Durawatt

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.
