Determine the Residential Heating Oil Tank Size for Your Home and View This Oil Tank Size Chart to Determine How Much Oil You Need to Order.

Heating oil is widely used in the U.S to keep homes warm in the winter. If you have recently moved into a new home or are in the process of building one, chances are you may be wondering what the size of the heating oil tank is. Having an idea about fuel oil tank sizes is the key to keeping your home warm in the freezing temperatures of winter.


Residential Heating Oil Tank Sizes

Residential heating oil tank sizes range from 220 gallons to 1,000 gallons, but the average size used in homes is 275 gallons. The standard oil tank size comes in two basic shapes: oval and cylindrical.

Oval Tanks

Oval tanks can be installed either horizontally or vertically. The width, height, and length of a tank can give you a good estimate of its storage capacity. If it is 44 inches wide, 27 high and 60 inches long (measured horizontally), then it has a capacity of 275 gallons. If it is 44 inches wide, 27 inches tall and 72 inches long (measured horizontally), then it has a capacity of 330 gallons. The larger the dimensions, the greater the storage capacity.

Cylindrical Tanks

Cylindrical tanks are installed horizontally. Again, it is easy to guess their size by looking at their dimensions. If a tank is 60 inches long and has a diameter of 38 inches, then it has a capacity of 300 gallons. If it is 65 inches long and has a diameter of 48 inches, then it has a capacity of 500 gallons. A tank with the same diameter but is 130 inches long can hold 1000 gallons of oil.


The size of home heating oil tanks is determined by the size of the home. Larger homes require bigger oil tanks because there is more space to heat up. As mentioned earlier, an average sized home needs a tank of 275 gallons. If you have a small home, then a 220-gallon tank may be enough to heat up your home. Large homes may require a 1,000-gallon tank.


Types of Heating Oil Tanks

There are two types of heating oil tanks: single skin tanks and double skin bunded tanks. As you may have guessed, a double skin bunded tank consists of an inner tank inside a larger tank. This ensures that the oil will not spill out if a crack appears in the inner tank, which is where the oil goes in. The outer tank serves as a protective layer.


All new heating tanks are required to have labels on them that state the amount of oil they can hold. But old tanks may not have such labels. One way to find out a tank’s capacity is to measure its dimensions. Another way is to fill an empty tank with water, which gives you the exact amount of oil it can hold.
