TECHNICAL DATA WATER HEATERS
Functional introduction
The HWB water heaters are central heating water heaters with a maximum high efficiency. Such a performance
can be reached by, amongst other things, using a special heat exchanger made of stainless steel. This allows the
flue gases to cool down below the condensation point, and so release extra heat. This has an immediate positive
impact on the efficiency.
The water heater is set for Natural gas.
Fuel used should have Sulphur rates with a maximum annual peak over a short period of time of 150 mg/m
3
