Abstract
Within the frames of this project there are ongoing measurements of five different heat pump facilities used for heating houses and tap water in one-family houses. The measurements started in the first part of 2010 and are supposed to go on for one year. The final result together with analysis and discussions will be presented in a report that will be published in summer 2011. The purpose of the measurements is to present the potential for heat pump technology in order to raise the acceptance of the technology and through raised acceptance increase the implementation of the technology in new markets. The project also has its purpose in usage of the results and conclusions as basic data and guidelines for constructors and assembling fitters. The project is not intended to grade individual heat pumps from various suppliers in regard to efficiency. A field study does not adapt well for comparison between different heat pumps since there are too many variables (outdoor climate, usage pattern, construction of the building, installation solution, kind of heat pump system) that affect the performance of the heating system. Results from field studies should therefore never be used for comparison. This kind of work should be

Results from field studies should therefore never be used for comparison. This kind of work should be carried out in a laboratory where variables that affect the result can be controlled. The project started with a mapping of the Swedish heat pump market in order to obtain a base when choosing the different heat pump facilities that should be included in the field study. The selection was made together with the heat pump manufacturers with focus on selecting the best possible technology and to include different technologies. Another important criterion for the selection was to find households that agreed to participate in the study. Included in the study are two buildings with geothermal heating, one with geothermal heating combined with solar panels, one brine/water heat pump connected to a ground storage combined with solar panels and one building with an air/water heat pump combined with solar panels. Collaterally with selecting suitable households a selection of the equipment used in the field measurement was carried out. The equipment for the field measurements was chosen with the purpose of obtaining a high accuracy on the measurements and to be able to collect the data by remote sensing. To have equipment that restarts after a power shortage was also a requirement. The data collected in the project are temperature (Pt-100 sensors) and volume flow (by induction with pulse output) on heat carriers and tap water as well as electrical energy (electrical energy meter with pulse output) which the heat pumps and circulation pumps uses. The indoor and outdoor temperature is also measured. All the measured values are collected by remote sensing. Since the duration of the measurements is very limited only some preliminary conclusions can be drawn. The limited duration of the measurements also implies that the Seasonal Performance Factor (SPF) for the various facilities cannot be accounted for in this report. The (Coefficient Of Performance) COP is presented per week instead. The results from the measurement performed so far are used in order to determine the heating systems Coefficient Of Performance (COP), electrical energy saving and carbon dioxide reduction in comparison with direct acting electricity. A yearly Seasonal Performance Factor (SPF) and a degree of energy coverage will be determined for one year when the measurements have lasted for one year and will be covered in the final report}
