I-heater kagesi ye-Glycol iwuhlobo lwemishini yokonga amandla eshisa kuqala impahla, efakwa ngaphambi kwemishini yezinto ezibonakalayo ukuze ibone ukushisa okuqondile kwento, ukuze ikwazi ukushiswa emjikelezweni wokushisa okuphezulu, futhi ekugcineni ifinyelele inhloso yokonga amandla. Isetshenziswa kakhulu ekushiseni kwangaphambili kwamafutha asindayo, i-asphalt, uwoyela ohlanzekile namanye amafutha kaphethiloli. I-heater yamapayipi yakhiwe izingxenye ezimbili: umzimba kanye nesistimu yokulawula. Isici sokushisa senziwe ngepayipi lensimbi engagqwali njengomkhono wokuvikela, i-high-temperature resistance alloy wire, i-crystalline magnesium oxide powder, eyakhiwe inqubo yokucindezela. Ingxenye yokulawula yakhiwe isekethe yedijithali ethuthukisiwe, i-trigger yesekethe ehlanganisiwe, i-high reverse voltage thyristor kanye nezinye izikali zokushisa ezilungisekayo kanye nesistimu yokushisa engaguquki ukuze kuqinisekiswe ukusebenza okuvamile kwe-heater kagesi.
