速熱式熱水器耗電多嗎即熱式熱水器費電嗎

一、即熱式電熱水器的工作原理

即熱式電熱水器是一種利用電來加熱的熱水器，里面主(zhu)要的(de)(de)發熱(re)的(de)(de)是一種(zhong)導熱(re)性比較強的(de)(de)加熱(re)體，熱(re)能把熱(re)量傳遞到水(shui)里，在高功(gong)率下，短短幾(ji)秒中(zhong)，熱(re)量可以讓水(shui)迅(xun)速上(shang)升。

二、即熱式電熱水器的省電原因

1、即熱(re)式電熱(re)水器因為不用提(ti)前預熱(re)，所以(yi)沒有熱(re)能量散失，用時打開，不用時就關閉，節能省電省水。

2、即熱(re)(re)式電(dian)熱(re)(re)水器不(bu)用(yong)長時間預加(jia)熱(re)(re)，也不(bu)需要隨時加(jia)熱(re)(re)保(bao)溫，節省電(dian)能。

3、即熱式(shi)電熱水(shui)器是(shi)水(shui)控機，也(ye)就是(shi)水(shui)開電通，水(shui)關電關，不會(hui)浪費電能。

三、即熱式電熱水器如何實現高功率不耗電

即熱式電熱水(shui)器的額定功率一般(ban)在6千瓦-8千瓦(wa)之間，不(bu)(bu)過因為地區(qu)不(bu)(bu)同，有(you)部分(fen)技術比較好的(de)廠家就能開發出更(geng)低或者(zhe)更(geng)高的(de)的(de)功(gong)(gong)率的(de)。但根據能量守恒定律，功(gong)(gong)率大(da)(da)并不(bu)(bu)等于能耗大(da)(da)，功(gong)(gong)率×時間=能量(電能)。然而一升水從20度升到40度(du)所以的(de)能量是固(gu)定。功率(lv)大(da)，時間(jian)段，功率(lv)小，時間(jian)長。但所耗用的(de)電(dian)能是一樣的(de)。其實即(ji)熱式電(dian)熱水(shui)器(qi)比儲水(shui)式的(de)還(huan)要(yao)省電(dian)些，為(wei)什么(me)呢?因為即熱(re)(re)式(shi)電熱(re)(re)水(shui)(shui)器(qi)(qi)不用(yong)提前預(yu)(yu)熱(re)(re)，所以沒(mei)有預(yu)(yu)熱(re)(re)時(shi)(shi)的熱(re)(re)能量(liang)散失(shi)。用(yong)時(shi)(shi)打(da)開(kai)，不用(yong)就關閉，用(yong)多(duo)(duo)少水(shui)(shui)就放多(duo)(duo)少水(shui)(shui)，所以也沒(mei)有儲水(shui)(shui)式(shi)電熱(re)(re)水(shui)(shui)器(qi)(qi)余水(shui)(shui)熱(re)(re)量(liang)的消(xiao)耗。另(ling)外，即熱(re)(re)式(shi)電熱(re)(re)水(shui)(shui)器(qi)(qi)從(cong)開(kai)機到出水(shui)(shui)溫度達到45℃的加熱時(shi)間只需要幾秒，真正做到了省水省電又省時(shi)。

專家隊對市場上比較好(hao)的儲水式(shi)電(dian)熱水器(qi)做過調查研究，40升(sheng)保溫(wen)效果較好的(de)儲水式電(dian)熱水器，一天24小時一點(dian)熱水不(bu)用，也要耗電1.2度以上(shang)，并且天(tian)氣越冷耗電(dian)量越大。與之(zhi)相(xiang)比，即(ji)熱式(shi)電(dian)熱水器節電(dian)多了，有(you)的儲水式(shi)電(dian)熱水器的保溫(wen)耗電(dian)就足夠供一天(tian)三口之(zhi)家(jia)即(ji)熱式(shi)電(dian)熱水器使用(yong)耗電(dian)。

