太阳能选购必备指南大全
太阳能、燃气、电热水器经济效益对比表
第一篇
中国家庭热水需求正在发生重大变革，一场以热水替代冷水的大革命正在进行～专家预测，未来3年内中国热水使用总量将基本实现与欧美同步。
与欧美家庭相比我们最大的差距是什么?
生活热水～
近年来我国经济获得了飞速发展，百姓生活水平不断提高，从多项反映文明程度指标如家电、汽车、住房等等来看，中国许多家庭的生活水平已经达到了小康水平，接近甚至超过了欧美国家。但欧美国家人均生活热水用量是国内的十几倍，我们用冷水的地方他们通常使用热水。家庭建设热水系统投资超出彩电、冰箱、洗衣机等家电的总和(见图)。国外家庭屋顶上大面积太阳能集热器, 国外家庭热水专用设备间

持续增长，但热水„„我们一直在漠视热水的使用，更是在漠视我们的健康～
冷、热水洗涤杀菌效果相差5倍
科学研究表明，从洗洁和杀菌效果来看，1倍的热水相当于5倍的冷水。冷水病菌含量高，对健康不利，而热水却能有效杀菌，并预防关节炎、妇女病等疾病的发生。卫生防疫专家呼吁，从有效抑制病菌滋生，增强人体免疫力角度的考虑，生活中应该多用热水。
热水使用状况体现了一个国家或家庭的健康、卫生、文明程度，是生活质量的重要标志。
为什么热水革命常规能源无法担当
虽然燃气、电热水器在中国的推广已近20年，可为什么人们仅仅用于洗澡还不够用呢,
欧美国家人均收入相对较高，能源费用较低，所以热水被广泛应用。而我国能源费用偏高，限制了热水使用的普及。以电费为例，欧美国家约为3-6美分/度，人均费用只占收入的0.1-0.2%左右;中国约为0.5-1元/度，人均费用占收入的1-5%以上。为了节省费用，拥有勤劳淳朴传统美德的中国女性，我们节俭的母亲或妻子舍不得多用热水，她们怕多花钱，宁可以牺牲自己的健康为代价。
另外，国外电热水器规格多为250-1000升，有专门的设备间。而中国的电热水器仅为40-80升，安装在浴室的一角，在热水量、使用安全、后期投入、方便程度上限制了热水的普及。

以使用寿命15年计算，电热水器总费用约为23000元，燃气热水器约为19000元，而大规格优质太阳能热水器仅为4000-10000元左右。换句话说，太阳能热水器4-6年就能收回成本，免费使用近10年(见表一)。太阳能中的热水不用白不用，家庭主妇们会因为担心浪费而更多地使用热水，生活质量明显提高。
与所有家庭大件不一样，太阳能热水器不是消耗品，而是能源生产设备，有无可比拟的投资效益(投资越大，回报越多)。欧美国家早就认识到了这个问题，热水设备投资为10000-30000美元，占房屋投资比例4%-5%还要多。而我们国家的热水设备投资仅为1000-3000元，占房屋投资比例的0.5-1%左右。
太阳能会在很大程度上改变人们传统的生活习惯和热水使用方式，实现国民经济的可持续发展。所以说，无论从经济还是从提高生活质量的角度来讲，太阳能是中国家庭普及热水、与国际接轨、实现真正小康生活的根本解决之道。
现有小规格太阳能热水够用吗
不是所有的太阳能热水器都能满足人们的热水需求，小规格太阳能用户就常有这样的困扰———
阴天能不能用,
冬天能不能用,
隔夜能不能用,
多路供水能不能实现,
人多了够不够用,
女性多了够不够用,
„„
所以说，要达到能用、够用、好用的效果，实现绿色热水文明，科学地选择合适的太阳能热水器是关键。
走出传统用水方式，科学选择热水器
热水的用途日益广泛，人们洗浴的次数由以前的一周一次发展到一天一次，洗浴方式由淋浴发展到盆浴甚至冲浪浴，洗浴目的也由单纯的讲究清洁卫生发展到追求舒适享受。由于以前没有可以参考的选购标准，很多家庭在购买太阳能热水器时没有一步到位，买了性能差的或规格小的不好用、不够用，不得不重新选择或再加1台。由此可见，科学的参考依据对太阳能热水器的选购是至关重要的。它不仅可以帮人们挑选到一步到位、适宜的太阳能热水器，而且会降低购买风险，安全放心。
综合得热当量1—太阳能热水器选购新标准
由于太阳能热水器的选材和工艺技术不同，性能上有很大的差别，所以不能单纯地以容量或真空管的支数为依据来选择太阳能热水器的型号。作为一件使用年限在十几年的热水生产设备，在选择时关注出厂得热当量2，更要关注综合得热当量。
太阳能热水器的出厂得热当量越高，达标寿命3越长，衰减率越低，综合得热当量越高。
影响太阳能热水器出厂得热当量的关键项:真空管的集热性能、保温层的保温性能、内胆性能。
影响太阳能热水器达标寿命和衰减率的关键项:真空度、保温工艺、内胆耐腐性。
真空度:当真空管的真空度降低到一定程度，真空管就几乎不集热了。真空度低或工艺差的真空管出厂3-5年后，像暖水瓶内胆一样时，达标寿命终止。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity. But the sensitivity of the balance are not only associated with these three factors, while carrying heavy loads and balance beam deformation, agate cutters of the fulcrum and the load point of the contact point (that is, agate and knife blades sharp and smooth). So, balance beam made of triangular-ovate, hollowed out in the Middle, triangular-the sensitivity adjustment screw located on the top of a vertical, set two zero point adjusting screw in the horizontal direction, Fulcrum Onyx blade slightly below contains key Onyx blade's "Alice beams" type, and balance beam made of aluminium alloys or titanium alloys light metal alloy. V-shaped, "Alice beams" in order to reduce the impact deformation, knock out heavy and light metal materials to relieve beam measures sensitivity adjustment screw is to use the height to adjust the quality of the nut itself d the length of the horizontal zero-point adjustment screw is the distance from the fulcrum nut quality adjustment nut to adjust the size of the moment change the zero point. Balance of sensitivity General to signs of grid number to measure, that sensitivity = grid/mg but in actually often with "sense volume" to said: sense volume = mg/grid electro-optic balance of sense volume General adjustable into 1mg/grid, and 0.1mg/grid, and 0.01mg/grid, will signs made transparent film, loaded in pointer Shang, then, through optical zoom 10 times"illumination", "welding". 3, electricity lines: (1) electric line, required for overhead installation of resilient rubber sheathed cable or plastic. Adopted at the lane or road protection pipe buried underground, set up signs, connectors must be overhead or located connector box. (2) rubber cable portable power tools, lead length not more than 5 m from the switch box, without joints. (3) use mobile power tools and lighting are soft rubber cord, do not use plastic resin line instead. (4) temporary wiring installations, use a rubber or plastic insulated wires must be knob cables set up, switch set. 4, grounding and zeroing device: (1) grounding electrode available angles, steel of not less than two, depth of not less than 2 m and not less than 2.5 metres in distance between two grounding, grounding resistance is less than 4 ohm. (2) ground (neutral) wires using insulated copper wire, do not use aluminium wire for grounding (neutral) wire joints by welding, crimping a reliable electrical connection. (3) rubber cable core in the "black" or "green/Huang Shuang-color" line as the ground wire. 5, high voltage line protection: (1) in the vicinity of overhead power transmission line construction, erection of bamboo protection frame. (2) in the vicinity of high voltage cable erection Derrick (gantry), scaffolding outside power lines above the water, all safety nets (Booth). 6, handheld or mobile motor: switch box must have leakage protection devices, leakage current 30ma/0.1s, 15mA/0.1s wet job (includes the following equipment: vibration machine, polishing machine, ramming machines, submersible pumps, electric hand Planer, hand drills, grinders, cutters,
保温层:保温层工艺不过关，像黑心棉一样时，热水器的水箱将起不到保温、储能的作用，达标寿命终止。
水箱内胆:内胆锈蚀漏水，热水器将无法工作，达标寿命终止。
附注:
? 综合得热当量:太阳能热水器在达标寿命期内综合获得的热水当量(考虑衰减)。影响综合得热当量的主要因素是:出厂得热当量和达标寿命。
? 出厂得热当量:产品出厂时的性能。
? 达标寿命:产品达到最低使用要求的时间长短。
有的人还活着，他已经死了
有的太阳能还在楼顶，它已经没用了～
一个有心脏病的人，他不仅生活质量低而且寿命短;同样，一个劣质的太阳能热水器，它的出厂得热当量越低，衰减速度越快，达标寿命越短，综合得热当量就越低(综合得热当量=出厂得热当量x达标寿命)。

