Ngati ife kulankhula za mmene kusankha khoma-wokwera kukatentha, muyenera kusankha mtundu wanji mukufuna: osakwatiwa-dera kapena ziwiri dera. Kenako chida cha chofunika kudziwa mphamvu zoyenera. Zimakhala zosavuta, lalikulu limodzi mita dera chipinda ndi kutalika muyezo denga ayenera kukhala 100 Watts. chikhalidwe n'kofunika kuti nyumba si wosanganiza ndi zipinda unheated. Ngati mukufuna kutenthetsa ngodya chipinda ndi mazenera awiri, ndiye pa mita lalikulu uzikhala pa 150 Watts mphamvu. Ngati pali kukayika kulikonse kuti kulondola kwa kuwerengetsera kuti munapanga nokha, inu mukhoza kutenga thandizo la alangizi akatswiri kugwira ntchito mu shopu.
Ngati mukufuna kugula khoma wokwera kukatentha ndipo tentatively anaganiza mphamvu chofunika, ndiye tingaganizire nkhani zina. Mfundo ina yofunika zokhudza ntchito mawu a madzi otentha. Ndi yosavuta zokwanira. Dinani madzi ukuyenda pa mlingo wa malita 400 pa ola limodzi. Kaperekedwe kukatentha zimafuna ntchito yokha. Ngati pali wina zochepa chabe pamalangizo mfundo ya madzi otentha akukwana index wa malita 6,6 pa mphindi. Pamene ntchito malo ogulitsira madzi ziwiri chida anfunika kubala madzi otentha pa mlingo wa malita 13,2 pa mphindi imodzi kapena zambiri.
Ngati mukuganiza khoma wokwera kukatentha, ndi kuchuluka kwa madzi kusiya bwino, m'pofunika kudziwa kutentha. Popeza ife kusamba m'manja ndi mbale, madzi osamba osati madzi otentha ndipo madzi ofunda, ndiye palibe kugula chipangizo, amene adzakhala ansangala izo. Yabwino ambiri kutentha ndi madigiri 40. Aliyense khoma wokwera kukatentha mu makhalidwe awo limapangidwa zokhudza osiyanasiyana kutentha madzi otentha, mwachitsanzo, 35-60 madigiri Celsius, ndi chizindikiro Deuteronomo 25 kapena 30. chiwerengero Izi zikusonyeza kusiyana pakati pa madzi ukubwera ozizira mu makina ndi otentha analandira pa linanena bungwe.
Pamwamba anafotokoza awiri khoma wokwera kukatentha. Ngati ife kulankhula za umodzi-dera chimake, tisaiwale kuti zochokera yekha mavuto magetsi. Atatero, sangathe kupereka nyumba kapena nyumba ndi madzi otentha, kotero si monga wamba pakati ogula. Boilers mpweya khoma kufunika awiri ndi wamkulu kwambiri. Iwo omasuka ndithu, chifukwa mosavuta wokwera pa khoma, sizikusoweka kwambiri mpata iwo. ntchito yawo yaikulu ndi luso osati kutenthetsa chipinda, komanso kupereka madzi otentha. Popeza njira izi ndi mosalekeza kwambiri, nthawi zambiri anasankhidwa ntchito m'nyumba wakunja kwatawuni.
Pa nthawi, wotchuka kwambiri pakati ogula boilers kampani Ferroli, amene wakhala mtsogoleri osati Russia komanso dziko kupanga zida kwa magetsi. Ndi makhalidwe a mankhwala a mtundu uwu monga zodalirika, high quality, kasamalidwe mabuku ndi mphamvu kasinthidwe. Choncho mtengo wa mankhwala a wopanga kawirikawiri ngakhale poyerekeza anthu Anzawo European.
