The principle of the elastomer-metal-absorber (EMA) can be described as the tight connection of elastomer fluid tubes clipped in appropriately shaped metal profiles, acting as solar absorbers. This new kind of solar collector will be developed within an EU-project with partners from Austria, Germany, and Sweden. Several prototypes as well as test systems have to be built and evaluated. One important item, within the project, is to find suitable heat use concepts for the elastomer-metal-absorber. Therefore, the investigations in Sweden will be concentrated on combinations of this new collector with heat pumps and any kind of ground storage. Based on system simulations with the program TRNSYS, the most promising concepts will be designed and installed at SERC. The main objective of this thesis was to find the best solution for a combination of the EMA with a heat pump and bore hole storage. Therefore simulations were carried out with different heat pumps as well as with different designs of the bore hole. The optimisation of the ground storage became an especially important part of this work. Finally, the influence of characteristic parameters of the model that was used for the bore hole has been analysed. The investigations showed that the coefficient of performance of the whole system is much more influenced by different heat pumps than by different designs of the bore hole. The best heat pump led to an increase of the system performance of more than 10% compared with the base case system. However, improved U-pipe bore holes only increased the COP-values by slightly under 4%. Finally, it can be stated that there are still some uncertainties about the simulation model and that only a comparison with the test system that will be built will enable as assessment to be made between model and reality.
