co2 ashp..
So what are the advantages of CO2?
Is it just that it is ozone friendly?
I had heard that there are co2 systems in Japan and I guess this is the first of them to go outside of that market.
But the prices are very high..my two 100m boreholes were only 8000 us dollars. Granted if you haven't got the space for the groundworks then air source is the way ahead.
Any other thoughts?
