電熱水器選購技巧

看容量

選購儲水(shui)(shui)(shui)(shui)式電熱(re)水(shui)(shui)(shui)(shui)器的(de)時候，首先就要(yao)決定熱(re)水(shui)(shui)(shui)(shui)器的(de)容(rong)(rong)量大(da)小。熱(re)水(shui)(shui)(shui)(shui)器容(rong)(rong)量的(de)選擇主要(yao)取決于家(jia)庭人口和熱(re)水(shui)(shui)(shui)(shui)用(yong)量等(deng)因(yin)素。一般來說，1個人沐(mu)(mu)浴(yu)使(shi)(shi)用(yong)的(de)話，可選擇容(rong)(rong)積(ji)為(wei)30-40升電熱(re)水(shui)(shui)(shui)(shui)器:2-3人連續沐(mu)(mu)浴(yu)使(shi)(shi)用(yong)應選購40-50升電熱(re)水(shui)(shui)(shui)(shui)器:3-5人連續沐(mu)(mu)浴(yu)使(shi)(shi)用(yong)則需選購70-100升電熱(re)水(shui)(shui)(shui)(shui)器。此外，容(rong)(rong)量較(jiao)大(da)的(de)外形尺寸一般較(jiao)大(da)，因(yin)此，還需考慮(lv)安裝空間大(da)小。

什么是容(rong)積(ji)式(shi)熱(re)(re)(re)水(shui)器(qi)？容(rong)積(ji)式(shi)熱(re)(re)(re)水(shui)器(qi)是一種利用(yong)儲存在加(jia)熱(re)(re)(re)容(rong)器(qi)中(zhong)的水(shui)，通(tong)過燃(ran)燒加(jia)熱(re)(re)(re)元件(jian)(jian)將水(shui)加(jia)熱(re)(re)(re)至高溫的熱(re)(re)(re)水(shui)器(qi)。其基本原理(li)是：在自來水(shui)管上(shang)安(an)裝(zhuang)止回(hui)閥和進水(shui)口(kou)（注(zhu)滿水(shui)），電熱(re)(re)(re)水(shui)器(qi)安(an)裝(zhuang)，然后在容(rong)器(qi)中(zhong)插入電熱(re)(re)(re)管，通(tong)過電能加(jia)熱(re)(re)(re)元件(jian)(jian)將水(shui)加(jia)熱(re)(re)(re)至設(she)定(ding)溫度(du)。在整個加(jia)熱(re)(re)(re)過程(cheng)中(zhong)，由于不斷(duan)地充入新鮮空(kong)氣以調節(jie)濕度(du)，因此可長期保持衛(wei)生干凈、無(wu)異味、無(wu)污染。

容積式熱水器(qi)的(de)主要(yao)組(zu)成部(bu)分包括：1.外殼(ke)：用(yong)于保護內部(bu)元件(jian)，承(cheng)受(shou)使(shi)用(yong)過程(cheng)中的(de)壓(ya)力和耐腐蝕性。

2.加熱(re)(re)元(yuan)(yuan)件：包括電阻發熱(re)(re)管(guan)、陶瓷加熱(re)(re)元(yuan)(yuan)件等，用于將(jiang)水加熱(re)(re)至設(she)定溫度。

3.控(kong)制(zhi)系統：包(bao)括溫(wen)度傳感(gan)器、電磁閥、智(zhi)能(neng)芯(xin)片(pian)等，用于控(kong)制(zhi)加熱(re)元件的工作狀態，保證(zheng)水(shui)溫(wen)在(zai)設定范圍內。

4.水路系統：包括(kuo)進水管、出水管、排(pai)污管等，用于將自(zi)來(lai)水輸(shu)送至容(rong)器內部，同(tong)時(shi)將使用后(hou)的廢水排(pai)出。

5.安全(quan)保(bao)護裝(zhuang)置：包括超溫保(bao)護、干燒保(bao)護、漏電保(bao)護等(deng)，用于保(bao)護使用者的(de)安全(quan)。

