The existing heat flow pattern of Central Europe is reasonably well known since the late eighties. However, in recent years additional geothermal data have been accumulated which provided a certain possibility to reconsider the previous knowledge and update it. A revised version of heat flow map of the Czech Republic is presented together with the maps of the isotherms at depths of 500, 2000 and 5000 meters. The geothermal data were thoroughly completed with similar information available from the surrounding countries, the paleoclimatic corrections were applied on the whole dataset. 3D numerical model based on the additional information summarizing the results of the laboratory measurements of the radiogenic heat production and heat conductivity of collected rock samples was proposed to describe the crustal thermal structure of the studied territory and allowed to delineate the potential zones for the utilization of deep geothermal energy. The influence of the convective heat transfer on subsurface temperature field in the discharge and recharge areas, namely in southern and western Bohemia, was briefly discussed in context of regional heat flow density pattern.