目前，安装太阳能热水器的家庭越来越多，由于太阳能本身的品质差别悬殊，再加上缺乏使用的技巧，造成部分消费者认为太阳能不好用。为了消除消费者对太阳能的误解，我们针对消费者反映较普遍的问题在此进行解答:
问:太阳能节能环保、经济安全，为什么还有用户说太阳能不好用呢,
答:简单说来，

太阳能好不好用的标准是能否提供足够热、足够量的热水。造成用户说太阳能不好用的原因大体有两个: 一方面是因为消费者选择的是非正规太阳能厂家的产品，品质没有保障，天气不好、冬季不能用，用户在冬季、恶劣天气时的热水需求得不到满足。
另一方面由于在选择太阳能时消费者过于关注价格而选择了小规格的太阳能，而在使用过程中生活方式发生了改变，过去一周一次的洗澡习惯变成了每天一次，而且洗衣服、洗菜等都想用热水，小规格的太阳能无法满足用户的需求。 所以，为了避免以上原因造成的太阳能不好用，消费者在选购时一定要依据按照科学的选购标准，挑选适合自己的太阳能。 问:使用太阳能热水器有技巧吗,
答:要想让家里的太阳能发挥最佳的效果，必要的使用技巧是不可少的。下面这几招您在家里用过吗,如果还没有，不妨一试: 1 、晚上洗澡时，太阳能热水器里的水已经用光，可是人还没冲干净，这时可以上几分钟冷水，利用冷水下沉、热水上浮的原理，将真空管内的热水顶出，就能接着洗澡了。
2 、晚上洗完澡后，热水器水箱里还有一半近 70 ? 的热水，这时是否要上水、上多少水合适要根据天气预报决定上水量。如果
明天是晴天，就上满水;如果是阴雨天，就上 2/3 的水。
3 、由于冬天较冷、热水器上下水管路容易冻结，用户可以通过合理安排上水量及上水时间来进行防冻，当水温达不到洗浴要求时，可启动辅助电加热对太阳能里的温水加热，既省电又能满足需要。皇明集团针对冬季的特点，给太阳能配备了电热带，能够快速融化管路上的冻结水，保证上下水管路畅通。电热带耗电少、升温快、安全可靠，但是不要经常接通电源，天暖时不要忘记拔下来。
都是太阳能，为什么差别这么大,
家住县城的小张是个整天乐呵呵的小伙子，这两天他却为买太阳能热水器的事犯了愁:当地二十多个牌子的太阳能都说自己产品好，问家里安了太阳能的同事吧，又都说“用着还可以”。这样一来，能不让小张为难吗,
其实，对太阳能存在这种困惑人还真不少，那么太阳能到底是不是都差不多呢,实际上，不同的太阳能品质并不一样，使用效果更是大不一样。
太阳能“出身”不一样，品质自然不一样
太阳能“出身”的高低取决于生产厂家，大品牌厂家生产的太阳能身份尊贵、性能稳定、品质卓越，非正规厂家生产的太阳能地位平庸，而且质量没有保证、使用寿命低。为什么大品牌厂家能保证产品卓越的品质呢,
对任何一个行业来说，大品牌企业的一举一动都会给整个行业带来巨大的影响，所以，大品牌企业不仅要输出优质产品，更要在一定程度上引导整个行业向前发展。所以，对产品的品质进行高标准的要求对大品牌企业来讲是顺理成章的事。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity. But the sensitivity of the balance are not only associated with these three factors, while carrying heavy loads and balance beam deformation, agate cutters of the fulcrum and the load point of the contact point (that is, agate and knife blades sharp and smooth). So, balance beam made of triangular-ovate, hollowed out in the Middle, triangular-the sensitivity adjustment screw located on the top of a vertical, set two zero point adjusting screw in the horizontal direction, Fulcrum Onyx blade slightly below contains key Onyx blade's "Alice beams" type, and balance beam made of aluminium alloys or titanium alloys light metal alloy.

(4) temporary wiring installations, use a rubber or plastic insulated wires must be knob cables set up, switch set. 4, grounding and zeroing device: (1) grounding electrode available angles, steel of not less than two, depth of not less than 2 m and not less than 2.5 metres in distance between two grounding, grounding resistance is less than 4 ohm. (2) ground (neutral) wires using insulated copper wire, do not use aluminium wire for grounding (neutral) wire joints by welding, crimping a reliable electrical connection. (3) rubber cable core in the "black" or "green/Huang Shuang-color" line as the ground wire. 5, high voltage line protection: (1) in the vicinity of overhead power transmission line construction, erection of bamboo protection frame.

