How it works
- 1Heat balance (same medium): T = (hot×Thot + cold×Tcold) ÷ total
- 2T = (90 × 60 + 60 × 15) ÷ (150) = 42 °C
- 3Hot share = 90 ÷ 150 = 60%
Comfortable bathing range is 38-42°C; 37-38°C for babies, under 40°C for the elderly. Set the water heater at 50-60°C - hotter wastes energy and risks scalding. Run cold water first, then add hot. A thermostatic mixing valve auto-regulates, but big pressure differences cause temperature jumps. In winter tap water is colder (~10°C), so increase the hot share.
