Izintambo eziqondile ngokuvamile zisetshenziswa opharetha benethiwekhi yokusabalalisa abaxhumanisa amanethiwekhi kagesi nemibhoshongo nekhaya lomuntu noma ibhizinisi.Efanele ukungcwatshwa okuqondile, aphinde asetshenziswe emibhoshongweni emibhoshongo ephakeme kakhulu nasezinhlelweni zokukhanyisa emigwaqweni.
Okokuxhumana kunethiwekhi ephezulu, efakwe phakathi kweinethiwekhi yesibili yokusabalalisa phezulukumamitha wabasebenzisi ngamunye.Isetshenziselwa ikakhulukazi ukuvimbela ukwebiwa kwamandla.Izinga Lokushisa Lokusebenza: 75°C noma 90°C.
