What Is A Double-Wall Heating Oil Tank?
Homes in the eastern United States commonly use heating oil as fuel. It is stored in a tank installed on the property and pumped into the boiler or furnace to begin heat production. Consider getting a double-wall heating oil tank when you need an oil tank replacement. Keep reading to learn all you need about double-wall oil tanks, including their benefits and reasons a homeowner might choose to use one.
What Is A Double-Wall Heating Oil Tank?
A double-wall heating oil tank is a fuel storage tank with an inner tank surrounded by a secondary outer tank. The interstitial space is the space between these two tanks. It is a barrier to prevent spills or leaks from the inner tank from entering the environment.
The interstitial space is sealed. It also has alarms and sensors to monitor leaks and alert the owner of any problems. This space will contain the leak in case one occurs and keep it from entering the environment.
The double-wall tanks also have a “spill bucket.” This device is a small container inside the interstitial space to collect leaks or spills. This adds an extra layer of protection against leakage.

How Does A Double-Wall Heating Oil Tank Work?
The inner tank stores the fuel, while the outer tank acts as a secondary containment barrier. If the inner tank has a leak or spill, the interstitial space between the two tanks will contain it. This way, fuel doesn’t enter the environment and cause damage.

Benefits Of A Double-Wall Heating Oil Tank
Double-wall heating oil tanks provide several advantages over single-wall tanks. The most significant of which is the additional protection from leaks and spills. The secondary containment barrier has an extra security level that a single-wall tank does not have.
Another advantage of a double-wall heating oil tank is that it is longer-lasting and more durable. Its outer tank can be made of high-density polyethylene (HDPE). This material is durable, UV-resistant, and can withstand extreme weather conditions. So, double-wall tanks are an excellent option for outdoor installations.
Double-Wall Heating Oil Tank FAQs
Here are several frequently asked questions about double-wall heating oil tanks:
Are Double-Wall Heating Oil Tanks More Expensive Than Single-Wall Tanks?
Double-wall heating oil tanks are usually costlier than single-wall tanks. However, the additional protection from leaks and spills and higher durability may make it worth the extra cost in the long run. Several reasons make double-wall heating oil tanks usually more expensive than single-wall tanks:
- Materials used to make double-wall tanks are more expensive. The inner tank is constructed using the same materials as single-wall tanks. However, the outer tank is made of high-density polyethylene (HDPE), which costs more than standard plastic or steel used in single-wall tanks.
- Double-wall tanks have a more complex manufacturing process. The inner and outer tanks are constructed separately and then linked together, adding to the overall cost. Also, the interstitial space between the two tanks will be sealed and tested for leaks, which adds to the production cost.
- Double-wall tanks are more complex to install than single-wall tanks. They require proper leveling, and the interstitial space needs leak monitoring, which can add to the overall installation cost.
- Double-wall tanks have a higher initial cost since they are more durable and longer-lasting. However, they are considered a long-term investment because they may save you money in the long run by avoiding costly repairs and replacements.
Can I Install A Double-Wall Heating Oil Tank Indoors?
Yes, double-wall heating oil tanks can be installed inside. You should make sure the tank is placed in a well-ventilated space, preventing fumes buildup. This way, you can install double-wall heating oil tanks indoors.
Following the manufacturer’s instructions is crucial when installing a double-wall heating oil tank indoors. Make sure that you also comply with local building codes and regulations. Proper ventilation is required, like installing a pipe to vent the fumes outside so your home doesn’t accumulate dangerous fumes.
Keep in mind that indoor installation may need additional safety measures. These include installing a spill containment tray to contain all potential leaks or spills.
It is best to consult an HVAC professional who has extensive experience with heating oil tank installation. They can provide you with the best advice and ensure your safety. They will also make sure to comply with the regulations.

Are Double-Wall Heating Oil Tanks Required By Law?
Depending on the state and local jurisdiction, there are different regulations on double-wall heating oil tanks. The law in all areas doesn’t require double-wall heating oil tanks, but many states have rules requiring secondary containment for fuel storage tanks.
Some states or cities may have provisions requiring new tanks to be double-walled, while other regions may only need them for replacing tanks. Some regulations may mandate that existing single-wall tanks be retrofitted with secondary containment, like adding a secondary containment tray or installing a double-wall tank.
It is best to check with your local government agency or an expert who knows the area’s regulations. Doing so ensures that your tank complies with the law and that your fuel storage is safe and secure.
Conclusion
A double-wall heating oil tank provides extra protection from leaks and spills in your fuel storage tank. It provides advantages like better durability and secondary containment, making them an excellent option for those who require a replacement for their current oil tank. They may be more expensive than single-wall tanks, but the increased protection, durability, and overall peace of mind make double-wall heating oil tanks worth the investment down the line.
