Yebo, ukuhlelela igeyza lakho isikhathi kungayonga imali, kodwa okongiwayo ngempela ngefiziksi kuphela kuncane kakhulu kunalokho abantu abaningi abakucabangayo. Emndenini ojwayelekile waseNingizimu Afrika, ukucisha igeyza ingxenye yosuku kukhipha ukonga kwe-thermodynamic okuncane okulinganiselwa ku-R30 kuya ku-R60 ngenyanga. Nokho, uma ufaka amathariff e-Time-of-Use kanye nesiphithiphithi sokucinywa kukagesi, ukuhlela okuhlakaniphile kuba nenzuzo enkulu—hhayi ngoba usebenzisa amandla amancane, kodwa ngoba uthenga amandla ngezikhathi ezishibhile futhi uvimbela imijikelezo yokushisa engenamsebenzi ngesikhathi kucinyiwe ugesi.

Ifiziksi: ukulahleka kokushisa uma limile kuqhathaniswa namandla okushisa kabusha

Kunenganekwane evamile eqhubekayo emakhaya aseNingizimu Afrika: "Kuthatha amandla amaningi ukushisisa kabusha igeyza elibandayo kunokuligcina lishisa." Lokhu akulungile ngokwe-thermodynamics. Ukulahleka kokushisa esitsheni kuhambisana ngqo nomehluko wezinga lokushisa phakathi kwamanzi angaphakathi nomoya ozungezile ongaphandle. Uma ucisha igeyza lakho, amanzi ayaphola, umehluko wezinga lokushisa uyancipha, kanti nesivinini sokulahleka kokushisa siyehla. Igeyza elipholile lilahlekelwa amandla amancane ayela emoyeni ozungezile kunelishisayo.

Nokho, okongiwayo ngempela kukhawulelwe ngokuqinile yikhwalithi yokuvikelwa kokushisa kwegeyza lakho. Ngaphansi kwe-South African National Standard (SANS) 151, igeyza lesimanje elinesilinganiso esithi B lamalitha angu-150 linokulahleka kokushisa uma limile okucishe kube ngu-1.5 kuya ku-1.9 kilowatt-hours (kWh) ngamahora angama-24 uma ligcinwa ku-60°C. Uma ucisha igeyza amahora angu-16 ngosuku, wehlisa izinga lokushisa eliphakathi lamanzi kuleso sikhathi, unciphise ukulahleka kokushisa uma limile ngamaphesenti angaba ngu-30%. Lokhu konga cishe u-0.5 kWh ngosuku. Ngethariff elijwayelekile likamasipala elingu-R3.50 nge-kWh, lokhu kusho ukonga kuka-R1.75 ngosuku, noma cishe u-R52 ngenyanga. Kuwukonga kwangempela, kodwa ngeke kunciphise ibhili yakho kagesi kodwana.

Inkinga eyengezwa ukucinywa kukagesi

Ukucinywa kukagesi kuphazamisa ukuhlela okulula. Uma usebenzisa ithayima elijwayelekile lomshini ebhodini lakho lokusabalalisa ugesi, ukucinywa kukagesi kwamahora amabili kuzohlehlisa iwashi lethayima ngamahora amabili (ngaphandle uma linebhethri lokusekela, elivame ukwehluleka ngemva kokucinywa okuphindaphindiwe). Lokhu kusho ukuthi igeyza lakho lingagcina selishisa ngamahora abizayo noma, okubi nakakhulu, lihluleke ukushisa ngaphambi kokuthi ugeze ekuseni.

Ngaphezu kwalokho, uma ukucinywa kukagesi kukuphoqa ukuthi ushisise igeyza lakho lifike ezingeni lokushisa eliphakeme (isibonelo, ukulikhuphula lisuke ku-60°C liye ku-70°C ukuze "ligcine" amandla okushisa amaningi ngesikhathi sokucinywa okude), wandisa ukulahleka kokushisa uma limile. Umehluko omkhulu wezinga lokushisa ukhulisa isivinini sokulahleka kokushisa, kususe ingxenye yalokho okongiwayo obuthemba ukukuthola.