即熱式熱水器認識誤區有哪些？

1、功率大，不安全？

很(hen)多人認為即熱(re)(re)式電(dian)(dian)(dian)(dian)(dian)熱(re)(re)水器(qi)功率大，不(bu)安(an)(an)全(quan)。實際上(shang)，這(zhe)是一(yi)種誤區。功率大小(xiao)和(he)安(an)(an)全(quan)沒(mei)有(you)(you)關(guan)系，與電(dian)(dian)(dian)(dian)(dian)表(biao)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)線(xian)有(you)(you)關(guan)，只(zhi)要您使用的電(dian)(dian)(dian)(dian)(dian)表(biao)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)線(xian)在允(yun)許范圍內就絕對安(an)(an)全(quan)。安(an)(an)全(quan)跟電(dian)(dian)(dian)(dian)(dian)壓(ya)有(you)(you)直(zhi)接關(guan)系。假如電(dian)(dian)(dian)(dian)(dian)壓(ya)只(zhi)有(you)(you)10伏(fu)，那么即使功率有(you)(you)一(yi)百萬瓦一(yi)千(qian)萬瓦，也(ye)根(gen)本不(bu)會(hui)電(dian)(dian)(dian)(dian)(dian)死人；而如果電(dian)(dian)(dian)(dian)(dian)壓(ya)有(you)(you)一(yi)萬伏(fu)或者上(shang)百萬伏(fu)，那么即使只(zhi)有(you)(you)十(shi)幾瓦，也(ye)可能將人電(dian)(dian)(dian)(dian)(dian)死。家(jia)里幾十(shi)瓦的日光燈電(dian)(dian)(dian)(dian)(dian)壓(ya)是220V，即熱(re)(re)式熱(re)(re)水器(qi)7500W也(ye)是220V，安(an)(an)全(quan)系數是一(yi)樣的。即使很(hen)小(xiao)功率的電(dian)(dian)(dian)(dian)(dian)器(qi)漏電(dian)(dian)(dian)(dian)(dian)也(ye)會(hui)電(dian)(dian)(dian)(dian)(dian)到人。我(wo)們家(jia)里的電(dian)(dian)(dian)(dian)(dian)壓(ya)都(dou)是一(yi)樣的，都(dou)是220伏(fu)，所以不(bu)會(hui)因為哪(na)個電(dian)(dian)(dian)(dian)(dian)器(qi)功率大而更(geng)危險。而且(qie)，安(an)(an)不(bu)安(an)(an)全(quan)主要看(kan)產(chan)品質(zhi)量和(he)安(an)(an)全(quan)保(bao)護裝置，即熱(re)(re)式熱(re)(re)水器(qi)皮(pi)阿諾在這(zhe)方(fang)面(mian)做的非(fei)常好。

首先，專(zhuan)線(xian)連接：即(ji)熱式的(de)安裝(zhuang)都會(hui)要求用(yong)戶(hu)專(zhuan)接4平米電(dian)源線(xian)，并加(jia)裝(zhuang)空(kong)氣開關(guan)（外置漏電(dian)保護裝(zhuang)置）；同(tong)時還加(jia)接保護接地線(xian)。

其次，水(shui)(shui)電(dian)分離(li)加熱(re)：發(fa)(fa)(fa)熱(re)管(guan)和水(shui)(shui)絕對分離(li)，發(fa)(fa)(fa)熱(re)管(guan)的熱(re)量(liang)通過發(fa)(fa)(fa)熱(re)體傳導到(dao)水(shui)(shui)，水(shui)(shui)流并(bing)不直(zhi)接接觸發(fa)(fa)(fa)熱(re)管(guan)。

然(ran)后， 防漏電保(bao)(bao)護裝置(zhi)，瞬時斷電：當(dang)機器內微(wei)電腦監控系(xi)統檢測到(dao)有0.1MA的(de)漏電電流時，熱(re)水器會(hui)在0.1秒(miao)內自動(dong)斷電，并發出危險警(jing)報(bao)，這樣有效(xiao)的(de)避(bi)免觸(chu)電的(de)意外。除此之(zhi)外，聯(lian)創(chuang)熱(re)水器還有雙向(xiang)整體防電墻、全自動(dong)故障自檢裝置(zhi)等十重安(an)全保(bao)(bao)護，最大(da)限度(du)保(bao)(bao)障您的(de)安(an)全。

2、功率大，耗電量大？

其實，即(ji)(ji)熱(re)式熱(re)水(shui)器比桶式的省電，即(ji)(ji)熱(re)式并不(bu)是每次(ci)洗(xi)澡(zao)都是用(yong)(yong)滿功率洗(xi)澡(zao)，以聯創熱(re)水(shui)器舉(ju)例，夏(xia)天(tian)用(yong)(yong)1檔(dang)1500W，春(chun)秋天(tian)用(yong)(yong)2檔(dang)2200W或3檔(dang)3800W，冬天(tian)用(yong)(yong)6檔(dang)7500W。

以(yi)使用熱水器(qi)最多的(de)夏(xia)天(tian)舉例(li)。夏(xia)天(tian)即(ji)熱式熱水器(qi)用1檔功率1500W，耗電(dian)(dian)每小時1.5度(du)電(dian)(dian)，實際洗(xi)澡時間約15分(fen)鐘，實際耗電(dian)(dian)為1.5°/4=0.0.38度(du)電(dian)(dian)；桶式熱水器(qi)需要(yao)預先加熱約45分(fen)鐘，才(cai)可以(yi)制出洗(xi)澡15分(fen)鐘的(de)熱水。以(yi)1500W舉例(li)，45分(fen)鐘相當(dang)于一小時的(de)0.75，1.5°電(dian)(dian)*0.75*0.56元=0.63元；桶式的(de)耗電(dian)(dian)是即(ji)熱式的(de)三倍！！！

