许多人担心快速电热水龙头费电量大，其实快速电热水龙头相比较外面畅销的热水器更节能、更省电！以下为快速电热水龙头节能省电的两大原因：一、损耗少：储水式电热水器须较长的时间来预热到较高温度(65-85℃)，边预热边散热，而每人洗澡时间不定，又要用电来保温，很耗电。电热水龙头即开即热，想什么时间用、用多长时间都可以。它的工作温度低(30-55℃左右)，即热即用，不用保温，实际损耗大大减少。二、不浪费：储水式热水器往往用很多电量来加热一大桶水，而热水无法当次使用完，再次使用时又需重新加热，造成很大浪费。电热水龙头只提高所需水的温度，要多少就加热多少，绝不浪费。如以功率及电价计算，2000W的功率，使用一小时耗电量仅为2度，以每度电0.40元计，使用一小时只需0.80元，即每分钟1.3分钱，因是即热式电热水器，家人每次洗碗洗手等开水使用的时间都很短，一天实际的使用次数累计相加大约不到30分钟左右，每天的使用电费仅为0.40元左右，因此非常省电省水。

品牌的比较，一般来说国产品价格便宜，合资品质量稳定，专业化制造商的产品技术和质量比较好，国际销售的品牌实力比较雄厚，技术和制造比较规范，但是价格通常稍高。具体产品来比较的话，需要同一型号、规格才能对比。建议你再多对比些品牌，综合起来，选择性价比最高的，这才是最适合我们的！选择热水器参考以下几点：1.储水式电热水器：优点：干净卫生；安装简单、方便；可多路供水，即可沐浴，也可洗手、洗菜。缺点：带一个容积大的水箱，要承重墙才能装，对于开放式的浴室还影响美观。使用前需要预热，不能连续使用超出额定容量的水，要是家庭人多，洗澡中途还得等。另外，洗完后没用完的热水会慢慢冷却，造成浪费。水温高时，易结垢，污垢清理麻烦，不清又影响发热器寿命。2.燃气热水器：优点：出热水快，只需5秒钟即可；热水量可以不受限制，能多路供水；体积比储水式小。缺点：水压不能太小，否则打不着火；燃烧耗氧气，所以要求浴室通风；废气要确保排放到室外，避免中毒；需装烟道，影响美观。3.即热式电热水器：优点：出热水快，只需3秒钟即可；热水量不受限制，可连续不断供热水；体积小，外形精致；安装、使用方便快捷；需多少热水用多少电，耗能少。缺点：功率高，需预留至少4平方的电线。4.太阳能热水器：优点：安全、节能环保；可多路供水。缺点：安装复杂，如安装不当，会影响住房的外观、质量及城市的市容市貌；维护较麻烦，因太阳能热水器安装在室外，多数在楼顶、房顶，因此相对于电热水器和燃气热水器比较难维护；阴天使用水不够热；易受雷击影响。5.空气能热水器(热泵热水器)：优点：干净安全；环保节能；可多路供水。缺点：体积庞大，占地方；因地方差异，北方地区平均气温，节能效果不明显；一般安装在楼顶或地面，对于中间楼层，安装在阳台影响美观；目前售价高。另外，目前市面上也有一种快速电热水器，既有即热式电热水器的优点又有储水式电热水器的优点。带有两组发热管，一个是储水式的内胆水箱，一个是即热式的内胆。这种热水器叫预即双模双核电热水器。6.预即双模双核电热水器优点：干净安全，节能环保；预热时间比储水式电热水器短，春夏秋不用预热，即开即热，冬天预热8~15分钟；体积小而美观；可多路供水；家庭普通电线即可安装。缺点：功率比储水式电热水器稍高，低于即热式电热水器。以上就是各种功能热水器比较详细的比较，相信对于你购买热水器有一定的帮助！另外需要注意的是：太阳能热水器冬天对进出水管要做好防冻工作,如果水管已冻住,最好不要去动它,因这时的水管很脆,移动时很易折断,只能让它自然溶解.亲的肯定是我最大的动力，满意请点个赞！
