Topic of the practice

The practice describes the market success in Sweden for GSHP (Ground Source Heat Pump) for private and public housing.

Good Practice Information

The market success for GSHPs in Sweden for private and public housing is a result of a technology procurement in 1994-1995 by the Swedish National Board for Technical Development (NUTEK) on heat pumps. This got quite a lot of attention and the sales started to increase rapidly. There were two winners in this procurement and both were ground-source units. The technology procurement has led to faster adjustment towards a fossil free society. Key figures:
300 000 installed ground source systems:
- Borehole heat exchanger 70 %
- Shallow Ground heat exchanger 25 %
- Ground water heat pump 5 %
- 10-12% of the residential heating in Sweden
- Reduces the usage of fossil fuel(oil) by 1,2-1,5 million m³/year
- Reduces CO2 emission with 2,5-3,0 million ton/year

The Swedish National Board for Technical Development (NUTEK) was involved in the market opening procurement for single family houses. In later procurements has public as well as private housing companies and housing associations been involved, both making requirements and promising to buy a number of the winning systems. Ground source heat pumps are an ideal combination for a country with a cold climate and hydronic heating systems. The heat pumps are also possible to retrofit in houses without a boiler room. Technology procurement can be used as a market opener for new technology on all markets.

Evidence of success

As a consequence of the procurement, GSHP began to dominate the market The total sales in 2002 had increased more than 400 % from the technology procurement 7 years earlier. Since then has the annual sales stayed between 20 000 - 40 000 units. Reduces the usage of fossil fuel(oil) by 1,2-1,5 million m³/year. Reduces CO2 emission with 2,5-3,0 million ton/year
