Roth double-wall heating oil tanks are the safest residential oil tanks you can buy on Long Island, pairing a seamless high-density polyethylene inner tank that cannot rust with a galvanized steel outer shell that holds 110% of the inner tank. If the inner tank ever failed, the outer wall contains the oil: no spill, no soil contamination, no cleanup. An optical leak alarm gives early warning.
Why homeowners choose Roth:
Roth backs every double-wall tank with a 30-year manufacturer warranty* and up to $2 million in clean-up insurance*, the longest coverage in the residential oil tank industry. A typical steel tank carries a 1 to 5 year warranty, so a Roth protects your home for decades longer than the tank it replaces.
That coverage matters on Long Island, where a leaking tank can mean a five-figure soil cleanup. With a Roth, the double-wall design contains a leak and the manufacturer stands behind the tank for 30 years. As an authorized Roth dealer, Domino Fuel installs every tank to Roth's specifications, so your installation qualifies for the full manufacturer coverage.
*Manufacturer's warranty and clean-up insurance are provided by Roth and subject to Roth's terms and conditions. See roth-america.com for full details.

Here is a quick look at the main Roth oil tank models we install and service on Long Island, so you can compare construction and capacity at a glance.
| Model / Series | Construction | Capacity | Best For |
|---|---|---|---|
| Roth DWT 110 | Galvanized steel outer + HDPE inner | 110 gal | Tight spaces, lower usage |
| Roth DWT 165 | Double-wall (steel + HDPE) | 165 gal | Smaller homes |
| Roth DWT 275 | Double-wall (steel + HDPE) | 275 gal | The standard residential size |
| Roth DWT 400 | Double-wall (steel + HDPE) | 400 gal | Larger homes, longer fills |
| 2× DWT 275 multi-tank | Two double-wall tanks, cross-feed piping | 550 gal | High-usage homes, fewer deliveries |
| 3× DWT 275 multi-tank | Three double-wall tanks, cross-feed piping | 825 gal | Large properties, stock up before winter |
Every model is available for indoor or outdoor above-ground installation, holds 110% of the inner tank in the outer shell, and includes an optical leak alarm. In a multi-tank setup, each tank carries its own warranty.
Most oil tank failures on Long Island are caused by internal corrosion in single-wall steel tanks. Roth's design eliminates that risk entirely. Here is how the two compare:
| Feature | Roth Double-Wall | Traditional Steel |
|---|---|---|
| Wall construction | Double-wall (inner + outer) | Single-wall |
| Corrosion resistance | Polyethylene, cannot rust | Rusts from the inside out |
| Leak containment | Outer wall catches leaks | Leaks directly to floor or soil |
| Fittings below oil line | None | Bottom fittings can leak |
| Manufacturer warranty | 30 years* | 1 - 5 years typical |
| Typical lifespan | 30+ years | 15 - 20 years |
| Biofuel compatibility | B20 ready | Varies by manufacturer |
Prefer a steel double-wall option? We also install Granby tanks, and we will recommend whichever fits your home and budget best.
Every Roth oil tank we install is sized to your home, most homes use the DWT 275, and placed to code in the basement or outdoors above ground. Because a Roth is about 55% lighter than a comparable steel tank, it fits through standard basement doors and bulkheads that rule out a welded steel replacement, and every fitting mounts on top of the tank, so there are no bottom connections to corrode and leak.
We set the oil supply line, vent whistle, and leak monitoring, pull the Suffolk or Nassau permits, and safely remove and dispose of the old tank. A tank is only as safe as its install, so we mount it securely and test before we leave. See our oil tank installation page or all oil tank services.
Surface rust, a stuck gauge, a silent vent whistle, or weeping at a fitting? Our technicians service Roth oil tanks and the lines, gauges, and alarms that go with them, with fast response across Suffolk and Nassau County.
We can also add a Wi-Fi tank gauge or a vent alarm. Catching tank problems early prevents costly leaks and cleanups.
When a steel tank is sweating, rusting, weeping, or simply old, replacing it is far cheaper than cleaning up a leak. We will inspect it honestly and, if it is time, install a new double-wall Roth tank, typically $3,490 to $3,890 installed, and remove the old one.
We handle the permits, oil transfer, removal, and disposal, all with a free estimate up front. See our oil tank replacement and removal pages.
A Roth's polyethylene inner tank cannot rust, so problems usually show up at the fittings, gauge, and alarms rather than the tank itself. Catching them early usually means a smaller, cheaper fix. Call us if your Roth oil tank shows any of the following:
Repair is not always the smart money. It is usually time to replace when you see:
We stock or quickly source the parts that wear out most on Roth double-wall tanks, from leak alarms to top fittings, so repairs and tune-ups stay fast:
