The difference between central heating and self heating, which will be better, central heating or se

Comparison of self-heating and central heatingCentral heating is different according to the different heating time of the region, which has formed a limitation to a large extent, the climate is different every year, and the time when the cold arrives will not be the same every year, but the central heating makes people have to wait until the heating time to enjoy the warmth. However, self-heating does not have this problem at all, and users can enjoy a warm environment at any time. The time and temperature of central heating cannot be controlled by the residents themselves, and the heating temperature is hot and cold, unstable, and the user cannot adjust it by himself.

Any kind of self-heating equipment can be freely adjusted and controlled, and the temperature will not be too high and too low. The biggest advantage of self-heating compared with central heating is energy saving, central heating wastes a lot of heat on the pipeline, and the efficiency of self-heating heating is very high. In addition, the cost of self-heating is lower than that of central heating, and a wall-hung boiler with a rated gas consumption of cubic meters per hour.

For example, if the heating is in a house of about 100 square meters, the room temperature is constant, and the wall-hung boiler runs for 5 hours, the daily gas consumption is cubic meters. The cost of self-heating wall-hung boiler per heating season: cubic meter yuan cubic meter 100 = 2563 yuan; Central heating bills:

100 square meters 30 yuan square meters = 3000 yuan. Of course, if the condensing wall-hung boiler is used, the heating cost of the gas wall-hung boiler will be less.

Heating is basically divided into self-heating and central heating, generally most areas in the north are central heating, the north is colder, winter heating is the demand of all people, and the south is more inclined to self-heating. Relatively speaking, the winters in the south are not so cold. So what is the difference between central heating and self-heating?

Let's follow the golden flagship flag brother to find out.

Compared to the north, the climate is windy and cold, the walls of the building are thicker than those in the south, and the sealing is also very good, which is suitable for central heating. In the south, it is more troublesome to achieve central heating, and the heat will run out, resulting in the loss of resources.

From the point of view of flexibility, central heating is not as operable as self-heating, central heating mainly depends on the situation of the heating company burning the boiler, as well as the distance and the size of the water pressure, and the temperature is not controlled by itself.

From the point of view of energy saving, central heating is planned uniformly, and some families are away for a long time and only use it for a certain period of time, but they are also forced to accept a quarterly fee. Causing economic losses. The temperature is unadjustable, and the temperature in the home is too high, and the windows need to be opened for ventilation, resulting in energy loss.

From the perspective of environmental protection, central heating is basically achieved by burning coal, which will emit a large amount of polluting gases and cause air pollution.

But in fact, the cost of self-heating is also quite large, if there are people at home for a long time, the heating cost is also a large expense.

Steel radiators can be used for central heating, because the heating water quality of central heating is alkaline and the oxygen content is very low; If it is self-heating, it is recommended to use copper-aluminum composite radiators, strong corrosion resistance, long use time, there is a term in the industry called "aluminum is afraid of alkali, steel is afraid of oxidation corrosion, copper is afraid of electrolyte", it can be seen that radiators of different materials may not be used together, in order to avoid unnecessary losses caused by corrosion, it is recommended not to mix.

Some people envy central heating, and some people yearn for self-heating, it depends on how you choose.

Concentration means that the heating of many buildings is transported to each household through pipes. There is a time when the weather is cold in advance and cannot be heated in advance.

Nowadays, many newly built buildings use hanging fireplaces to boil water for heating, which can be turned on and off at any time according to the weather conditions, which is convenient and free.

I see.

If there are self-heating conditions, the self-heating effect is better, but the cost of central heating will be higher.

However, because the heated water or steam is transmitted to the home through the heating pipes, there is a loss of heat during the transmission process. Therefore, it will cause the phenomenon of temperature difference in the same building in the same community.

However, the disadvantage of self-heating is that it is significantly more expensive than central heating.

When decorating a self-heating house, it is necessary to take into account the insulation of the house, such as installing well-sealed doors and windows, installing double glazing, sealing strips, etc., so as to reduce heat loss. It can improve the efficiency of self-heating and reduce the cost of self-heating.

If the radiator has good heat dissipation, then the balance and stability of the room temperature can be ensured, and the heat can be quickly dissipated, the room temperature can be quickly increased, and the gas consumption can be reduced. It will not affect the comfort of heating, and it is also very gas-saving and cost-saving.

3. How much is self-heating a month?

Taking the heating cost of gas wall-hung boiler in Beijing as an example, if you want to use gas wall-hung boiler to heat a 2-bedroom house of 80 square meters at 26 degrees for 8 hours, you need to consume 7-8 cubic meters of gas.

