Uma kukhulunywa ngokukhetha uhlelo olufanele lokushisisa amanzi ekhaya lesimanje, abaninzi bezindlu namuhla babhekana nezinketho eziningi kakhulu kunangaphambilini. Amathangi okugcina ajwayelekile, amayunithi angenamathangi, izinhlelo zamaphampu okushisa, nezixazululo ezisebenzisa igesi konke kuncintisana ukuze kutholakale ukunakwa, ngalinye lithembisa ukunethezeka nokulula ngezindlela ezahlukene. Phakathi kwalokhu, ama-heater amanzi agesi ahlala engesinye sezinqumo ezithandwa kakhulu emhlabeni wonke ngenxa yokusebenza kwawo kokushisa ngokushesha, ukwethembeka, kanye nezindleko eziphansi zokusebenza. Nokho, akubona wonke ama-heater amanzi agesi afanayo, futhi ubuchwepheshe obuwasebenzayo buguquke kakhulu eminyakeni yamuva. I-force type gas water heater, esebenzisa ifeni yemishini ukuphatha amagesi aphumayo, imele ukuthuthuka okukhulu kukokuphepha nokusebenza kahle. Kubhizinisi nabanikazi bezindlu abafuna isixazululo esisebenza kahle kakhulu, ukuqonda lobu buchwepheshe yisinyathelo sokuqala ekwenzeni utshalomali olunolwazi.

DOUBLEMAX, ngokusemthethweni eyaziwa nge-Doublemax Electrical Co., Ltd., isungule ukuthi ingumkhiqizi ohamba phambili wama-heater amanzi asebenza ngegesi asebenza kahle kakhulu kanye nezinto zokupheka zasekhishini ezisezingeni eliphezulu eminyakeni eyishumi edlule. Kusukela ngo-2012, inkampani yakhe igama lokwakha ngendlela entsha, ukuqinisekisa ikhwalithi ngokuqinile, nokusebenzisana nomhlaba wonke, ithole ukwethenjwa kwemindeni engaphezu kwezigidi ezingama-20 emazweni angaphezu kwama-75. Uhlu olubanzi lwemikhiqizo yenkampani luhlanganisa imikhiqizo engu-958 ehlanganisa izigaba eziyi-11, kusukela kuma-range hood nama-gas stove kuya ezinhlelweni zokushisisa amanzi ezithuthukile. Kulesi sihloko, sizobheka ngokujulile i-force type gas water heater, ikakhulukazi sigxile kuma-DOUBLEMAX forced draft condensing gas water heaters. Sizohlola ukuthi ubuchwepheshe busebenza kanjani, kungani bonga amandla, nokuthi yini ehlukanisa i-DOUBLEMAX kwezinye izinketho zomkhiqizi wama-gas water heater. Ekugcineni, uzobe usunokuqonda okuphelele kokuthi kungani ubuchwepheshe be-condensing buguqula imboni yokushisisa amanzi nokuthi bungakusiza kanjani.

Ezingeni eliyisisekelo, ihetha yamanzi eshisa ngogesi enesiphefumulo (force type gas water heater) iwumshini ophehla ngogesi (gas-fired appliance) osebenzisa ifeni kagesi noma i-blower ukuze iphoqe izintuthu zomlilo ukuba ziphume ngohlelo oluthile lokukhipha umoya (vent system). Ngokungafani nezinhlobo ezithembela ekukhuphukeni kwemvelo komoya oshisayo ukuze zikhiphe izintuthu ngoshimula, idizayini yokuphoqa (forced draft design) ikhipha ngokuqondile izintuthu zibe ziphuma endlini. Lokhu kusiza ngemishini kwenza inqubo yokukhipha umoya ilawuleke kakhulu, ibe nokubikezela, futhi isebenze kahle ezimweni eziningi zokufaka. Ifeni iphinde ivumele umshini ukuba udonse umoya owanele wokuphehla, okwenza inqubo yokushisa isebenze kahle futhi kunciphise ukukhiqizwa kwezinto eziyingozi ezifana ne-carbon monoxide. Ngenxa yalezi zinzuzo, ukwakheka kokuphoqa (force type configuration) sekuyindinganiso yezimboni kumayunithi esimanje asebenza kahle kakhulu (high-efficiency condensing units). Kubalulekile ukuthi abathengi baqaphele ukuthi le ndlela eqhutshwa ifeni ihluke ngokuphelele ezinhlelweni ezisebenza ngokwemvelo ezitholakala kumahetha amadala, futhi umehluko uhumushela ngqo ekusebenzeni nasekuphepheni.

Umehluko phakathi kohlobo lwe-force type kanye ne-natural draft heater yamanzi udlula nje ukuba khona kwefeni. Kuhlelo lwe-natural draft, igumbi lokushisela lincike kumehluko wokushisa phakathi kwegesi ezishisayo eziphumayo nomoya opholile wangaphandle ukuze kudaleke umsinsi wokukhuphuka othwala amagesi aphume. Lolu hlelo lulula futhi alubizi, kodwa ludinga ushimula omude ome mpo futhi lulahlekelwa kakhulu ukushisa njengoba amagesi ashisayo ephuma. I-force type gas water heater, ngokuphambene, isebenzisa igumbi lokushisela elivalekile kanye nefeni yokukhipha umoya enamandla engakwazi ukuphusha izinto eziphumayo ngamapayipi e-PVC amade avundlile.
