Oil Tanks: Types and Materials

Oil tanks come in various types and are typically made of different materials.

Above-Ground Oil Tanks: These tanks are installed on or above the ground surface. They are relatively easy to install and inspect, making them a popular choice for many homeowners.
Underground Oil Tanks: Buried underground, these tanks are hidden from view. While they offer aesthetic benefits, they require more complex installation and maintenance procedures.
Materials: Oil tanks are commonly made from steel or fiberglass. Steel tanks are durable but susceptible to corrosion over time. Fiberglass tanks are corrosion-resistant and offer longer lifespans.

Choosing the Right Size

Selecting the right size of the oil tank is crucial to ensure you have an adequate fuel supply without excessive refills. Factors to consider include the size of your home, climate, and heating system efficiency. A reputable heating professional can help you determine the appropriate tank size based on your specific needs.

Oil Tank Maintenance

Safety is paramount when it comes to maintaining your oil tank.

Regular Inspection: Regardless of tank type, regular inspections are crucial to detect signs of wear, corrosion, or leakage. Annual inspections by a certified technician are recommended.
Warranty: Most homeowner insurance and oil dealer service policies do not cover oil tank replacement. Consider a Tank-Guard Warranty Plan to help protect your tank’s longevity!
Environmental Responsibility: Proper disposal of old tanks and promptly addressing leaks is essential to protect the environment. Many regions have strict regulations regarding the decommissioning of old tanks.
Insurance and Liability: Ensure your installation complies with local codes and regulations to avoid any insurance or liability issues.

Tank-Guard - Affordable Oil Tank Warranty Protection For Your Home

Protect your tank against damaging internal corrosion, plus a $2,000 tank replacement warranty!

Standard steel heating oil tanks are strong and durable but, like most things, they eventually need to be replaced. Internal corrosion, caused gradually over time by natural condensation, is usually the reason. Most homeowner insurance and oil dealer service policies do not cover oil tank replacement. With Hillside’s proactive annual TANK-GUARD® Oil Tank Protection Program, qualifying tanks are protected against damaging internal corrosion with an effective liquid corrosion inhibitor to reduce the risk of tank failure. Plus, you will be protected financially with a generous tank warranty if your tank should need to be replaced while it is registered on our program.

“When my oil tank leaked, the TANK-GUARD® warranty covered most of the cost to replace it. Many thanks.”

“I’m so glad my oil dealer suggested TANK-GUARD®. My tank leaked last week and the crew who came to replace it were neat and very professional. My copay was only about $200 – paying for the whole cost myself would have been a real hardship.”

“I like feeling that TANK-GUARD® is good for my oil tank and that I have the warranty protection as well.”

 recommends  This was our first time using this company & we will absolutely be using them again. Our technician was extremely knowledgeable & friendly. He really took the time to explain everything to us & didn’t try to sell us something new. I would 100% recommend this company to anybody in the area for any of your heating and cooling needs.

 recommends  My technician, Michael Fields II, assures me that all is well with my systems. I trust his assessment so feel confident that we will stay cool this summer and be warm this winter. He was polite, friendly, considerate, and EXTREEMLY popular with my pets. Bodhi and Baxter, one of the 2 dogs and one of the 2 cats, were very happy to follow him everywhere in the house. All 4 pets waited for him each time he went outside and made sure to get pets upon his return. I love that Michael came back this year and continues to take care of my systems as his father did before him. Very cool! Many thanks, and the crew looks forward to his return!

   Justin from Hillside came out to do a tune-up on our heat pump with auxiliary oil and replace a fuel gauge. He was very helpful in answering questions and service was fast, professional, and affordable.