If you heat for 8 hours a day for a month, then you need about 500 to 600 yuan for heating. If it runs 24 hours a day, the cost will be around 1200.

Self-heating money-saving strategy:

1) The temperature should not be too high:

When using self-heating, make sure that the temperature of the room is not too high. The temperature is suitable, so that you can not only enjoy the warmth, but also achieve the purpose of saving money.

2) Don't use it for too long:

When using self-heating, you can turn off the wall-hung boiler before going to work in the morning, or adjust the temperature of the wall-hung boiler to 20 degrees Celsius to reduce gas consumption. In order to achieve the purpose of saving money.

3) Sub-district heating:

Heat can be reduced by turning off the heating valve in rooms with less active time such as the kitchen and leaving only the living room and bedroom heating**.

What is the difference between central heating and self-heating?

Central heating is indeed more cost-effective. The economy is the best in terms of scale effect, but why is central heating only realized in cities and not in rural areas? It is also a scale effect.

A fourth-tier city with a 5-6 km square area, where hundreds of thousands of people are concentrated, and houses are densely packed, especially for buildings. Even the same population, if in the countryside, must be a hundred kilometers square. In contrast, the cost of laying pipes, the amount of heat required to heat the same area, is an order of magnitude difference.

In addition, facilities such as urban central heating infrastructure are what you pay for when you buy a house. And, without you knowing.

As the style of modern home decoration becomes more and more diversified, home radiator as the trend of modern home life, home radiator has entered more and more families. In order to make the household radiator beautiful, fashionable and in line with the overall style of the family, a lot of energy has been invested in both heating and the user himself.

1. The heating time is long, the general heating day is from mid-November to mid-March of the following year, and the heating system is generally used for about 4 months, and it can reach 5-6 months in some parts of China. Long-term high-temperature heating is a severe test for the performance of the system.

2. The heating pressure is large, the central heating pipeline is long, the heating area is large, and the heating temperature must be maintained in a certain area. These determine that there is a lot of pressure inside the whole system, which can ensure that the hot water provided by the heat source company is continuously delivered to the user's home.

3. The heating environment is complex, the whole central heating system involves various families, in which the oxygen content and impurity content of circulating hot water are constantly changing, the equipment configured in the system is not uniform, and the heating environment is complex, especially the impact of water quality on the system is particularly obvious.

1. Central heating is safe and trouble-free, but the heating time is calculated according to the heating company, and it is impossible to send heating when it is a little colder, and the heating date must be obtained. It was still cold in early spring, and the heating company said that the heating must be stopped after the heating period ended. The heating temperature is also a calculation that the heating company says.

The temperature in the heating room wants to reach 22, but the heating company says that it is reached at 18. If the central heating system is not hydraulic, and the heating at home is not hot, I think it is better to use gas to heat the heat. 2. In terms of heating costs, you should save some of your own household gas combustion heating.

More than 20 yuan per square meter is enough for Beijing's own household gas-fired heating, and 28 yuan per square meter for central heating. 3. In terms of initial investment, buy a wall-hung boiler for 5-6000 yuan, and you don't need to spend this money on central heating.

Central heating or self-heating depends on their own conditions and their respective needs, central heating is based on different regions and different times, respectively. He does not have the convenience and freedom of self-heating, and the temperature of central heating cannot be controlled by himself, but central heating is energy-saving and economical. Therefore, if you want to facilitate self-heating, if you want to save energy, you can use central heating.

Central heating is good, China's central heating technology is relatively mature, safe and convenient to use, can be heated around the clock, the cost is charged by the first unified charging standard, the first is cheap. However, it has obvious defects: the temperature and time of heating are not controlled by themselves, and the three-dimensional radiator is not beautiful, occupies space, and affects the indoor decoration effect.

It must be that central heating is better, especially central heating, first of all, it is relatively clean, and it is also warmer, which is very good.

Collective heating is better, because residents in the north use collective heating, and the temperature is also very high, and it is not expensive.

Central heating would be a little better. Because after all, the heating is more uniform, and the price is relatively cheap, which is very cost-effective.

Compared with the two, of course, central heating is better, so it is more balanced, you don't have to worry too much about yourself, and the temperature is also higher.

Central heating is better, and now the state also recommends the use of this heating method, which costs less money and is particularly clean and convenient.

What is the difference between central heating and self-heating?

