Influence of the regulation framework on the feasibility of a Stirling engine-based residential micro-CHP installation

For that purpose, once defined the reference dwelling, with the consequent consumption patterns, an installation for covering heating and DHW (domestic hot water) demands of the building, as well as part of the electric load, is designed and simulated in TRNSYS 17, getting results of those performance parameters necessary for applying the economic analysis. A condensing boiler supported by solar thermal collectors is taken as the reference installation. Results show that pay-back conditions of this kind of installations have turned hardly achievable with new remunerative conditions, getting widely better results with economic frameworks of other European countries.
