Rheem-Ruud Point-Of-Use Electric Commercial Water Heaters
Brand: Rheem-Ruud
Overview
Rheem-Ruud point-of-use electric commercial water heaters are designed to provide hot water at the consumption point, eliminating costly temperature loss in long piping runs. They are well-suited for a wide variety of applications, being small enough for installation in limited spaces under counters, mop sinks, cabinets, or any remote area where modest quantities of hot water are required. They are ideally suited for applications in retail stores, public restrooms, office washrooms, kitchens, and mop or bar sinks.
Available in sizes ranging from 2-1/2 to 30 Gallon Tank-Type Models, with wattages from 1440 Watts thru 6000 Watts.
The units are designed for various voltage inputs: 120V, 208V, 240V, 277V, and 480V.
Certifications include design certification by Underwriters Laboratories (UL) to meet UL standard 174 as electric storage tank water heaters. They are also North Carolina Code compliant and certified for a 150 PSI maximum working pressure.
Construction Features
Long life tank design
Proprietary steel formulation with a unique coat of high-temperature porcelain enamel to maximize corrosion resistance, resulting in a superior tank design. A patented R-Tech anode rod provides advanced technology, equalizing aggressive water action while prolonging the effective life of the anode rod and, in turn, the life of the tank.
Long life heating elements
Patented resistor elements designed with a specially treated, double layer of magnesium oxide and copper to resist corrosion.
Efficient design
Rigid polyurethane foam insulation provides superior insulating qualities, resulting in reduced operating costs.
Optional wall mounting kit
Provides an easy way to mount the unit off the floor, out of the way for more usable floor space in a small area. Each kit is designed for walls with 16" stud centers. All necessary parts are included. (Note: The 2-1/2 gallon model comes standard with a wall mounting kit.)
Automatic temperature control
A surface-mounted thermostat automatically cycles on and off to maintain the water temperature at a desired preset level.
Temperature limiting control
Automatically and safely cuts off the power in the unlikely event that the water temperature exceeds 190°F (87.8°C).
Temperature and pressure relief valve
AGA/ASME rated and factory installed.
Certifications and Ratings
Efficiency
Models meet or exceed thermal efficiency and standby loss requirements of current ASHRAE standards (part of the Federally mandated Energy Policy Act (EPact)). Also exceeds energy efficiency codes of all states, including California Energy Commission (CEC).
Safety and construction
Products are design certified by Underwriters Laboratories (UL) to meet UL standard 174 as electric storage tank water heaters. All models are North Carolina Code compliant.
