    The only knowledge I have of ground source heat pumps in Scotland is in relation to some new build houses a few miles from our home - it's on the route of one of our dog walks.

    They were built two years ago and all have ground heat source pumps. They're truly stunning houses - lovely architecture for new houses and good build quality. This is why I paid so much attention to them. Anyway, after the first winter almost every one of them had a shiny new woodburner chimney! So I'm assuming the ground heat source pumps aren't up to the job. It's not even that cold where we are - we're close to the coast so it never gets too hot or too cold here. 
    Can't speak for your dog walking route but, in general, GSHP's achieve a higher SCOP than ASHPs provided the coils are installed correctly in a sufficient land that receives solar irradiance.
