Heat Flow Density
HFD estimation errors
•Logging error caused by non equilibrium state
•Different methods of calculation
•Different depth interval taking for calculation
HFD mapping error
•Random scatter data for mapping
•Different approaches of HFD calculation in one image
HFD data
Different authors published data of HFD value
HFD evaluated on base of lab data of thermal conductivity
HFD value with using ofthermal conductivity model
Paleoclimate effect
The observed vertical variations of HFD in shallow part of profiles are mainly due to Holocene warming.
The lower part of profiles are still in thermal regime of the Weichselian glatciation.

• Unification of European HFD estimation method is required and shallow holes data should be recalculated
• Heat Flow in Poland includes in range 40 – 90 mW/m2
and according to the new results it is 40 – 110 mW/m2 that still concludes low enthalpy resources classification
• For last few year the growing interest in geothermic is observed in Poland, and local authorities requires a clear answer for its opportunities
