Your fuel oil tank is equipped with a whistle located in the vent pipe. As oil enters your tank, the air that is present inside your tank is being displaced through a small vent.
Where should the vent alarm be installed on an oil delivery system?
A vent alarm is a small device, usually a tube, which is typically installed between your tank and the vent pipe. It signals that the tank is full, thereby minimizing the chance of overfilling.
How do you clean an oil tank whistle?
Pour half a gallon of mineral spirits (paint thinner) down the vent line. This should wash away the softened deposit and leave a clean whistle. In case it is not obvious, let us point out that these things should not be poured into the vent line just before filling the tank.
Why does my oil tank whistle?
When oil depletes inside the tank, air occupies its place. During oil delivery, the air is pushed out by the oil. The tank is fitted with a vent alarm that produces a whistling sound when air is being pushed out. It is a crucial signal that can be heard by everyone nearby, including the delivery personnel.
Do all oil tanks have a whistle?
The Department of Labor & Industry requires that all indoor oil tanks with outside fills have a Whistle Vent to prevent overfill. This audible alarm is mandatory on any oil tank where the tank is not visible during filling such as in a basement.
Do heating oil tanks need to be raised?
We recommend your oil tank is installed outside, above ground within a secondary containment system. Position your tank to minimise risk of pollution and maximise its security. Consider placing it in view of a frequently occupied room so you can keep an eye on it.
How deep should an oil pipe be buried?
Oil feed pipes should be buried at least 300mm clear of other underground services such as water and electricity. Joints in buried pipe work should be avoided if at all possible.
Do oil tanks make noise?
As oil flows into the tank, air from the tank gets pushed back out. As the air goes through the vent alarm–located between your tank and vent pipe–it makes a whistling sound. If the diameter is too narrow, this will allow excessive pressure to build up inside the tank during filling, which can cause a tank rupture.
Can you fill an oil tank to the top?
The exact level of when to fill your tank up depends on the size of your oil tank. We recommend that you phone for a top-up when your tank reaches around a quarter full. This way you will avoid running out and your boiler will be safe.
Which pipe is the fill pipe on an oil tank?
The fill pipe extends from the top of the oil tank, through the exterior wall, and outside of the house. There is a cap that screws in place to keep the fill pipe closed. The vent pipe also extends up and out of the house, and allows air to escape as the oil tank is being filled.
What is a vent whistle?
A type of audible overfill prevention device used with aboveground tanks that produces a high pitched whistling sound continuously during the fuel delivery and stops when the alarm level is reached.
How far does an oil tank have to be from a house?
Your tank needs to be a specific distance away from non-fire rated parts of your property; for example, 1.8m away from eaves, sheds and gazebos and 760mm away from boundary fencing. You should not place a bunded oil tank within 1.8m of the doors, windows or any other construction openings.
How do I know if my oil tank needs to be replaced?
Signs of this can include: Wet spots around the oil tank. Puddles of oil present near the oil tank, or along its piping. A persistent odor of heating oil in or near your home (you should only notice this smell at the beginning of the year if your tank and oil furnace are in good condition!).
Do oil tanks need planning permission?
If your house is a listed building then you will need planning permission to install a new oil tank. The other building regulations requirements for oil tanks you need to be aware of include: If the tank is to be stored above the ground, it will need a protective shield to guard from fire.
Does an oil tank need to be higher than the boiler?
Raising the tank so that the bottom outlet is higher than the boiler inlet will allow gravity to feed the fuel directly to the boiler. If located at ground level, a bunded plastic tank will require an internal flexible suction pipe to draw the fuel oil up to a top outlet, which is factory fitted within the outer bund.
How far away can oil tank be from boiler?
The base should also ordinarily extend a minimum of 300mm beyond the widest points of the tank and fully support the underside of the tank in its entirety.Fire Safety. Adjacent Structure Distance mm Distance inches Oil boiler flues 1800mm 6′ Non-fire rated boundary 760mm 2′ 6” Foliage and vegetation 600mm 2′.
Are Single Skin oil tanks legal?
Single skin oil tanks can still be suitable in certain domestic situations though. The tank must not be located where oil spills could run into an open drain or a loose manhole cover. The tank must not be located within 50 metres of a drinking water source, for example wells, boreholes or springs.
Why is my oil burner so loud?
Shut-down oil burner rumbling noises are usually traced to air leaks into the oil piping system (expanding air as oil pressure falls pushes more air out of the nozzle for incomplete combustion), improper electrode settings, or a defective fuel unit (oil pump) that doesn’t shut off cleanly.
