PVI Water Heater – Durawatt

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.
