Ukushisa kwemfucumfucu yezimoto zezimoto zikagesi ezihlanzekile akukwazi ukuhlangabezana nezidingo zokushisa kwasebusika, ngakho-ke ukushisa kwasebusika kuyinkinga ukuthi izimoto zikagesi ezihlanzekile zidinga ukuyixazulula.Ama-heaters amahle okushisa (i-coefficient yokushisa enhle, i-PTC) akhiwe ngezinto zokushisa ze-ceramic ze-PTC namashubhu e-aluminium, anezinzuzo zokumelana nokushisa okuncane nokusebenza kahle kokudlulisa ukushisa, futhi aguqulwa kancane ngesisekelo sezimoto zikaphethiloli.
