Izinto zekhoyili evulekile ziwuhlobo olusebenza kahle kakhulu lwento yokushisa kagesi kanti futhi zisebenza kahle kakhulu ekusetshenzisweni okuningi kokushisa. Ezisetshenziswa kakhulu embonini yokushisa yemibhobho, izinto zekhoyili evulekile zinezisekethe ezivulekile ezifudumeza umoya ngqo kusuka kumakhoyili aqinile aqinile. Lezi zinto zokushisa zezimboni zinezikhathi zokushisa ezisheshayo ezithuthukisa ukusebenza kahle futhi zenzelwe ukugcinwa okuphansi kanye nezingxenye ezishibhe kalula.

Izinto zokushisa zekhoyili evulekile zivame ukwenziwa ukuze kufudunyezwe inqubo yepayipi, umoya ophoqelelwe kanye nama-oven kanye nezicelo zokushisa amapayipi. Izifudumezi zekhoyili evulekile zisetshenziswa ekufudumaleni kwethangi kanye nephayiphi kanye/noma epayipini lensimbi. Kudingeka isikhala esincane esingu-1/8'' phakathi kwe-ceramic nodonga lwangaphakathi lwethubhu. Ukufaka isici sekhoyili evulekile kuzohlinzeka ngokusatshalaliswa kokushisa okuhle kakhulu nokulinganayo endaweni enkulu.

Izinto ze-open coil heater ziyisisombululo sokushisa sezimboni esingaqondile sokunciphisa izidingo zobuningi be-watt noma ukugeleza kokushisa endaweni engaphezulu yepayipi exhunywe engxenyeni efudumele futhi kuvimbele izinto ezizwela ukushisa ukuthi zingabi noma ziqhekeke.
