Figure 5From: Mapping the low enthalpy geothermal potential of shallow Quaternary aquifers in FinlandPotential aquifers for GWHP energy utilisation in Finland. Each dot represents a single aquifer. The dot colour indicates the categorised amount of heat (G). Numbers from 1 to 20 indicate the location of the 20 aquifers with the largest potential.
