Overview


Model BW ASME Packaged Indirect Fired Water Heater

The Model BW is a fully packaged indirect fired water heater which utilizes boiler water or high temperature hot water (HTHW) as the energy source for heating potable water. The entire package is designed to be a reliable and long lasting source for hot water. Each component is carefully selected to ensure high performance in even the most demanding application. Whether you are heating potable water in a commercial building or process water in an industrial application, you can select a Hubbell BW model to do the job. When you specify and install a Hubbell indirect water heater, you will be provided with a quality product that is a long lasting and trouble-free source for hot water.

  • Only high grade materials used in construction to ensure long operating life
  • Hydrastone cement lining provides superior protection and tank longevity
  • Heavy duty construction withstands demanding commercial/industrial use
Packaged System
  • Factory selected and sized boiler water control valve simplifies installation and ensures reliable operation
Versatile
  • Full range of styles, sizes, and optional features to meet your exact heating needs

Boiler Water Control Valve Selection

Hubbell Model BW indirect fired water heaters are factory furnished with a boiler water control system to regulate the flow of boiler water through the heating coil. The following is an overview of the various Boiler Water Control Systems available.

This is the most commonly selected method for regulating the boiler water. A 3-Way control valve allows only the required amount of boiler water into the heating coil in order to satisfy the demand. Any excess boiler water is diverted back to the boiler water circulating loop. This valve type can be selected as either electric or pneumatic powered.

This control system will allow only the required amount of boiler water into the coil to satisfy the demand. As the water temperature in the tank approaches the set point, the flow of boiler water to the coil is decreased. This control valve does not divert unused boiler water back to the circulation loop. This valve can be selected as either electric or pneumatic powered. For proper valve sizing, the boiler water pressure must be know to ensure that the valve can properly close off during operation.

This control system operates via a thermostat which opens or closes the control circuit to an independent boiler water circulation pump. The thermostat is wired into the control circuit of the circulation pump and will close the control circuit when heat is required (thereby turning the pump on) and will open the control circuit when the water temperature in the storage vessel reaches the thermostat set point, thereby turning the pump off.


Model BW Storage Type Standard Equipment
Vessel Construction
  • All welded carbon steel pressure vessel designed and built in strict accordance with the ASME Code Section VIII and stamped, certified, and registered with the National Board of Boiler and Pressure Vessel Inspectors

Operating Controls
  • Boiler water control valve can be factory selected and sized, but shipped loose for in the field installation by others
  • Single solenoid safety system closes the boiler water supply to the heating coil should the water temperature in the tank reach the hi-limit set point. Requires 120 volt 5 amp electrical service
  • A double solenoid safety system dumps over heated water in the storage tank to drain in addition to closing the boiler water supply to the heating coil. Requires 120 volt 5 amp electrical service. Note: Not recommended for storage tank applications greater than 200 gallons.
  • Intra-tank circulation pump package continuously circulates water within the tank in order to reduce stratification
  • Dial water thermometer and pressure gauge factory installed in the tank
  • Anticipator control system forces incoming cold water over the control valve sensing bulb in order to begin heating water immediately
  • Factory wrapped and baffled heating coil with integral pump package
  • Dual energy package provides operational flexibility by utilizing an electric back-up heating element.
