This study analyzed the integrated facilities based on an electric driven air to water heat pump(e-AWHP) suitable for a domestic residential buildings, and evaluated the water heating energy efficiency using(e-AWHP). Analysis of integrated facilities applied to Western Europe basically includes (e-AWHP), ventilation, and domestic hot water(DHW) tank. In addition, PCS is applied additionally when PV is applied. Since most residential buildings in Korea have floor heating, it is possible to increase energy efficiency by applying radiant heating and cooling using (e-AWHP). It is appropriate to organize all elements of the integrated facility into single package, as small buildings in Korea have a narrow area of land and prefer to separate the machine room from the residential space. For the hot water performance test, 8.38kW (e-AWHP) and 200L DHW were composed of a single hot water supply system, and the performance evaluation according to EN standard confirmed that the water heating energy efficiency was 61.63%.
