In the eastern United States, many homes depend on heating oil as their primary heating fuel. This oil is in an on-site tank and transferred to the furnace or boiler to generate warmth. For homeowners contemplating a replacement of their existing oil tank, opting for a double-wall heating oil tank model offers several advantages. This article by Lombardi Energy explores the characteristics of double-wall oil tanks, their benefits, and why a homeowner might select one.

Understanding Double-Wall Heating Oil Tanks

A double-wall heating oil tank has two concentric layers: an inner and an outer tank. The gap between these layers, known as the interstitial space, functions as a protective barrier, blocking any potential leaks from the inner tank from reaching the outside environment.

This interstitial space is tightly sealed and equipped with monitoring systems, including alarms and sensors, to promptly alert the owner of any leakage. In the event of a leak, this space effectively traps the leaked substance, safeguarding the environment from contamination.

Double-wall heating oil tanks have a device known as a “spill bucket.” Positioned within the interstitial space, this small container captures any leaks or spills, offering an extra defense against potential leakage.

How a Double-Wall Heating Oil Storage Tank Functions

The double-wall heating oil tank operates with a simple yet effective mechanism. The inner tank holds the fuel, while the outer tank serves as a secondary containment barrier. Should there be any leakage or spillage from the inner tank, the fuel ends up in the interstitial space between the two tanks. This design effectively prevents the fuel from escaping into the environment and causing harm.

Advantages of Double-Wall Oil Tanks

Double-wall heating oil tanks present numerous advantages over their single-wall counterparts. The most noteworthy advantage is the enhanced protection against leaks and spills provided by the secondary containment barrier. This feature provides additional security that is absent in single-wall tanks.

Furthermore, double-wall heating oil tanks are inherently more robust and have a longer lifespan. The outer tank can be constructed from high-density polyethylene (HDPE), a material known for its durability, resistance to UV light, and capability to endure harsh weather conditions. These attributes make double-wall tanks an excellent choice for outdoor installations.

Double-Wall Heating Oil Tank Installation Guide

Here’s a step-by-step guide to properly installing a double-wall heating oil tank.

  1. Location Selection: Choosing the most suitable location for your double-wall heating oil tank is crucial. Ensure the spot is easily accessible for fuel delivery and routine maintenance, adheres to local safety regulations, and is away from potential environmental hazards such as flooding or overhead power lines.
  2. Site Preparation: Preparing the site for installation includes leveling the ground and, if necessary, constructing a concrete pad or installing stable pavers. This foundation is essential for supporting the tank’s weight and preventing movement over time.
  3. Oil Tank Placement: After the site is adequately prepared, the tank is precisely placed to ensure it remains stable and level, which is vital for its proper functioning. Professional installers then connect the tank to your home’s heating system, carefully following all safety standards to ensure the system is completely sealed and leak-proof.
  4. Safety Checks and Final Setup: Technicians carry out a comprehensive series of checks post-installation. They test for any leaks in the interstitial space and verify the functionality of all alarms and sensors. This meticulous setup ensures the tank operates safely and efficiently, primed to provide reliable heating for your home.

Inspection & Monitoring of Double-Wall Fuel Oil Tanks

Consistent inspections and thorough monitoring are necessary to guarantee the ongoing reliability and safety of double-wall heating oil tanks. Here’s an overview of the vital procedures involved:

Routine Heating Oil Tank Inspections

It’s crucial to have regular professional inspections to check the structural condition of both the inner and outer tanks of a double-wall heating oil system. These inspections are essential for identifying potential problems early, helping prevent minor issues from becoming severe failures.

Oil Tank Monitoring Systems

Contemporary double-wall tanks have sophisticated monitoring systems that continuously monitor the interstitial space—the gap between the inner and outer tanks. These systems can detect even minor irregularities or the presence of oil, signaling a potential leak.

Home Heating Oil Tank Alarm Systems

Integrated alarm systems are a standard feature in these tanks, designed to notify homeowners of any leaks or structural issues immediately. These alarms are vital for quick action, effectively reducing potential environmental and safety risks.

Oil Tank Compliance Checks

Double-Wall Heating Oil Tank FAQs

frequently asked questions spray painted on concrete depicting oil tank questions

Here are some commonly asked questions about double-wall heating oil tanks:

Do Double-Wall Heating Oil Tanks Cost More Than Single-Wall Tanks?

Double-wall heating oil tanks usually cost more than single-wall tanks. However, their added benefits, such as superior protection against leaks and spills and enhanced durability, offset this higher initial expense. These factors make the additional cost worthwhile over the long term.

Firstly, the construction materials for double-wall tanks cost more. The inner tank uses the same materials as single-wall tanks; however, the outer tank is made from high-density polyethylene (HDPE), which is pricier than the steel or standard plastic used in single-wall tanks.

Secondly, the manufacturing process for double-wall tanks is more intricate. The manufacturer builds the inner and outer tanks separately and then assembles them, which increases the total cost. They also seal and check the interstitial space between the tanks for leaks, raising production expenses.

Third, the installation of double-wall tanks is more complex than that of single-wall tanks. These tanks need precise leveling, and technicians must continuously monitor the interstitial space for leaks, increasing installation costs.

Lastly, double-wall tanks are designed to be more durable and have a longer lifespan. Although they represent a larger initial investment, they can bring long-term savings by reducing the need for costly repairs and replacements.

Is It Possible to Install a Double-Wall Home Heating Oil Tank Inside a Home?

Absolutely. Double-wall heating oil tanks can be installed indoors. However, it is crucial to install the tank in a well-ventilated area to prevent the buildup of fumes, thus allowing for safe indoor installation.

When setting up a double-wall heating oil tank indoors, it’s essential to adhere strictly to the manufacturer’s instructions and local building codes and regulations. Additionally, ensuring proper ventilation, such as employing a pipe to vent fumes outdoors, is vital to prevent the accumulation of hazardous fumes within the living space.

It’s also important to consider that indoor installations might necessitate extra safety precautions, such as the placement of a spill containment tray to manage any potential leaks or spills.

It is always advisable to consult with a professional experienced in heating oil tank installations to obtain the best guidance and ensure safety and regulatory compliance.

Is It Legally Required to Use Double-Wall Heating Oil Tanks?

The requirement for double-wall heating oil tanks is dependent on state and local regulations. While not universally mandated, many states have laws that necessitate secondary containment for fuel storage tanks.

In certain regions, regulations may require new tanks to be double-walled, while other areas might apply this requirement only to replacement tanks. Additionally, some rules may mandate upgrading existing single-wall tanks with secondary containment measures, such as installing a double-wall tank or adding a containment tray.

It is advisable to consult with your local government agency or a professional familiar with the specific regulations in your area regarding tank installation. This ensures that your tank meets legal standards and that your fuel storage is safe and compliant.

Conclusion

A double-wall heating oil tank is an advanced type of fuel storage solution that enhances protection against leaks and spills. It boasts increased durability and secondary containment, making it an excellent choice for homeowners looking to upgrade their existing oil tank. Although these tanks are generally more costly than single-wall options, their superior protection, extended lifespan, and overall peace of mind often justify the investment over time.
