Thank you Daox ,

I was thinking about placing a spiral of 'mains water filled black piping' down the bore hole (ie 25 meters deep). this would be a lot of tube but I was wondering if that would guarantee the coolest circulating water and remove any problem of rust and eliminate any risk of fouling another aquifer.

I would then need to consider the cheapest (ie as in cost of running) pump to cause this water to circulate.

I have also considered insulating the above ground pipe to prevent heating of the circulating water .

The next step might be to use a number of old computer fans to push air through a coil of black pipe into my selected rooms beside my existing ducted heating.

What do you think?

regards
David
