What Is A Double-Wall Heating Oil Tank?

A double-wall heating oil tank comprises an internal tank enveloped by an outer tank, creating an interstitial space in between. This gap acts as a safeguard, thwarting leaks or spills from the inner tank from affecting the surroundings. The interstitial space is hermetically sealed and subject to continuous monitoring via alarms and sensors that promptly alert the owner to any issues. Should a leak occur, the interstitial space confines the leak, averting environmental contamination. 

These double-wall tanks incorporate a “spill bucket,” a container within the interstitial space that captures leaks or spills. It offers supplementary protection against potential leaks. Double-wall tanks provide added protection and a much better storage capability compared to single-wall tanks.

How Does A Double-Wall Heating Oil Tank Work?

A double-wall tank is an effective oil storage equipment. It works by using an inner tank and an outer tank. The inner tank is designated to store the fuel. The external tank serves as a secondary line of defense, acting as a safeguarding shield.

Should there be a leak or spill, the interstitial space between the two tanks comes into play. It captures any escaped fuel, acting as a strategic containment measure. By employing this containment approach, the likelihood of the fuel dispersing into the environment and inflicting damage is effectively thwarted.

Benefits Of A Double-Wall Heating Oil Tank

Double-wall heating oil tanks present numerous advantages compared to single-wall counterparts. The foremost advantage lies in heightened protection against leaks and spills. This is done by the supplementary containment barrier inherent in double-wall tanks. This added layer of security surpasses the capabilities of single-wall tanks. 

Double-wall heating oil tanks exhibit increased durability and longevity. The exterior tank of a double-wall variant can be made from high-density polyethylene (HDPE), a resilient and IV-resistant material capable of withstanding even the harshest weather conditions. This makes double-wall tanks an excellent choice for outdoor installations.

These tanks also offer extra convenience and comfort to homeowners. Without having to worry about leaks and malfunctions, homeowners can enjoy their homes with their loved ones.

Double-Wall Heating Oil Tank FAQs

Are Double-Wall Heating Oil Tanks More Expensive Than Single-Wall Tanks?

Although double-wall tanks typically carry a higher price tag, the additional safeguards, and features can justify the extra expense over time. The increased cost of double-wall tanks can be attributed to several factors.

  • The construction materials are costly. While the inner tank uses similar materials as single-wall tanks, the outer tank is fashioned from high-density polyethylene (HDPE). HDPE is a pricier substance compared to steel or standard plastic found in single-wall heating oil tanks. 
  • The manufacturing process is more intricate. It involves separate construction and subsequent joining of the inner and outer tanks, contributing to overall expenses. The interstitial space between the two tanks requires sealing and leak testing, further raising production costs. 
  • Installation is complex. It requires precise leveling of the tanks and ongoing monitoring of the interstitial space for leaks. This adds to the overall installation costs. 

Given the enhanced longevity and durability of double-wall tanks, they can be regarded as a long-term investment. They require a higher upfront cost but potentially offsetting expenses over time by avoiding costly repairs and replacements. The long-term savings, convenience, and peace of mind it brings homeowners make it an easy choice.

Can I Install A Double-Wall Heating Oil Tank Indoors?

A double-wall heating oil tank can be installed indoors. However, ensuring proper ventilation to prevent fume buildup is crucial. Installing a double-wall tank indoors is possible. You have to stick to the manufacturer’s guidelines and local building codes. Implementing adequate ventilation, possibly through a vent pipe to disperse fumes externally, is necessary to avert the accumulation of hazardous fumes.

The regulations pertaining to double-wall heating oil tanks vary across states and local jurisdictions.
