電熱水器如何選購

1.按預算選擇

資(zi)金是否充(chong)足是選擇產(chan)品(pin)首(shou)要(yao)面對的一關(guan)，儲水(shui)式電(dian)熱(re)水(shui)器(qi)的價格區間從幾百到幾千不等，

2. 根據容量選購

容量也(ye)是決定(ding)舒適度(du)的一個因(yin)素，合適的容量可以解決不(bu)必(bi)要(yao)的問題(ti)。

容量(liang)也是(shi)決定舒適(shi)度的(de)(de)一(yi)個(ge)(ge)因素，合適(shi)的(de)(de)容量(liang)可以解決不必(bi)要的(de)(de)問題。40-50L適(shi)合一(yi)個(ge)(ge)人，60-80L適(shi)合兩個(ge)(ge)人，三(san)口之家選擇80L及(ji)以上容量(liang)的(de)(de)熱(re)水器。

電熱水器優點與缺點

電熱(re)(re)(re)器(qi)(qi)優(you)點：1、電熱(re)(re)(re)水(shui)(shui)器(qi)(qi)相比之下大的(de)優(you)點是(shi)安裝便捷(jie)性，沒有燃(ran)氣的(de)商住(zhu)房優(you)先考慮；2、電熱(re)(re)(re)水(shui)(shui)器(qi)(qi)安裝位置不(bu)受(shou)約(yue)束，不(bu)像燃(ran)氣熱(re)(re)(re)水(shui)(shui)器(qi)(qi)一定要(yao)放在煤氣管道(dao)附近；3、即(ji)開即(ji)熱(re)(re)(re)，當然，這個(ge)的(de)前提是(shi)你家(jia)用(yong)的(de)是(shi)即(ji)熱(re)(re)(re)式電熱(re)(re)(re)水(shui)(shui)器(qi)(qi)；4、電熱(re)(re)(re)器(qi)(qi)不(bu)會有燃(ran)氣中(zhong)du的(de)風險。

電(dian)(dian)(dian)熱器(qi)(qi)缺(que)點(dian)：1、儲水(shui)(shui)(shui)式電(dian)(dian)(dian)熱水(shui)(shui)(shui)器(qi)(qi)因為有儲水(shui)(shui)(shui)桶，所(suo)以占用(yong)(yong)空間大，能(neng)隱(yin)藏設計是更好的了(le)；2、儲水(shui)(shui)(shui)式電(dian)(dian)(dian)熱水(shui)(shui)(shui)器(qi)(qi)有容積限制(zhi)，熱水(shui)(shui)(shui)用(yong)(yong)沒了(le)，需要花時間再(zai)燒；3、加(jia)熱成本相對(dui)比燃(ran)氣熱水(shui)(shui)(shui)器(qi)(qi)高(gao)；（一般來說一家三口日常使用(yong)(yong)，燃(ran)氣熱水(shui)(shui)(shui)器(qi)(qi)花費可能(neng)在500元左右，電(dian)(dian)(dian)熱器(qi)(qi)可能(neng)需要1300元左右）4、電(dian)(dian)(dian)器(qi)(qi)避免不了(le)的是漏(lou)電(dian)(dian)(dian)風險，同樣的電(dian)(dian)(dian)熱水(shui)(shui)(shui)器(qi)(qi)也存(cun)在漏(lou)電(dian)(dian)(dian)的安(an)全隱(yin)患。

容(rong)積(ji)式電熱(re)水(shui)器(qi)(qi)(qi)的原理是(shi)什么(me)？容(rong)積(ji)式電熱(re)水(shui)器(qi)(qi)(qi)是(shi)一種(zhong)利(li)用儲存在加熱(re)容(rong)器(qi)(qi)(qi)中的水(shui)，通過電能加熱(re)元件(jian)將水(shui)加熱(re)至高溫的熱(re)水(shui)器(qi)(qi)(qi)。其基本原理是(shi)：先在自(zi)來水(shui)管(guan)上安裝止回(hui)閥(fa)和進水(shui)口（注滿水(shui)），然后將電熱(re)水(shui)器(qi)(qi)(qi)內部(bu)的隔(ge)板分成冷(leng)水(shui)室(shi)和熱(re)水(shui)室(shi)兩(liang)部(bu)分，并(bing)在這(zhe)兩(liang)個室(shi)之間(jian)充入氮氣，起到(dao)防(fang)止水(shui)倒流作(zuo)用。

當接通電(dian)源時(shi)，電(dian)熱水器開始工(gong)作，依靠電(dian)阻發熱使置于(yu)各層的密封膠圈(quan)正(zheng)常升(sheng)溫(wen)，然(ran)后達到預(yu)定溫(wen)度(du)(du)。在整個過程(cheng)中，由于(yu)不斷地充入新(xin)鮮空(kong)氣以調節濕度(du)(du)，因(yin)此可長期保(bao)持衛生(sheng)、無(wu)異(yi)味、無(wu)污染。
