即熱式熱水器和儲水式熱水器哪個好

1、外觀與體積

儲水(shui)式電熱(re)水(shui)器帶一個大(da)水(shui)桶，通常(chang)40升到100升，安裝(zhuang)的時候墻(qiang)壁需要是(shi)承重(zhong)墻(qiang)，若裝(zhuang)在浴(yu)室還占地方(fang)，而(er)且(qie)影響(xiang)美觀。即熱(re)式的熱(re)水(shui)器就相對小巧精(jing)致，通常(chang)就是(shi)17寸液(ye)晶顯示器盒(he)子(zi)這么大(da)，不同的外形(xing)，安裝(zhuang)方(fang)便。

2、功率、電壓

即熱式熱水器功率(lv)(lv)通常(chang)在5500瓦以(yi)上(shang)，廚(chu)房里的(de)(de)小廚(chu)寶一般(ban)是(shi)(shi)(shi)5500瓦，用(yong)于洗(xi)手洗(xi)菜，而洗(xi)澡用(yong)的(de)(de)熱水(shui)(shui)器(qi)就(jiu)(jiu)要6500瓦以(yi)上(shang)才能(neng)達到(dao)較(jiao)好的(de)(de)洗(xi)浴效果(guo)。儲(chu)水(shui)(shui)式(shi)的(de)(de)熱水(shui)(shui)器(qi)通常(chang)1000瓦以(yi)上(shang)，比較(jiao)多的(de)(de)是(shi)(shi)(shi)2000瓦左右。那(nei)即(ji)熱式(shi)的(de)(de)熱水(shui)(shui)器(qi)功率(lv)(lv)那(nei)么高是(shi)(shi)(shi)不(bu)是(shi)(shi)(shi)對電(dian)線(xian)電(dian)壓(ya)的(de)(de)要求(qiu)也很高呢？其(qi)實是(shi)(shi)(shi)的(de)(de)，6500瓦到(dao)7500瓦的(de)(de)即(ji)熱式(shi)的(de)(de)熱水(shui)(shui)器(qi)要求(qiu)4平方的(de)(de)專(zhuan)線(xian)，而8500瓦的(de)(de)就(jiu)(jiu)要求(qiu)6平方的(de)(de)專(zhuan)線(xian)，目前市面(mian)上(shang)2005年以(yi)后的(de)(de)房子基本都配有(you)4平方的(de)(de)專(zhuan)線(xian)。如果(guo)是(shi)(shi)(shi)5500瓦的(de)(de)小廚(chu)寶那(nei)就(jiu)(jiu)只(zhi)需2.5平方線(xian)，基本所有(you)的(de)(de)家庭(ting)電(dian)線(xian)都符合這(zhe)要求(qiu)。儲(chu)水(shui)(shui)式(shi)熱水(shui)(shui)器(qi)也只(zhi)需2.5平方線(xian)。在電(dian)壓(ya)要求(qiu)方面(mian)，并不(bu)是(shi)(shi)(shi)功率(lv)(lv)高電(dian)壓(ya)就(jiu)(jiu)必須高，功率(lv)(lv)=電(dian)壓(ya)*電(dian)流，即(ji)熱式(shi)的(de)(de)也是(shi)(shi)(shi)用(yong)220伏(fu)。

3、安全性能

目前很多家庭認為(wei)即熱(re)(re)(re)(re)(re)式(shi)的(de)(de)(de)熱(re)(re)(re)(re)(re)水器比儲(chu)水式(shi)的(de)(de)(de)熱(re)(re)(re)(re)(re)水器更(geng)(geng)不(bu)(bu)安全(quan)，功(gong)率高(gao)更(geng)(geng)加容(rong)易漏(lou)(lou)電(dian)(dian)(dian)電(dian)(dian)(dian)死(si)人，其(qi)實(shi)這觀(guan)念是(shi)不(bu)(bu)對的(de)(de)(de)。漏(lou)(lou)電(dian)(dian)(dian)跟電(dian)(dian)(dian)線質量(liang)有(you)關系，即使是(shi)2.5平方的(de)(de)(de)電(dian)(dian)(dian)線，如果不(bu)(bu)符(fu)合國家標準，同樣容(rong)易漏(lou)(lou)電(dian)(dian)(dian)。即熱(re)(re)(re)(re)(re)式(shi)熱(re)(re)(re)(re)(re)水器的(de)(de)(de)功(gong)率更(geng)(geng)高(gao)，但不(bu)(bu)是(shi)更(geng)(geng)容(rong)易漏(lou)(lou)電(dian)(dian)(dian)，其(qi)危險程度跟家庭普通電(dian)(dian)(dian)器一樣高(gao)，只要(yao)(yao)漏(lou)(lou)電(dian)(dian)(dian)，一樣把人電(dian)(dian)(dian)死(si)的(de)(de)(de)。人的(de)(de)(de)安全(quan)電(dian)(dian)(dian)壓承受能力(li)是(shi)36伏(fu)，高(gao)于36伏(fu)的(de)(de)(de)電(dian)(dian)(dian)壓都容(rong)易電(dian)(dian)(dian)死(si)人。另外即熱(re)(re)(re)(re)(re)式(shi)的(de)(de)(de)熱(re)(re)(re)(re)(re)水器在防電(dian)(dian)(dian)方面也取得了重要(yao)(yao)的(de)(de)(de)技術突(tu)破(po)，比如隔(ge)電(dian)(dian)(dian)墻、電(dian)(dian)(dian)子防漏(lou)(lou)電(dian)(dian)(dian)保護裝置(zhi)等。

