Optimal winter temperatures vary by room function, occupant needs, and energy goals. Here's a room-by-room breakdown balancing comfort, health, and efficiency.
| Room | Temperature Range | Rationale |
|---|---|---|
| Living Room | 20-22°C (68-72°F) | Primary daytime occupancy; sedentary activity |
| Bedroom | 15-18°C (59-64°F) | Cooler temperatures improve sleep quality; bedding provides warmth |
| Bathroom | 21-24°C (70-75°F) | Prevents chill after showering; reduces condensation/mold |
| Kitchen | 20-22°C (68-72°F) | Cooking generates heat; matches living areas |
| Nursery/Child's Room | 21-24°C (70-75°F) | Infants/young children regulate temperature poorly |
| Home Office | 20-22°C (68-72°F) | Sedentary work; matches living room comfort |
| Hallways/Entry | 16-18°C (61-64°F) | Transitional spaces; minimal occupancy |
| Unused Rooms | 14-16°C (57-61°F) | Frost prevention only; close doors, reduce heating |
Each 1°C reduction saves ~5-10% on heating costs. Strategic zoning (smart TRVs, zone valves) lets you heat only occupied rooms to target temperatures.
Comfort is subjective—use these as starting points, adjust for your household's needs, and prioritize vulnerable occupants' requirements.
