Experts recommend flexible indoor heating temperatures

Energy experts are moving away from the long-standing 19-degree Celsius rule for indoor heating, which originated during the 1970s oil crisis. While 19 degrees was once the standard for minimizing energy consumption, modern improvements in home insulation and heating technology allow for more precise temperature control.

Experts suggest a flexible approach based on room usage rather than a single uniform temperature. A recommended baseline for living rooms and common areas is 20 degrees Celsius. Other suggested settings include 16 to 18 degrees for bedrooms, approximately 22 degrees for bathrooms when in use, and 17 degrees for hallways.

Energy specialist Brad Roberson notes that perceived warmth is influenced by factors beyond the thermostat, such as humidity, clothing, and physical activity. Maintaining appropriate temperatures is also important to prevent risks associated with moisture and mold buildup.
