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)器帶一個大水(shui)桶，通常40升到100升，安裝的(de)時候(hou)墻壁需要是承重墻，若裝在浴室還占(zhan)地方，而且(qie)影響美觀。即熱(re)式的(de)熱(re)水(shui)器就(jiu)相(xiang)對小巧精致(zhi)，通常就(jiu)是17寸液晶顯示器盒子這么大，不同(tong)的(de)外(wai)形(xing)，安裝方便。

2、功率、電壓

即熱式熱水器功(gong)(gong)率(lv)通(tong)常在5500瓦(wa)(wa)以(yi)上，廚(chu)房里(li)的(de)(de)(de)小廚(chu)寶(bao)一般(ban)是(shi)5500瓦(wa)(wa)，用(yong)于洗(xi)手洗(xi)菜，而(er)洗(xi)澡(zao)用(yong)的(de)(de)(de)熱(re)(re)水(shui)器(qi)就要(yao)6500瓦(wa)(wa)以(yi)上才能達到(dao)較好(hao)的(de)(de)(de)洗(xi)浴(yu)效果(guo)。儲(chu)水(shui)式(shi)的(de)(de)(de)熱(re)(re)水(shui)器(qi)通(tong)常1000瓦(wa)(wa)以(yi)上，比(bi)較多的(de)(de)(de)是(shi)2000瓦(wa)(wa)左右。那(nei)即熱(re)(re)式(shi)的(de)(de)(de)熱(re)(re)水(shui)器(qi)功(gong)(gong)率(lv)那(nei)么(me)高(gao)是(shi)不是(shi)對電線(xian)(xian)(xian)電壓(ya)的(de)(de)(de)要(yao)求(qiu)(qiu)也很高(gao)呢？其實是(shi)的(de)(de)(de)，6500瓦(wa)(wa)到(dao)7500瓦(wa)(wa)的(de)(de)(de)即熱(re)(re)式(shi)的(de)(de)(de)熱(re)(re)水(shui)器(qi)要(yao)求(qiu)(qiu)4平(ping)(ping)方(fang)的(de)(de)(de)專線(xian)(xian)(xian)，而(er)8500瓦(wa)(wa)的(de)(de)(de)就要(yao)求(qiu)(qiu)6平(ping)(ping)方(fang)的(de)(de)(de)專線(xian)(xian)(xian)，目前(qian)市(shi)面(mian)上2005年以(yi)后(hou)的(de)(de)(de)房子基(ji)本都配(pei)有(you)(you)4平(ping)(ping)方(fang)的(de)(de)(de)專線(xian)(xian)(xian)。如果(guo)是(shi)5500瓦(wa)(wa)的(de)(de)(de)小廚(chu)寶(bao)那(nei)就只(zhi)需2.5平(ping)(ping)方(fang)線(xian)(xian)(xian)，基(ji)本所有(you)(you)的(de)(de)(de)家庭電線(xian)(xian)(xian)都符(fu)合這要(yao)求(qiu)(qiu)。儲(chu)水(shui)式(shi)熱(re)(re)水(shui)器(qi)也只(zhi)需2.5平(ping)(ping)方(fang)線(xian)(xian)(xian)。在電壓(ya)要(yao)求(qiu)(qiu)方(fang)面(mian)，并不是(shi)功(gong)(gong)率(lv)高(gao)電壓(ya)就必須高(gao)，功(gong)(gong)率(lv)=電壓(ya)*電流(liu)，即熱(re)(re)式(shi)的(de)(de)(de)也是(shi)用(yong)220伏。

