1 Three important E:s in Heat Pump Technology Energy Environment Economy Swedish Heat Pump Association European Heat Pump Association

2 Typical Ground source heat pump (5.5 kw th )

3 General working principal Radiators Under floor heating Compressor Heat sink Fan-coils Ground rock Ground Source Heat source Ground soil Coefficient of performance (COP) = Ambient air

4 Ground source heat pumps Horisontal ground soil system Vertical ground soil/rock system Evaporator Condenser Heating system Domestic hot water

5 Ground source heat pumps Horisontal ground soil system Vertical ground soil/rock system Tight lid Steal lining Layer of ground soil Bedrock minimum 2 meters lining pipe Welded joint Seal between lining pipe and bedrock

6 One family house Ternitz (Austria) 240m² living space 11 kw Geothermal heat pump 280 m² Flat collector Controlled ventilation

7 One family house Ternitz (Austria) Seasonal performance factor 5,3 Energy costs EUR 390,- Energy savings Oil 1923 Liters CO 2 4,1 Tonnes

8 Multi-family house, Norrtälje, Sweden Number of flats: 90 Heated area: m² Previous heating system: Oil boilers New system 4 x GSHP 40 kw + oil boiler (back-up) Heat source: 19 boreholes x 173m Annual savings: euro Pay back time: 4 years

10 Commercial building, Les Mureaux, Paris, France Office building Conditioned area: m² 1 Ground water heat pump (290 kw th ) Utilasation heating + free cooling

11 Commercial building, Les Mureaux, Paris, France Under floor heating and cooling system Seasonal performance factor heating: 4.1 Seasonal performance factor cooling: 8.2

12 Demands on heating systems Consumer perspective Functionality Heating Cooling Reliability Operational reliability lock-in effects (depency on one supplier) Convinience Operation and maintenance Space requirements Simplicity in installation Economy Investment costs Operating costs Environmental impact Green house gas emissions Particles Acidification Eutrophication

13 National perspective Energy efficiency Primary energy efficiency Environmental impact Green house gas emissions Particles Acidification Eutrophication Renewable energy sources 20% by 2020 The proposal for a renewable energy directive was published yesterday!

14 System boundaries Primary energy Purchased energy End use energy Extraction Refinement Transportation Powergeneration

15 Reduction of green house gas emissions 100% 90% 80% 70% Nearly 60% reduction 60% 50% 40% 30% 20% 10% 0% Oil boiler Heat pump Reduction of CO 2equvivalents when heat pumps are replacing oil boilers Efficiency oil boiler 90% Seasonal performance factor heat pump 4 Electricity based on EU-25 mix

16 Reduction of green house gas emissions 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Gas boiler Heat pump Nearly 40% reduction Reduction of CO 2equvivalents when heat pumps are replacing gas boilers Efficiency gas boiler 95% Seasonal performance factor heat pump 4 Electricity based on EU-25 mix

17 Primary energy savings 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Oil boiler Heat Pump Primary energy savings when heat pumps are replacing oil boilers Efficiency oil boiler 90% Seasonal performance factor heat pump 4 Electricity based on EU-25 mix

19 The Swedish success story More than heat pumps installed since Air-air Vätska-vatten Exhaust air Frånluft Luft-luft Geothermal Luft-Vatten Air-water

20 Ground source heat pumps in Sweden

21 Ground source heat pumps in Europe % 7% 1% 4% Austria 13% Estonia Finland France Germany 40% Norway 2% 26% Sweden Switzerland

22 Enormous potential Our vision! 1 million ground source heat pumps/year by 2015
