Dunstar Ltd - The Solterra™ people


Dunstar Ltd. are the pioneers of the geothermal heating industry in Ireland. Established in 1990, we offer a non fossil-fuel based central heating system, which offers the lowest running costs available in Ireland today.

We are the manufacturers of the Solterra™ range of geothermal heat pumps - with a heat output range from 6kW through to 36kW. We have the largest installed capacity, with over 500 up-and-running domestic systems in 32 counties.

We are approved installers for ClearSkies grant assistance and our products have passed D-A-CH certification to ensure we continually progress in line with international standards.

Based in West Cork, we are currently the only company who control geothermal installation from manufacture through to commissioning - which means that our customers can rely on efficiency, reliability and thorough technical support from start to finish.

In the commercial sector, Dunstar have a unique portfolio of commercial applications.

Our unequalled expertise and contribution to Irish technology and energy conservation is repeatedly awarded. Most recently, at the ESB SEI Energy Awards, we picked up both the Commercial and Overall Thermal Energy Awards for our efforts in Glenstal Abbey and the Lewis Glucksman Gallery, UCC.
