Abstract

In this paper we describe the development and analysis of a hybrid heating system for space heating and domestic hot water that is designed to enable an energy-efficient supply of renovated residential buildings with an existing
radiator heating system, requiring high flow temperatures. The system consists of a dedicated air-to-water heat pump using the natural refrigerant R290 (Propane), a thermal energy storage, a photovoltaic system and an
advanced control. The development is done with the objective of a reduction of the system’s electrical energy consumption from the grid by 25 % compared to a defined reference system. Detailed system simulations in TRNSYS were performed to evaluate the effect of different measures concerning the heat pump cycle, the storage tank and the control for a renovated reference single family house. The results show that with a combination of all considered measures a reduction of the grid consumption by 32 % compared to the reference system is possible with a PV size of 10 kWp. With 5 kWp still a reduction of 25 % can be achieved.
