Gerard Duffy, mechanical engineer specializes in renewable energy solutions from 1984, projects including family homes, office blocks, hotels, churches, and public buildings. Mr Duffy introduced heat pumps to Irish customers in 1987 to heat existing radiators and new underfloor heating system. The new Eurotech Eco4 Light, overfloorheating system opens the door to retrofit heatpumps successfully in any existing building. Passionate about spreading the good news about geothermal heating. Gerard played an important role in the Geo Fit project at Galway University, using 18 No. geothermal boreholes to provide the energy for two heat pumps designed to heat the Olympic swimming pool. Gerard says, the most efficient heating system is the one that uses no energy, heat pumps offers a path to reduce energy while Solar power decarbonizes this solution.
