Dave is owner and Director of Holymoor Consultancy Ltd. Dave has over 30 years professional hydrogeology experience from all sectors: consultancy, research, public and academia. It was also while working in Norway that Dave first became interested in ground source heating and cooling. It took several months to convince him that heat pumps really did work! On his return to the UK , Dave took up the challenge of persuading Britons that ground source heating and cooling could also be of relevance to their foggy & chilly island. The majority of Dave’s work with Carbon Zero involves some form of thermogeological consultancy, modelling, calculation – and training. Dave has particular experience of mine water based thermal systems.
