Which Roth Tank Size Do I Need?
Not sure which size fits your home? Here is how Long Island homeowners typically choose.
110-Gallon
Best for small spaces and supplemental heating
Ideal for high-efficiency condos, apartments, mother-in-law suites, seasonal cottages, and utility closets where a full-size tank will not fit. Popular in areas like Long Beach, Fire Island, and the East End.
Homes under 1,000 sq ft
View 110-gallon specs →275-Gallon
The standard for most Long Island homes
The go-to for 3-bedroom colonials, ranches, capes, and split-levels throughout Levittown, Hicksville, Smithtown, Massapequa, and most of Nassau and Suffolk. Available in standard and low-height models for basements with tight ceilings.
Homes 1,200 to 1,700 sq ft
View 275-gallon specs →400-Gallon
Maximum capacity for larger homes
Built for large colonials, waterfront properties, multi-zone heating systems, and multi-generational homes across the North Shore, the Hamptons, and South Shore estates. Fewer oil deliveries and better bulk pricing.
Homes 2,500+ sq ft

Why Homeowners Choose Roth Tanks
Over 3 million Roth tanks installed worldwide. The gold standard for residential oil storage.
Double-Wall Protection
Galvanized steel outer tank holds 110% of inner tank capacity. If the inner tank ever fails, not a single drop reaches the ground.
Optical Leak Alarm
Built-in visual alarm between the inner and outer wall alerts you immediately if any moisture is detected. No electronics needed.
Corrosion-Proof
Seamless blow-molded HDPE inner tank will never rust. Unlike steel tanks that corrode from the inside out, Roth tanks are immune.
50% Lighter
Up to 50% lighter than 12-gauge steel tanks with removable base. Easier to maneuver through tight basements and doorways.
Roth Double-Wall vs Steel Oil Tanks
Still on the fence? Here is how a Roth stacks up against the standard steel tank sitting in most Long Island basements.
| Feature | Roth Double-Wall | Standard Steel Tank |
|---|---|---|
| Warranty | 30-year limited | 1 to 2 years typical |
| Leak Protection | 110% secondary containment | Single wall (none) |
| Environmental Insurance | $2M cleanup policy (10 years) | None (homeowner liable) |
| Internal Rust | Impossible (HDPE inner tank) | High risk from condensation |
| Weight | Up to 50% lighter | Heavy, hard to maneuver |
| Leak Detection | Built-in optical alarm | None until visible damage |
| Lifespan | 30+ years | 15 to 20 years average |
| Groundwater Risk | Near zero | Significant (single-wall failure) |
Protecting Long Island's Drinking Water
Long Island relies entirely on a sole-source aquifer for its drinking water. Unlike most of the country, there is no backup water supply. Every drop that comes out of your tap started as rainwater that filtered through the ground beneath your property.
A single leak from an old steel oil tank can contaminate the soil and groundwater beneath your home, leading to cleanup costs that regularly exceed $100,000 and can reach $500,000 or more. Nassau and Suffolk County officials strongly recommend double-wall tanks because they eliminate this risk entirely.
Every Roth tank installed by Domino's comes with $2 million in environmental insurance coverage that protects you for 10 full years. If the unthinkable happens, you are covered. With a single-wall steel tank, the entire financial burden falls on the homeowner.

-- Michael R."They handled the permit, removed the old tank, installed the new Roth, and transferred the oil. We did not have to do a thing."
