Hi,

When using a vertical borehole heat exchanger (with known resistance), how
the so-called "fluid-to-ground" resistance is defined? Practically, in the
particular case of a U-tube heat exchanger, is it an "effective" thermal
resistance (if there was only one tube) or the thermal resistance for a
single tube?
One more thing, the unit is not that clear ("any"). Is it [W/(m.K)]?

Thanks in advance,

Have a nice day,

Regards,