Ukunqoba kwangempela kwezimali: amathariff e-Time-of-Use

Inzuzo yangempela yezimali yokuhlelela igeyza isikhathi eNingizimu Afrika imayelana nesikhathi, hhayi ne-thermodynamics. Omasipala baya ngokuya bedlulisela izakhamuzi kumathariff e-Time-of-Use (ToU), afana nethariff i-Home Flex yaseKapa. Ngaphansi kwalezi zakhiwo, ugesi osetshenziswa ngamahora abizayo (ngokuvamile ngo-06:00 kuya ku-09:00 nango-17:00 kuya ku-19:00 ezinsukwini zesonto) ukhokhiswa kakhulu kunangezikhathi ezingabizi.

I-elementi elijwayelekile legeyza lidonsa u-2 kW kuya ku-3 kW. Ukusebenzisa i-elementi elingu-3 kW amahora amabili ngesikhathi esibizayo kubiza kakhulu kunokulisebenzisa sekuhambile ubusuku noma emini. Ngokuhlela igeyza ukuthi lisebenze kuphela ngamahora angabizi, ungonga kalula u-R150 kuya ku-R300 ngenyanga ngomehluko wamathariff kuphela, ngisho noma isamba sama-kilowatt-hours asetshenzisiwe sihlala sifana ncamashi.

Okudingayo ukuze ulawule futhi uqinisekise okongiwayo

Ukuze uthole lokhu kongiwayo ngaphandle kokudela amanzi ashisayo, awukwazi ukwethembela kumathayima ayimpumputhe. Udinga uhlelo lokulawula oluhlakaniphile oluhlanganisa izinto ezintathu: ukuqashwa kukagesi ngesikhathi sangempela, ukuzwa izinga lokushisa, kanye nokwazi ngokucinywa kukagesi. Uma ufuna ukuklama noma ukufaka uhlelo olukwazi lelo zinga lokusebenzisana, izixazululo zethu ze-IoT yasekhaya zinikeza ihadiwe enembayo nezinhlaka zokuhlanganisa ezidingekayo ukuguqula lezi zibalo zibe ukonga okuzenzakalelayo.

Uhlelo oluhlakaniphile ngempela alusebenzi ngewashi kuphela. Luqapha izinga lokushisa langempela lamanzi ngenhla nangezansi kwesilinda. Uma amanzi esevele ku-55°C, luvimbela i-elementi ukuthi lingavuthi. Lubuye lubheke uhlelo lwendawo lokucinywa kukagesi nge-API ukuqinisekisa ukuthi imijikelezo yokushisa iqedwa ngaphambi nje kokuqala kokucinywa kukagesi, kunokuba iphazanyiswe iphakathi nendawo, okuchitha amandla emijikelezweni yokushisa engaphelele.

Ukuqhathanisa amasu

Ithebula elingezansi lichaza ukuthi amasu ahlukene okuphatha asebenza kanjani ngaphansi kwezimo ezijwayelekile zikamasipala waseNingizimu Afrika, kucatshangwa igeyza lamalitha angu-150 nesakhiwo esijwayelekile sethariff ye-Time-of-Use.

Ukufingqa: ukuhlelela igeyza lakho isikhathi kuyayonga imali, kodwa ukonga kwe-thermodynamic kokulicisha kuncane. Ukunqoba kwangempela kwezimali kusekuhleleni okuhlakaniphile okugwema amathariff abizayo kamasipala futhi okubhekana nezinhlelo zokucinywa kukagesi. Ukuze ukufeze lokhu, tshala imali ekuzweni okusebenzayo nasekulawuleni okuhlakaniphile kunokutshala kwithayima elilula, eliyimpumputhe.
