HWS

The PRECISION Model HWS (Hot Water Storage) Heaters are Commercial Volume Storage Water Heaters designed for industrial, commercial and institutional users who require quantities of service water and preset temperatures.

When the job calls for lots of hot water – when it is called for quickly – when a continuous supply that will not quit at a crucial moment is needed – when downtime or failure will cause you a problem – IT IS TIME TO THINK PRECISION.

We offer a wide range of storage and recovery capacities to meet you job requirements.

For over 50 years, PRECISION has been supplying hot water to apartments, dormitories, nursing homes, hospitals, motels, schools, universities, restaurants, health care facilities, office buildings, and various kinds of industrial and commercial applications.

These complete Factory-packaged Electric Storage Water Heaters are available in both VERTICAL and HORIZONTAL configurations, and are ASME constructed and National Board Registered for design pressures of your choice of 125 psi or 150 psi. They are constructed under ASME Code Section IV and stamped HLW. Storage capacities are from 125 gallons to 5500 gallons, and recoveries from 62 to 1968 gallons per hour are cataloged with larger sizes available at request to the Factory. Input capacities from 10 kW to 480 kW are cataloged using PRECISION Incoloy-sheathed individually flanged elements in 10, 15, 18 and 20 kW ratings.

Complete Factory package with insulation and 16 gauge enameled jacket, assembled and tested, ready for electrical and water service connections.
Provides energy-efficient water heating where electricity is virtually 100% efficient; and where Factory insulation and steel jacket reduce radiant heat loss to less than 4 watts per square foot of tank surface.
Meets or exceeds the ASHRAE 90.1B-1992 energy standard.
Integrated cabinet design on structural steel base with lifting lugs.
Built-in safety standards, features and controls such as heater UL Labeled, ASME rated Temperature and Pressure Relief Valve to relieve pressure in the event of overheating or excess pressure, two High Temperature Cutouts to limit the tank temperature if it exceeds setpoint, Low Water Cutoff to keep the heater from “dry firing”, Fused Control Circuits to interrupt power in the event of overload condition, and optional safety equipment such as Safety Door Interlock to prevent the opening of control cabinet door(s) while the main power supply is energized.
