Umgaqo osebenzayo wembiza yebhatyi kukusebenzisa ukupheka koxinzelelo lwangasemva. Ngokulula nje, kukusebenzisa umoya oxinanisiweyo ukunyusa uxinzelelo embizeni ukuthintela iitoti ukuba zingaphumi kwaye zixhume. Ngoko ke, kwinkqubo yokuvala inzala kunye nokufudumeza, musa ukubeka umoya oxinzelelweyo, kodwa kufuneka ube kwindawo yokugcina ubushushu emva kokufikelela kwiqondo lokushisa. Emva kokuba inzala igqityiwe, xa ubushushu buhla kwaye bupholile, ukunikezelwa kwe-steam kumisiwe, kwaye amanzi okupholisa axinzelelwe kumbhobho wokutshiza amanzi. Njengoko iqondo lobushushu embizeni lihla, umphunga uyajiya, kwaye noxinzelelo lwembiza lubuyekezwe luxinzelelo lomoya oxinanisiweyo. Kwinkqubo yokuvala inzala, ingqalelo kufuneka ihlawulwe kwindlela yokuqala yokukhupha, kwaye emva koko i-steam ikhutshwe ukuze ijikeleze i-steam. Isenokuthi ithotywe rhoqo kwi-15 ukuya kwimizuzu engama-20 ukukhuthaza ukutshintshiselana kobushushu.