3、安全性能

目前(qian)很多家(jia)庭認為即(ji)(ji)熱(re)(re)(re)(re)式(shi)的(de)(de)熱(re)(re)(re)(re)水(shui)器(qi)(qi)比儲水(shui)式(shi)的(de)(de)熱(re)(re)(re)(re)水(shui)器(qi)(qi)更(geng)不(bu)安全，功(gong)率(lv)高(gao)更(geng)加容(rong)(rong)易(yi)(yi)(yi)漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)死(si)人，其實這(zhe)觀念是(shi)不(bu)對的(de)(de)。漏電(dian)(dian)(dian)(dian)(dian)跟(gen)(gen)電(dian)(dian)(dian)(dian)(dian)線質量(liang)有(you)關(guan)系，即(ji)(ji)使是(shi)2.5平方的(de)(de)電(dian)(dian)(dian)(dian)(dian)線，如(ru)果不(bu)符合國家(jia)標準，同(tong)樣(yang)容(rong)(rong)易(yi)(yi)(yi)漏電(dian)(dian)(dian)(dian)(dian)。即(ji)(ji)熱(re)(re)(re)(re)式(shi)熱(re)(re)(re)(re)水(shui)器(qi)(qi)的(de)(de)功(gong)率(lv)更(geng)高(gao)，但不(bu)是(shi)更(geng)容(rong)(rong)易(yi)(yi)(yi)漏電(dian)(dian)(dian)(dian)(dian)，其危險程(cheng)度(du)跟(gen)(gen)家(jia)庭普通電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)一(yi)樣(yang)高(gao)，只要漏電(dian)(dian)(dian)(dian)(dian)，一(yi)樣(yang)把(ba)人電(dian)(dian)(dian)(dian)(dian)死(si)的(de)(de)。人的(de)(de)安全電(dian)(dian)(dian)(dian)(dian)壓承受能力是(shi)36伏(fu)(fu)，高(gao)于36伏(fu)(fu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓都(dou)容(rong)(rong)易(yi)(yi)(yi)電(dian)(dian)(dian)(dian)(dian)死(si)人。另(ling)外即(ji)(ji)熱(re)(re)(re)(re)式(shi)的(de)(de)熱(re)(re)(re)(re)水(shui)器(qi)(qi)在防(fang)電(dian)(dian)(dian)(dian)(dian)方面(mian)也取得了(le)重要的(de)(de)技術突破，比如(ru)隔電(dian)(dian)(dian)(dian)(dian)墻(qiang)、電(dian)(dian)(dian)(dian)(dian)子防(fang)漏電(dian)(dian)(dian)(dian)(dian)保護裝置等(deng)。

4、耗電量

耗電量=功(gong)率×時間，一(yi)千瓦用一(yi)小時就(jiu)是(shi)一(yi)度電。很多(duo)人就(jiu)覺(jue)得儲水(shui)(shui)(shui)(shui)(shui)式(shi)(shi)在功(gong)率上是(shi)小很多(duo)的(de)，用電量肯(ken)定(ding)就(jiu)少很多(duo)。其(qi)實從(cong)能量守恒規(gui)律來看，加熱(re)這么(me)多(duo)水(shui)(shui)(shui)(shui)(shui)到40℃用的(de)電量是(shi)一(yi)樣的(de)，從(cong)這個角度來看，其(qi)實即(ji)(ji)熱(re)式(shi)(shi)與儲水(shui)(shui)(shui)(shui)(shui)式(shi)(shi)耗電差不(bu)多(duo)。但是(shi)儲水(shui)(shui)(shui)(shui)(shui)式(shi)(shi)有一(yi)個大水(shui)(shui)(shui)(shui)(shui)箱，內里(li)儲的(de)都是(shi)熱(re)水(shui)(shui)(shui)(shui)(shui)，如果用不(bu)完，那(nei)一(yi)大桶熱(re)水(shui)(shui)(shui)(shui)(shui)就(jiu)得浪(lang)費不(bu)少電，還要不(bu)斷保溫加熱(re)，所以(yi)總體來說，儲水(shui)(shui)(shui)(shui)(shui)式(shi)(shi)熱(re)水(shui)(shui)(shui)(shui)(shui)器(qi)對電的(de)浪(lang)費不(bu)亞(ya)于即(ji)(ji)熱(re)式(shi)(shi)熱(re)水(shui)(shui)(shui)(shui)(shui)器(qi)。

5、雙模雙核熱水器

有一種(zhong)半儲水(shui)式(shi)(shi)的(de)熱(re)(re)水(shui)器(qi)叫雙模(mo)(mo)雙核熱(re)(re)水(shui)器(qi)，它結合了(le)即(ji)熱(re)(re)式(shi)(shi)與儲水(shui)式(shi)(shi)的(de)優點，即(ji)滿足一些客戶要求快的(de)需求，又避免了(le)大(da)水(shui)箱(xiang)熱(re)(re)水(shui)器(qi)的(de)浪(lang)費。在(zai)這方面走在(zai)全國領(ling)先地位的(de)是奧特朗(lang)開發的(de)預(yu)即(ji)雙模(mo)(mo)機。

6、配置

儲(chu)水式熱(re)水器一般配有混水閥，即(ji)熱(re)式一般不需配混水閥。儲(chu)水式的(de)混水閥可以調節(jie)熱(re)水的(de)熱(re)度，即(ji)熱(re)式通過熱(re)水器本(ben)身(shen)的(de)功率溫度調節(jie)系統控(kong)制出水溫度。