与之相对的是非正规的生产厂家，受规模、资金、工艺等多种因素的影响不能保证产品的质量，更有甚者，纯粹是受利益的驱使，以混入市场赚黑心钱为目的，就更不会把产品质量放在首位了。
下面，让我们具体来看一个大品牌企业是怎样保证产品卓越品质的:
选材要过关，更要最好 生产太阳能热水器的主要原材料是真空管、保温材吸收率料、内胆。原材料的选择是保证产品品质的第一要素，大品牌企业在进行原材料选择时，不仅要求过关，而且会选取最优的品种。
仅以内胆为例，品牌企业生产的太阳能采用进口 SUS304 不锈钢，耐腐蚀、耐高温，厚达 0.6mm ，使用寿命长。与之相对劣质内胆含抗腐蚀元素少甚至没有，厚度仅为 0.25 mm 左右，不耐高温易渗漏，使用寿命短。据相关测试数据表明，优质内胆比劣质内胆成本高 2-4 倍，耐腐蚀寿命高 2-4 倍。
工艺要达标，更要领先 要生产出一流的太阳能，就要掌握行业的领先技术。太阳能真空管的镀膜技术是决定太阳能集热效果的关键因素，目前最好的镀膜技术是皇明集团应用的专利干涉镀膜技术，这项技术的发明人是被称为“世界镀膜王”的章其初博士。而一般厂家只能采用渐变膜技术，集热效果与前者相差悬殊。
服务要长久，更要专业 作为家庭大件耐用品，售后服务是消费者所关心的问题。品牌企业有实力、有能力提供长久的服务、组织专业化的服务队伍，消费者可以放心选购。劣质厂家连产品质量都不能保证，又何谈及时高效的售后服务呢, 由此可见，品牌太阳能和劣质太阳能的差别何止几倍,
太阳能品质不一样，使用效果自然不一样
说太阳能好不好用，至少要考虑三方面的因素:
第一 , 刚买来时好用不一定长时间好用。一般太阳能在刚出厂时使用效果还可以，但由于衰减快寿命短，所以劣质太阳能两三年后就不能用了。而优质太阳能不但出厂时好用，而且达标寿命长，可以好用十几年。
第二，晴天时好用，不一定阴天、冬天好用。由于集热能力不一样，劣质太阳能在晴天时用着还可以，但到阴雨天、冬天就不能用了。而综合得热当量值高的太阳能集热效果好，在阴雨天、冬天也能照常出热水，一年之中较一般太阳能可以多用几十天的热水。
第三，不单要看现在还要看将来。劣质太阳能在过去家里人口少的时候，还可以满足每周一次的淋浴，但现在人口多了，而且偶尔有客人入住，这时热水就不够用了。同时，过去每周洗一次澡就可以了，现在生活方式发生了改变，要每天洗一次澡就不够用。 高品质的太阳能则不但可以实现多路供水，满足多方位的热水需求，还可实现盆浴。足量的热水可以用来洗衣服、洗菜、拖地板等。不单现在够用，而且三五年都不会落伍。
原来，太阳能因其品质高低而各不相同，只有高品质的太阳能热水器才能提供高品质的洗浴效果，也只有高品质的太阳能你会选择太阳能热水器吗,
随着人们环保节能意识的增强，安装太阳能热水器的家庭越来越多。为保证正常的使用，消费者在选购太阳能热水器时，以下问题应该重视:
1、买太阳能热水器干什么用,
(1) 洗碗、洗菜想不想用热水,
(2) 洗手、洗衣服想不想用热水, that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity. But the sensitivity of the balance are not only associated with these three factors, while carrying heavy loads and balance beam deformation, agate cutters of the fulcrum and the load point of the contact point (that is, agate and knife blades sharp and smooth). So, balance beam made of triangular-ovate, hollowed out in the Middle, triangular-the sensitivity adjustment screw located on the top of a vertical, set two zero point adjusting screw in the horizontal direction, Fulcrum Onyx blade slightly below contains key Onyx blade's "Alice beams" type, and balance beam made of aluminium alloys or titanium alloys light metal alloy. V-shaped, "Alice beams" in order to reduce the impact deformation, knock out heavy and light metal materials to relieve beam measures sensitivity adjustment screw is to use the height to adjust the quality of the nut itself d the length of the horizontal zero-point adjustment screw is the distance from the fulcrum nut quality adjustment nut to adjust the size of the moment change the zero point. Balance of sensitivity General to signs of grid number to measure, that sensitivity = grid/mg but in actually often with "sense volume" to said: sense volume = mg/grid electro-optic balance of sense volume General adjustable into 1mg/grid, and 0.1mg/grid, and 0.01mg/grid, will signs made transparent film, loaded in pointer Shang, then, through optical zoom 10 times"illumination", "welding". 3, electricity lines: (1) electric line, required for overhead installation of resilient rubber sheathed cable or plastic. Adopted at the lane or road protection pipe buried underground, set up signs, connectors must be overhead or located connector box. (2) rubber cable portable power tools, lead length not more than 5 m from the switch box, without joints. (3) use mobile power tools and lighting are soft rubber cord, do not use plastic resin line instead. (4) temporary wiring installations, use a rubber or plastic insulated wires must be knob cables set up, switch set. 4, grounding and zeroing device: (1) grounding electrode available angles, steel of not less than two, depth of not less than 2 m and not less than 2.5 metres in distance between two grounding, grounding resistance is less than 4 ohm. (2) ground (neutral) wires using insulated copper wire, do not use aluminium wire for grounding (neutral) wire joints by welding, crimping a reliable electrical connection. (3) rubber cable core in the "black" or "green/Huang Shuang-color" line as the ground wire. 5, high voltage line protection: (1) in the vicinity of overhead power transmission line construction, erection of bamboo protection frame. (2) in the vicinity of high voltage cable erection Derrick (gantry), scaffolding outside power lines above the water, all safety nets (Booth). 6, handheld or mobile motor: switch box must have leakage protection devices, leakage current 30ma/0.1s, 15mA/0.1s wet job (includes the following equipment: vibration machine, polishing machine, ramming machines, submersible pumps, electric hand Planer, hand drills, grinders, cutters,
(3) 洗抹布、拖地(洗拖布)想不想用热水,
(4) 考虑过用热水洗车吗,
2、为家里的老人考虑盆浴了吗,
老人洗淋浴站时间长了容易疲劳、滑倒;淋浴时热气少、温度低，老人容易感冒;淋浴不如盆浴解乏、舒坦。所以，出于安全、健康的考虑，应该让家里的老人多洗盆浴为好。
3、家里共有几个水龙头,每个水龙头是不是都想要有热水,
太阳能热水器能够实现多路供水，让每个水龙头都有热水可用，家人使用热水才更方便。
4、冬天想不想用热水,
基于健康的考虑越来越多的人开始选择在家里洗澡，洗澡时先放一些热水，浴室水温就会升高，就可以在家洗澡了。即使冬天不在家里洗澡，洗手、洗碗、洗菜、洗衣服等还是要在家里。
5、太阳不好时想不想用热水,
太阳不好时，太阳能热水器如果有大的得热量，太阳能热水器的水箱里有热水的储存就不用愁了，一样可以用热水。 6、隔夜想不想用热水,
如果太阳能热水器有较高的保温效果，隔夜的水也还可以保持较高的温度，不影响第二天的使用。
7、是想买个一步到位的，还是过几年就调换的,是想买个能用三五年的，还是能用十几年的,
据调查，未来三年我国人均生活热水用量将与欧美发达国家同步，好的太阳能热水器可以将热水需求一步到位，保证三五年不会
落伍。
好的太阳能热水器，在冬天晴好天气时一天就能达到洗澡温度42度以上，有的就达不到; 寿命差别也很大，有的太阳能热水器能用3年、5年、8年，而好的太阳能热水器可以使用十几年，这样算起来生产的热水总量就差别4、5倍之多。
8、是买个太阳不好时能生产35度热水的还是80度热水的,
如果太阳能有较高的得热量，在太阳不好时，也能提供足够热的水。
9、200升60度、70度、80度的热水相当于40度热水多少升,
由下表可知:如果太阳能热水器具有超大得热量、水温高、兑冷水更多，得出40度达到洗澡温度的热水量就更大。

热水器才能创造出高品质的热水生活～
居家过日子，谁家也离不开洗洗涮涮。其实生活热水不仅可以清洁卫生，而且具有不可低估的健身和美容之功效。 美丽肌肤洗出来
洗澡，养生学的术语叫做浴身。据考证，殷商甲骨文中就有“沐浴”一词，“沐”指洗头发，“浴”指澡身。中国美容科技专家团高级研究员张湖德教授指出:热水沐浴的意义远远不止清洁和卫生，它还有健身和美容的功效。
张湖德认为，热水洗澡不但可以消除疲劳，而且可以减肥。因为构成人体的成分中水占的比重很大，在60%左右。这种水分能很容易地通过洗澡变为汗水而排出体外，从而使体重减轻。
热水洗澡可以使皮肤水灵。人们在形容一个姑娘美的时候，往往会说这个姑娘真水灵。世上绝对没有汗臭的美人、满身污垢的佳丽。皮肤之所以水灵，是因为热水洗澡可以促进新陈代谢，加速激素分泌，使健康的皮肤变美。尤其是女性在洗澡时，激素会顺畅地从血液中输送到皮肤部位，因而肌肤白皙，皮下脂肪均匀，肌肤变得水灵。
家庭“液体小药箱”
一家大小，免不了有个头疼脑热的，一些常用药就成了许多家庭的必备品。其实，生活热水对于缓解、治疗一些常见病有着不小的功效，所以有人称热水是家里的“液体小药箱”。
食欲不佳时:用热水喷头刺激胃部，待身体暖和后，再用20?左右的水在胸口周边转圈喷水，每冲五秒就休息一分钟，如此重复五六次。
患感冒而又不愿吃药时:可用热水浸脚治疗。将双脚泡在一大盆热水里，水以能够浸到踝骨为宜。在浸泡过程中，要不断地添加热水，浸泡至脚面发红或身上微微出汗为止，在水中放些盐、醋，则疗效更佳。
风湿性腰部寒痛时:可以用热水蒸气熏烘的方法，使腰际处受暖而除去寒湿。即让患者平躺在两张椅子上，将后腰部的衣服撩起，取电热杯放入热水，接通电源，放在患者腰下，使不断产生的热蒸气熏烘腰际。长期坚持，可散寒止痛。 目前，我国普通百姓解决生活热水的途径主要有使用电热水器、燃气热水器和太阳能热水器三种。21世纪我国面临着经济的可持续发展与节能环保的双重课题，用可再生清洁能源解决全部或部分家用热水，节能环保意义重大，推广普及太阳能热水器是解决百姓生活热水的唯一有效途径。
中国目前有12.9亿人口，3.5亿个家庭，按较低标准计算，每日每户供应60?热水100升，从15?,60?共需4.5×106卡热量，解决途径如下:
电热水器:每日每户供应60?热水100升，按现行平均电价计算，每户用于热水供应的电费约为1140元/年，普通百姓难以承担;电厂，尤其是火电厂，会严重污染环境。
结论:用电产生生活热水，需要极大投资，若用10年解决25,的家庭用电产生生活用热水，每年需新增2000万kw容量，相当于长江三峡工程一期总容量的10倍以上。
燃气热水器:使用中产生CO、CO2等废气，污染环境;直排式燃气热水器，在室内通风不好的情况下有一定的危险性;每户每日60?热水100升，月耗燃气约30m3，费用约15元;输送管道投资极大。

