Those work in hot dry countries. Lots of the UK - in particular the north-west - is neither hot nor dry.

Up here you end up with the outdoor part freezing into a block of ice.

I live in a similar climate and have never once had this problem in the winter. Something is wrong if this is happening to you.

Every one we've got fitted around sites at work freezes up in the rain. Given that they have to be outside, I'm not sure how to solve that.

Incorrect. Try a quality brand like Mitsubishi or Thermia.

These are all Mitsubishi ones, fitted by the manufacturer's recommended installer.

The problem is that the outdoor part has to be, well, outdoors, and that's where all the water is.

Canadians have air source heat pumps with backups that get used ~5-10 days a year...
