This analysis considers a commercially available domestic gas boiler as a heat source for a domestic organic Rankine cycle system. An experimental study was made into the applicability of the gas boiler (De Dietrich with thermal power 25 kW) coupled with the laboratory prototype micro ORC setup. The main aim of the study is to determine the working fluid temperature, attainable heat rates and efficiencies of the whole system. Preliminary investigations show that the boiler was able to provide saturated/superheated vapor of ethanol and HFE-7100 as a working fluid at the required conditions needed in the ORC system and it can be utilized as a heat source in a domestic micro-CHP. The results should encourage future development of micro cogeneration units.
