About Granby Oil Tanks

Domino is an authorized Granby dealer, and we install, replace and service Granby oil tanks across Long Island. Since we also deliver your heating oil, we size the tank around how you actually use oil, not just the size of the old one.

Granby Industries was founded in 1954 and describes itself as a North American maker of heating, cooling and storage equipment. Its residential tank line covers single-wall steel, double-bottom steel, steel-and-plastic double wall and fiberglass, so there's a Granby option for a basement, a garage or the side of the house.

Granby works closely with ECR International, the heating company behind Utica, Dunkirk and Airco. The Granby name also appears on oil furnaces: Granby Furnaces, Inc. issues the warranty on Airco and Olsen oil furnaces.

Granby Oil Tanks for Long Island Homes

Most Long Island oil tanks are 275-gallon steel tanks in a basement, and the EcoGard drops into that same footprint. Its double bottom is the point: if the inner floor ever leaks, the oil is held in the space below and shows on a visual monitor, so you find out before oil reaches the slab.

The Standard is the lower-cost choice: a single-wall steel tank from 120 to 330 gallons, set vertical or horizontal, with a 3-year warranty. It suits a tight budget or a short stay in the house.

For an outdoor tank near the water, where salt air and wet winters are hard on steel, ask us about a Roth double-wall tank, which Roth lists for outdoor use with its cover.

Long Island Oil Tank Rules for Granby Tanks

In Suffolk County, Article 12 of the Sanitary Code exempts residential heating oil tanks under 1,100 gallons that are indoors or aboveground outdoors from the Permit to Construct, and sites with only heating oil under 1,100 gallons are exempt from registration, according to the county Health Department.

In Nassau County, the Department of Health handles closures of heating oil tanks of 1,100 gallons or less. A tank removal has to be scheduled at least 7 days ahead and needs a county inspection, and the county says aboveground tanks should be removed and disposed of whenever they're replaced. Nassau points new tank installs to Article XI of its Public Health Ordinance, which requires structural strength and corrosion resistance.

Warranty

Granby Oil Tank Warranty

Granby says its tanks carry warranties of 3 to 30 years, depending on the model and the install date. Coverage usually applies only at the original install location, and Granby says moving the tank may void it.

The EcoGard's 25-year warranty applies to tanks installed after June 15, 2011; older EcoGards had 15 years. We register the warranty for you and leave the certificate with you after the install.

On top of the manufacturer's coverage, Domino backs every installation with a 1-year labor warranty.

Granby EcoGard vs Roth Double-Wall Oil Tanks

These are the two upgrades homeowners ask us about most. The Granby EcoGard is a 12-gauge steel tank with a second steel bottom. A Roth tank has a one-piece blow-molded polyethylene inner tank inside a full galvanized steel outer tank that holds 110% of the inner tank.

Granby's EcoGard has a 25-year warranty. Roth's double-wall tank lists 30 years with 10 years of insurance and a cleanup policy of up to 2 million dollars, when installed by a Roth Certified Installer. The EcoGard fits a standard 275 footprint; the Roth is lighter and narrower. We're an authorized dealer for both, so we can show you each one for your space.

Good to Know

Granby Oil Tank Service and Common Problems

We'll check your tank during any fill or service visit if you ask. Signs it needs attention:

  • Leak monitor showing oil: the inner bottom has failed and the tank needs replacing.
  • Damp spots or weeping at the bottom of an old single-wall tank: corrosion from water and sludge inside.
  • Vent whistle silent during delivery: a failed whistle or blocked vent, which risks an overfill.
  • Gauge stuck or unreadable: a broken float gauge that needs replacing.
  • Rust on outdoor legs or seams: coating failure from weather and salt air.

  2. We schedule any county notice the job needs.
  3. We pump the remaining oil, disconnect the old tank and take it away.

FAQ

Granby Oil Tank FAQs

Common questions about this oil tank brand on Long Island.

1Is Domino an authorized Granby dealer?

Yes. Domino is an authorized Granby dealer and installs Granby residential oil tanks across Long Island.

2Which Granby tank should I choose?

The EcoGard, if you want leak protection: its double bottom and visual monitor catch a leak early, and it carries a 25-year warranty. The Standard costs less and carries 3 years.

3Can a Granby tank go outside?

Granby sells an outdoor protection kit as an accessory, but its site doesn't list an outdoor rating for the EcoGard. For an outdoor install, ask us about a Roth tank, which Roth lists for outdoor use with its cover.

4Do I need a permit to replace my oil tank in Suffolk?

Usually not a Permit to Construct. Suffolk exempts residential heating oil tanks under 1,100 gallons that are indoors or aboveground outdoors.

5How long does a Granby tank swap take?

Most basement swaps take part of a day, including pumping out, removal, setting the new tank and moving the oil back.
