1、电热水锅炉http://www.jnshengxin.cn/钢制散热器款式、颜色丰富缺点：怕开放式供暖系统。新款钢制暖气采用特殊的厚壁钢管制成，它最大的优点是抗压能力强，不易爆裂，使用寿命可达二三十年。钢制暖气的散热性能也较好，钢制暖气比传统的铸铁暖气体积要小很多，能节约出很大的空间。通常钢质散热器都能保证很长的使用寿命，但它最怕的是老式开放性过路供暖系统，含氧量很高的水会腐蚀散热器内部。
Electric water boiler radiator style, color rich Disadvantages: fear of open heating system. The new steel heating using a special thick-walled steel pipe, its biggest advantage is under pressure, not easy to burst, the service life of up to three decades. Heating steel thermal performance is also better than the traditional steel heating cast iron radiator volume is much smaller, you can save a lot of space. Usually steel radiator can guarantee a long service life,but it is old-fashioned fear of crossing open heating system, high oxygen water will corrode inside the radiator.
2、电热水锅炉铝制暖气散热快，金属铝具有热传导性高、散热快、热效能高、重量轻、自身能耗小等优越的物理性能。由于铝表面遇氧会生成一层致密的三氧化二铝保护层，有效地保护了铝质散热器不被腐蚀，弥补了钢质产品的一大缺陷。铝制散热器单片散热量是铸铁片的3倍，单片水容量只是同等散热铸铁片的1/3，因此在分户供暖的家庭大受欢迎。但铝制散热器不能用于直供加碱的锅炉供热系统，这类供热系统内部循环水的PH值过高，碱性水对散热器寿命有影响。
Electric water boiler aluminum radiator heat dissipation, aluminum has a high thermal conductivity, heat dissipation, high thermal efficiency, light weight, low energy consumption, etc. itself superior physical properties. Since the aluminum surface in case of oxygen will generate a dense protective layer of aluminum oxide, aluminum radiator effectively protected against corrosion, make up a major flaw of steel products. Monolithic aluminum radiator heat is three times the amount of iron sheets, monolithic cast iron cooling water capacity is the same piece of 1/3, and therefore the family household heating popularity. But not for direct supply aluminum radiator alkali boiler heating system,heating system such internal circulating water PH value is too high, alkaline water radiator life affected.
3、电热水锅炉http://www.jnshengxin.cn/纯铜做散热管的散热器，市场上并不多见。多数是铜管外焊接多层铝制散热片，外边再加一层薄金属面板，上边喷涂上各种色彩。由于铜制散热快，所以暖气体积都比较小，市场上最小的暖气高度仅200毫米，安装在室内，非常节省空间。这种铜铝复合散热器多是国产品牌，由于工艺复杂很难工厂化成批生产，因此价格较贵。
Electric water boiler made of pure copper heat pipe radiator on the market are rare. Most of the multilayer copper tubing welded aluminum heat sink, outside plus a layer of thin metal panels, top coating on a variety of colors. Because copper heat quickly, so heating volume are relatively small, smallest on the market heating height of only 200 mm, installed indoors, space-saving. This copper and aluminum composite radiator mostly domestic brands, because the process is complex factory mass production is difficult, and therefore more expensive.
