3 TECHNICAL DATA HW WATER HEATERS
Functional introduction
The HW water heaters are 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
(110
ppm average) and an annual average of 30 mg/m 3 . (22 ppm average)
