How to Choose the Right Roth Tank Size
Picking the right tank comes down to three things: your home's heating demand, the space you have available, and how often you want oil delivered.
Home Size and Heating Demand
A 1,000 sq ft ranch uses far less oil than a 3,000 sq ft colonial. Homes under 1,000 sq ft can often get by with a 110-gallon. Most Long Island homes between 1,200 and 1,700 sq ft are well served by the 275-gallon. Larger homes or those with multiple heating zones should consider the 400-gallon for fewer deliveries and better bulk pricing.
Available Space
Ceiling height is the most common limiting factor. The 110-gallon needs just 48 inches of clearance. The standard 275-gallon needs 66 inches, but the low-height model fits in 58 inches. The 400-gallon requires 76 inches. Floor space matters too, especially if you are placing the tank in a utility closet, crawl space, or against a wall near your burner.
Delivery Frequency
A larger tank means fewer oil deliveries per year. With a 275-gallon, most homeowners get delivery every 3 to 4 weeks in winter. The 400-gallon extends that to 5 to 6 weeks, reducing scheduling hassle and letting you take advantage of lower per-gallon pricing on larger fills.
Every Size Gets the Same Protection
No matter which Roth you choose, you get identical construction, warranty, and insurance.
Double-Wall Construction
Polyethylene inner tank that will never rust or corrode, surrounded by a 19-gauge galvanized steel outer shell. If the inner tank ever leaks, the outer shell contains it. Every size uses the same materials and build quality.
30-Year Warranty
Roth's 30-year limited manufacturer warranty covers defects in materials and workmanship. It applies equally to the 110, 275, and 400-gallon models. No other residential oil tank comes close to this level of coverage.
$2M Environmental Insurance
Every Roth tank includes 10 years of environmental insurance with up to $2 million in cleanup coverage and $2 million in property damage coverage per occurrence. This protects your home, your property, and Long Island's groundwater.
What Every Roth Installation Includes
Regardless of which size you choose, the price covers a complete, turnkey installation.
- Brand-new Roth double-wall tank in your chosen size
- Removal and disposal of your old steel tank
- New copper supply and return lines
- New shut-off valves and oil filter

Roth Tank Size FAQ
What sizes do Roth double-wall oil tanks come in?
Roth manufactures three residential oil tank sizes: 110-gallon (DWT 400L), 275-gallon (DWT 1000L standard and DWT 1000LH low-height), and 400-gallon (DWT 1500L). All three use identical double-wall construction with a polyethylene inner tank and galvanized steel outer shell. Domino's installs all three sizes across Long Island.
Which Roth tank size is most popular on Long Island?
The 275-gallon is by far the most popular choice on Long Island. It fits most 3-bedroom homes between 1,200 and 1,700 square feet and provides several weeks of heating oil during winter. It is a direct replacement for the standard 275-gallon steel tank that most Long Island homes already have.
How much does a Roth oil tank cost installed on Long Island?
Roth oil tank installation prices on Long Island: 110-gallon costs $2,690 to $3,290, 275-gallon costs $2,990 to $3,690, and 400-gallon costs $4,500 to $6,300. All prices include the tank, old tank removal, new copper piping, Tiger Loop, oil transfer, system testing, 30-year warranty, and $2 million environmental insurance. Call (631) 881-4772 for a free in-home estimate.
Do all Roth tank sizes come with the same warranty?
Yes. Every Roth double-wall tank comes with the same 30-year limited manufacturer warranty and 10 years of environmental insurance with up to $2 million in cleanup coverage and $2 million in property damage coverage per occurrence, regardless of tank size.
How do I know which Roth tank size is right for my home?
The right size depends on your home's square footage, heating demand, and available space. Homes under 1,000 sq ft or supplemental systems typically use a 110-gallon. Most 3-bedroom Long Island homes use a 275-gallon. Homes over 2,500 sq ft or multi-zone systems benefit from the 400-gallon. Call (631) 881-4772 for a free in-home assessment where we measure your space and recommend the best fit.
Can I upgrade to a larger Roth tank than what I currently have?
Yes. Many homeowners upgrade from a 275-gallon to a 400-gallon for fewer oil deliveries and better bulk pricing. During your free estimate, we measure your space and confirm that the larger tank will fit. If ceiling height or access is tight, we will recommend the best option for your layout.
What Our Customers Say
"Domino's helped us pick the right size for our home. We went with the 275-gallon low-height model because our ceiling is only 6 feet. Perfect fit."
-- Lisa M."Upgraded from a 275 to a 400-gallon Roth. Now we only get oil delivered every 5 weeks instead of every 3. Wish we had done it sooner."
-- Tom R."We have a small cottage and the 110-gallon was exactly what we needed. Same warranty as the bigger tanks. Domino's was in and out in a few hours."
