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)(qi)帶一個大(da)水桶，通常40升到100升，安裝(zhuang)的時候墻壁需要是承重墻，若裝(zhuang)在浴室還占(zhan)地(di)方，而且影響美觀。即熱(re)式(shi)的熱(re)水器(qi)(qi)就(jiu)(jiu)相對小巧精致，通常就(jiu)(jiu)是17寸(cun)液晶顯示器(qi)(qi)盒(he)子這(zhe)么大(da)，不同(tong)的外形(xing)，安裝(zhuang)方便。

2、功率、電壓

即熱式熱水器功(gong)(gong)率通(tong)常在5500瓦(wa)以(yi)上，廚(chu)房里的(de)(de)小廚(chu)寶(bao)一(yi)般是(shi)5500瓦(wa)，用(yong)(yong)于洗(xi)(xi)手(shou)洗(xi)(xi)菜，而(er)洗(xi)(xi)澡用(yong)(yong)的(de)(de)熱(re)水(shui)器(qi)就(jiu)(jiu)要(yao)(yao)6500瓦(wa)以(yi)上才能達(da)到較好的(de)(de)洗(xi)(xi)浴(yu)效果(guo)。儲水(shui)式(shi)的(de)(de)熱(re)水(shui)器(qi)通(tong)常1000瓦(wa)以(yi)上，比(bi)較多的(de)(de)是(shi)2000瓦(wa)左右。那即(ji)熱(re)式(shi)的(de)(de)熱(re)水(shui)器(qi)功(gong)(gong)率那么高是(shi)不是(shi)對電(dian)線電(dian)壓(ya)(ya)的(de)(de)要(yao)(yao)求(qiu)也(ye)很高呢？其實是(shi)的(de)(de)，6500瓦(wa)到7500瓦(wa)的(de)(de)即(ji)熱(re)式(shi)的(de)(de)熱(re)水(shui)器(qi)要(yao)(yao)求(qiu)4平(ping)方的(de)(de)專(zhuan)(zhuan)線，而(er)8500瓦(wa)的(de)(de)就(jiu)(jiu)要(yao)(yao)求(qiu)6平(ping)方的(de)(de)專(zhuan)(zhuan)線，目前(qian)市面(mian)(mian)上2005年以(yi)后的(de)(de)房子基本都(dou)配有(you)4平(ping)方的(de)(de)專(zhuan)(zhuan)線。如(ru)果(guo)是(shi)5500瓦(wa)的(de)(de)小廚(chu)寶(bao)那就(jiu)(jiu)只需2.5平(ping)方線，基本所(suo)有(you)的(de)(de)家庭電(dian)線都(dou)符合這(zhe)要(yao)(yao)求(qiu)。儲水(shui)式(shi)熱(re)水(shui)器(qi)也(ye)只需2.5平(ping)方線。在電(dian)壓(ya)(ya)要(yao)(yao)求(qiu)方面(mian)(mian)，并不是(shi)功(gong)(gong)率高電(dian)壓(ya)(ya)就(jiu)(jiu)必(bi)須高，功(gong)(gong)率=電(dian)壓(ya)(ya)*電(dian)流，即(ji)熱(re)式(shi)的(de)(de)也(ye)是(shi)用(yong)(yong)220伏。

3、安全性能

目前很多家(jia)庭認為即熱(re)(re)式(shi)的(de)(de)熱(re)(re)水(shui)(shui)器比(bi)(bi)儲水(shui)(shui)式(shi)的(de)(de)熱(re)(re)水(shui)(shui)器更(geng)不(bu)安全，功率高(gao)更(geng)加容(rong)易(yi)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)死(si)人(ren)，其(qi)實這(zhe)觀念是不(bu)對的(de)(de)。漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)跟(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)質量有關系，即使是2.5平方的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)，如果(guo)不(bu)符合國家(jia)標準，同樣容(rong)易(yi)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。即熱(re)(re)式(shi)熱(re)(re)水(shui)(shui)器的(de)(de)功率更(geng)高(gao)，但不(bu)是更(geng)容(rong)易(yi)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，其(qi)危險程(cheng)度跟(gen)家(jia)庭普通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器一樣高(gao)，只要漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一樣把人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)死(si)的(de)(de)。人(ren)的(de)(de)安全電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓承受能力是36伏，高(gao)于36伏的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓都(dou)容(rong)易(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)死(si)人(ren)。另外即熱(re)(re)式(shi)的(de)(de)熱(re)(re)水(shui)(shui)器在(zai)防電(dian)(dian)(dian)(dian)(dian)(dian)(dian)方面也取得(de)了重(zhong)要的(de)(de)技術突破，比(bi)(bi)如隔電(dian)(dian)(dian)(dian)(dian)(dian)(dian)墻、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)防漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)保護裝(zhuang)置等。

4、耗電量

耗電(dian)(dian)(dian)量(liang)(liang)=功率×時間，一(yi)(yi)千(qian)瓦用(yong)(yong)一(yi)(yi)小(xiao)時就是(shi)一(yi)(yi)度電(dian)(dian)(dian)。很(hen)多(duo)(duo)(duo)人(ren)就覺得(de)儲(chu)水(shui)式(shi)(shi)在功率上(shang)是(shi)小(xiao)很(hen)多(duo)(duo)(duo)的(de)，用(yong)(yong)電(dian)(dian)(dian)量(liang)(liang)肯定(ding)就少(shao)很(hen)多(duo)(duo)(duo)。其實(shi)從能量(liang)(liang)守恒規律來看，加熱這么(me)多(duo)(duo)(duo)水(shui)到(dao)40℃用(yong)(yong)的(de)電(dian)(dian)(dian)量(liang)(liang)是(shi)一(yi)(yi)樣(yang)的(de)，從這個角(jiao)度來看，其實(shi)即(ji)熱式(shi)(shi)與儲(chu)水(shui)式(shi)(shi)耗電(dian)(dian)(dian)差(cha)不(bu)多(duo)(duo)(duo)。但是(shi)儲(chu)水(shui)式(shi)(shi)有一(yi)(yi)個大水(shui)箱(xiang)，內(nei)里儲(chu)的(de)都是(shi)熱水(shui)，如(ru)果用(yong)(yong)不(bu)完，那一(yi)(yi)大桶熱水(shui)就得(de)浪費不(bu)少(shao)電(dian)(dian)(dian)，還要不(bu)斷保溫加熱，所(suo)以總(zong)體來說，儲(chu)水(shui)式(shi)(shi)熱水(shui)器對電(dian)(dian)(dian)的(de)浪費不(bu)亞于即(ji)熱式(shi)(shi)熱水(shui)器。

5、雙模雙核熱水器

有(you)一種半儲水(shui)(shui)式(shi)的(de)(de)熱水(shui)(shui)器(qi)(qi)叫雙模雙核熱水(shui)(shui)器(qi)(qi)，它(ta)結合了即熱式(shi)與儲水(shui)(shui)式(shi)的(de)(de)優點，即滿足(zu)一些(xie)客(ke)戶要求(qiu)快的(de)(de)需求(qiu)，又避免(mian)了大(da)水(shui)(shui)箱熱水(shui)(shui)器(qi)(qi)的(de)(de)浪費。在(zai)這方面走在(zai)全國領先地位的(de)(de)是奧特朗開發的(de)(de)預即雙模機。

6、配置

儲水式熱(re)水器一般配(pei)有(you)混水閥，即熱(re)式一般不需配(pei)混水閥。儲水式的混水閥可以調節熱(re)水的熱(re)度，即熱(re)式通過(guo)熱(re)水器本身(shen)的功(gong)率溫度調節系統控制出水溫度。
