電熱水器是指以電作為能源進行加熱的熱水器。是與燃氣熱水器、太陽能熱水器相并列的三大熱水器之一。電熱水器使用方便，能夠即開即熱，具有省時省電，節能環保、體積小巧、水溫恒定，能持續供應(ying)熱(re)水等諸多優點，受到廣大消費者的(de)歡迎(ying)，不少家庭都選擇使用。電熱水器按加熱功率大小可分為儲水式（又稱容積式或儲熱式）、即熱式、速熱式（又稱半儲水式）三種；按承壓與否，又可區分為敞開式（簡易式）和封閉式（承壓式），按使用途，可分為家用和商用。按加熱方式，可分為磁能、電阻絲、硅管等三種。

對于電(dian)(dian)(dian)(dian)熱(re)水(shui)(shui)(shui)器這種家(jia)庭必備的家(jia)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)器，除非(fei)是(shi)小(xiao)區使(shi)用(yong)(yong)(yong)了(le)集中(zhong)供(gong)熱(re)系統或者鍋(guo)爐、熱(re)泵(beng)等可以(yi)為(wei)多個用(yong)(yong)(yong)戶提(ti)供(gong)熱(re)水(shui)(shui)(shui)的設備使(shi)您不(bu)用(yong)(yong)(yong)另外再購(gou)買之外，購(gou)得一款(kuan)合適的電(dian)(dian)(dian)(dian)熱(re)水(shui)(shui)(shui)器將會給整個家(jia)庭的帶來無盡的舒心和(he)洗(xi)浴快感。但(dan)(dan)是(shi)小(xiao)編(bian)也要(yao)提(ti)醒大(da)家(jia)，電(dian)(dian)(dian)(dian)熱(re)水(shui)(shui)(shui)器在給我們帶來便利的同時(shi)，也存(cun)在著安全(quan)隱患。它看似安全(quan)，但(dan)(dan)由于使(shi)用(yong)(yong)(yong)環境特殊，使(shi)用(yong)(yong)(yong)時(shi)用(yong)(yong)(yong)戶全(quan)身潮濕，如果稍微(wei)泄(xie)露電(dian)(dian)(dian)(dian)流，就可能發生危險，所以(yi)我們需(xu)要(yao)格外重視電(dian)(dian)(dian)(dian)熱(re)水(shui)(shui)(shui)器的使(shi)用(yong)(yong)(yong)安全(quan)以(yi)及相(xiang)關(guan)事項(xiang)。
