Izinto zekhoyili evulekileyo zezona ntlobo zisebenza kakuhle kakhulu zesixhobo sokufudumeza ngombane ngelixa zikwayezona zifanelekileyo ngokwezoqoqosho kwiintlobo ezininzi zezicelo zokufudumeza. Zisetyenziswa kakhulu kwishishini lokufudumeza imibhobho, izinto zekhoyili evulekileyo zineesekethe ezivulekileyo ezifudumeza umoya ngokuthe ngqo kwiikhoyili ezixhathisiweyo. Ezi zinto zokufudumeza zemizi-mveliso zinamaxesha okufudumala akhawulezayo aphucula ukusebenza kakuhle kwaye zenzelwe ukugcinwa okuncinci kunye neendawo zokutshintsha ezingabizi kakhulu.

Izinto zokufudumeza ezivulekileyo zenzelwe ukufudumeza ngenkqubo yemibhobho, umoya ophoqelelweyo kunye nee-oveni kunye nokusetyenziswa kokufudumeza ngemibhobho. Izifudumezi ze-coil ezivulekileyo zisetyenziswa ekufudumezeni itanki kunye nemibhobho kunye/okanye kwiityhubhu zesinyithi. Kufuneka ubuncinci be-1/8'' phakathi kwe-ceramic kunye nodonga lwangaphakathi lwetyhubhu. Ukufakela into ye-coil evulekileyo kuya kubonelela ngokusasazwa kobushushu okugqwesileyo nokulinganayo kwindawo enkulu.

Izinto ze-open coil heater zisisombululo sokufudumeza esingathanga ngqo kwimizi-mveliso ukunciphisa iimfuno zoxinano lwe-watt okanye ukufudumeza kobushushu kumphezulu wombhobho oqhagamshelwe kwicandelo elishushu kwaye zithintele ukuba izinto ezibuthathaka kubushushu zingabi shushu okanye zonakale.
