The Rheem 120-Gallon Commercial Hot Water Storage Tank is a robust vertical tank engineered for high-demand applications requiring large volumes of hot water in short bursts. Built with Rheem-Ruud commercial-grade durability, this tank pairs seamlessly with Rheem-Ruud water heaters to deliver reliable performance in restaurants, hotels, laundromats, and other commercial settings where consistent hot water supply is critical.
Constructed from a proprietary steel formulation with two coats of high-temperature porcelain enamel, the tank resists corrosion and extends service life. It includes two heavy-duty magnesium anode rods for added protection, ensuring long-term efficiency. The tank’s compact design allows it to pass through a 30-inch opening, simplifying installation in tight spaces. Standard connections include a 2-inch NPT circulating line and hot water outlet, with additional openings for the temperature and pressure (T&P) relief valve and temperature control. Note that the T&P valve must be purchased separately, as it is not included.
