What's the difference between central heating and wall-hung boiler household heating?

A, central heating and wall-hung boiler household heating is very different, mainly:

Household heating means that each household uses an independent heating pipe; Collective heating is generally the whole building, or the whole community has a total heating pipeline system. From the perspective of one-time investment, domestic wall-hung boiler heating is much less than central heating, saving investors' investment costs.

The direct investment costs of collective heating include heating interface fees, building residential heat exchange stations, laying residential pipelines and maintenance fees. From the perspective of direct investment, household heating is obviously superior to central heating, and each household only needs to be equipped with a wall-hung boiler, so the comprehensive benefit is better. Real estate developers can also reduce the cost of property management, and will not bring a lot of trouble because of heating costs, thus bringing good hidden economic benefits to real estate developers. Wall-hung boiler is an energy-saving and environment-friendly product, which conforms to China's energy policy and is the direction of heating. The government advocates and encourages development, and the elimination of central heating boilers with high energy consumption and heavy pollution is bound to be limited in the future. Some cities in China have issued policies that new houses must be heated separately in the future. Real estate developers should pay more attention to the scenery, conform to the trend, adopt promising products, and avoid the troubles caused by future decoration, and the real estate has more room for appreciation.

In terms of gas supply mode, domestic wall-hung boiler heating is more reliable than central heating in safety:

Central heating is equipped with special valves, flow meters, pressure regulating boxes and special safety protection devices for boiler rooms. Because the pipeline is long, there are many links, the possibility of problems is relatively increased, and maintenance is frequent, so the requirements for its equipment, accessories, pipelines and construction are very high, and there are strict technical requirements for the management and operation personnel of the boiler room, otherwise it will easily lead to more harmful accidents. In order to avoid unexpected losses, users often have to invest a lot of money to buy insurance.

The gas used for household heating and the civil cooking stove use the same pipeline, and there is no need to add new equipment and pipelines. The boiler room is a major danger point, so the safety and reliability are greatly improved, and users do not need to pay high insurance fees.

In combustion equipment, domestic wall-hung boiler heating is safer than central heating;

Central heating must use large boilers with high pressure and large cavity space, and use special burners. Safety protection mainly depends on special burners. Once the control fails, the furnace will explode and cause a chain reaction, which may lead to accidents.

The heating control of household wall-hung boiler is simple and clear, with complete self-protection function, high degree of automation, many protection devices and high reliability. When there is a problem, the machine will automatically give an alarm and stop. Quality after-sales problems are all solved by wall-hung boiler manufacturers, which saves the long-term maintenance cost of property companies.

As far as combustion mode is concerned, domestic wall-hung boiler heating is safer than central heating;

The central heating boiler burns indoor air, and the exhaust gas is discharged into the atmosphere through the chimney, which may cause indoor hypoxia and cause great pollution to the atmospheric environment. In this regard, the national environmental protection department has repeatedly requested that the use of small coal-fired boilers be banned and that small boilers be strictly investigated. The environmental protection situation of urban central heating is also very worrying. The urban environmental problems in China are mainly caused by coal burning, and the urban air is characterized by typical soot pollution. 90% of SO2 in the atmosphere comes from coal burning, the amount of coal used in heating period increases, the concentration of SO2 in heating period seriously exceeds the standard, and 2/3 of total suspended particles come from smoke and dust. Burning a lot of coal also makes China a big country of carbon dioxide emission, ranking second in the world, second only to the United States. The domestic wall-hung boiler is used for heating, and the combustion air is taken outdoors, and the combustion exhaust gas is discharged outdoors, so the combustion is sufficient, and the exhaust gas index is generally good, which will not pollute the indoor air and cause carbon monoxide poisoning, nor will it cause indoor environmental pollution.

In the case of combustion leakage accident, the possibility of domestic wall-hung boiler heating is much smaller than that of central heating:

Central heating may be due to the large boiler room, many dead angles such as warm ditch and warm ditch, and closed doors and windows in winter. In the event of air leakage, it is prone to explosion accidents. Domestic wall-hung boiler has few heating and gas supply links and many safety measures. There are triple overheating prevention devices and triple anti-freezing devices, and the installation rooms are isolated, so the possibility of gas leakage is extremely small.

In a word, domestic wall-hung boiler heating is safer and more reliable than central heating in all aspects. Once the central heating fails, the whole downstream cannot be heated, which has always existed in the northern cities of China in winter. Household wall-hung boilers are provided by manufacturers and are generally faster.

From the perspective of operating cost, the heating and energy-saving effect of household wall-hung boilers is very significant.

At present, a lot of data and practice prove that the running cost of wall-hung boilers in northern winter is about 16 yuan /m2 (different brands have different costs), which is much lower than the collective heating price of 22 yuan /m2. Moreover, due to the rising of coal energy and labor wages, this cost is increasing year by year, and it is increasing by about 2 yuan /m2 in Shandong every year. Wall-hung boiler is flexible and convenient to use because of its low operating cost, which improves the living standard of buyers and has a high enthusiasm for buying houses. It is also beneficial for real estate developers to sell houses, thus improving the value of real estate.

Second, the independent heating system:

The characteristic of independent heating mode is that users can choose according to their own preferences, and can also measure heat together. With the application of clean electricity and the emergence of new technologies and new products, it is possible to choose a variety of heating methods, and the exclusive position of central heating system is challenged. There are many methods, such as independent home heating and integrated heating and hot water. The commercial development of housing and the emergence of large-sized apartment, duplex, double-bathroom and multi-bathroom villas further increase the demand for domestic heating equipment and domestic hot water.

Third, the central heating system

The so-called central heating system is a heating mode in which one or several central heat sources supply the production heat and daily heat needed by users through the heating pipe network. Compared with boilers or small stoves with decentralized heating, it is an important way to effectively use electricity to prevent air pollution. The central heating system can be completed by cogeneration, regional centralized boiler room construction and industrial waste heat.

1. Central heating system is manifested in the following aspects:

1. 1 has good economic benefits.

Because the boiler used in central heating system has large capacity and high thermal efficiency, which can reach more than 90%, while the thermal efficiency of small boilers with heat dissipation is only about 60%, or lower. Therefore, urban central heating system can save electricity by 20 ~ 30% instead of lax heating.

1.2 Good environmental benefits.

Urban pollution mainly comes from carbon dioxide and smoke produced by direct combustion of coal. The central heating system has a large boiler capacity and relatively complete dust removal equipment. If you choose a high-efficiency dust collector, the dust removal efficiency can reach 90-98% or even higher, which can effectively reduce urban pollution.

2. Advantages of central heating system:

2. 1 Better skills, safety, reliability, simplicity and low price.

2.2 24-hour heating.

2.3 It is cheap and suitable for families with old people and children who need continuous and safe heating.

3. Disadvantages of central heating system:

3. 1 The heating time and temperature cannot be controlled by itself, and the vertical fins are unsightly, occupying space and affecting the decoration effect.

3.2 There is no heat source before and after the heating period.

3.3 Radiator heating, usually the water temperature is above 70 degrees Celsius, but when the temperature reaches 80 degrees Celsius, a dust mass will appear, which will cover the wall above the radiator with dust.

3.4 Households can't adjust the heat according to their own needs, and they have to pay the same money if they can't live.

4. The central heating system cost:

Take a room of 100 square meter as an example. According to the regulations of Beijing, the operating cost of gas heating is 24 yuan/m2. A heating season is 2400 yuan.
