在買熱水器前，我(wo)們總會比較(jiao)分(fen)析(xi)兩者的(de)(de)(de)優(you)劣性，買一個相(xiang)對合適自己的(de)(de)(de)熱(re)(re)水(shui)器。下面為大家整理出(chu)電(dian)熱(re)(re)水(shui)器和燃(ran)氣熱(re)(re)水(shui)器兩者的(de)(de)(de)對比分(fen)析(xi)表，讓(rang)我(wo)們一起來看看燃(ran)氣熱(re)(re)水(shui)器與電(dian)熱(re)(re)水(shui)器哪個好吧。

比產熱水量

燃氣熱水(shui)(shui)器外殼上面都會(hui)標注著5L、7L、8L、10L等數字，這個(ge)并不是其能夠裝多少水(shui)(shui)量，而是指在(zai)1min之內將水(shui)(shui)溫度升(sheng)高25攝氏度所產生的熱水(shui)(shui)量。

電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)分為即(ji)熱(re)(re)(re)(re)式(shi)(shi)(shi)、速熱(re)(re)(re)(re)式(shi)(shi)(shi)以及(ji)儲(chu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)式(shi)(shi)(shi)三種(zhong)。即(ji)熱(re)(re)(re)(re)式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)的(de)出水(shui)(shui)(shui)(shui)(shui)(shui)(shui)量(liang)受到功(gong)率的(de)控制，通常7500w等同于(yu)5L的(de)燃(ran)氣(qi)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)出水(shui)(shui)(shui)(shui)(shui)(shui)(shui)量(liang)，即(ji)開即(ji)熱(re)(re)(re)(re)。速熱(re)(re)(re)(re)式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)是對儲(chu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)的(de)改進版，可以將預熱(re)(re)(re)(re)時(shi)(shi)間(jian)(jian)減(jian)少至(zhi)8~15分鐘，如果(guo)是速熱(re)(re)(re)(re)中的(de)預熱(re)(re)(re)(re)即(ji)熱(re)(re)(re)(re)雙模式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)，可以將30L的(de)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)出水(shui)(shui)(shui)(shui)(shui)(shui)(shui)量(liang)增加到180L，完全足夠6人左右(you)連續洗浴。儲(chu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)通常情況下水(shui)(shui)(shui)(shui)(shui)(shui)(shui)容量(liang)是30~90L或(huo)者更(geng)大。儲(chu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)式(shi)(shi)(shi)電(dian)(dian)(dian)熱(re)(re)(re)(re)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)器(qi)需(xu)要間(jian)(jian)隔半(ban)小時(shi)(shi)才(cai)能 加熱(re)(re)(re)(re)一罐(guan)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)，如果(guo)用完，則還(huan)需(xu)等待半(ban)小時(shi)(shi)。

比控溫穩定性

燃氣熱水器屬于快速加熱方(fang)式，能夠通過(guo)裝置(zhi)調整(zheng)溫度(du)，只(zhi)要在使用(yong)，則(ze)可一直保持此溫度(du)。

即熱(re)(re)(re)(re)(re)式(shi)(shi)(shi)電(dian)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)器(qi)控溫(wen)(wen)可(ke)分為機(ji)械式(shi)(shi)(shi)和恒(heng)溫(wen)(wen)式(shi)(shi)(shi)。機(ji)械式(shi)(shi)(shi)相(xiang)當于(yu)燃氣熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)器(qi)控溫(wen)(wen)，當調到適當的(de)位置(zhi)，以后的(de)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)也將一直保(bao)持這(zhe)溫(wen)(wen)度不變。恒(heng)溫(wen)(wen)式(shi)(shi)(shi)電(dian)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)器(qi)則(ze)可(ke)以精(jing)確選定(ding)出水(shui)(shui)(shui)(shui)溫(wen)(wen)度，屬于(yu)微電(dian)腦智能化(hua)控制。儲(chu)水(shui)(shui)(shui)(shui)式(shi)(shi)(shi)電(dian)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)器(qi)儲(chu)存的(de)一罐較高的(de)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)，在(zai)使(shi)用時(shi)用混水(shui)(shui)(shui)(shui)閥兌冷水(shui)(shui)(shui)(shui)調到適合溫(wen)(wen)度就可(ke)以了，在(zai)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)用完(wan)的(de)時(shi)候(hou)，水(shui)(shui)(shui)(shui)也會越來越冷。根據(ju)儲(chu)水(shui)(shui)(shui)(shui)式(shi)(shi)(shi)的(de)不便(bian)，速熱(re)(re)(re)(re)(re)式(shi)(shi)(shi)電(dian)熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)器(qi)改進了加熱(re)(re)(re)(re)(re)技術，使(shi)用預熱(re)(re)(re)(re)(re)即熱(re)(re)(re)(re)(re)雙(shuang)模(mo)式(shi)(shi)(shi)，當熱(re)(re)(re)(re)(re)水(shui)(shui)(shui)(shui)不夠熱(re)(re)(re)(re)(re)的(de)時(shi)候(hou)自(zi)動啟動即熱(re)(re)(re)(re)(re)功能，可(ke)以很好地保(bao)證出水(shui)(shui)(shui)(shui)溫(wen)(wen)度的(de)恒(heng)定(ding)。

比安全性

燃氣(qi)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)使(shi)(shi)用(yong)(yong)的(de)是液化(hua)石油氣(qi)或者天(tian)然氣(qi)，也有少數(shu)使(shi)(shi)用(yong)(yong)人工煤(mei)氣(qi)的(de)。這(zhe)些物(wu)質在燃燒過程中會產(chan)生有毒的(de)廢氣(qi)，在排放措施(shi)不(bu)通暢(chang)的(de)情況下很容(rong)易導致中毒死亡，非常危險。還(huan)有就是燃燒需(xu)要(yao)(yao)消耗氧(yang)氣(qi)，如(ru)果是浴室比(bi)較密封(feng)，則容(rong)易缺(que)氧(yang)，導致眩暈窒息。比(bi)如(ru)強排式(shi)和(he)煙道(dao)式(shi)兩種燃氣(qi)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)都(dou)是使(shi)(shi)用(yong)(yong)室內氧(yang)氣(qi)燃燒，安全(quan)隱患較大。而平衡(heng)式(shi)燃氣(qi)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)不(bu)使(shi)(shi)用(yong)(yong)室內氧(yang)氣(qi)，只要(yao)(yao)確保煙道(dao)無損壞漏(lou)氣(qi)，熱(re)(re)(re)水(shui)(shui)(shui)器(qi)正常工作還(huan)是安全(quan)的(de)。電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)主要(yao)(yao)需(xu)要(yao)(yao)解決漏(lou)電(dian)(dian)(dian)問題。目前(qian)，每臺電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)都(dou)配備了漏(lou)電(dian)(dian)(dian)保護(hu)開(kai)關，完全(quan)杜絕漏(lou)電(dian)(dian)(dian)導致事(shi)故發生。如(ru)果是先(xian)進(jin)高(gao)端一點的(de)電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)也有更多細致的(de)防(fang)護(hu)措施(shi)，比(bi)如(ru)是將主板灌封(feng)防(fang)水(shui)(shui)(shui)膠，按鍵防(fang)水(shui)(shui)(shui)等(deng)等(deng)，能比(bi)防(fang)水(shui)(shui)(shui)手機還(huan)要(yao)(yao)嚴密。
