Ukushisa kwangaphansi kugxilisa ukushisa kwakho ngokuyinhloko phakathi nobude lapho kusizakala khona umzimba womuntu, okuholela ekusebenzeni kahle kokushisa okuphezulu. Njengoba izinga lokushisa lamanzi ajikelezayo lidinga kuphela ukuthi libe phakathi kuka-40-50 degrees Celsius, izinga lokushisa lasendlini lingafinyelela ngaphezu kwama-20 degrees Celsius, linikeze ukushisa okufana nokunikezwa kwamanzi ashisayo.
Ngaphansi kwendlela yendabuko yamapayipi okushisa avelele kakhulu, ukushisa okungaphansi kunciphisa kakhulu amapayipi angaphandle, nawo wonke amapayipi angaphakathi avalelwe ngaphansi kwephansi. Lokhu kunciphisa ukulahlekelwa ukushisa, kuqede isenzakalo samazinga okushisa aphezulu phezulu naphansi. Ngaphezu kwalokho, ukushisisa kwangaphansi kuvumela ukulawula izinga lokushisa elizondiwe, okwenza amakhaya ngamunye akwazi ukonga amandla cishe ngama-30%, futhi lonke uhlelo lufinyelele cishe ku-40%. Lokhu kubaluleke kakhulu uma kubhekwa imithombo yamandla enciphayo etholakalayo namuhla.
