Ground source heating and cooling in Sweden

Dec. 22, 2009 – Ground source heat pumps (GSHP) were appearing in Sweden by as early as the end of the 1970s as a contribution to reducing the country’s dependency on oil. Horizontal and vertical closed-loop systems, together with a small number of systems extracting heat from ground water (open-loop systems) are currently replacing some 1.5 million m³ of oil annually.

In recent years, there has been a steady growth in larger systems for combined heating and cooling, using the ground for seasonal storage of heat (UTES). These systems show a steady growth, due to their high potential for energy savings.
