1.3.1 Lower the DHW temperature set-point

1.1.3 Lower the DHW temperature set-point Description Water should not be overheated more than necessary (each 10°C rise in DHW temperature increases the energy consumption by around 15%). To save energy, it is recommended to adjust the thermostat of DHW at 60°C (this temperature should not be reduced to avoid problems of [...]
