Rethinking Home Heating: Flexible Temps Deliver Comfort and Lower Bills

After decades of following a fixed 19°C guideline, health and energy researchers now favor a flexible temperature range (roughly 18–21°C, room-dependent) guided by WHO and the UK Energy Saving Trust. Steady temperatures with smart controls and TRVs can reduce condensation and mold risk, while avoiding energy spikes from frequent reheating. Ventilation, humidity control (below 60%), insulation, and draught-proofing complete the picture, making comfort and savings compatible.
