Gas absorption heat pumps Denmark Thermotechnology 1 General barriers with GHP on middle size consumers General statement seen from Robert Bosch Denmark  The GHP >30 kW have a further in the Danish marked, but in the near further only in Hybrid build up! – need of running houres pr. GHP  GHP is a unknown technology that is not common in Denmark  Natural gas marked is hard to penetrate with GHP due to very low gas prices  Oil marked can be converted to f-gas an give a fair payback time  Gas is by the politician seen as black energy and is planed to be phased out in 2035 for heating. This is said again and again, and make the consumer insecure!!  Robert Bosch Denmark believes that there is a marked for the bigger version of the GHP, but in the start the main marked will be in the “oil areal”

Thermotechnology Conclusion Bosch GHP is the best option because:  The repayment period is generally less than 5 years and is approx. 80% better than the next best solution  Viewed over the life of the product it pay back the investment approx. 3 times. Second best solution is approx. 2 times and the financial earning are significantly lower  CO2 emissions are less than half a second best option. Viewed over the lifetime of the product, the reduction of CO2 should be significantly less with Bosch GHP solution. 6 Gas absorption heat pumps Denmark

Gas absorption heat pumps Denmark Thermotechnology 9 Noise from Air/water GHP Barriers:  The GHP today is not design for “low noise”  It gives a lot of challenges to install GHP in close buildings areal. If the noise regulation is not met, it is the installers responsibility to rebuild the system so that it complies with regulations. All expenses associated with measuring is to be covered by the installer Solutions:  Development of noise reduction material for retrofitting
