Opening the curtains can help to heat the room TARA MOORE■ When it’s cold, use extractor fans sparingly: they draw out the warm air. ■ Keep curtains open during the day, as the sun will heat the room. In winter, close them at night, before the temperature drops, so the heat doesn’t escape through any gaps in windows. ■ Don’t place sofas in front of radiators, as they will absorb the heat rather than let it circulate. ■ While some ventilation is necessary, and there’s nothing wrong with a few natural draughts, use excluders around the edges of external doors and the letterbox.