结论:投资极大，使用费用高，资源不足，县级城市及广大农村等基本不可能实现。
太阳能热水器:相对于人类发展短暂的寿命而言，太阳能可谓取之不尽、用之不竭，无需开采、运输，无运行费用，不需政府投资。 目前，生活热水用量成为小康家庭一项新的指标，人们对生活热水的需求量日益增大。普通小规格太阳能热水器已经难以满足人们的热水需求，能提供大量热水、高质量的“家庭热水中心”正成为人们的首选。
结论:用大规格、高性能的太阳能解决中国家庭热水需求是最有希望、最有效可行的途径，太阳能光,热应用市场前景广阔，推广使用太阳能热利用产品利国利民、前景光明。 (原载太阳能信息网)
据有关资料显示，近十年来，我国人均住房面积增长了30%，住房投资增加了10倍，家用电器更新了四代，居民生活水平大幅度提高，某些指标已经接近甚至超过了欧美发达国家。但是，由于长期使用冷水，导致我国部分居民健康指数偏低，有关专家呼吁，有健康才有真正的小康，热水用量应该成为小康家庭的一项新指标。
受传统观念的影响和现有热水提供方式的限制，我国居民对生活热水的重视程度普遍较低。据相关调查结果表明，我国生活热水使用情况落后欧美发达国家十几倍。家庭生活中冷热水的使用比例欧美发达国家是1:9，中国是9:1;欧美国家冷水只做饮用、冲厕所用，其他方面都用热水，而中国热水只做饮用、洗澡用，其他方面都用冷水;洗浴用水标准日本约为150升/人次，中国是40升/人次;国外电热水器规格多为250-1000升，有专门的设备间，而中国的电热水器仅为40-80升，安装在浴室的一角，在热水量、使用安全、后期投入、方便程度上限制了热水的普及„„长期大量地使用冷水，很大程度上影响了我国居民的健康水平。据《中国妇女报》对我国家庭热水使用情况进行的调查结果显示，目前我国80%的家庭妇女患有不同程度的妇科病、风湿病、关节炎，其直接诱因就是冷水在生活中的长期使用。
专家指出，就清洁和杀菌效果而言，热水的杀菌效果是冷水的5倍，用热水清洁能达到更有效的杀菌效果。从有效抑制病菌滋生，增强人体免疫力角度的考虑，生活中应该多用热水。热水的充分利用，可以降低家庭主妇患关节炎等疾病的机率，减少家人接触细菌的机会，创造清洁卫生的居家环境。
小康生活是多项指标综合评价的结果，健康状况是不容忽视的一项重要内容。热水使用状况体现了一个国家或家庭的健康、卫生、文明程度，是生活质量的重要标志。将生活热水用量作为小康生活的新的指标，有助于改善居民生活质量，从而实现真正意义上的小康。
中国家庭热水需求正在发生重大变革，一场以热水替代冷水的大革命正在进行～专家预测，未来3年内中国热水使用总量将基本实现与欧美同步。
与欧美家庭相比我们最大的差距是什么?
生活热水～
近年来我国经济获得了飞速发展，百姓生活水平不断提高，从多项反映文明程度指标如家电、汽车、住房等等来看，中国许多家庭的生活水平已经达到了小康水平，接近甚至超过了欧美国家。但欧美国家人均生活热水用量是国内的十几倍，我们用冷水的地方他们通常使用热水。家庭建设热水系统投资超出彩电、冰箱、洗衣机等家电的总和(见图)。

让我们来看一组对比数据:
冷、热水使用比例--欧美国家是1:9，中国是9:1;
冷、热水使用范围--欧美国家冷水只做饮用、冲厕所用，其他方面都用热水，而中国热水只做饮用、洗澡用; 洗浴用水标准--日本约为150升/人次，中国是40升/人次。
近十年来，我国的人均住房面积增长了30%，住房投资增加了10倍，家用电器更新了4代，私家车以每年两位数的增长率在持续增长，但热水„„我们一直在漠视热水的使用，更是在漠视我们的健康～
冷、热水洗涤杀菌效果相差5倍
科学研究表明，从洗洁和杀菌效果来看，1倍的热水相当于5倍的冷水。冷水病菌含量高，对健康不利，而热水却能有效杀菌，并预防关节炎、妇女病等疾病的发生。卫生防疫专家呼吁，从有效抑制病菌滋生，增强人体免疫力角度的考虑，生活中应该多用热水。
热水使用状况体现了一个国家或家庭的健康、卫生、文明程度，是生活质量的重要标志。
为什么热水革命常规能源无法担当
虽然燃气、电热水器在中国的推广已近20年，可为什么人们仅仅用于洗澡还不够用呢,
欧美国家人均收入相对较高，能源费用较低，所以热水被广泛应用。而我国能源费用偏高，限制了热水使用的普及。以电费为例，欧美国家约为3-6美分/度，人均费用只占收入的0.1-0.2%左右;中国约为0.5-1元/度，人均费用占收入的1-5%以上。为了节省
费用，拥有勤劳淳朴传统美德的中国女性，我们节俭的母亲或妻子舍不得多用热水，她们怕多花钱，宁可以牺牲自己的健康为代价。
另外，国外电热水器规格多为250-1000升，有专门的设备间。而中国的电热水器仅为40-80升，安装在浴室的一角，在热水量、使用安全、后期投入、方便程度上限制了热水的普及。
太阳能热水不用白不用
太阳能不占用室内空间，既可单台使用，亦可组建热水系统，满足不同的热水需求，为家庭提供了更便捷、更充裕、更完善的热水解决方案。
以使用寿命15年计算，电热水器总费用约为23000元，燃气热水器约为19000元，而大规格优质太阳能热水器仅为4000-10000元左右。换句话说，太阳能热水器4-6年就能收回成本，免费使用近10年(见表一)。太阳能中的热水不用白不用，家庭主妇们会因为担心浪费而更多地使用热水，生活质量明显提高。
与所有家庭大件不一样，太阳能热水器不是消耗品，而是能源生产设备，有无可比拟的投资效益(投资越大，回报越多)。欧美国家早就认识到了这个问题，热水设备投资为10000-30000美元，占房屋投资比例4%-5%还要多。而我们国家的热水设备投资仅为1000-3000元，占房屋投资比例的0.5-1%左右。
太阳能会在很大程度上改变人们传统的生活习惯和热水使用方式，实现国民经济的可持续发展。所以说，无论从经济还是从提高生活质量的角度来讲，太阳能是中国家庭普及热水、与国际接轨、实现真正小康生活的根本解决之道。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity.

