电热水器镁棒有什么作用?多久要换一次呢?谢谢
1.镁棒的重要性
水在加热后,超过40度可能会产生水垢。镁棒的作用是释放镁离子,软化水质,减少水垢,减缓水垢对金属内胆的腐蚀。

2.镁棒的更换频率
镁棒用一段时间后,就会被消耗掉。如果家里水质差,建议一年更换一次。
有些镁棒非常紧,如果大家想更换镁棒但自己又拧不动,建议大家找专业师傅来更换,通常大品牌像美的、万利达、海尔都会有售后,可以预约上门保养服务。

电热水器 镁棒起什么作用?
镁棒的作用就是减少水箱内胆水垢产生,延长热水器的使用寿命。
现在很多品牌厂家都配置的是长效镁棒,与热水器的寿命同步,所以也无需考虑更换镁棒的问题了。而南方很多地区由于自来水水质较软,不会产生水垢,所以这些地区使用电热水器时,即使是镁棒已经溶解完了,也无需更换镁棒。
热水器镁棒起什么作用?
热水器镁棒用于防止金属内胆腐蚀和软化水质。
家用储水式电热水器为防止水碱、水垢大量附着在储水式电热水器的内胆内,一般采用牺牲阳极的办法,以利用镁棒释放镁离子来减缓水碱、水垢对内胆的腐蚀。
镁棒一旦消耗完,若没有及时更换,就容易造成内胆腐蚀或加热管腐蚀穿孔,从而容易出现漏电危险,造成人身伤害事故。
扩展资料
电热水器的镁棒一般每2年至3年就需更换一次,而部分质量低劣的电热水器的镁棒使用不到半年就会消耗殆尽。但令人担忧的是,一些电热水器厂商并未主动履行告知义务,很多消费者对这一问题并不知情。
众多消费 *** 单位建议,储水式电热水器生产厂家在产品使用说明书或产品外侧醒目处,应粘贴消费提示,提醒消费者该产品需要定期进行检查、更换镁棒;经销商也应主动与生产厂家合作,做好售后服务,定期为消费者提供上门检修。

热水器中镁棒的作用?
镁棒的作用是使内胆绝缘防止腐蚀。
在热水器内胆里面,它和内胆(主要成份是铁)同时与水接触,由于化学原理而形成原电池。
由于内胆里的水不是纯净的水,总含有各种各样的杂质并具有一定的腐蚀性,当水温超过40℃时,就会产生水垢。如果没有阳极镁棒,内胆就被腐蚀。
使用注意:
更好使用经软化处理的自来水。水质的硬度如何,只要看你家中烧水时是否经常结垢(水垢多为钙、镁混合物)便一目了然,易结水垢的水不宜直接供热水器使用(这对燃气热水器更为重要)。
水的硬度高,会造成电加热器周围结成厚厚的垢衣,使加热效率降低,由于热量传递速度减慢,也会危及电加热器自身的寿命。另外,出水管口的垢层不断加厚,会使管的口径减小,甚至堵塞,造成热水器故障。
电热水器里面的镁棒起什么作用?
镁棒又称阳极棒,它的主要成分是镁,放在热水器内胆里面起到保护内胆的作用。
有些电热水器内胆为金属材质(主要成分是铁),胆内的水、水中的化学物质、氧气会与金属内壳发生化学反应,腐蚀金属。若放任这种现象,热水器的寿命将会缩短。
为防止这种状况,在热水器内部放置镁棒,镁的性质活泼可以优先和水中的化学物质反应,代替内壳金属腐蚀。保护热水器内壳,延长使用寿命。
