A Whispergen Mk Vb 1KWe Stirling Engine mCHP unit was integrated into a test rig simulating a typical UK domestic hydronic heating system and tested implementing derived heat demand profiles in the house over the yearly period. The obtained experimental performance was used as input data for static simulations in CANMET Energy RETScreen software to calculate economical and environmental benefits from deployment of the mCHP instead of a condensing boiler. Simulation results show that a 16% annual monetary savings can be achieved due to the introduction of new UK feed–in tariffs. The payback period when using the mCHP system instead of a condensing boiler is about 8 years. These results can be used for determination of strategy for further improvement of the performance of the unit.
