      With the social and economic development, water heaters have long been spread to millions of households. It is convenient, fast, comfortable and has become home to take a bath and enjoy life essential goods. And now the market water heaters, gas water heater from the initial, gradually increased electric water heaters, water heaters, solar water heaters, heat pump water heaters and other abundant species. Faced with so many varieties of water heater, water heater in the end what brand is good, but consumers should be how to buy it here for everyone to answer?:
 
A gas water heater
 
The first to market, generally coal or natural gas as the heating source, including displacement and fast style categories. Rapid gas water heater exhaust way divided by the vertical type, flue-type, strong emission-type and balanced. Since the vertical-type combustion exhaust gas discharged directly in the room, poor security, it has banned the production and sales. Flue consumes indoor oxygen combustion, combustion exhaust gas discharged to the outside through the smoke pipe. Strong emission in the flue on the basis of increased fan forced combustion exhaust outside, safety is further improved. Balanced indoor combustion does not consume oxygen, combustion exhaust gas directly into the room, good security. In addition, now that is hot gas water heater became the new darling of consumers, such as turboMAG series is Vaillant according to German standards of refined, efficient heat transfer can be achieved with the safe operation of the perfect combination of advanced digital technology to ensure accurate temperature control, comfortable bath .
Shopping tips:
1. Decides to installation location Product type: installation in relatively closed position, the best choice for elective strong emission-type gas water heater or balanced.
2. Select the home use the same kind of gas water heaters: Different types of gas gas water heater can not be mixed, therefore, before the purchase, you need to figure out what kind of home use of gas resources.
3. The selection decisions based on the geographical environment or the ordinary type of antifreeze: northern winter cold, ordinary gas water heater is cracking easily, while the southern winter use common types of gas water heater on it. Typically antifreeze product prices slightly higher, choose the right product according to the actual geographical situation, cost savings, more convenient to use.
4. See Product Naming Analyzing gas water heater exhaust way: Since the vertical-type water heaters, security risk, the state has banned the use, but some still illegal vendors in order to reap huge profits in the sales, it is prone to danger. Exhaust gas water heater belongs to what, you can see the product name to distinguish: JS representatives of gas water heaters, followed by Z represents a vertical-type, D behalf of the flue, G on behalf of strong emission-type, P for balance.
5. Other options Note: It is recommended to select such as Germany Vaillant other famous brand products, to buy time to pay attention to see product quality inspection certificate. Note View service, warranty, whether extended warranty, whether provide on-site installation, free maintenance and other services.
Second, the solar water heater
 
Use of solar energy, green energy, is more fashionable and environmentally friendly way to an energy source. But the installation site is generally in the roof or sufficient light to take place, site leveling and other needs, living conditions of urban residents less able to meet the requirements. And is affected by climate, we need to install solar water heaters, auxiliary heating systems.
Shopping tips:
1. Note that the form of the water heater. See the positional relationship between the collector and the tank section, divided into compact and sub-forms. Compact roof tanks are too heavy when you could easily lead to roof leakage; split water tank is located indoors, collectors located on the roof of a building surface load unlikely.
2. Note that if the water heater pressure. Pressurized solar water heating system more complete performance, high degree of automation, quality guaranteed, the scope of a broader, long life; simple unpressurized solar water heater performance, lower prices.
3. Note the collector form. Vacuum tube collectors Peace plate is divided into two types: vacuum tube used for ordinary non-pressurized solar water heaters, water quality is not good to go inside, broken after the water heater does not work; flatbed for pressurized solar system would not be too heavy for the roof pressure, easy to combine with the roof, does not destroy the building exterior.
4. Note the water heater tank. Market selling stainless steel liner and the enamel interior two kinds. Stainless steel liner which is poor in quality interior seams process, the general life of about five years. Enamel interior is divided into ordinary enamel, advanced ceramics, titanium sapphire enamel interior; ordinary enamel interior life of about two years, senior general enamel interior life of 5 years.
5. Note the hot water heater performance. The higher the efficiency, the better day, heat loss coefficient as low as possible.
6. Note the auxiliary heating performance. Generally divided into heat and electric auxiliary boiler auxiliary heat. General electric auxiliary heating power is small, it can guarantee the use of hot water every day, but do not need to have anti-dry function. Auxiliary boiler thermal power is generally larger, the heating time is short, use the controller to achieve coordinated operation of heating and domestic hot water.
7. Note the service. The best choice as Vaillant auroTHERM / MATIC this well-known brand products, solar water heaters because of family is usually installed on the roof, so the installation of the service must have a selection of products and after-sale protection.
Third, electric water heaters
 
Electric water heaters and electric water heaters include volumetric electric hot water heater, the current market share is large volume electric water heater. Volume electric water heaters, also known as water heaters, kettles and similar principles, simply means that the first pan, with water. Advantages volume type electric water heater is safe, the disadvantage is bulky, easy to scale and clean the internal trouble, slow heating, process water need to adjust the water temperature. Electric hot water heater is a rising star electric water heaters, heating by high-power heating tube short precipitation, the advantage is fast heating, small size, high efficiency. The disadvantage is most suited to fast - Bed line electric water heater, and security issues worrying comparison.
Shopping tips:
1, the general family of three, choose the size of the water heater 80L is appropriate.
2, confirmed the suitability of the home electrical wiring.
3, brand and material selection must be cautious, because the water can conduct electricity, a good brand and good electrical resistance of a material is the secure protection.
Fourth, the heat pump water heater
 
Heat pump applications in foreign countries has nearly 40 years of history, but China is concerned, it is still a new technology, domestic heat pump water heater, especially immature. Its birth date, due to the low market awareness, and so expensive, basic customer groups are those housing conditions, high income, high-end users a large amount of hot water used in the factory or company.
Shopping tips:
1, the family economic conditions within our capabilities.
2, choose foreign brands and domestic brands of high-tech products is appropriate.
