Enye yezinzuzo zokushisa ngokhuni ukuthi isitofu esisodwa kuphela singasetshenziswa kuzo zonke izidingo. Ngaphezu kokusigcina sifudumele, imishini yokubasa izinkuni ingapheka ukudla, yomise izingubo, futhi ithose izinzwane ezibandayo. Kodwa bekungeke yini kube yinto enhle uma lelo bhokisi elimnyama lingageza ngamanzi ashisayo?
Eqinisweni, ama-heater amanzi okushisa izinkuni zasekhaya awayona into entsha... eminyakeni engaphezu kwekhulu edlule, izitofu eziningi zazinezinamathiselo zamathangi. Kodwa-ke, ukufika kwama-burners okhuni “avaliwe” kanye nezinhlelo zamanzi ezicindezelwe kubeke iningi lamasu amadala okushisa esitsheni sangemuva futhi izindlela ezintsha ezisekelwe emijikelezweni evaliwe sezithuthukisiwe.
Izesekeli eziningi zokufudumeza amanzi zisebenzisa ama-heat exchanger afakwe ebhokisini lomlilo noma kushimula wemishini. Isibonelo esihle kakhulu sezentengiselwano sale ndlela sisebenza kahle kakhulu. Uma isithando somlilo sisebenza cishe usuku lonke, singahlinzeka ngamanzi ashisayo ekhaya lonke. Kodwa-ke, ukuze kuphephe, lawa madivayisi avame ukwenziwa ngensimbi engagqwali (impahla ebizayo) futhi kumele ahlolwe ingcindezi ukuqinisekisa ukuthi angakwazi ukumelana namazinga okushisa aphezulu kakhulu angatholakala ohlelweni lokufudumeza. Ngakho-ke, i-heat exchanger yangaphakathi enhle iza nentengo ephezulu. Ngakolunye uhlangothi, izinto zangaphakathi ezenziwe ekhaya zaziwa ngokuqhuma komusi oshisayo.
Futhi, ukukhipha ukushisa ebhokisini lomlilo noma esitovini sezinkuni kungaba nomphumela omubi: ukukhipha i-Btu ngqo emlilweni (usebenzisa i-firebox exchanger) kunciphisa ukusebenza kahle kokushisa… uma imikhiqizo yokusha okungaphelele ipholiswa ngaphansi kwezinga lokushisa lapho ihlangana khona (kungaba ngegumbi lomlilo noma i-chimney heat exchanger), kungenzeka ukunqwabelana okukhulu kwe-creosote. Ungaphazami, ukuhlanganiswa komlilo we-chimney kanye ne-heat exchanger egcwele amanzi kungadala inhlekelele.
Siqaphela iqiniso lokuthi akukho ukudla kwasemini okungakhokhelwa, sathatha indlela elondolozayo yokuklama isinamathiselo sethu sokushisa amanzi esitovini sokhuni. Esikhundleni sokufaka i-exchanger ngaphakathi kwe-heater noma i-chimney, sanamathisela eyodwa ngaphandle kwebhokisi lomlilo. Ngokwamukela leli cebo, sigweme noma yiziphi izinguquko ezinkulu ku-heater, okugcina ukugunyazwa kwe-Underwriters Laboratories. Okubaluleke kakhulu, izinqubo eziningana zokuphepha esesizikhulumile kakade ziyahlangatshezwa: izinga lokushisa elitholakala ngaphandle kwe-heater enclosure ngeke libilise amanzi (inqobo nje uma uketshezi luhlala lujikeleza), ukushisa okusetshenziselwa ukushisa amanzi kukhishwa yi-heater noma kunjalo, ngakho akukho ukushisa okweqile okuphuma ebhokisini lomlilo.