现有小规格太阳能热水够用吗
不是所有的太阳能热水器都能满足人们的热水需求，小规格太阳能用户就常有这样的困扰———
阴天能不能用,
冬天能不能用,
隔夜能不能用,
多路供水能不能实现,
人多了够不够用,
女性多了够不够用,
„„
所以说，要达到能用、够用、好用的效果，实现绿色热水文明，科学地选择合适的太阳能热水器是关键。 走出传统用水方式，科学选择热水器
热水的用途日益广泛，人们洗浴的次数由以前的一周一次发展到一天一次，洗浴方式由淋浴发展到盆浴甚至冲浪浴，洗浴目的也由单纯的讲究清洁卫生发展到追求舒适享受。由于以前没有可以参考的选购标准，很多家庭在购买太阳能热水器时没有一步到位，买了性能差的或规格小的不好用、不够用，不得不重新选择或再加1台。由此可见，科学的参考依据对太阳能热水器的选购是至关重要的。它不仅可以帮人们挑选到一步到位、适宜的太阳能热水器，而且会降低购买风险，安全放心。
综合得热当量1—太阳能热水器选购新标准
由于太阳能热水器的选材和工艺技术不同，性能上有很大的差别，所以不能单纯地以容量或真空管的支数为依据来选择太阳能热水器的型号。作为一件使用年限在十几年的热水生产设备，在选择时关注出厂得热当量2，更要关注综合得热当量。 太阳能热水器的出厂得热当量越高，达标寿命3越长，衰减率越低，综合得热当量越高。
影响太阳能热水器出厂得热当量的关键项:真空管的集热性能、保温层的保温性能、内胆性能。
影响太阳能热水器达标寿命和衰减率的关键项:真空度、保温工艺、内胆耐腐性。
真空度:当真空管的真空度降低到一定程度，真空管就几乎不集热了。真空度低或工艺差的真空管出厂3-5年后，像暖水瓶内胆一样时，达标寿命终止。
保温层:保温层工艺不过关，像黑心棉一样时，热水器的水箱将起不到保温、储能的作用，达标寿命终止。 水箱内胆:内胆锈蚀漏水，热水器将无法工作，达标寿命终止。
附注:
? 综合得热当量:太阳能热水器在达标寿命期内综合获得的热水当量(考虑衰减)。影响综合得热当量的主要因素是:出厂得热当量和达标寿命。
? 出厂得热当量:产品出厂时的性能。
? 达标寿命:产品达到最低使用要求的时间长短。

初级标准--需求热水当量约为
在关于太阳能热水器的常识里，有一些似是而非的问题，如果不弄清的话，很容易走入误区，下面我们举几个常见的例子。
水箱越大越好吗,
在一定光照条件下，一支真空管在单位时间内能加热多少水是一定的。因此，并非水箱越大越好。假设真空管的采热质量相同，同样的晴好天气，按基础水温15 度来算，20支真空管可以把150升的水加热到70度，160升的水则仅可以加热到66度，170升的水加热到63度，依次类推。洗浴温度通常在40度时是合适的，也就是说，最终可为我们使用的热水量是相同的。而在一些日照较少的月份，例如只有4小时日照，20支真空管加热150升水达到洗浴温度，容量过大的就不一定行。皇明太阳能的真空管支数与水箱容量有着严格的科学配比。
单数双数有区别吗,
市场上有的太阳能热水器真空管支数是单数，而皇明产品大部分是双数，单数与双数并没有本质上的区别。皇明产品都是经过充分的优化设计，真空管支数与水箱容量配比合理，充分提高了热水器热效率和用户对热水的需要。
夏天不用热水洗澡浪费,
有人说买了热水器后冬天洗澡倒是挺合算，可夏天用不了多少热水，买了不是浪费吗,实际上，天热不用热水洗澡对大部分人而言不仅仅是习惯问题，也是考虑节约(出差住宾馆不用热水的人很少)。皇明太阳能家庭热水中心能提供多路供水，除了盆浴、淋浴外，还可用于温水洗衣、洗漱、厨房洗菜等其它用途，不用电不用气，就象自来水一样。并且太阳能热水器的使用寿命与使用频率也没有直接关系，所以，夏天太阳能热水器用处更多。

高楼层住户不好用太阳能热水器,
7—8层高的的高楼层住户使用太阳能热水器时效果丝毫不差，因为皇明热水器的上、下水管内径为10毫米，可顺排气管或烟道顺下，不影响通风和排烟。同时，水管内壁光滑无接头，阻力小，上、下水量并不比普通自来水管少，只是得到热水前需多放一些冷水(大约每层多200毫升，折合1/10脸盆水)。

太阳能热水器综合得热当量参考表
生活中使用热水，是人们司空见惯的事情。但受积习和旧观念的影响，在热水使用及热水器购买中还存在着六大误区: 误区一:“买热水器只是用来洗澡的”。其实热水应该成为生活用水的主角，不单是洗澡，更可以用来洗菜(去除农药残留)、洗碗(高效洗净油腻)、洗衣(节省并充分利用洗衣粉)、拖地(有效洁净污渍)、洗车(保护漆面)等等。这不仅是健康卫生的需要，更是生活品质提高和人类文明进步的象征。
误区二:“用热水比用冷水多花钱”。从洗净和杀菌效果来看，一倍热水抵过五倍的冷水，反而是节省了用水，而且更能促进健康。
误区三:“用热水要现加热、要等”。皇明“冬冠180”大规格、大热量，具有热水充沛、保温时间长、光电完美结合的优势和特点，让你想洗就洗，保证热水随时用随时有，不用再等待。
误区四:“多用热水多花加热钱”。太阳能热水器，通过利用免费而充足的太阳能资源，让您一次投资，长期受益，加热热水不要钱，不用白不用。不用热水不但是对您自身及家人健康的忽视，更是对太阳能资源的极大浪费。
误区五，“太阳能冬天不能用，不好用”。其实皇明“冬冠180”冬天一样好用，因为它配备了国际领先技术的三高真空管，严寒条件下照样出热水。
误区六:“太阳能买小的经济些”。不要以为就象是25吋的彩电，比起29吋就是小点，凑和能看也就行了。其实大太阳能和小太阳能的区别就象彩电和黑白电视机，有着本质的区别。大的就能让你时时用热水，人人用热水，事事用热水，长远看来更划算。 太阳能中央热水系统即采用太阳能集热，配以辅助能源组成的热水系统。该系统具有供热水量大，性能稳定、安全方便、节能环保等特点，可替换锅炉等传统大型供热系统提供集体用热水，使用户一次投资长期受益，广泛应用于宾馆、酒店、工厂宿舍、公共浴室、学校、医院、部队等企事业单位。
下面以皇明太阳能为例说一下太阳能中央热水系统的性能特点:

