I'm not going to ask the installers to move it.

@derek-m No smoke today but I've been monitoring the temperatures at the outdoor unit and comparing to well away from it as you suggested, they are generally the same 👍 So that's a great result. However, the shed is really in the way where it is now, so I'm going to dismantle it and replace it with a much smaller storage unit which I hope will do the same job of blocking the cold air.
We haven't had much in the way of calm weather, when the cold well would show up more. When I've got the new store in position and it's a calm day I'll light up another smoke pellet!!
@heat-pump-newbie we never got a conclusion to your trials and experiments. Whatever happened and what conclusions did you end up coming to?

Hi Mars
I did remove that little shed altogether. There are two gates enclosing the triangular shaped yard and I always leave the inner gate open to let the cold air escape. The other gate is usually kept bolted so to improve the air flow entering the yard I might move the slats on it, or get a new double slatted gate.
I might well get the unit raised up as suggested. I have another problem: the concrete surface of the yard is breaking up, there is a retrofitted drip tray under the unit with a too-small drainage pipe which has no fall to the nearest drain, so blocks with ice in sub zero temps. It won't last more than a couple of winters before it's just a mess out there. I think raising it up would mean a proper drain pipe could be installed, with a decent fall (soakaways don't work on our clay), with the added advantage of letting the cold air dispurse.
However, watching the HeatGeek video about air recirculation it seems it's not such a problem as I first thought.
