Expansion Tank
Closed expansion tanks are connected to heating installation in the boiler room. In the water
circuit entering into tank, there is a membrane (bubble) based on EPDM, and air is pumped
between the tank and membrane. Expanded water fills into the membrane and compresses the
air. Then, when pressure drop and water decrease occur due to cooling down on system side,
compressed air pushes the water inside membrane back to system again and completes the
missing water. It is required to use with appropriate safety valve. Closed expansion tanks can
only be used in liquid and gas-fueled heating systems provided automatic control mechanical
combustion.
Fuel Selection
Except for Natural Gas, in the event of using LPG or LNG;
Burner settings must be set in accordance with the specifications of manufacturer company.
Fuel tank and lines, should be organized in accordance with the specification of the company
where fuel is procured.
Necessary Operating Pressure Of Boiler As Per Floor Height
Boiler selection in terms of operating pressure must be done as follows.
Floor Height Pressure (ATÜ)
1 - 7 3
7 - 10 4
10 - 13 5
13 - 15 6
