Heating oil burns slowly and efficiently to heat your home in the winter. It is not as volatile as gasoline, making it safer for your household. If you’re on the market for a new heating system, you’ll find that you can install a tank that’s above- or underground. If you’re still on the fence about which to choose, here’s a guide that will help you make an informed decision. 

What’s the Difference Between Above-Ground & Underground Heating Oil Tanks?

An above-ground heating oil tank can be located either outdoors or indoors. When installed inside, it is usually found in the garage, basement, or utility room. An outdoor tank is typically at the side or rear of the home to minimize visibility. This also keeps it safe from automobile or lawnmower accidents.

An underground tank is often bigger than an above-ground one. It can be made from steel, but fiberglass is preferable to prevent rust and corrosion. This option must meet the Environmental Protection Agency’s standards for construction, design, and installation to lessen the negative impact on the environment.

Why Are Above-Ground Options More Popular?

Aside from having a lower upfront cost, an above-ground tank is better for the planet because there is less risk of pollution. Failure to maintain an underground heating oil storage tank may result in fines, since it affects the soil and surrounding groundwater. In the event of a leak, it is also easier to spot and repair the breach in an above-ground unit.

While underground tanks are insulated by soil, which helps keep the fuel liquid, above-ground tanks can also offer this protection. Installing the tank in an enclosed location, such as a basement or garage, regulates the temperature and prevents the heating oil from getting thick and gummy without using additives. 

Selecting an above-ground tank can also keep you ahead of changing state requirements. Although Connecticut currently permits underground oil storage, the state recently passed a law that will mandate above-ground tanks over the next few years. Choosing this storage method now saves you the time and cost of switching later.
