The general guideline for turning on the heat in a house is when indoor temperatures start to feel chilly or fall below approximately 64°F (about 18°C). Many experts recommend switching on the heating when the outdoor temperature consistently drops below 15°C (about 59°F), which usually happens around mid-October in many regions. Some also suggest starting to use heating when indoor temperatures fall below 64°F to 68°F. The exact timing depends on personal comfort, the insulation and condition of the home, the needs of the household (especially for older people or those with medical conditions), and weather patterns. A common practical approach is to turn heating on about half an hour before getting up in the morning and turn off when leaving the house or going to bed, adjusting based on comfort needs. In summary:
- Turn heating on when indoor temperature feels cold or drops below around 64°F (18°C).
- Outdoor temperatures consistently below 15°C often signal heating season start.
- Mid-October is a typical time to turn on the heat in many places.
- Adjust according to your home's insulation and occupant needs.
This approach balances comfort and energy efficiency.
