Chowumitsira chimagwira ntchito potulutsa nthunzi ndi kuchotsa chinyezi kuchokera kuzinthu kudzera mu kutentha ndi mpweya wabwino, motero zimakwaniritsa kuyanika. Makamaka, chowumitsira nthawi zambiri chimakhala ndi makina otenthetsera, mpweya wabwino, makina otumizira zinthu, ndi makina owongolera. Dongosolo lotenthetsera limapereka gwero la kutentha, mpweya wabwino umagawira mpweya wotentha mofanana pamtunda wa zinthu, makina otumizira zinthu amaonetsetsa kuti kutentha kwa yunifolomu panthawi yowumitsa, ndipo dongosolo lolamulira limayang'anira kutentha ndi chinyezi kuti zitsimikizire kuyanika.
