District heating tank FSN and FSN-E
1. Description
B F
The district heating tanks are storage tanks that are heated via the district heating grid. The flow tem-
peratures required for this should be at least 60 °C. For district heating grids that do not operate all year
round there is the option of electric heating with the FSN-E type series.
The device is distinguished by the following characteristics:
• Double enamelled steel plate internal boiler with protective anode.
• High quality heat insulation made of polyurethane foam (CFC-free); boiler foam-fitted directly into the
outer casing. Benefit: low standby energy consumption.
• Stove enamelled, powder coated outer casing of steel plate, white.
• Precisely displaying capillary tube thermometer.
• Domestic water heated via a coil heat exchanger. Benefit: good heat layering within the boiler, good
thermal transfer.
• Zero-loss heat circuit regulation via an electrically actuated zone valve (1N ~ 230 V; 3 Watt)
with short heating up times (patent pending). This is why an electrical power supply at
1N ~ 230 V is necessary for the connection of a storage tank from the FSN or FSN-E type series.
• Elegant base to cover the connections, which is fitted with a service flap for better accessibility.
