DURAWATT® ELECTRIC - a SUPERTANK® Water Heater


Durawatt Electric Water Heater

Available with AquaPLEX Duplex Alloy

PVI holds a UL panel shop stamp of approval. The workmanship of our electrical panels is unmatched in the industry.

DURAWATT is a heavy-duty, medium to large capacity electric water heater. Design avoids large, high-kilowatt tube bundles that can be difficult to maintain. Instead, individual heating elements rated at 9 or 18kW are combined for higher recovery requirements. Standard heating elements are Incoloy sheathed with bronze mounting flanges (optional sheathing material available). Proportional sequencing of heating elements is optional.

Available with electronic operating controls that are Modbus connectable to a building automation system.
