When leaving home for 8-10 hours, setting the gas boiler to 17°C can save energy compared to maintaining 21°C. If absent for 8 hours, keeping the temperature at 21°C during the day may yield similar energy consumption as maintaining 21°C all day. The most significant savings occur when reducing the temperature by 4-5.5°C during absences, potentially leading to a 10% annual reduction in heating costs. Energy experts recommend a comfortable range of 18-21°C and suggest lowering the thermostat when the house is empty to avoid unnecessary energy use.
