Description

Raises incoming hot water to the 180°F final rinse a high-temp dishmachine needs, from a 16-gallon tank built for busy dish rooms.

Hatco S-15 Imperial electric booster water heater on legs, front three-quarter view

The Hatco S-15 is a 15 kW Imperial electric booster water heater. It stores 16 gallons in a Castone-lined tank and recovers 151 gallons per hour at a 40°F temperature rise, or 86 gallons per hour at a 70°F rise. Service access is from the front, so it can be installed close to other equipment, and the thermostat can be lowered to a 140°F setting for low-temp dishmachines. Choose 208V 1-phase, 208V 3-phase, 240V 1-phase, 240V 3-phase or 480V 3-phase power when you order.

Will it fit · Will it hook up

Outside size
23.53" W x 22.75" D x 31.03" H on the standard 6" legs; add 5" to the width for the temperature/pressure relief valve
Power
208V 1-phase 72 A, 90 A breaker; 208V 3-phase 41.7 A, 60 A breaker; 240V 1-phase 62.5 A, 90 A breaker; 240V 3-phase 36.1 A, 50 A breaker; 480V 3-phase 18.1 A, 30 A breaker. Hard wired: the electrician supplies the breaker or fused disconnect
Water
3/4" NPT inlet and outlet; incoming water over 3.0 grains per gallon hardness must be softened
Location
Indoors, 70°F room or warmer, as close to the dishmachine as possible; recirculate if the run is over 5 ft. (NSF)
Clearance
Front access to the controls; Hatco recommends at least 2" at the sides

Have the electrician confirm the voltage, phase and circuit before the heater arrives: Hatco electric boosters are hard wired with no cord or plug.

151 GPH recovery

At 15 kW the S-15 heats 151 gallons per hour through a 40°F rise and 86 gallons per hour through a 70°F rise, for a 180°F final rinse.

Castone-lined tank

The 16-gallon tank has a Castone lining and fiberglass insulation to cut heat loss. Hatco backs the tank with a 10-year limited warranty.

Low-water cut-off

A low-water cut-off keeps the elements off when the tank is low, and a high-temperature limit switch adds a second safety.

Front service access

Controls and service area open from the front, and a built-in heat trap helps hold heat in the tank.

Factory plumbed and wired

It arrives pre-plumbed and pre-wired with an immersion thermostat, temperature/pressure relief valve, pressure reducing valve and two temperature/pressure gauges.

Delivery and setup

  • Inspect the carton for damage before you sign, and note any damage on the delivery receipt. Approximate shipping weight is 200 lb.
  • Installation must be done by qualified installers to local electrical and plumbing codes. Installation by unqualified personnel voids the Hatco warranty.
  • Fill the tank with water before you turn on power: the elements burn out if they run dry.
  • Set the pressure reducing valve to 20 psi flow pressure, and do not fit a check valve or anti-siphon valve in the supply line to the booster.
  • Pipe the temperature/pressure relief valve discharge to a safe place of disposal, per local code.

Questions buyers ask

Is it big enough for my dishmachine?

Size it by the gallons per hour your dishmachine rinse uses and your incoming water temperature. The S-15 recovers 151 GPH at a 40°F rise (140°F in, 180°F out) and 86 GPH at a 70°F rise (110°F in). If your machine uses more, step up in kW.

What electrical service does it need?

Pick the voltage and phase you have on site: 208V 1-phase draws 72 A on a 90 A breaker; 208V 3-phase draws 41.7 A on a 60 A breaker; 240V 1-phase draws 62.5 A on a 90 A breaker; 240V 3-phase draws 36.1 A on a 50 A breaker; 480V 3-phase draws 18.1 A on a 30 A breaker. It is hard wired by a licensed electrician.

Can it be converted to another voltage or phase later?

No. Only Hatco's 6, 7 and 9 kW models can be field converted, so order the voltage and phase you have.

Does my water need treatment?

Yes, if it is hard. Water over 3.0 grains of hardness per gallon must be treated and softened before it reaches the booster. Failure from liming or sediment is not covered by the warranty.

Will it work with a low-temp dishmachine?

Yes. Hatco notes the Imperial thermostats can be lowered to a 140°F setting for low-temp dishmachines.

What warranty does it have?

Hatco covers the booster tank for 1 year parts and labor plus 9 more years parts only. Other parts carry Hatco's standard 18-month limited warranty. Register the unit with Hatco within 90 days of factory shipment to qualify for added coverage.
