Ibhodlela lamanzi elivinjiwe cishe liwumkhiqizo odingekayo ekuphileni kwethu kwansuku zonke.Kungakhathaliseki ukuthi isetshenziselwa ukugcina ukushisa noma ukugcinwa okubandayo, idume kakhulu.
Isinye sebhodlela lamanzi elivalekile lenziwe ngengilazi enezingqimba ezimbili.Zombili izingqimba zengilazi zigcwele isiliva, njengesibuko, esingabonisa imisebe yokushisa emuva futhi sinqamule indlela yemisebe yokushisa.
I-vacuum phakathi kwezingqimba ezimbili zengilazi ku-thermos ibhubhisa izimo ze-convection conduction.Ukusetshenziswa kwesivalo sebhodlela lamanzi okugcina ukushisa okungelula ukudlulisa ukushisa kunqamula indlela ye-convection kanye nokudlulisa ukushisa.
Uma yomithathu imigwaqo yokudlulisa ukushisa ivinjiwe, ukushisa kungagcinwa isikhathi eside.Kodwa-ke, ukushisa okushisayo kwe-thermos akukude kakhulu.Kusekhona ukushisa okungaphuma, ngakho-ke isikhathi sokushisa esishisayo se-thermos sinomkhawulo othile.
Isembozo sebhodlela lamanzi angenalutho singagcina izinga lokushisa lamanzi ebhodleleni, sinqume ukushintshanisa okubandayo nokushisa phakathi kwebhodlela nangaphandle kwebhodlela.
Uma ufaka iqhwa ku-thermos ngokushesha, ukushisa ngaphandle ngeke kugijime ebhodleleni kalula, futhi iqhwa ngeke lincibilike kalula.
Ibhodlela lamanzi elivalekile liwusizo kakhulu, elingonga kokubili ukushisa nokubanda.
