Hita yekunyudza inopisa mvura mukati mayo.Pano, pane chinhu chinopisa chakanyudzwa mumvura, uye simba remagetsi rakasimba rinopfuura naro rinoita kuti ripise mvura inosangana nayo.
Chidzitiro chekunyudza iheater yemvura yemagetsi inogara mukati mesilinda yemvura inopisa.Inoita zvishoma seketero, ichishandisa hita yemagetsi yekudzivirira (inotaridzika sesimbi yesimbi kana coil) kupisa mvura yakapoteredza.
WNH's immersion heaters yakagadzirirwa kunyanya kunyudzwa mumvura, mafuta, zvinonyungudutsa uye zvinogadzirisa zvinogadzirisa, zvinhu zvakanyungudutswa pamwe nemhepo nemagasi.Nekuunza kupisa kwese mukati memvura kana maitiro, mahita aya anokwana zana kubva muzana anoshanda nesimba.Aya maheater akasiyana-siyana anogona zvakare kuumbwa uye kuumbwa kuita akasiyana geometries ekudziya anopenya uye kubata pamusoro pekudziya kwekushandisa.
