Many parts make up your fuel tank, but you still need to know what they are called and what they are used for. We will see together the technical terms that are good to know in order to better use and maintain your installation.

1) The police valve

The police valve is used to stop the oil supply to the boiler if necessary. If your tank has a capacity greater than 1500 litres, a manually operated police valve must be installed on the pipe that supplies the equipment used.

2) The deposit

When the fuel level drops over time, condensation on the inside walls of the tank causes oxide particles to fall to the bottom. To avoid burner failure or tank damage, annual maintenance by a professional is mandatory.

3) The vent

It allows the permanent maintenance of the atmospheric pressure inside the fuel tank. The diameter of the vent pipe must be at least half the diameter of the filling line. The orifice shall open to the open air above ground level, at a point visible as far as possible from the delivery point.

4) The flexobloc

It is a flexible oil suction and return system with a check valve to prevent the fuel from returning to the tank once it has been sucked in.

5) Degassing

The degassing step, which is essential before neutralisation, consists in removing the heating oil vapours suspended in the oil tank, by suction and then by ventilation. This must first be emptied and cleaned of fuel oil residues.

6) Neutralisation

It must be carried out within 48 hours of degassing. This step makes the fuel tank permanently unusable. In the case of an underground tank, the filling is usually done with sand or concrete. For an above-ground tank, the tank is usually cut to size to be put out of service.

7) The manhole

Opening that allows a man to pass through the tank for inspection and maintenance.

8) The suction strainer

Device installed in the fuel tank that allows the fuel to be sucked in without sucking up any residues that may be present at the bottom of the tank. The fuel oil used for combustion is therefore less loaded with sediment, thus improving the boiler’s efficiency.

9) Storage

It depends on the estimated consumption for a heating season. Storage is generally renewed 2 to 3 times a year. The calculation formula generally used is as follows: consumption in litres of fuel oil per year = 120 to 180 x plant power (in kW).

10) The gauge

The gauge allows you to accurately measure the amount of fuel remaining in the tank, in order to estimate your consumption and the date of the next filling. The quantity of fuel oil in the tank is expressed in litres or as a percentage of the tank capacity. Thanks to the Fuel-it connected sensor, you can be alerted directly on your phone, computer or tablet.
