Using the home checklist Heating and cooling Easy Actions Do you heat or cool just the rooms you are using? No
Heat or cool the areas being used rather than paying to heat/cool empty rooms Close doors to stop warm/cool air from escaping to rooms that aren’t being used Block draughts between heated or cooled rooms and rooms that aren’t being used
In winter, is the heating set too high, i.e. too warm? Yes
Set heating at 19° to 21°C (use a thermometer if you don’t have a thermostat).
In summer, is the cooling set too low, i.e. too cool? Yes
Set cooling at 24° to 27°C (use a thermometer if you don’t have a thermostat).
