What is night or un-occupied setback temperature and do I need it?
During the day you would typically set your room temperature controller to 20C. During the night or when the building is un-occupied you do not need to heat the house to the same daytime temperatures. If you turned the heating off completely the house would go very could overnight and the heating system would take a few hours to warm up again in the morning. How long would be decided by how cold the air temperature was overnight. So to overcome this problem and at the same time reduce the energy consumption during the night we use programmable room thermostats that allow you to select a lower, typically 3C – 4C, setback temperature during the night. If the house temperature drops to the level set by the user the heating will automatically come on until the setback temperature is reached. For added comfort and efficiency Underfloor Heating1 recommends that all heating systems control packages should unclude night or un-occupied setback temperature control as standard.
