Electric Hot Water Boiler

From 30KW to 4,320KW and up to 415 PSIG Design Pressure

The Vapor Power electric hot water and steam boilers are designed to provide fast, efficient, and economical hot water or steam for heating and process through the use of electric resistance elements. The boiler controls automatically energize/de-energize steps of elements to maintain the desired water temperature or steam pressure. All boilers utilize ASME pressure vessels and all electrical components are UL listed and are wired in accordance with the current National Electrical Code requirements.

HEATING ELEMENTS: The Incoloy-sheathed immersion resistance-type heating elements used for boilers in this bulletin have moderate watt densities (70wpsi) to ensure long life. The elements are constructed of high grade resistance wire (80% nickel, 20% chromium) surrounded by compacted magnesium oxide in Incoloy 800 (SS 332) sheathing.

Electric boiler hairpin elements have a unique fold-back design with repressed bends. This configuration affords ideal spacing between sections of individual elements and between adjacent elements thus allowing maximum water flow and heat dissipation. Special compression fittings permit elements to be individually replaced with standard tools.
