1.Le cala langaphandle lensimbi elisindayo lenzelwe ngokukhethekile ama-boilers omusi wezimboni, ahlinzeka ngokuvikeleka okuqinile kwezingxenye eziyinhloko.
2.Yakhiwe ngensimbi yekhwalithi ephezulu egoqelwe ngamakhaza, iqinisekisa ukuqina nokuphila isikhathi eside ezindaweni ezidinga kakhulu zezimboni.
3.Ikesi lenzelwe ukuthuthukisa ukusebenza kukabhayela ngokugcina ukufakwa kwe-thermal okungaguquki.
4.Idizayini yayo ethambile, eyimodulayo ivumela ukufinyelela kalula ezingxenyeni zangaphakathi ngesikhathi sokulungiswa kanye nokusevisa.
I-5.Ifanele amamodeli ahlukahlukene we-boiler, ikesi lenziwe ngokwezifiso ukuze lihlangabezane nezidingo ezithile zobukhulu kanye nokusebenza.
