Booster Water Heaters (Electric)

• What is the typical lead time for a Booster Water Heater NOT available in the Quick-Ship program?

  The lead time is generally 3-4 working days from date of order entry. Booster Water Heaters in Quick-Ship are sent out the same day when orders are received by 12PM Central Standard Time.

• What is a shock absorber and what is it used for?

  A shock absorber is an accessory item that can be used in any water heater application. It reduces water hammer, or the "banging noise" that results from quick closing solenoid valves on the dishwasher.

• What information needs to be included on an order for a Booster Water Heater?

  Necessary information is the Booster Water Heater’s model number, voltage, phase, quantity, mounting style (for Compact series), jacket material and accessories.

• The dishwasher application chart shows my dishwasher requiring a C-12 or a S-12 electric Booster Water Heater. Why do I want one versus the other?

  The fundamental difference is the S-12 Imperial Electric Booster Water Heater has a 16 gallon (60 liter) tank, and the C-12 Compact Electric Booster Water Heater has a 6 gallon (23 liter) tank. The S model has a larger footprint, which provides easier service ability and will step load the electricity in the higher kW range, which will reduce the operator's demand charges on their electric bill.

• Should anything be specified differently when ordering a Booster Water Heater to be used in a low temperature application?

  The order should specify that the Booster Water Heater is for a low temperature application, and the factory will pre-set the thermostat to 140°F (60°C). There is a low temperature sizing chart in the Hatco Price List or on the website to verify sizing.

• How is a Booster Water Heater to be positioned when installed?

  The Booster Water Heater must be installed in a horizontal position, with the base parallel to the floor and the inlet connection at the lowest point. The Booster Water Heater must be within five (5) linear feet of the dishmachine.

• Can a Booster Water Heater be used as a primary water heater?

  Hatco Booster Water Heaters are not designed to be primary water heaters and do not carry a UL listing for this application.

• With regard to VOLTAGE, are Hatco electric Booster Water Heaters field convertible from 208 volt to 240 volt or 480 volt, and vice versa?

  No. Hatco Booster Water Heaters are manufactured and UL approved specifically for 208, 240 or 480 volts, and are NOT field convertible.

• What standard features are included with Compact and Imperial Electric Booster Water Heaters?

  ¾" piping.

• What size piping is required for Booster Water Heater installations?

  ¾" piping.

• What key information is required when sizing a Booster Water Heater to a dishwasher?

  Essential information is the temperature (degrees Fahrenheit) of the incoming water from the primary water source, temperature rise (incoming water temperature subtracted from 180°F [82°C]), the make and model of the dishwasher the Booster Water Heater will be used with OR the gallons per hour (GPH) (liters per hour [LPH]) required by the dishwasher for the final rinse cycle. The formula to figure kW of the Booster Water Heater needed to sanitize at 180°F (82°C) is: GPH x °F Temp Rise/400 = kW required (LPH x °Celsius Temp Rise/840 = kW required). Sizing charts are available in our price list and on our website.

• What is the warranty on Booster Water Heaters?

  One (1) Year Parts and Labor PLUS Nine (9) Years Parts-Only Warranty.

• What is the tank capacity of the various Booster Water Heaters?

  Compact = 6 gallons (23 liters). Imperial = 16 gallons (60 liters). Mini-Compact = 3.2 gallons (12 liters).

• What is the purpose of a Booster Water Heater?

  The primary function of a Booster Water Heater is to provide 180°F (82°C) of hot water for the final sanitizing rinse in a commercial dishwasher.

• What is the method of shipment for Hatco Booster Water Heaters?

  Because of size and weight, all Booster Water Heaters are shipped via common carrier (truck).

• What is the height range of the optional stainless steel adjustable legs for Strip Heaters (Foodwarmers)?

  6" to 7" (152 to 178 mm).

• What is the function of the Booster Water Heater's low water cut-off?

  The low-water cut-off (LWCO) is a protective device designed to shut off power to the heating elements, thus preventing burnout should the water level decrease in the Booster Water Heater tank. The LWCO is automatically reset when the water level is safe.

• What is step loading?

  Imperial Electric Booster Water Heaters (S series) rated for 24kW or larger have multiple banks of heating elements, with each bank controlled by a separate thermostat. During periods of use, the lowest bank of heating elements turns on first and stays on until its thermostat reaches the setpoint. If additional hot water is needed (during periods of high demand), the next level of heating elements come on and heats. This step loading, or staging of the heating elements, allows for reduced energy costs when compared to units that have all of their elements controlled by one thermostat and are either ON or OFF 100% of the time.

• With regard to PHASE, are Hatco electric Booster Water Heaters field convertible from single- to 3-phase, and vice versa?

  Only 6kW, 7kW or 9kW Booster Water Heaters, 208 volt or 240 volt, are field convertible from single- to 3-phase, or vice versa. All other Booster Water Heaters must be ordered specifically for single-phase or 3-phase, and CANNOT be converted in the field.

• Why order an Imperial Electric Booster Water Heater vs. a Compact Electric Booster Water Heater?

  Step loaded element design can reduce energy costs (above 24kW); a larger tank provides greater capacity and faster recovery; and it is an easier to service larger Booster Water Heater.

• When should gas vs. electric be considered for a Booster Water Heater?

  Use the energy cost worksheet on our website to calculate energy costs per year, and compare to unit cost. Consider installation and maintenance costs. (Contact your local Hatco Representative for assistance.)

• Can I convert an electric Booster Water Heater from single-phase to 3-phase? Or vise versa?

  Only 6, 7 and 9kW electric Booster Water Heaters can be field converted to single-phase (units are shipped 3-phase open delta). A larger branch circuit is required for balanced 3-phase of equal kW – 208 volt and 240 volt only. All other kW models cannot be field converted.

• Are there specific electric Booster Water Heaters that can be wired in single-phase?

  208 volt and 240 volt Booster Water Heaters up to 18kW, and 480 volt in 4kW and 5kW Compact Electric Booster Water Heaters, can be ordered in single phase. While 240 volt in 24kW through 45kW and 208 volt in 24kW through 39kW Booster Water Heaters may be ordered in single phase, consultation with the factory and written confirmation is required, due to high amperage in these types of applications.

• Are there any special provisions for Booster Water Heaters ordered for marine applications?

  Booster Water Heaters are available with 400 series stainless steel body and base (resists rusting from salt air), with stainless steel flanged legs for deck mounting.

• Are there 120 volt plug-in Booster Water Heaters available?

  No. All Hatco Booster Water Heaters come in either 208, 240 or 480 volt and must be hardwired.

• Are slide mount brackets available in lieu of legs on ALL Booster Water Heaters, and is there an extra charge?

  Slide mounting brackets are available only on Compact Electric Booster Water Heaters because of weight and size limitations. Imperial Electric Booster Water Heaters must be mounted on legs. There is no charge for slide mounting brackets when ordered in lieu of legs. When you order slide mounting brackets, you will not receive legs with your Booster Water Heater.
