The heating oil gauge is a relatively simple device that measures how much oil or gas your furnace has left. However, it can be tricky to read in some cases like when the needle is stuck at “empty” and there are large amounts of mercury inside the glass chamber. Here’s a guide on how to read them properly!.
To read a heating oil gauge, first you need to know how the gauge works. The gauge has two glass tubes that are connected by mercury. One tube is filled with water and the other is filled with oil. When heat is applied, the temperature of the water in one tube increases while the temperature of the oil in the other tube decreases. That means that when you see liquid on both ends of a glass tube, it means that there’s too much pressure or too little pressure in your tank.
Nothing is more important than making sure you don’t run out of heating oil if you live in an oil-heated home. Even though you pay a premium for Automatic Heating Oil Delivery, you must check your home heating oil filter on a regular basis to avoid running out. We’ll go through the nuances of reading a typical float-style heating oil tank gauge as well as numerous different ways of monitoring your fuel oil tank in this article on “How to Read a Heating Oil Gauge.”
What Is a Heating Oil Gauge and How Do I Read It?
A traditional float-style gauge is used on the majority of fuel oil tanks. A hinge and an arm with a float are attached to the end of this fuel oil tank gauge. The amount of heating oil in the tank is shown by a little vial with a disc within. As the float drops, this disc shrinks.
To assess the level of a float gauge, look for tick marks on the plastic vial. Common descriptors include whole, 3/4, 1/2, and 1/4. When the tank is down, these gauges aren’t very precise since the base of the home heating oil tank is curved. Purchase heating oil online when it is around 1/4 full, as a general rule. This permits you to wait for the oil to come for a few nights before it runs out.
Several ‘experts’ recommend looking at the top of the disc where it aligns with a tick mark rather than the bottom. Simply look for where the center of the disc lines up with a tick mark to determine the level since these float gauges are much too inaccurate to distinguish such a difference.
Multiply the displayed level by the size of your fuel oil tank to approximate how much heating oil is in the container. For a 275-gallon tank, 1/4 full is 0.25 x 275 = 69 gallons. For a 330, 1/4 full is 0.25 x 330 = 82.5.
Most home heating oil tanks come with a pressure gauge for the boiler. The yellow disc inside may be used to determine the volume of the fuel oil tank. A fuel oil tank’s rounded bottom allows the gauge to move quicker from 1/4 to empty than it does from 1/2 to 1/4. As a consequence, reordering oil when the gauge shows 1/4 full is crucial to prevent a runout.
What is the accuracy of a float gauge for heating oil?
These aren’t exact heating oil tank gauges, so only use them to approximate how full a tank seems to be. These may wear out over time due to the moving mechanisms within. If you think your heating oil float gauge is stuck, just remove the plastic vial by yourself. With your finger, press the disc down. The disc should easily slide down, then softly float back up and remain up if the gauge is not jammed, indicating that the arm is free to move.
Simply rotating within the fuel oil tank might cause a heating oil floating gauge to get caught. This may happen over time, causing the float to get trapped against the tank’s side and unable to move.
In a single day, how much heating oil will I require?
This is an excellent issue to ponder as you prepare to buy your next supply of heating oil. The first thing to consider is whether you’re using oil just for heating or for heating and hot water. If you heat your water using heating oil, you’ll be using it all year. In the summer, your water use may be as low as 1-2 gallons per day, while in the winter, it may be as high as 6 or more gallons per day. This is governed by your home’s size, insulation, and other factors. The lifespan of your heating system, as well as how well it is maintained, are important factors to consider.
The only way to really know how much oil is utilized on any given day is to install a device like the Smart Oil Gauge. The Smart Oil Gauge uses an ultrasonic sensor to detect the oil level every hour. The data is then plotted across time to provide consumption statistics.
Maintaining the optimum oil level necessitates the use of an oil level gauge. On the gauge, the 25°C level is typically noted, which is the right oil level at that temperature. If the oil level falls below the location of the radiator intake, flow through the radiator ceases, and the transformer overheats.
It’s critical to use the float gauge to accurately assess the level of your heating oil tank so you can determine the quantity of oil you’ll need for future usage.
Now that you seem to understand how to read a float gauge, bear in mind that it is just a rough estimate. When the tank is low, consider using a Smart Oil Gauge to get precise tank level readings. Now you know How to Read a Heating Oil Gauge and other important information.

Frequently Asked Questions
How do you read a heating oil gauge?
A: In order to read a heating oil gauge, one should first recognize the components of it. One must see that there is an input and output line on the left side in order to properly interpret what each means. The red zone typically represents the maximum amount allowed by law for home use without punishment from authorities.
How do you read oil level in oil tank?
A: There are several ways to do this. One way is by placing a funnel at the top of your oil tank and then pouring in some water into it, which will create an air bubble around the liquid that you can see through. Another way is with a hydrometer, which uses density measurements rather than sight to determine how much water has been added.
How do you know if your oil tank is empty?
A: If the oil in your engine is black, you might have an issue with your tank.