總之，容積式熱(re)(re)水器(qi)(qi)是一種(zhong)利用儲存在加(jia)熱(re)(re)容器(qi)(qi)中的(de)(de)水，通(tong)過燃(ran)燒加(jia)熱(re)(re)元(yuan)件(jian)將水加(jia)熱(re)(re)至高溫(wen)的(de)(de)熱(re)(re)水器(qi)(qi)。它通(tong)過控(kong)制系(xi)統(tong)控(kong)制加(jia)熱(re)(re)元(yuan)件(jian)的(de)(de)工作狀態(tai)，電熱(re)(re)水器(qi)(qi)，保(bao)證水溫(wen)在設定(ding)范圍內，同(tong)時也具有安全保(bao)護裝(zhuang)置(zhi)，保(bao)護使用者的(de)(de)安全。

容積式電熱水器的使用(yong)壽命是多(duo)少年？

   由于(yu)家(jia)(jia)(jia)用(yong)(yong)電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)一(yi)(yi)(yi)般的工作環境(jing)都比(bi)較潮濕，電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)售后，使(shi)用(yong)(yong)時間長了，就有(you)(you)(you)(you)(you)可能(neng)會出(chu)現(xian)線(xian)路老化等情況。這樣對我們(men)使(shi)用(yong)(yong)容積(ji)式電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)會有(you)(you)(you)(you)(you)一(yi)(yi)(yi)定的危險性(xing)。因(yin)此，在(zai)(zai)安(an)(an)裝的時候要(yao)注意(yi)一(yi)(yi)(yi)定要(yao)安(an)(an)裝具有(you)(you)(you)(you)(you)“防電(dian)(dian)(dian)墻(qiang)技(ji)術(shu)”或者“水(shui)(shui)(shui)電(dian)(dian)(dian)分離(li)技(ji)術(shu)”的智能(neng)電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)。這種技(ji)術(shu)能(neng)有(you)(you)(you)(you)(you)效解決環境(jing)帶(dai)電(dian)(dian)(dian)問(wen)題。除此之(zhi)外，線(xian)路的接駁(bo)，安(an)(an)裝，安(an)(an)排(pai)設(she)置都有(you)(you)(you)(you)(you)合理。用(yong)(yong)戶應該(gai)選購合格具有(you)(you)(you)(you)(you)國家(jia)(jia)(jia)安(an)(an)全性(xing)能(neng)標(biao)志的電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)。在(zai)(zai)日常保養方便，家(jia)(jia)(jia)用(yong)(yong)電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)一(yi)(yi)(yi)般是(shi)直(zhi)接安(an)(an)裝在(zai)(zai)浴(yu)室，浴(yu)室都比(bi)較潮濕。所以我們(men)在(zai)(zai)使(shi)用(yong)(yong)完后，應該(gai)盡量讓浴(yu)室通(tong)風，吹(chui)干電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)。每年在(zai)(zai)使(shi)用(yong)(yong)之(zhi)前應該(gai)要(yao)做清(qing)潔(jie)工作，檢(jian)查各線(xian)路有(you)(you)(you)(you)(you)沒有(you)(you)(you)(you)(you)出(chu)現(xian)老化等跡象。如果遇到有(you)(you)(you)(you)(you)故障發生，一(yi)(yi)(yi)定要(yao)立即(ji)停(ting)用(yong)(yong)，并且(qie)盡快聯系相關的售后維修商上門維修。達到使(shi)用(yong)(yong)年限的家(jia)(jia)(jia)用(yong)(yong)電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)還是(shi)考慮淘汰，更換新電(dian)(dian)(dian)熱(re)(re)(re)水(shui)(shui)(shui)器(qi)(qi)，避免發生意(yi)外。

   理論(lun)上容(rong)積式電(dian)(dian)熱水器(qi)(qi)只要(yao)不出現漏水，都(dou)可以繼續使(shi)用(yong)，電(dian)(dian)熱水器(qi)(qi)哪(na)家好，但使(shi)用(yong)時間長了(le)，內部水垢多(duo)了(le)，占用(yong)內部容(rong)積，而且每次(ci)加熱先熱水垢再熱水，會越(yue)來(lai)越(yue)費電(dian)(dian)！建議7-8年更換電(dian)(dian)熱水器(qi)(qi)，別(bie)超過10年。