1. The advantages of central heating: China's central heating technology is relatively mature, safe and convenient to use, can be heated around the clock, and the cost is charged by the first unified charging standard, which is cheap. But it has obvious flaws:

The temperature and time of heating are not controlled by themselves, and the three-dimensional radiator is not beautiful, occupies space, and affects the indoor decoration effect.

2. The advantage of gas wall-hung boiler is that it is highly controllable, which can meet the heating needs of multi-bedroom rooms, and each room can be set at will to set the comfortable temperature according to the needs, and it can also decide to turn off the heating in a room separately according to the needs, and can provide large-flow constant temperature sanitary hot water for family bathing, kitchen and other places.

The disadvantage is that the cost is higher, and it is necessary to pay attention to maintenance and regular cleaning, and regularly add anti-corrosion, which is not as worry-free as central heating.

3. Central heating and wall-hung boiler to burn gas, the latter is warmer. Because the gas wall-hung boiler has a powerful home heating function, it can meet the heating needs of multi-bedroom rooms, and each room can set a comfortable temperature at will according to the needs, that is, you can adjust how warm you want.

4. In terms of economy, central heating is cheaper. Central heating is mainly a heating method that uses urban heating network, district heating network or large-scale central heating as the heat source. In China, there are many ways to use central heating.

Central heating refers to a form of centralized group heating. Generally, it is charged per square meter (floor area) for a heating season, and for the northern regionThe weather is colder and you need to heat for a long time, so you should save money by central heating.

In terms of energy utilization, the one-time investment in central heating is large, the operating cost is high, whether it is needed or not, the heating is always heated all day, and the temperature is uneven due to different floors.

Disadvantages of central heating:

1. Central heating has many advantages, of course, it is inevitable that there are inherent shortcomings, its early cost is very high, the construction scale is large, and the cost of heat network construction is high.

2. The heating time and temperature cannot be controlled by yourself, that is to say, you cannot make personalized choices. It is unified, sometimes winter may come early, but the heating has not yet come, winter may have gone, but the heating is still there.

3. In recent years, the state has vigorously carried out air control, especially in the areas with serious haze in the north, the implementation of central heating can effectively reduce the emission of pollutants in the air and achieve energy conservation and environmental protection. And in the future, central heating will become the main form of urban heating, which is also the general trend of urban planning.

In the north, central heating is the main supply, and thermal energy** is mainly produced by the combustion of coal in thermal power plants. Due to the large user base, the flexibility of adjustment is relatively weak. Because the central heating will be affected by the boiler operation of the thermal power plant; the distance of the distance; Under the influence of water pressure and other factors, the indoor temperature of different users on the floor is high and low.

From the perspective of energy saving, it will bring inconvenience to users due to the fixed heating time. The heating temperature is relatively unadjustable, so some customers are passively accepting, such as due to work trips or short time at home, and the central heating cannot be stopped, resulting in economic losses; Due to the difference in floors, the indoor temperature of each floor is different, some are too high, some are too low. Some users can only open the windows to cool down because the indoor temperature is too high, which will cause a waste of energy.

From the perspective of environmental protection, the thermal energy of central heating in northern China mainly depends on the combustion of coal in thermal power plants, and a large amount of exhaust gas generated by combustion causes air pollution. Recently, many regions have successively introduced policies to reduce air pollution.

Due to the different heating habits in the north, most of the southern regions use independent heating systems. The independent heating system has great advantages in residential buildings represented by residential buildings with strict energy-saving ambient temperature, strong independence of operation regulation, and need to charge fees according to different heating units. China's extensive emerging heating area, is China's most economically developed area, although the lack of centralized mining pipe network, but in recent years the heating demand is expanding day by day, independent heating system has become a better choice for the above areas.

From the perspective of heat source efficiency, independent heating generally uses clean energy such as natural gas and electricity, and the difference between small equipment and large equipment in terms of combustion efficiency is very small.

From the perspective of energy saving, the energy consumption of transmission and distribution is very close to the heating part, and the pipeline is directly laid indoors, so the consumption and heat loss of transmission and distribution pumps are negligible.

From the perspective of reliability, the heat source is scattered and the number of fault points increases, but the failure of a single heat source does not affect the heating of other users, and the water capacity of the system is small, and the harm of leakage is small.

From the perspective of operation control, it naturally realizes household control, automatic operation of equipment, flexible switching, independent control of heating time, and no one in the room can be turned off, providing an effective means for active energy saving.
