Eqinisweni, izinkathazo zalaba basebenzi bamahhotela azinangqondo. Ukulungiswa kabusha kwamahhotela okonga amandla kuyindaba enzima ngempela, kodwa ngeke siyeke ukwenza izinguquko ngenxa nje yokuthi kuyinkinga. Ngoba izindleko zamandla zenza ingxenye enkulu yezindleko zehhotela. Uma ukulahlekelwa kwamandla akhona kuvunyelwe ukuqhubeka, ukulahlekelwa kuzoba kukhulu futhi kukhulu! Isistimu yokushisisa ihhotela “iyagula” futhi kufanele itholwe futhi “yelashwe” ngokushesha ngangokunokwenzeka.
Isibonelo, kwamanye amahhotela manje, ama-boilers akhona anezinkinga ezihlukahlukene ezifana nezinga lokushisa eliphezulu lokukhipha umoya, ukuchithwa kokushisa okukhulu kwendawo, kanye nokusebenza kahle okuphansi. Ngaphezu kwalokho, uhlelo lokushisa aluhambisani nesayensi. Isibonelo, ama-boilers we-steam asetshenziselwa ukushintshanisa ukushisa ukuze anikeze ukushisa kwamanzi ashisayo, futhi amapayipi ashisa kakhulu. Ukukhipha ukushisa isikhathi eside, njll., konke okuzokwenza ukuthi imali yanyanga zonke ihwamuke ohlelweni lokushisa lwehhotela! Ngesikhathi esifanayo, amanye ama-boilers ehhotela adinga ukugunyazwa, adinga ukuhlolwa kwaminyaka yonke, abe nama-boiler rooms azimele, futhi adinga abasebenzi basezithandweni ukuba babambe izitifiketi. Uhlelo luyinkimbinkimbi futhi ludinga ukushintshwa. Ukusebenza kahle kokushisa kuphansi (ngokuvamile u-80%), kukhona ukushiyeka okufana nesikhathi eside sokushisa, ukulahlekelwa ukushisa okukhulu, izindleko eziphezulu zokusebenza, nokukala okulula. Lezi zinkinga zingaxazululwa ngesikhathi nge-Nobeth steam generator.
Lapho senza ukulungisa okonga amandla ehhotela, kufanele "sinikeze umuthi ofanele ecaleni". Okokuqala, thola inkampani yesevisi yokonga amandla echwepheshile noma umkhiqizi ozokhipha isistimu yokushisisa ekhona yehhotela. Uma amaphuzu ephansi kakhulu, kufanele kwenziwe izinhlelo ezifanele zokonga amandla. Ngokuphathelene nomjikelezo wokuvuselela, ukulungiswa kwesistimu yokushisa kungenziwa ngesikhathi sokushisa okungashisi, kuyilapho ukulungiswa kwesistimu yamanzi ashisayo kungenziwa ngamaqoqo ukuze kancane kancane kushintshe imishini ekhona, ukuze ingathinteki. ibhizinisi elivamile lehhotela. Njengengqalabutho kwezoguquko lokonga amandla ehhotela, i-Nobeth generator yenze uguquko oluyingqayizivele lokonga amandla ehhotela. Ihhotela lisebenzisa isistimu yokushisisa yesayensi ye-steam generator ukuze lithuthukise ukusebenza kahle, futhi izinzuzo zokonga amandla zinkulu kakhulu. Ngokwesilinganiso, ihhotela ngemva kokulungiswa lingonga amandla engeziwe nezindleko zokusebenza ngonyaka.
