The ideal temperature for a house generally falls between 18°C and 21°C (64°F to 70°F) for most people to feel comfortable and maintain health. This range is recommended for living areas during colder months. Different rooms may have slightly different ideal temperatures: living rooms and home offices are best kept around 19-22°C, kitchens slightly cooler at 18-20°C, bathrooms warmer at 20-24°C, and bedrooms cooler at 16-19°C for better sleep. For infants and elderly people, temperatures at the higher end of the bedroom range are advised for safety and comfort. Temperatures should never drop below 14-16°C to avoid health risks and issues like damp or frozen pipes. During warmer months, house temperatures are ideally kept between 23-25°C for comfort without overheating. Adjusting the thermostat down by one degree can also save significant energy and costs without sacrificing comfort.
