High leaving water temperature

The temperature of leaving water can go up to 55°C without a backup heater. Hot water can be continually supplied throughout the house, even when the outdoor temperature drops to -10°C.

If you want to raise the temperature of the water supply to above 55°C, use a backup heater to supplement the primary heater.
