Abstract: Among the renewable sources systems for space heating, air-source heat pumps are the most promising technology. The air-source heat pumps European market is dominated by air-to-water and air-to-air heat pumps. In this study we present a comparative analysis of these two types of machines, in terms of electricity consumption. Buildings (with low and high thermal inertia) and their heating systems were simulated in different European climates. Results show that the thermal inertia of the envelope penalizes the performance of the system and this effect is more pronounced in the AW system.
