Are there any good brands of wall-mounted gas boilers? Introduce something cheaper.

1. Weineng (The wall-hung boiler they invented has the best performance and appearance! Committed to the research of environmental protection equipment, such as fuel cells, using natural gas as fuel source for the energy consumption of the whole family, including heating, domestic hot water and electricity. This brand is the most expensive, so it's your luck.

2. Barderas: The steel plate boiler is better than others, but it is a big boiler, and more than 2 tons is an advantage.

3.viessmann: cast iron boiler is better than others, but it is also a big boiler with the advantage of less than 2 tons. Since the wall-hung boiler has been produced in Shunyi, the price should be lower than the last two, similar to Italy.

4. Yima: Italian brand, because the agent is very background, so some projects without background, foreign developers and government background (including rebuild houses) will choose this brand;

5. There is also Ou Xianba Xi, which sells well in Europe, but most of the products bought in China are low-end products, which Vanke Qingqing uses. In addition, there are Korean, Japanese, joint venture Yan Di and other brands. I think Germany's prestige is the best. The other two brands in Germany are similar to Italy, followed by France, Japan and South Korea, all of which were above 3,000 in the past.

6. I used the wall-hung boiler in Shuguang Garden for three heating seasons, which is also Yima's, and the cost is not that high. Cooking with hot water heating belt costs 24 yuan per square meter. I think it's a good deal. Compared with central heating, it saves six yuan per square meter, which is about 600 yuan in one season and updated once every ten years. Don't forget, the cost of hot water and cooking is also included in this 24 yuan. You're not talking about heating, you're talking about burning money. It's not even Korean, let alone imported from Europe. No one will believe you if what you say is ridiculous.

A, wall-hung boiler brand classification:

Wall-hung boilers are divided into two categories: imported and domestic joint ventures.

Original imports are divided into regional brands such as Germany, Italy, France and South Korea. Domestic joint ventures are divided into assembly plants and joint ventures.

1, German brand: Weineng, wiesmann, Doctor.

The above three brands have their own characteristics: ① Weineng, imported from Germany. (2) viessmann, assembled in the original factory in China. Doctor, the company is registered in Germany. The factory is located in underdeveloped countries such as Turkey, and its products are exported from Germany. The quality and structure are similar to those of water heaters in Chinese township enterprises. This is the most deceptive fake German product, without any real explanation, indicating that the product is from Europe.

Weineng and wiesmann are internationally recognized brand-name products with first-class operation effect and production quality. However, problems such as acclimatization, high price and slow delivery of spare parts have restricted its development in China.

2. Italian brands: France Luo Li, Beretta, Ouxian Baxi and Yima are imported, and most of the others are domestic OEM. The main products of the first three brands are not wall-hung boilers, but integrated manufacturers of large boilers, air conditioners and radiators. , strong, but the main business is not outstanding. Only Yima is an Italian factory specializing in the production of wall-hung boilers. Only wall-hung boilers are developed and produced, and there are no other products. Because of their professionalism, they are dedicated, so their fame in Europe and China is greater than their scale. The market share of the four brands in Beijing is about 5% for Faroli, 5% for Beretta, 2% for Ouxianbashi and more than 50% for Yima. These data can be found at the customs.

3. Domestic joint venture brands

(1) OEM products, that is, domestic but imported products, such as ariston. These products are both imported and made in China, so it is easy to steal the column.

② Joint venture brand: the main parts are imported parts, sheet metal and shells, which are produced in China and listed after assembly, such as Squirrel, Ruoke and Dong Qing.

(3) Pure household wall-hung boilers, all kinds of original factory accessories are purchased nationwide, and then assembled, which does not have the production capacity of any major parts. Most of the places of origin are Sichuan: such as Chengfa Jubao.

Second, the selection points of wall-hung boiler

1, brand selection. Generally speaking, choosing a good brand means choosing safety, fuel economy, worry and service. Manufacturers can make promises in every way when promoting their products, but there are not many that can really be done according to their promises. Because there is not enough ability and financial resources, it is impossible to support after-sales service and ensure the timely supply of accessories. In addition, you must choose a wall-hung boiler with a product insurance policy, and the manufacturer is responsible for the accident.

