Residential Oil Tanks

At CommTank, we choose our products based on years of installing and maintaining heating oil tanks that have a proven record of reliability with manufacturers that stand behind their products. The safe storage and supply of fuel oil to your furnace, boiler, hot water tank or generator is our primary goal.

Residential heating oil tanks are exempt from federal regulation but must comply with local fire ordinances. Each product meets the NFPA (National Fire Protection Association) 30 Flammable and Combustible Liquids Code and Underwriters Laboratory. The oil heat industry has been working to ensure that oil storage tanks are safe. Heating oil tanks installed aboveground must be able to withstand severe heat and not contribute to a house fire. Many products have double-wall containment and leak detectors to provide an extra level of safety and peace of mind.

Granby Tanks

Granby steel tanks have been providing peace of mind to smart homeowners since 1953. Granby tanks have always been tough, but now they are tougher and smarter by being more environmentally friendly. With the Greenshield Ecogard series the tank has extra protection, where it counts; on the bottom. The extra plating covers 100% of the corrosion risk zone at the tank’s base. It has a patented leak detection system that warns you with plenty of time. If ever a leak does occur, the double bottom will prevent an oil spill. This is part of Granby’s commitment to your environment. Granby tanks are UL and ULC certified. If you’re in the market for a standard tank, a polyurethane coated tank or double bottom tank, Granby has a full range of tanks that are built tough, built smart and built to last.

Roth Tanks

Unique double-walled construction

Roth double-wall tanks are the safest and most reliable on the market. The outer tank is made of leak-proof, weld-free galvanized steel and roll seamed with an oil and fire-resistant seal. It can contain at least 110 percent of the capacity of the inner tank for maximum protection. The inner tank is made of blow-molded, high-density, seamless polyethylene that is leak proof and will never corrode. Roth tanks are easier and faster to fill thanks to their unique expansion system, all but eliminating the possibility of spills by home heating oil professionals. And, our compact tanks are available in several different sizes, providing more flexibility for placement in any home.

Roth oil tanks are rust resistant inside and out

Built with safety and the environment in mind

Roth oil tanks exceed the industry standard safety regulations. They are rust resistant inside and out and are designed to prevent spills, leaks and fires caused by defective pipes, couplings or fittings located underneath the tank. In fact, it is the only tank on the market with no fittings below the oil line. Each tank undergoes thorough testing, including ultra-sound and pressure testing, to ensure optimal thickness and sealing.
