家用熱交換器解決了集體供暖家庭和冬天用熱水的難題。它的工作原理跟集體供熱的熱交換器原理相同。只是大小和樣式不同而已。供應半容積式換熱器可分為鑄鐵式，筒式，鋼制式，儲水式，板式。效果都不錯。鑄鐵式熱交換器 的體積大，重量重。半容積式換熱器廠家但是里(li)面(mian)的(de)(de)(de)銅(tong)管(guan)(guan)買之前可以(yi)打開(kai)檢查一下，不容易被商家(jia)(jia)坑騙，而(er)(er)且(qie)用(yong)過(guo)幾年(nian)銅(tong)管(guan)(guan)壞了(le)還可以(yi)更(geng)(geng)換(huan)。筒式的(de)(de)(de)體(ti)積小，交(jiao)換(huan)效率(lv)高(gao)。但用(yong)戶(hu)(hu)不能(neng)(neng)查看里(li)面(mian)銅(tong)管(guan)(guan)的(de)(de)(de)長度，也(ye)(ye)不能(neng)(neng)更(geng)(geng)換(huan)銅(tong)管(guan)(guan)，而(er)(er)且(qie)還不太美(mei)觀。鋼(gang)制式鋼(gang)制式體(ti)積有大有小。用(yong)戶(hu)(hu)也(ye)(ye)不能(neng)(neng)查看里(li)面(mian)銅(tong)管(guan)(guan)的(de)(de)(de)長度，而(er)(er)且(qie)不能(neng)(neng)更(geng)(geng)換(huan)銅(tong)管(guan)(guan)。但是比較(jiao)美(mei)觀。板式板式，體(ti)積很(hen)小，重量(liang)很(hen)小。熱(re)交(jiao)換(huan)效率(lv)很(hen)高(gao)。里(li)面(mian)無銅(tong)管(guan)(guan)。熱(re)交(jiao)換(huan)能(neng)(neng)力跟(gen)層(ceng)數有關。層(ceng)數看得見，摸得著(zhu)。水垢以(yi)上各種交(jiao)換(huan)器在使用(yong)過(guo)程中都會產(chan)生水垢。用(yong)了(le)幾年(nian)后會出(chu)現水流小，出(chu)水不是太熱(re)等情(qing)況。但在石家(jia)(jia)莊等地也(ye)(ye)出(chu)現了(le)專業除垢的(de)(de)(de)公司。通(tong)過(guo)專業除垢后也(ye)(ye)能(neng)(neng)跟(gen)新的(de)(de)(de)一樣。