由此我们可以看出，这四种方案在家庭热水供应方面，基本都能满足要求，但是从使用、经济、环保、安全等方面综合比较而言，有明显的差别。
电热水器系统舒适度、安全性能、环保性能、安装施工都比较好，但运行费用过高。
燃气热水器系统运行费用相对较低，但舒适程度一般，安全性和使用寿命不高。
单纯太阳能热水器运行费用最省，但阴雨天和水量变化大的情况，热水不能保证。
太阳能加电辅助热水系统，综合优点明显，其舒适、经济、环保、安全、可靠、寿命长，应该是首选。太阳能(电辅助)热水系统方案，以人为本体现生态、节能、环保，此方案无疑是家庭生活热水系统的理想方案。
太阳能热水器在使用过程中，如果巧妙地安排、利用上水时间和上水量，会起到事半功倍的效果。刚刚开始使用的用户可能不太清楚，时间长了，慢慢就会摸索出经验和规律。
1、洗澡时，如果太阳能热水器里的水已经用光，而人还没有冲洗干净，这时可以上几分钟冷水，利用冷水下沉、热水上浮的原理，将真空管内的热水顶出，就能接着洗澡了。
2、利用1的原理，如果洗完澡后，太阳能热水器里还有一点热水，这时上几分钟冷水，所得的热水可以多洗一个人。 3、根据天气预报决定上水量，可以获得比较满意的水温。如果明天晴天，可把水上满;如果阴天或多云，则上半箱水;有雨，保留原有的水不上冷水。
4、晚上洗完澡后，如果热水器水箱里还有一半近70?的热水，为了防止热散失过大(水量越少，热散失越快)，也要根据水温天气预报决定上水量。明天晴天，上满水;阴雨天，上2/3的水。
5、冷热水调节:热水器的水温调节步骤:先打开冷水阀，适当调节冷水流量，再打开热水阀调节，直到得到所需的洗浴温度。另外，可以凭经验根据天气情况确定冷水量，注意喷头不要朝向人体，避免烫伤。
6、抗风
措施
《全国民用建筑工程设计技术措施》规划•建筑•景观全国民用建筑工程设计技术措施》规划•建筑•景观软件质量保证措施下载工地伤害及预防措施下载关于贯彻落实的具体措施
:由于太阳能热水器的零部件连接可靠，抗风性能主要取决于它的安装固定方式。
7、如何延长寿命:为了延长太阳能热水器的使用寿命，用户在使用过程中应注意:热水器安装固定好了以后，非专业人员不要轻易挪动、卸装，以免损坏关键元件;热水器周围不应放杂物，以消除撞击真空管的隐患;定期检查排气孔，保证畅通，以免胀坏或抽瘪水箱;定期清洗真空管时，注意不要碰坏真空管下端的尖端部位;有辅助电加热装置的太阳能热水器应特别注意上水，防止无水干烧。

(1)气温不太低(5-7?)的情况下，当天晚上用水后，如水箱内还有热水，宜立即将太阳能热水器上满水，降低水箱内水温及当夜热损失，充分利用热能;如气温较低，宜明天早晨上水，以利于热水器出水口处管路防冻。
(2)收听天气预报，如当天日光不强，可根据实际需要上半箱水，或多半箱水。如果用水量大，可考虑启动太阳能热水器中的电加热或将太阳能热水器里的水放入电热水器中稍稍加热即可。
天天洗澡好不好,人每天都会有新陈代谢的产物，所以可以天天洗澡，但头发不宜天天洗，3天时间最合适，以免头发因缺乏油脂而变干变黄。
洗澡时水温在多少度最合适,不是水温越热越有杀菌功效。水温过热蒸气太强，皮肤过于发红发烫反而不好。常用过热的水洗脸洗澡，还会导致皮肤老化。一般水温控制在40度到50度最佳。
搓洗的方向应该是顺毛孔方向还是逆毛孔,正确的方法是按顺毛孔方向搓洗，因为洗浴时毛孔都是张开的，顺毛孔清洗，秽物不会从毛孔进入而污染皮肤。
洗澡用劲搓洗好吗,有人喜欢洗澡时用劲搓，这种做法是不科学的。在人的身体表面，有一层覆盖全身的死皮肤，厚度不到0.1毫米，但作用却十分重要。它每时每刻都在有效地阻挡着致病的细菌、真菌以及危害健康的射线入侵，是保护人体健康的一道天
然防线。这些死皮的更换速度很慢，而且因身体部位的不同而异，更换最快的是肘部，需要10天，上臂内侧则需100天。洗澡使劲搓洗，就会破坏了这层死皮肤，而新的死皮肤不会很快产生出来，这样就等于自动撤销了这道保护健康的天然防线。 洗浴时应该先洗头发还是先洗身体,应该先洗头发。在洗发的时候，水冲在身上，使身体的毛孔因受热而渐渐张开，“吐”出秽物，从而彻底洁肤。
有一些洗浴用品，在用过之后有滑腻的感觉，这是为什么,大部分洗浴产品不仅能净肤，还有护肤成分:一种偏酸性的成分。身体滑爽的感觉是对皮肤的呵护的结果，像保护膜。
什么时间洗澡最好,科学地讲，饭前和饥饿的时候就不要洗，容易造成缺氧和暂时性贫血，饭后立即洗也不好，最好是饭后一小时或更长的时间。睡前洗澡会消除一天的疲劳而使你轻松入睡，但长期湿头发睡觉容易掉头发。
回首二十世纪，人类在物质方面取得了巨大的进步，可是我们唯一的家园地球, 由于环境污染，却已变得千疮百孔。能源危机、大气污染、水土流失、全球变暖、赤潮、沙尘暴„„，人们不禁要问:“我们的地球怎么了?”.
环保节能已成为所有国家共同的心声。1992年联合国召开全球能源与环境发展大会之后，许多国家纷纷将太阳能列入重点发展项目。2001年7月5日，我国首次召开全国环保产业大会，将环保产业作为新的经济增长点，以实现可持续发展。而在北京申奥时，更是把“绿色奥运”作为申办的主题之一，把体育运动与环保活动紧密地结合在一起。环保，人人关注;环保，人人在行动～环that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity.

保，人人在从自身做起。使用环保能源，既节约能源，又无污染，正成为环保行为的首选。太阳能就是这样一种清洁、可再生的绿色环保能源。
随着人们对环保的日益重视，太阳能的利用也越来越广。太阳能的开发和利用，一方面可以广泛地应用于热水、发电、制冷、采暖、干燥等诸多方面，另一方面可以大量节省石油、煤炭等不可再生能源，大大缓解能源匮乏而带来的严重威胁。科学家曾预言，太阳能将成为21世纪的主要能源。
当前，太阳能利用中发展最快的是太阳能热水器。据权威部门统计，2002年中国太阳能热水器销量超过800万台，行业产值超过80亿元，而且每年正在以20%—30%的速度递增，中国已成为世界上最大的太阳能热水器产销大国。据检测，每平方米太阳能热水器每年可为国家节约标准煤150公斤，在其寿命期内等于减少燃煤向大气排放的二氧化碳256.6吨、一氧化碳136吨、二氧化硫352吨、氮氧化合物908吨。据专家测算，要达到发展中国家家庭洗浴和全天候使用热水的需求，全国4亿户家庭，每户每天按100公斤40摄氏度热水计算，全年需耗标准煤1.2亿吨。要解决这一问题靠常规能源是不可能的，因此大力推广太阳能热水器、利用太阳能资源才是当务之急。
使用太阳能，不仅是为了环保、节能、安全、舒适，也标志着人类生活观念的更新、生活质量的提高，更表明人类生活向文明化的转变。我们一直在关注自身、家人的健康状况，一直在培养良好的生活习惯，一场或许并没有走远的SARS也一直在提醒我们，一定要注意个人卫生、家人健康。因此，创造方便、舒适、节能、卫生的洗浴环境变得至关重要，太阳能热水器自身的优势、特
点，决定了它必将成为我们新生活的重要组成部分。自古以来，没有太阳人类将无法生存;而在新世纪，不使用太阳能，将是对自身、家人健康严重的不负责任。为了子孙的蓝天白云，为了您自身、家人的健康，您需要使用太阳能———太阳能热水器时代正向我们走来～
电热水器、燃气热水器、太阳能热水器是市场三大主流热水器产品。目前消费者选购热水器、燃气热水器时较多关注的是产品的安全性能，而太阳能热水器在安全性能方面当属最佳，那么在选购太阳能热水器时应该关注哪些产品性能呢, 其实，选购太阳能热水器有个黄金准则，就是太阳能热水器的综合性能关键要看其冬季的得热量。
影响太阳能热水器冬季得热量主要有以下几个因素:一是集热面积和集热性能。一般来说太阳能的集热面积越大，得热量越大，反之亦然。而在集热面积相同的情况下，真空管集热的性能则是影响太阳能热水器得热能力的一个重要因素。目前国内在真空管集热性能方面，表现最突出的当属皇明集团生产的三高“太阳芯”真空管，其集热性能远高于市场上常见的真空管。二是水箱的保温能力。太阳能热水器除了集热能力外，还要看它的保温能力。水箱保温层的厚度与材质是影响水箱保温能力的重要参数。三是太阳能热水器的倾角。由于中国幅员辽阔，南北方地理的差异和太阳辐射角度、强度的不同，要求太阳能热水器有最佳黄金倾角，根据中国大陆的纬度情况看，33?,55?为最佳设计角度。
此外，产品的设计理念也是影响太阳能热水器冬季得热量的重要因素。
综合上述因素，国内太阳能生产企业皇明集团率先提出以冬季好用为设计标准，推出新一代“冬冠180”产品，在集热能力、保温能力、倾角设计等方面均保证了产品在冬季的优越集热性能，被业界誉为“冬季得热冠军”。

