Roth 2335101861 Double Wall 165 Gallon Vertical Oil Tank

Product Description

The Roth 2335101861 is a double wall 165 gallon vertical oil storage tank designed for residential and light commercial heating oil applications. This tank measures 28 inches wide by 29 inches long by 61 inches high, making it a compact vertical solution for tight mechanical rooms, basements, and utility spaces. HVAC installers and plumbing contractors rely on tanks like this one for reliable fuel oil storage that meets modern safety and environmental standards.

The double wall construction is the defining feature of the Roth 2335101861. The primary internal tank is made from seamless blow molded polyethylene. Polyethylene resists corrosion and does not rust, which extends the service life of the tank and reduces the risk of fuel contamination. The secondary outer tank is constructed from 19 gauge galvanized steel. This two in one design means the inner tank is fully contained within the outer tank, providing a built in secondary containment layer. If the inner tank ever develops a leak, the outer steel shell captures the fuel before it can reach the floor or surrounding environment. This design eliminates the need for a separate containment pan or berm in most installations.

All seam edges on the steel outer tank have sealant applied before being rolled to create leak proof seams. Both the inner and outer tanks are pressure tested during the assembly process, confirming their integrity before they leave the factory. The tank is UL-2258 listed, meeting the Underwriters Laboratories standard for double wall above ground heating oil tanks. This listing is commonly required by local codes and fire marshals for residential oil tank installations.

The top of the tank features four 2 inch tappings. These connection points allow installers to attach a fill line, vent line, supply line, and gauge or alarm as needed. Large grip handles are located on each end of the tank to assist with positioning and moving during installation. The tank ships with a detached saddle base that must be used at the time of installation to keep the vertical tank stable and properly elevated off the floor. Each tank package includes the base, two 3 inch plastic adapters, and two metal adapters. For outdoor installations, an optional rain cover is available but must be purchased separately.