Choosing a brand is the biggest headache for developers. The government has no hard and fast rules and no hints. It all depends on the developer's conscience and his financial resources. If you choose the original imported brand, the initial investment will be large, but there will be less trouble behind it and high grade. If you choose a joint venture, the initial investment is small, but there are many troubles behind it, many exposure opportunities and low grades. So developers formed three factions when choosing brands. One school at a time, choose the original imported brands that everyone can rest assured. One school is a low-end joint venture brand that chooses the reserve price. Anyway, the trouble is the property and the owner. The third faction chooses a joint venture to organize the owners to replace the original ones.

It is a great blessing for users if Sanhuan New Town can choose imported brands. I only heard that developers have menu-style decoration, but I have never seen menu-style equipment procurement. If developers can really discuss equipment problems with users, it shows that they are sincere and open-minded, which is also the first case in China and is commendable. I hope to choose imported brands.

2, choose power, the same brand has a variety of power choices. The power chosen is large, which wastes money and energy. The selected power is small and the waste of capital and energy is small, but it can't meet the use requirements.

Two conditions must be met to meet the demand for electricity: heating and sanitary hot water. In Beijing, the heating rate of wall-hung boiler should be calculated as per square meter 120W, and the power of sanitary hot water should be above 10 L/min (△t=30℃), both of which must be met to meet the use requirements. That is to say, stoves above 20KW can be used. If you choose 18KW cooker, the heating is fine, but there is too little sanitary hot water.

3. Optional service: The service life of the wall-hung boiler is more than 15 years. In addition to the two-year warranty, there is also a minimum of 13 years of paid maintenance. In the long years of 13, if there is no good service to escort you, it is really difficult. This choice can't be heard from the manufacturer, it must be examined. Look at the size of the company, look at the warehouse accessories, look at the maintenance site, and look at the user feedback.

As long as we grasp the above three requirements, we will be able to choose our favorite products.

Third, the price range of wall-hung boilers (taking about 23KW as an example)

German original 7000-8000 yuan German assembly 6000-7000 yuan Italian original 5000-6000 yuan Italian assembly 4500-5000 yuan joint venture imported parts 4000-4500 yuan domestic assembly machine 3500-4000 yuan (actual price: less than 3000 yuan. For example, the price of Chengfa Jubao is only 1944 yuan, and the price for developers is 3800 yuan)

If the developer can minimize the price of the original Italian boiler, it will be close to the price of the joint venture product. The advantage of the Third Ring New Town is that manufacturers can gather at will, and the quantity is huge, which makes people jealous, but no one will do business at a loss. There is a certain limit to the price reduction, depending on the ability of developers.

Four, can't choose the brand are:

Chengfa Jubao (assembling parts or even purchasing parts from stalls) is a "three noes" unqualified product.

There are some technical and manufacturing problems with this product.

Verb (abbreviation for verb) about authentication and testing.

European original wall-hung boilers must obtain the following international certifications.

CE0063 quality certification, 90/396/CEE efficiency certification and EN483 pressure standard certification.

Non-original imports do not have these certifications, but only the test reports of domestic gas appliance testing stations.

Six, environmental protection standards

Beijing's environmental protection standards mainly include the following four items about wall-hung boiler projects:

1, and the smoke emission concentration is less than 50mg/m3; 2, SO2 emission concentration is less than 50 mg/m3; 3.NO2 emission concentration is less than 300mg/m3；;

4, running noise is less than 55 decibels.

Seven, antifreeze characteristics

Wall-hung boilers must have perfect anti-freezing function.

1, automatic anti-freezing function: when the water temperature drops to 5℃, the boiler must be able to start automatically; 2, when expired, at 5℃, the water pump should run continuously. These two functions can prevent accidents in winter.

The above personal views are inevitably shallow and can be laughed at. If you want to listen to PPR subway next time.
