MODE OF OPERATION
Water-fed fan heaters are designed to provide heating in winter and ventilation in summer. They are ideal
for indoor areas such as shops, workshops and factories.
Heating:
The hot water produced by units such as the boiler or the heat pump in winter mode (not supplied), runs
through one of the water-air exchangers which is brushed by an air flow generated by an electric axial
helical fan running at three different speeds thanks to the accessory "variable speed switch with
SUMMER/WINTER mode" (accessory on request). As the air flows through the exchanger it absorbs the heat
contained in the coil and the air temperature increases.
Summer ventilation
During the summer the fan can be run on its own to provide ventilation.
