Home heating and thermal comfort standards
Overview
Experts and specialists are re-evaluating domestic heating standards and thermostat management to improve thermal comfort and energy efficiency.
Recent discussions highlight the limitations of the traditional 19°C heating standard, which was originally rooted in 1970s energy austerity decrees. Experts note that 19°C may not provide adequate warmth due to factors like humidity, air movement, and radiant heat loss from poorly insulated walls. Such walls can act as heat sinks, making a room feel as cold as 16°C or 17°C. There are also concerns regarding the physiological well-being of aging populations who may find the standard temperature insufficient, as prolonged inactivity can reduce internal heat production.
To address these issues, specialists suggest moving toward a flexible approach based on room usage rather than a single uniform temperature. A recommended baseline for living rooms and common areas is 20°C to ensure comfort and reduce mold risks. Other suggested settings include 16–18°C for bedrooms, approximately 22°C for bathrooms when in use, and 17°C for hallways.
Energy specialist Brad Roberson notes that perceived warmth is influenced by factors beyond the thermostat, such as humidity, clothing, and physical activity. Additionally, users are advised that thermostat numbers often represent target room temperatures rather than power levels, and that avoiding overheating—such as by lowering temperatures by just 1°C—can save approximately 5% in heating costs. Simple adjustments, such as moving furniture away from cold walls or using reflective panels, may also improve comfort without increasing energy consumption.