随着人们生活质量的不断提高，每天足不出户洗个热水澡已成为一种现代文明生活时尚，经济方便的太阳能热水器可以满足人们这一需求。然而，面对琳琅满目的太阳能产品，消费者怎样才能买到一台称心如意的热水器呢,太阳能专家提醒消费者，选购太阳能要“四看”。
一看聚光集热效果。聚光集热能力的强弱是衡量热水器性能优劣的重要标志，也是影响热水器得热量的重要因素。真空管是太阳能的集热“心脏”，它将光能转化为热能，让水箱里的水热起来，所以相同外界条件下真空管得热量的多少，直接影响到水温的高低。目前，市场上有两种真空管，一种是采用传统渐变膜工艺制造的真空管，另一种是采用国际领先的干涉膜专利技术制造的，具有“耐高温、抗高寒、更高效”特点的皇明三高真空管，后者是前者的替代产品，它将热水器得热量提高了30%，彻底解决了传统真空管在阴雨天光照不足时水温不高、冬天温度过低时太阳能不好用的难题。
另外，今年市面上出现了一种“冬冠180”太阳能热水器，以冬季好用为设计基础，聚光集热能力更强，出热水多，升温快，多快好省， 180cm大真空管逐步取代传统小管太阳能，冬天也好用，代表了未来太阳能热水器发展潮流，是消费者享受绿色热水文明一步到位的选择。
二看保温性能。储水箱是热水器的“热水仓库”，它的性能优劣主要体现在保温效果上。好的保温水箱不仅要看保温层厚度，还要看保温材料及工艺。目前世界上最先进的生产工艺在中国，即采用全自动数控恒温恒压定量发泡，高温熟化处理，加厚保温层，确保了层质更加细密匀称，保温性能更持久。
三看支座强度。太阳能的支架就像人的“骨架”，弱不禁风当然不行。目前应用较多的是流线形塔式支座，它采用加强、超高底座，克服了传统细杆式支架单薄不抗风的不足，抗风、抗雨雪、抗冰雹、耐腐蚀能力更强。
四看品牌和服务。太阳能热水器主机在户外，常年经受风吹雨打，需要经专业人员维修、维护。目前国内有太阳能热水器厂家数千家，由于国家迄今还没有统一的太阳能热水器检测标准，部分产品质量不过关，安装服务不到位，给用户使用带来麻烦。有关专家认为，买太阳能买的不仅是产品，更重要的是服务。因此，应选择有实力的名牌专业厂家的产品，这样的厂家安装服务人员一般都经过专业技术培训，服务周到，让消费者无后顾之忧，获得最佳保障。
真空管是太阳能热水器的核心元件，被誉为太阳能热水器的“心脏”，真空管质量的优劣直接影响到太阳能热水器的使用寿命和性能，因此选择优质的真空管成了广大消费者的当务之急，下面就教您几种鉴别方法:
鉴别真空管质量优劣首先看外观，优质真空管的外观是:
,、表面光滑、干净，管身无斑点、无气线、无划伤、无划膜现象(此现象会影响集热效率和美观)。 ,、膜层颜色以蓝色、黑色为主，整体色差小。但黑色并不表明真空管质量好，因为有的厂家为掩盖杂色，往往把膜层做成纯黑 色。实际上，真空管在颜色上存在一定误差是不可避免的，并不影响真空管的集热效率。
,、烤消镜面完整，光洁透亮，无发黑、发乌现象。
,、目前市面上最好的三种真空管:高温管、高效管、高寒管。高温管膜层较普通管长(距管口约1;,)，此管耐高温，抗衰减性特强，膜层在400?高温空晒状态下，不老化、不脱落、不变色。 高效管膜层距管口约2.5;,，此管超高吸收，热损少，升温快，热效高。高寒管兼具高效管热效高、升温快优点的同时，热损更少，在,30?条件下照常出热水。消费者可根据不同区域选择不同的真空管。
,、用肉眼看，内管颜色为暗红色，表明它的金属底层是铜，这种真空管在严寒条件下也能正常工作，,30?照常出热水。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity. But the sensitivity of the balance are not only associated with these three factors, while carrying heavy loads and balance beam deformation, agate cutters of the fulcrum and the load point of the contact point (that is, agate and knife blades sharp and smooth).

优质真空管一般使用,,年以上，直接关系到太阳能热水器的寿命，在现今多数厂家水平参差不齐的情况下，消费者更应睁大眼睛仔细鉴别。
三高“太阳芯”真空管与普通管的区别在于吸热膜层不一样(吸热膜层是真空管的关键部位)。三高管是干涉膜，普通管是渐变膜。它们的区别主要表现为干涉膜与渐变膜的区别。
,、根本区别:膜层结构不同，导致吸收太阳光线的原理不一样。渐变膜，为多层膜，其吸收层一般是,层，它对太阳光线是逐层吸收的，而且其吸收光线的性能逐渐变高。由于这种渐变结构，发射比随温度上升不断加大，以致工作温度在,,,~,,,?时，发射比大大增加。而且吸收层中的铝离子在高温状态下，活泼性大大增强，并发生漂移。这样膜层的内部结构发生错乱，导致膜层开始老化。长期处于这种高温状态下，膜层就会脱落，从而影响了真空管的集热效率和寿命。 干涉膜，其吸收层共,层，两层膜之间，因金属成份的配比不同而产生干涉作用，使吸收比增加，发射比降低。再加上减反层减少反射的作用，从而实现更高的吸收比和更低的发射比，大大提高了集热效率。
,、特征:三高管的吸收比提高了,,,，发射比降低了,,,,,,,，超吸收，热损少，升温快。高效管，超吸收，热效高，升温快，在同样的光照条件下，比普通管能出更多更高水温的热水;高寒管，因铜离子的发射比比铝离子低,(,，因此热损很少，在高寒环境下仍能正常工作，,,,?照常出热水;高温特效管，因膜层中的不锈钢离子耐高温，抗空晒，膜层在,,,?条件下不老化、不衰减、不变色。
在相同光照条件下，普通管热吸收不如三高管高，甚至不能满足洗浴要求;在温度较低时，热损更大，集热效率下降，影响正常
使用;尤其在空晒超过,,,?时，膜层开始老化、脱落，吸收率快速降低，寿命大大缩短。
,、工艺:高温特效管、高寒管、高效管分别采用三靶、双靶、单靶磁控溅射工艺;普通管一般都采用单靶磁控溅射工艺。
,、外观:,、管口，此处膜层在,,,?以上高温状态下封口时，脱落一部分是不可避免的。高温特效管因耐高温，只有约,厘米长无膜层，而其它管因不耐高温，膜层脱落长度约,(,厘米。,、内管颜色:用肉眼观察，高温、高寒管的内管颜色为暗红色(因膜层底层为铜);而高效管和普通管为白色(因膜层底层为铝)。
总之，干涉膜是渐变膜技术上的新突破，是镀膜技术上的伟大创新和进步，干涉镀膜成为当前全球最先进的镀膜技术。同时也给真空镀膜技术带来划时代的变革。尤其是用干涉膜制成的高温特效管，还可用于制冷、干燥、海水淡化等，为真空管开拓了更新更广的应用领域。这项技术在中国的应用，皇明享有独家使用权。