4、耗電量

耗(hao)電(dian)量=功(gong)率×時間(jian)，一(yi)(yi)千瓦用(yong)(yong)一(yi)(yi)小時就是(shi)(shi)(shi)一(yi)(yi)度(du)電(dian)。很(hen)多人就覺(jue)得儲水(shui)(shui)式(shi)(shi)在功(gong)率上是(shi)(shi)(shi)小很(hen)多的，用(yong)(yong)電(dian)量肯定就少很(hen)多。其(qi)實從能(neng)量守恒規律來(lai)看，加(jia)熱(re)(re)(re)(re)這么(me)多水(shui)(shui)到40℃用(yong)(yong)的電(dian)量是(shi)(shi)(shi)一(yi)(yi)樣(yang)的，從這個角(jiao)度(du)來(lai)看，其(qi)實即熱(re)(re)(re)(re)式(shi)(shi)與儲水(shui)(shui)式(shi)(shi)耗(hao)電(dian)差(cha)不(bu)多。但是(shi)(shi)(shi)儲水(shui)(shui)式(shi)(shi)有一(yi)(yi)個大(da)水(shui)(shui)箱(xiang)，內(nei)里儲的都(dou)是(shi)(shi)(shi)熱(re)(re)(re)(re)水(shui)(shui)，如(ru)果用(yong)(yong)不(bu)完，那一(yi)(yi)大(da)桶熱(re)(re)(re)(re)水(shui)(shui)就得浪(lang)費不(bu)少電(dian)，還要不(bu)斷(duan)保溫加(jia)熱(re)(re)(re)(re)，所以總體(ti)來(lai)說，儲水(shui)(shui)式(shi)(shi)熱(re)(re)(re)(re)水(shui)(shui)器對電(dian)的浪(lang)費不(bu)亞于即熱(re)(re)(re)(re)式(shi)(shi)熱(re)(re)(re)(re)水(shui)(shui)器。

5、雙模雙核熱水器

有一種半儲水(shui)(shui)(shui)式(shi)的熱(re)(re)水(shui)(shui)(shui)器叫雙(shuang)模(mo)雙(shuang)核(he)熱(re)(re)水(shui)(shui)(shui)器，它結合了即熱(re)(re)式(shi)與(yu)儲水(shui)(shui)(shui)式(shi)的優點，即滿足一些(xie)客戶要(yao)求快的需求，又避免了大水(shui)(shui)(shui)箱熱(re)(re)水(shui)(shui)(shui)器的浪費。在這(zhe)方面走在全國領(ling)先地位的是奧特朗開發的預即雙(shuang)模(mo)機(ji)。

6、配置

儲水(shui)(shui)(shui)式(shi)熱(re)(re)水(shui)(shui)(shui)器一(yi)(yi)般(ban)配有混(hun)(hun)水(shui)(shui)(shui)閥，即熱(re)(re)式(shi)一(yi)(yi)般(ban)不需配混(hun)(hun)水(shui)(shui)(shui)閥。儲水(shui)(shui)(shui)式(shi)的(de)混(hun)(hun)水(shui)(shui)(shui)閥可以(yi)調節熱(re)(re)水(shui)(shui)(shui)的(de)熱(re)(re)度(du)，即熱(re)(re)式(shi)通(tong)過熱(re)(re)水(shui)(shui)(shui)器本身的(de)功率溫度(du)調節系(xi)統(tong)控制出(chu)水(shui)(shui)(shui)溫度(du)。
