Usage Guidance

Water temperature depends on the incoming mains temperature and the flow rate. Adjust the flow at the taps to achieve the desired water temperature.

Performance Overview

The 13.5 kW model is powerful enough to fill a standard bathtub and is engineered to perform efficiently across various flow rates.
It activates at a minimum flow rate of 2 L/min and can accommodate higher rates effectively. The temperature increase depends on the flow rate:

• At 2 L/min, temperature rise up to 55°C (model-dependent)
• At 5 L/min, temperature rise 37–40°C
• At 6 L/min, temperature rise 31–33°C

For instance, filling a 150-litre bathtub at 5 L/min would take around 30 minutes. The heater can raise the water temperature by up to 40°C, ensuring a comfortable bathing experience.
