1、電熱水鍋爐http://www.nenp.com.cn/鋼制散熱器款式、顏色豐富缺點：怕開放式供暖系統。新款鋼制暖氣采用特殊的厚壁鋼管制成，它最大的優點是抗壓能力強，不易爆裂，使用壽命可達二三十年。鋼制暖氣的散熱性能也較好，鋼制暖氣比傳統的鑄鐵暖氣體積要小很多，能節約出很大的空間。通常鋼質散熱器都能保證很長的使用壽命，但它最怕的是老式開放性過路供暖系統，含氧量很高的水會腐蝕散熱器內部。
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、電熱水鍋爐鋁制暖氣散熱快，金屬鋁具有熱傳導性高、散熱快、熱效能高、重量輕、自身能耗小等優越的物理性能。由于鋁表面遇氧會生成一層致密的三氧化二鋁保護層，有效地保護了鋁質散熱器不被腐蝕，彌補了鋼質產品的一大缺陷。鋁制散熱器單片散熱量是鑄鐵片的3倍，單片水容量只是同等散熱鑄鐵片的1/3，因此在分戶供暖的家庭大受歡迎。但鋁制散熱器不能用于直供加堿的鍋爐供熱系統，這類供熱系統內部循環水的PH值過高，堿性水對散熱器壽命有影響。
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、電熱水鍋爐http://www.nenp.com.cn/純銅做散熱管的散熱器，市場上并不多見。多數是銅管外焊接多層鋁制散熱片，外邊再加一層薄金屬面板，上邊噴涂上各種色彩。由于銅制散熱快，所以暖氣體積都比較小，市場上最小的暖氣高度僅200毫米，安裝在室內，非常節省空間。這種銅鋁復合散熱器多是國產品牌，由于工藝復雜很難工廠化成批生產，因此價格較貴。
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.