二、如何判别太阳能热水器是否水满,
一般太阳能热水器安有溢流管，可根据溢流管是否排水判断水满状态，另外可以配备水位控制仪，水满自动报警，根据报警判别。 三、太阳能热水器上水应注意哪些问题,
由于真空管在空晒时，管内温度能达到,,,?左右，故在水箱内无水或第一次上水时必须在日出前或太阳落山半小时后进行。 四、 太阳能热水器长时间不用水，会热坏吗,
真空管太阳能热水器效率高，在夏季晴天的情况下，不到两天水温可达沸点，若长时间不用水，如出差、旅游时，使水箱内长时间处于高温、高压的状态下，会促进密封圈的老化，加速聚氨酯的老化、萎缩，有时排气不畅通，压力太大还会使水箱胀坏，还会结水垢，缩短水箱的寿命。因此，若你长期不在家，应安排别人经常放热水上冷水，或者在真空管集热器上放置遮盖物挡住阳光，待回家后，再除去。
五、太阳能热水器好几天未用的热水还能洗澡吗,
太阳能热水器好几天未用的水一般都是较热的水了，达到,,?以上，尤其在夏天晴朗天气超过,天，水就会沸腾，到夜间会适当降温，使水温保持在,,?,,,?区域时间很长，而这个温度区域是水中细菌繁殖的极佳温度，因此，如好几天或长期不用的热水，水质较差，细菌多，要排放掉，不要洗澡或用来烧开水等饮用，这样的水洗澡对皮肤不利，长期使用这种水洗澡会引发皮肤病。
六、为什么太阳能热水器频繁使用好,
太阳能热水器投入使用后，要经常使用，建议每天最好使用,至,次，间隔时间在,小时以内，这是因为: ?长时间地用水，对楼层较低的用户来说，所用到的水实际上是管道中的低温水(太阳能热水器里面的水停留在管道中降温后形成);尤其在北方冬季，外界气温低，有时达到,,,?以下，上下水管路内的水凉地很快，若是六层楼，一楼用户每次需放掉一脸盆冷水，特别浪费，如果频繁使用就好一些;
?能有效防冻，让上下水管路始终有热源，加上保温层，可有效防冻。在北方冬季，不少人还采用室内稍微打开热水器阀门，往下滴水的办法来防冻。 转载自“皇明网”

家用太阳热水器种类繁多，按照太阳能集热器种类可分为真空管式和平板式;按照结构可分为一体式和分体式;按照制作工艺可分为承压式和非承压式。目前，在市场上销售的家用太阳热水器最常见的大都是非承压真空管式家用太阳能热水器。一般的: 一看真空管:真空管是太阳能热水器最重要的部件，当前有粗管(一般直径为58mm)和细管(一般直径为47mm)之分。相对而言，粗管集热面积大，集热快，水温高，因此在选购时应优先选择运用粗管的太阳能热水器。
制造真空管的材料主要有单靶机和三靶机两种，其中三靶机的质量较好，消费者在选购时可以通过外观鉴别。单靶机真空管色泽呈灰蒙蒙状，有色差，同时真空管的内壁为浅黑色;而三靶机真空管外观偏蓝，无色泽差，内壁为暗红色。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity.

二掂重量:水箱对于热水器非常重要。一般重量重的水箱质量好。重量的轻重主要是由水箱外壳的用材以及水箱外壳与水箱内胆之间的发泡层决定的。
一般比较差的水箱，其外壳是用闪闪发亮的不锈钢为材质(当前不少大城市已经禁止使用这种材料制成的热水器，因为存在着光污染)，而且外壳的厚度不够，重量较轻。
发泡层直接关系到热水器的保温效果，因此对于热水器的使用也非常关键。一般名牌产品的发泡层采用机器高压发泡，使得外壳和内胆之间没有空气，同时发泡层密实厚重。因此，整个水箱掂起来往往较重。
三评支架:一般质量较好的太阳能热水器，其支架采用的是铝合金支架，厚实并且牢固。
?注:热水器的内胆质量无法通过外观来鉴别，这时消费者可以通过看说明书来判断。一般正规厂家生产的热水器不会对内胆的材质技术含糊其辞。因此，消费者在选购时要仔细看清说明书。
如何选购家用太阳能热水器
目前，市场上销售的家用太阳能热水器种类繁多，按照太阳能集热器种类来区分，可分为真空管式和平板式;按照结构区分，可分为一体式和分体式;按照制作工艺区分，可分为承压式和非承压式。目前，在市场上销售的家用太阳能热水器最常见的大都是非承压真空管式家用太阳能热水器。我们在选购家用太阳能热水器时，应注意以下几点:
1. 热性能指标中，“平均日效率”越高越好，“平均热损系数”越低越好。
2. 家用太阳能热水器的关键部件就是全玻璃真空太阳能集热管(简称真空管)，真空管质量的好坏直接影响到整个家用太阳能热水器的性能。选购时应仔细观察真空管内玻璃管上的涂层，这层涂层叫太阳能选择性吸收涂层，由于各厂家制作工艺不同，涂层
颜色会有所区别，但一般都是黑色、深蓝色或深灰色，质量好的涂层颜色均匀，膜层无划痕、无起皮或脱落现象，玻璃上也没有结石或节瘤现象，支撑内玻璃管的支撑件放置端正、不松动。
3. 选购时还应注意真空管之间的管间距，一般两管的中心距在70mm左右为宜。
4. 家用太阳能热水器的支架设计应合理，应有足够的强度和刚度才能确保有足够的承重能力。在一些日常风力较大的地区，尤其是沿海地区，在选购家用太阳能热水器时还应注意该产品在设计上是否有抗风能力。
5. 目前市场上，家用太阳能热水器的反光板形式多种多样，有平面反光板、曲面反光板、压花铝板等等，在选购时应注意产品的反光板设计是否能充分利用到真空管的吸热面，真空管能否最大程度上受光。
6. 在选购时还应考虑到家中常住人口数量，以确定所购买家用太阳能热水器水容量的大小。一般以每人40升水的标准为宜。另外，很多产品标称的容水量是通过计算每根真空管的容量和水箱内胆容量相加计算出来的，但其实在热水器出水口以下及真空管内的水是无法放出来使用的，用户真正能使用到的水仅仅是入水口和溢流口之间的水量，所以在选购时应问清楚销售商，他们所标称的容水量指的是全部的容水量还是实际能使用的容水量，两者相差多少。
7. 如果够买的家用太阳能热水器需要配置电加热装置，应选择具有电气安全设计的产品。
8. 选购其他相关配件，如自动上水装置、水温水位显示仪、电磁阀等，对于这些装置的选择应慎重，有些功能看似先进，但组成部件过多，可靠性不高，时间一长就容易出问题，选择时一定要问清楚使用寿命和保修期限。
9. 选购好一台家用太阳能热水器后，在安装过程中应注意支架安装是否牢固，所有螺丝及接头是否上紧，上下水管安装位置是否合理，热水器本身是否有加固措施等等。另外，在上水管路中一定要安装止回装置，以防止热水回流，倒灌入冷水管道。 that balances the sensitivity associated with the following factors: (1) the long arm of the scale, higher sensitivity, and (2) the beam of the scale is heavier, lower sensitivity, (3) pivot and the shorter the distance between the center of gravity, high sensitivity.

10. 家用太阳能热水器的售后服务也非常重要。最好选择知名品牌产品和售后服务好的经销商。因为家用太阳能热水器是耐用消费品，而且通常是安装在楼顶，一旦出了故障，用户很难自己解决，所以售后服务一定要有保障。目前，市场上整机免费保修期一般为3,5年不等。
11. 由于家用太阳能热水器是安装在户外，长时间使用，真空管上就会被灰尘或杂质污染，从而导致吸热效率降低。所以对热水器的真空管应定期清洗，特别在冬季多雪的地区，雪后更需要及时清理。如受房屋设计影响，自己无法清理的，应询问经销商，售后服务里是否包含有定期清洗一项。
