'Marakeng oa hona joale oa liphaephe tsa tšepe tse se nang sekoli, litlhoko tsa bareki li ntse li eketseha ka potlako, haholo-holo bakeng sa liodara tse nang le palo e nyane ea odara. Mokhoa oa ho fihlela litlhoko tsena tsa bareki e se e le ntho ea bohlokoa ka ho fetisisa ho rona. Ha re tobane le boemo bona, re buisana ka mafolofolo le lifeme tse kholo 'me re loanela ho kopanya mehloli ea lisebelisoa le litlhaloso tse fapaneng ho netefatsa hore bareki ba ka fumana lihlahisoa tse hlokahalang ka nako e khuts'oane.

Taba ea pele, re tla utloisisa litlhoko tse ikhethileng tsa bareki ka botlalo, ho kenyeletsoa le tlhahisoleseling e kang thepa, litlhaloso le bongata ba phaephe ea tšepe e hlokahalang. Kamora ho tseba tlhahisoleseling ena, re tla ikopanya le balekane ba rona ba ketane ea phepelo kapele ho batla lethathamo la lintho tse fumanehang ho netefatsa hore re ka fana ka lihlahisoa tse fihlelang litlhoko tsa bareki. Ka nako e ts'oanang, re tla boela re fetole leano la rona la theko ka mokhoa o feto-fetohang ho fihlela litlhoko tse fapaneng tsa bareki, ho kopanya liodara tse nyane tsa sehlopha, le ho fihlela litlhoko tsa theko ea bareki.

Ho phaella moo, e le ho ntlafatsa bokgoni ba ho fana ka thepa, re tla boela re matlafatse tshebedisano-mmoho ya ka hare ho netefatsa tshebetso e sebetsang hantle tlhahisong le tsamaisong ya thepa. Re tseba hantle hore ho fana ka thepa ka nako ha se feela boitlamo ba ho tshepa bareki, empa hape ke motheo wa bohlokwa wa ho boloka dikamano tse ntle tsa kgwebo. Ka hona, re tla tswela pele ho boloka ho tenyetseha le bokgoni, mme re ikitlaelletse ho fa bareki ditharollo tse ntle ka ho fetisisa e le hore ba ka fumana tshehetso le ditshebeletso ka nako maemong a tshohanyetso. Ka boiteko bo jwalo, re dumela hore re ka hlahella tlholisanong e matla ya mmaraka mme ra hapa tshepo le tshebedisano-mmoho e eketsehileng ya bareki.

Liphaephe tse kholo tsa tšepe tse se nang mohele tsa Sanonpipe li kenyelletsa liphaephe tsa boiler, liphaephe tsa manyolo, liphaephe tsa oli le liphaephe tsa sebopeho.
