House Heating System
This example shows how to model a simple house heating system. The model contains a heater, thermostat, and a house structure with four parts: inside air, house walls, windows, and roof.
The house exchanges heat with the environment through its walls, windows, and roof. Each path is simulated as a combination of a thermal convection, thermal conduction, and the thermal mass. The heater starts pumping hot air if room temperature falls below 18 degrees C and is turned off if the temperature exceeds 23 degrees C. The simulation calculates the heating cost and indoor temperatures.
The manual switch allows you to investigate system behavior with the heating system turned off.
