This thesis presents a simulation-based analysis of three heating systems in a reference apartment: radiator heating, hydronic floor heating, and electric floor heating. The aim of the study is to evaluate the differences between these systems in terms of energy consumption, thermal comfort, and system responsiveness under identical operating conditions.
A multi-zone thermal model of the apartment was developed in the MATLAB/Simulink environment. The model is based on the energy balance of individual zones and considers heat losses through the building envelope, air infiltration, internal heat gains, and solar radiation through windows. The heating systems were implemented using a common on/off control strategy with hysteresis, which enables a direct comparison of their operation. Simulations were carried out using Typical Meteorological Year (TMY) weather data.
The analysis focuses on electricity consumption, total heat delivered to the rooms, peak heating power, and the stability of indoor temperatures. For the heat pump systems, the coefficient of performance (COP) and seasonal performance factor (SPF) were also evaluated.