Isixhumi sethu sokushisa amanzi siqukethe ipayipi yethusi elingamamitha angu-1/4 kuphela elihlanganiswe ku-drywall egcwele iParis. Izinto ezisekelwe ku-gypsum zisiza ukusabalalisa ukushisa ngokulinganayo kuma-coil futhi zivumela i-exchanger ukuthi ixhumane ngqo nomzimba wesithando ngaphandle kokushisa ngokweqile. (Singathanda ukubonga u-Ed Walkinstik ngesiphakamiso.) I-assembly ibopha ohlangothini olulodwa lwesifudumezi bese ixhuma ku-heater yamanzi engamalitha angu-42 ephinde yasetshenziswa (sisebenzise i-heater yamanzi enezinto zokusha kodwa ibhokisi elingangeni msindo). Njenge-solar preheater.
Iphampu engamalitha ayi-10 ngomzuzu efakwe emseleni wokushisa ijikeleza amanzi nge-coil bese ibuyela ku-"T" ngaphansi nje kwevalvu yokusiza phezulu kwethangi (le valve igcinwe njengesinyathelo sokuphepha). Amanzi abandayo angena esitsheni ngomnyango ojwayelekile, kanti amanzi afudumele ngokhuni angena esifudumezi sikagesi esivamile ngomnyango wokushisa ojwayelekile. Zonke izintambo zigqunywe kahle nge-foam ephakeme enobukhulu obuyi-intshi eyodwa.
Vele, uma amanzi ejikeleza njalo, ukushisa kungalahlekela esitovini uma kungekho umlilo ovuthayo. Ukuze avimbele lokhu, umcwaningi uDennis Burkholder ufake izilawuli zokuvula/ukuvala ngokuzenzakalela ku-thermostat ye-line-voltage air conditioner exhunywe entanjeni yamandla yephampu. (Ungasebenzisa futhi isilawuli sokushisa/sokupholisa umoya esivamile, esisethwe kwimodi yokupholisa.) I-thermostat ifakwe odongeni oluqhele ngamamitha amathathu ukusuka ku-heater, cishe ngamamitha ukusuka phezulu kwayo. Lapho izinga lokushisa lomoya lifinyelela ku-80°F, isilawuli sama-volt angu-120 sivula iphampu bese amanzi eqala ukushisa. Lapho izinga lokushisa lehla laya ku-76°F, inkinobho yokuhlukanisa eyakhelwe ngaphakathi iyayicima futhi i-circulator.
Izingxenye zesistimu yokushintshanisa ukushisa ziboniswe emidwebweni enamathiselwe, kodwa-ke konke ukufakwa kudinga izinguquko ezithile ebukhulu obuyisisekelo. Isibonelo, uma isithando sakho sikhulu kunesethu, ungandisa iphaneli ngokwanele ukuthola ikhoyili ephelele engamamitha angu-60 yepayipi yethusi elithambile elingu-1/4″ ngaphakathi kohlaka olukhulu lokushintshanisa. Kodwa-ke, labo abanezifudumezi ezincane kuzodingeka basebenzise izintambo ezincane.
Kunoma ikuphi, kulula kakhulu ukusebenzisa ipayipi njengoba ligoqiwe ukuze lithuthwe. Sifaka nje ucingo olugoqiwe ohlakeni bese sigoba ipayipi ngobumnene ukuze sigcwalise unxande. Izinto eziguquguqukayo zingagotshwa zibe yi-radius engaba ngu-1-1/2 amayintshi ngaphandle kokugoba, ngakho-ke akunzima ukuziphoqa zibe “izindawo ezishisayo” ezingaba khona. Sisebenza kusukela onqenqemeni lwangaphandle ngaphakathi, sinamathisela ama-coil ku-backplane njengoba siqhubeka. (Ngaphandle kwezintambo zokubopha indandatho yangaphandle yepayipi, yonke into yayifuna ukuphuma ohlakeni.)
Ngemva kokuba amapayipi ethusi esatshalaliswe ngokulinganayo ngaphakathi kohlaka, hlanganisa ungqimba oluncane lwe-plaster ye-paris bese uthela ingxube ohlakeni. Lengisa indawo ngokusebenzisa irula phezu kwe-engela yensimbi bese uvumela izinto zome izinsuku ezimbalwa. Iphaneli linganamathiselwa ohlangothini lwesithando somlilo bese umugqa ongu-1/4 intshi ungaxhunywa epayipini elingu-1/2 intshi lethangi lokushisa kusengaphambili.
