Tank Installation

Oil Tank Installation Services on Long Island

A new oil tank is one of the best investments you can make in your home's heating system. Today's tanks are engineered to resist the corrosion and rust-through failures that plague older steel tanks, and a professional, code-compliant installation protects your home for decades to come.

Domino Fuel installs new oil tanks for homes across Suffolk and Nassau County, indoors and out. We help you choose the right tank and size, place it for easy delivery and inspection, and connect it safely to your heating system. If you are taking out an aging tank first, we pair installation with same-day oil tank removal so you are never left without heat.

Choosing Your Tank

Choosing the Right Oil Tank for Your Home

The best tank depends on your home, your usage, and where the tank will live. We help you weigh the options.

Tank Sizing

Residential tanks most commonly hold 275 or 330 gallons. We help you choose a size that matches your heating demand and delivery schedule, so you are not refilling constantly or paying for capacity you will never use.

Indoor and Outdoor Placement

Basement tanks stay protected from the weather, while outdoor tanks free up space inside. We assess clearances, the fill and vent lines, and access for delivery, then position your tank for safe, easy refills. It is also the ideal moment to add a vent alarm installation and a fresh oil tank gauge replacement so every future delivery is safe and accurate.

Tank Brands We Carry

Oil Tank Brands We Install on Long Island

We install the leak-resistant tanks Long Island homeowners trust. Each one is a modern upgrade over the bare steel tanks of decades past.

01 / Granby

Granby EcoGard

Granby's premium leak-protection tank. A second steel bottom and a corrosion-resistant interior guard against the rust-through failures that cause most basement leaks, making EcoGard our go-to upgrade for worry-free heating.

02 / Granby

Granby Standard

The dependable, industry-standard residential steel tank. Built to UL specifications and trusted in Long Island basements for decades, the Granby Standard is a cost-effective, reliable replacement on a sound budget.

03 / Roth

Roth Double-Wall

A leak-resistant inner tank inside a galvanized-steel outer shell, the Roth holds 110% of capacity if the inner wall is ever breached. It is lightweight, compact, and backed by a strong manufacturer warranty.

Our Process

The Oil Tank Installation Process

A clean, professional install you can count on.

1. In-Home Assessment

We evaluate your space, heating demand, and the best tank type and placement, then give you a free written quote.

2. Removal of the Old Tank

If you are replacing an aging tank, we handle oil tank removal first, or set a temporary oil tank installation if the project needs more time, so your heat stays on.

3. Code-Compliant Installation

We set the new tank, connect the fill, vent, and supply lines, install safety accessories, and test the system before we leave. For a like-for-like swap, see our dedicated oil tank replacement service, or explore the full picture on our oil tank services hub.

Tank Sizes

Common Oil Tank Sizes for Long Island Homes

Choosing the right capacity balances how often you want deliveries against upfront cost and available space. These are the sizes we install most.

275-Gallon Tank

The most popular and common size for homes, and a good balance between storage capacity and price. It fits most basements and the side of a house.

550-Gallon Tank

A common upgrade for larger homes with higher fuel demand. The added capacity means longer intervals between fill-ups.

100-Gallon Tank

A fit for smaller homes or tight spaces. It has a lower upfront cost but needs more frequent filling.

Commercial Capacities

For businesses we install larger tanks, commonly 1,000 and 2,000 gallons, with specialized capacities available for bigger facilities. Fire code, storage needs, and property size all help determine the right size, and we size every job to your building.

Cost

How Much Does Oil Tank Installation Cost on Long Island?

There is no flat-rate price, because every installation is different. The cost depends on the tank and brand you choose, its size, indoor or outdoor placement, and whether an old tank needs to be removed first. Rather than quote a one-size price, we keep it simple: every homeowner gets a free, no-obligation estimate up front, with no hidden fees. Call (631) 779-3196 or request a free quote and we will give you an exact price for your situation.

FAQ

Frequently Asked Questions

Answers to the questions Long Island homeowners ask us most.

1How much does a new oil tank installation cost on Long Island?

Cost depends on the tank brand and size, indoor or outdoor placement, and whether an old tank needs to be removed first. We provide a free written estimate so you know the full price before we start.

2What size oil tank do I need?

Most Long Island homes use a 275- or 330-gallon tank. The right size depends on your heating demand and how often you want deliveries. We help you choose during your free assessment.

3Should my tank go in the basement or outside?

Both work well. Basement tanks are protected from the weather and easy to monitor, while outdoor tanks save indoor space. We will recommend the best placement for your home and ensure proper clearances.

4Which oil tank brands do you install?

We install Granby EcoGard, Granby Standard, and Roth double-wall tanks, all leak-resistant, code-compliant options with strong warranties.

5Can you remove my old tank and install the new one together?

Yes. We routinely remove the old tank and install the new one in a single visit, and can set a temporary tank if the project needs extra time so your heat is never interrupted.

6Do new oil tanks come with a warranty?

Yes. Manufacturer warranties vary by brand and model, and Roth double-wall tanks in particular carry strong coverage. We also back our installation workmanship.

7How long does an oil tank installation take?

Most residential installations are completed in a day, including connecting and testing the system. A combined removal and installation usually finishes the same day as well.
