Picture your field as a giant solar panel. In summer it will warm up and imagine the tonnage of soil which is at 12 degrees and just sitting there waiting to be transported into your house. If you have a machine (the heat pump) that can extract this heat from the water pipes buried in said field, presto you have a heat exchange. Magic eh! The best way to move heat is by water.........Hence damp clay. Dry sand just doesn't work so anyone with this type of soil should be looking at an air source.
By February you are struggling but if your pipes cover enough area you will still be able to extract some of this heat. This is a simple fact of physics.
What folk forget is this only extracts enough to heat to 55 degrees. No it's not rocket science just fact. Heat pumps are now so much more efficient they have an advantage over £'spent in this extraction process. Look at a modern freezer if you want to see how good this system is.
The big downfall is that the capital cost is big and I mean BIG but if you have faith and of course a field this is a good system.
Heavy clay is full of water.........it isn't frozen so it's above 0 degrees and possibly even + 5 in winter. You can extract this using your machinery. Your fridge does this every day of the year........
Me, I'm an insulation fan. 55 degrees is hot inside particularly when outside is at 0 degrees ie, freezing..........