Senze ukuhlolwa okude ukuze sithole ukucushwa okusebenza kahle kakhulu kweswishi futhi sizinike ukuzethemba kokuthi imishini izosebenza ngokuphephile. Isibonelo, ukuze sibone ukuthi kuzokwenzekani uma ugesi uphela uvala ipompo yethu, sivale ipayipi eliphuma ethangini lokushisa kusengaphambili futhi safaka i-pressure gauge ku-relief valve. Ingcindezi ephezulu kakhulu esakwazi ukuyithuthukisa ohlelweni yayiyi-3 PSI…lokho kungemuva kokuba i-Atlanta Stove Works Catalytic yethu imise ukugeleza amahora angu-8 ngesivinini esiphezulu kakhulu sokusha!
Ngaphezu kwalokho, ukuze sithole ukuthi ukushintshaniswa kokushisa komoya ohamba ngezindonga zesithando somlilo kwakukhuthazwa yini emazingeni angenempilo, sihlole ingaphakathi lebhokisi lesithando somlilo nsuku zonke ukuthola ukwanda kokwakheka kwe-creosote. Asitholanga mehluko ekubukekeni noma ekujuleni kwamadiphozithi kunoma yiziphi izindonga ezine, okuphakamisa ukuthi ama-exchangeers ayethola amandla akhanya kakhulu avela ezindongeni zesithando somlilo sangaphandle. (I-ceramic kungenzeka ukuthi idlale indima ethile yokuvikela, isusa ukuqhutshwa komoya ohambayo okwandisiwe.)
Ingakanani amanzi ashisayo ezokhiqizwa yi-exchanger? Nokho, emjikelezweni ojwayelekile wamahora angu-7, besizofaka amakhilogremu angu-55 kuya kwangu-60 ezinkuni ku-catalyst yase-Atlanta, okuzophakamisa okuqukethwe yithangi elingamalitha angu-42 kuye cishe ku-140°F. Leli zinga lokusha elingamakhilogremu angu-8 ngehora cishe liphakeme kancane kunalokho abantu abaningi abakusebenzisayo, ngakho-ke ungathola amanzi ashisayo amancane kancane kusuka kudivayisi efanayo. Vele, uma uqhubeka uvutha kakhulu usuku lonke, inani lamahora angu-24 kufanele libe amanzi ashisayo anele angaphezu kwamalitha ayi-100 ngosuku. Ngisho noma uvame ukusebenzisa isitofu sakho “esivaliwe,” lolu hlelo luzonciphisa kakhulu izindleko zakho zikagesi.
Kuye ngobukhulu bomndeni wakho kanye nokusetshenziswa kwamanzi yiwo wonke umuntu, lolu hlelo lungaqeda izindleko zakho zamanzi ashisayo asebusika. Ngakho-ke uma ungathola izinkuni ngemali ephansi kakhulu kunenani elilinganayo likagesi noma igesi, amandla owasebenzisayo ukushisa amanzi esitofini sakho sezinkuni (ngaphandle kwesikhala, vele, ukushisa okuzonikezwa yidivayisi) kuzoba kuhle kakhulu. Invest. Ngaphezu kwalokho, uzojabula ukwazi ukuthi uthathe elinye igxathu lokushintsha imithombo yamandla engavuseleleki.
Sekuyiminyaka engama-50 ku-MOTHER EARTH NEWS, sisebenzele ukuvikela izinsiza zemvelo zomhlaba ngenkathi sikusiza ukuthi wonge izinsiza zezimali. Uzothola amathiphu okunciphisa izikweletu zakho zokushisa, ukutshala imikhiqizo emisha, yemvelo ekhaya, nokuningi. Yingakho sifuna ukuthi wonge imali nezihlahla ngokubhalisela uhlelo lwethu lokonga ngokuzenzakalelayo olusebenzisa umhlaba.
