3 Technical description

3.1 General description

BL 150...500 are high performance independent domestic hot water tanks.

DHW calorifiers BL 150...500 can be connected to central heating boilers used for heating domestic hot water.

Main parts:

4 The tanks are made of high quality steel lined with food quality

standard enamel vitrified at 850°C, which protects the tank from corrosion.

4 The heat exchanger welded into the tank is made of smooth

tubing, the external surface of which, which is in contact with domestic water, is enamelled.

4 The appliance is insulated by CFC-free polyurethane foam, which

reduces heat losses to a minimum

4 The insulating material can be easily detached from the tank. This

measure facilitates the recycling of materials.

4 The tank is protected against corrosion by a magnesium anode

which should be checked every 2 years and replaced if need be. The tanks with the greatest capacity (BL 300, BL 400, BL 500) are fitted with 2 protection anodes.

4 The impressed current anode and the shielded

electrical resistor cannot be fitted simultaneously.

4 Respect the recommended anode / electrical resistor

combinations as the electrical resistor is combined with a magnesium anode which, with the anode in the top section already in place, is calculated to protect the enamelled tank correctly.

4.3 Choice of the location
