即熱式熱水器和儲水式熱水器哪個好

1、外觀與體積

儲水式(shi)電(dian)熱(re)水器(qi)帶一個大(da)水桶，通(tong)常40升(sheng)到100升(sheng)，安裝的(de)時候墻(qiang)壁需(xu)要(yao)是(shi)承重墻(qiang)，若裝在(zai)浴室還(huan)占地方，而且影響美觀。即熱(re)式(shi)的(de)熱(re)水器(qi)就(jiu)相對(dui)小巧精(jing)致(zhi)，通(tong)常就(jiu)是(shi)17寸液晶顯示器(qi)盒子這么(me)大(da)，不同的(de)外(wai)形，安裝方便(bian)。

2、功率、電壓

即熱式熱水器功(gong)率通常(chang)在(zai)5500瓦(wa)(wa)(wa)以上，廚(chu)房(fang)里(li)的(de)(de)(de)(de)小廚(chu)寶一般(ban)是5500瓦(wa)(wa)(wa)，用(yong)于洗(xi)手洗(xi)菜，而(er)洗(xi)澡用(yong)的(de)(de)(de)(de)熱(re)水(shui)(shui)器就(jiu)(jiu)(jiu)要(yao)6500瓦(wa)(wa)(wa)以上才(cai)能達到(dao)較(jiao)好的(de)(de)(de)(de)洗(xi)浴效果。儲水(shui)(shui)式(shi)的(de)(de)(de)(de)熱(re)水(shui)(shui)器通常(chang)1000瓦(wa)(wa)(wa)以上，比較(jiao)多的(de)(de)(de)(de)是2000瓦(wa)(wa)(wa)左右(you)。那即熱(re)式(shi)的(de)(de)(de)(de)熱(re)水(shui)(shui)器功(gong)率那么高是不是對電(dian)(dian)線(xian)電(dian)(dian)壓的(de)(de)(de)(de)要(yao)求也(ye)很高呢？其實是的(de)(de)(de)(de)，6500瓦(wa)(wa)(wa)到(dao)7500瓦(wa)(wa)(wa)的(de)(de)(de)(de)即熱(re)式(shi)的(de)(de)(de)(de)熱(re)水(shui)(shui)器要(yao)求4平(ping)方的(de)(de)(de)(de)專線(xian)，而(er)8500瓦(wa)(wa)(wa)的(de)(de)(de)(de)就(jiu)(jiu)(jiu)要(yao)求6平(ping)方的(de)(de)(de)(de)專線(xian)，目前市面上2005年以后的(de)(de)(de)(de)房(fang)子(zi)基本都(dou)配有4平(ping)方的(de)(de)(de)(de)專線(xian)。如(ru)果是5500瓦(wa)(wa)(wa)的(de)(de)(de)(de)小廚(chu)寶那就(jiu)(jiu)(jiu)只需2.5平(ping)方線(xian)，基本所有的(de)(de)(de)(de)家庭電(dian)(dian)線(xian)都(dou)符(fu)合(he)這要(yao)求。儲水(shui)(shui)式(shi)熱(re)水(shui)(shui)器也(ye)只需2.5平(ping)方線(xian)。在(zai)電(dian)(dian)壓要(yao)求方面，并不是功(gong)率高電(dian)(dian)壓就(jiu)(jiu)(jiu)必須高，功(gong)率=電(dian)(dian)壓*電(dian)(dian)流，即熱(re)式(shi)的(de)(de)(de)(de)也(ye)是用(yong)220伏。

