• EHWB model boilers are designed and manufactured according to the system
which transfers the heat via submerged electrical resistance heaters to the water.

• EHWB boilers are cylindrical vessels with proper resistance connection flanged nozzles. For small capacities vertical cylindrical vessel design is preferred, for high capacities horizontal design is used.

• The electrical resistance heat load is selected as less than 10 W/cm2.

• Multiple flanged connected resistance heaters are selected to be able to continue
the boiler operation in case of a heater element failure.