以春(chun)秋天舉(ju)例。春(chun)秋天即熱(re)式(shi)熱(re)水器用(yong)2檔或(huo)3檔，三檔功率3800W,洗澡15分鐘(zhong)耗(hao)(hao)(hao)電(dian)(dian)0.95°電(dian)(dian)，電(dian)(dian)費每度(du)0.56元(yuan)，耗(hao)(hao)(hao)電(dian)(dian)費0.532元(yuan)；桶式(shi)熱(re)水器需要預熱(re)1.5小時(shi)，仍(reng)以1500W舉(ju)例，耗(hao)(hao)(hao)電(dian)(dian)1.5*1.5=2.25度(du)電(dian)(dian)，電(dian)(dian)費1.26元(yuan)，仍(reng)是即熱(re)式(shi)熱(re)水器省電(dian)(dian)！！！

以冬(dong)天(tian)舉例。冬(dong)天(tian)皮阿諾即(ji)熱(re)(re)(re)式熱(re)(re)(re)水(shui)器用滿功率7500W加熱(re)(re)(re)。洗澡(zao)時間冬(dong)季約(yue)30分鐘。耗(hao)電(dian)3.75度(du)，電(dian)費2.1元，桶(tong)式1500W需預(yu)熱(re)(re)(re)3小(xiao)時，耗(hao)電(dian)4.5度(du)電(dian)，電(dian)費2.52元，仍然是即(ji)熱(re)(re)(re)式省電(dian)！！！即(ji)使容積小(xiao)的(de)熱(re)(re)(re)水(shui)器如60L加熱(re)(re)(re)2個半小(xiao)時，耗(hao)電(dian)也是3.75度(du)，電(dian)費和即(ji)熱(re)(re)(re)式幾(ji)乎沒有區(qu)別！

從以上對比(bi)(bi)看出，夏季、春秋季即(ji)熱(re)式(shi)明顯比(bi)(bi)桶式(shi)熱(re)水器省電(dian)，冬季略省一(yi)點，總(zong)之，即(ji)熱(re)式(shi)就(jiu)是比(bi)(bi)桶式(shi)省電(dian)！！！

3、功率大，家庭需要改線路？

實際上房(fang)(fang)(fang)屋家庭電路(lu)(lu)設(she)計，2000年前，電路(lu)(lu)設(she)計一般(ban)是(shi)(shi)(shi)：進戶線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)4-6 平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)，插(cha)座線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)2.5 平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)。2000年后(hou)一般(ban)是(shi)(shi)(shi)：進戶線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)6-10 平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)，插(cha)座線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)4 平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)。即(ji)熱(re)式熱(re)水(shui)器(qi)需(xu)要(yao)(yao)用線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)為4 平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)，空氣開關達到40A。也(ye)(ye)就是(shi)(shi)(shi)說(shuo)，2000年以(yi)后(hou)的新房(fang)(fang)(fang)不(bu)(bu)需(xu)要(yao)(yao)改(gai)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)，可以(yi)直接安(an)(an)裝(zhuang)(zhuang)(zhuang)。只有老(lao)房(fang)(fang)(fang)子才(cai)需(xu)要(yao)(yao)改(gai)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)。不(bu)(bu)過(guo)老(lao)房(fang)(fang)(fang)子的線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)也(ye)(ye)老(lao)化的差不(bu)(bu)多了，趁這個(ge)機會換換線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)也(ye)(ye)安(an)(an)全點(dian)。跑(pao)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)麻煩(fan)嗎？不(bu)(bu)麻煩(fan)。在裝(zhuang)(zhuang)(zhuang)修(xiu)時(shi)說(shuo)明(ming)自己(ji)安(an)(an)裝(zhuang)(zhuang)(zhuang)即(ji)熱(re)，跑(pao)4平(ping)米(mi)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)徑(jing)的線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)就可以(yi)了。如果是(shi)(shi)(shi)老(lao)房(fang)(fang)(fang)子，即(ji)熱(re)式熱(re)水(shui)器(qi)安(an)(an)裝(zhuang)(zhuang)(zhuang)人員會幫(bang)你跑(pao)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)。

4、出水溫度不穩定，夏天熱死冬天凍死？

其實，發生這種情況，主要是使用不當造成的。夏天我們只需要使用一檔洗澡，溫度達到人體適宜的42度左右，而且，還可以通過控制進水流量調整溫度，不可能特別燙。至于冬天，滿功率洗澡，溫度同樣在42度左右，水溫完全適宜人體溫度。至于冷死，那是因為冬天環境溫度冷，浴室里要加裝浴霸之類的(de)輔助取暖設施。如果沒(mei)有浴(yu)霸，你用什(shen)么熱(re)水器也一樣冷死。