3、安全性能

目(mu)前很多家庭(ting)認為即(ji)熱(re)式(shi)(shi)的熱(re)水器比(bi)儲水式(shi)(shi)的熱(re)水器更不安全，功率高(gao)(gao)(gao)更加容易漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)死(si)人(ren)(ren)，其實(shi)這(zhe)觀念是(shi)不對(dui)的。漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)跟電(dian)(dian)(dian)(dian)(dian)(dian)線質量有關系，即(ji)使(shi)是(shi)2.5平方的電(dian)(dian)(dian)(dian)(dian)(dian)線，如(ru)(ru)果不符(fu)合(he)國家標(biao)準，同樣容易漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)。即(ji)熱(re)式(shi)(shi)熱(re)水器的功率更高(gao)(gao)(gao)，但不是(shi)更容易漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)，其危(wei)險程度(du)跟家庭(ting)普通電(dian)(dian)(dian)(dian)(dian)(dian)器一樣高(gao)(gao)(gao)，只要漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)，一樣把人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)死(si)的。人(ren)(ren)的安全電(dian)(dian)(dian)(dian)(dian)(dian)壓承受能力是(shi)36伏(fu)，高(gao)(gao)(gao)于36伏(fu)的電(dian)(dian)(dian)(dian)(dian)(dian)壓都容易電(dian)(dian)(dian)(dian)(dian)(dian)死(si)人(ren)(ren)。另外即(ji)熱(re)式(shi)(shi)的熱(re)水器在(zai)防電(dian)(dian)(dian)(dian)(dian)(dian)方面也取得了(le)重要的技術突破，比(bi)如(ru)(ru)隔電(dian)(dian)(dian)(dian)(dian)(dian)墻、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)防漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)保護裝置等。

4、耗電量

耗(hao)電(dian)量=功率(lv)×時間，一(yi)千(qian)瓦(wa)用(yong)一(yi)小時就是一(yi)度電(dian)。很(hen)多(duo)人就覺得(de)儲水(shui)(shui)(shui)(shui)式(shi)在功率(lv)上是小很(hen)多(duo)的(de)，用(yong)電(dian)量肯定就少(shao)(shao)很(hen)多(duo)。其實從能量守恒規律來(lai)看(kan)，加(jia)熱(re)(re)這么多(duo)水(shui)(shui)(shui)(shui)到40℃用(yong)的(de)電(dian)量是一(yi)樣的(de)，從這個角度來(lai)看(kan)，其實即熱(re)(re)式(shi)與儲水(shui)(shui)(shui)(shui)式(shi)耗(hao)電(dian)差不(bu)多(duo)。但(dan)是儲水(shui)(shui)(shui)(shui)式(shi)有一(yi)個大水(shui)(shui)(shui)(shui)箱，內里(li)儲的(de)都(dou)是熱(re)(re)水(shui)(shui)(shui)(shui)，如果用(yong)不(bu)完，那一(yi)大桶(tong)熱(re)(re)水(shui)(shui)(shui)(shui)就得(de)浪費不(bu)少(shao)(shao)電(dian)，還要(yao)不(bu)斷保溫(wen)加(jia)熱(re)(re)，所以總體來(lai)說，儲水(shui)(shui)(shui)(shui)式(shi)熱(re)(re)水(shui)(shui)(shui)(shui)器(qi)對電(dian)的(de)浪費不(bu)亞于即熱(re)(re)式(shi)熱(re)(re)水(shui)(shui)(shui)(shui)器(qi)。

5、雙模雙核熱水器

有一種半(ban)儲(chu)(chu)水(shui)式的熱(re)(re)水(shui)器(qi)叫雙模雙核熱(re)(re)水(shui)器(qi)，它結合了(le)即(ji)(ji)熱(re)(re)式與儲(chu)(chu)水(shui)式的優點(dian)，即(ji)(ji)滿足一些客戶要(yao)求(qiu)快的需(xu)求(qiu)，又避(bi)免了(le)大(da)水(shui)箱熱(re)(re)水(shui)器(qi)的浪費。在這方(fang)面走在全國領先地位的是奧特朗開發(fa)的預(yu)即(ji)(ji)雙模機。

6、配置

儲水(shui)式(shi)(shi)熱(re)(re)水(shui)器一(yi)般配(pei)(pei)有混(hun)水(shui)閥，即熱(re)(re)式(shi)(shi)一(yi)般不需(xu)配(pei)(pei)混(hun)水(shui)閥。儲水(shui)式(shi)(shi)的混(hun)水(shui)閥可以調節(jie)熱(re)(re)水(shui)的熱(re)(re)度(du)，即熱(re)(re)式(shi)(shi)通(tong)過(guo)熱(re)(re)水(shui)器本身的功率(lv)溫度(du)調節(jie)系統控制出(chu)水(shui)溫度(du)。
