What is the meaning of central heating, the difference between central heating and natural heating, and the charging standard of central heating.

What does central heating mean? Central heating refers to a form of centralized collective heating. Generally, it is charged per square meter (construction area) in a heating season. For the northern region, the weather is cold and it takes a long time to heat, so central heating should be used to save money.

In terms of energy utilization, central heating is a one-off operation with high operating cost. Whether it is needed or not, it is always heated all day, and the temperature is uneven because of different floors. If the heating is too hot, residents have to open the window to cool down, which wastes valuable energy.

There is a power pump in the central heating system, and even a small heating system has an axial pump to drive circulating water.

In domestic floor heating, it is generally circulated by gravity. The inlet of radiator is higher than the outlet of heating furnace. When the heated hot water becomes lighter, it will "rise" into the radiator. After heat exchange, the circulating water in the radiator becomes colder and heavier and flows back to the heating furnace.

Central heating is environmentally friendly and safe. There are two main heating systems in residential buildings: central heating system and household heating system. Central heating means that a centralized heat source transfers heat to users through pipes.

Central heating in Beijing market is mainly boiler and urban heating network heating, and household heating includes wall-hung boiler heating and electric heating.

Difference between central heating and natural heating

What's the difference between central heating and natural heating? In fact, some users can't distinguish between central heating and natural heating.

1. Relatively speaking, central heating will waste some resources. Simply put, when the family is not at home, there is no need for heating indoors. There is no way to temporarily turn off the heating for central heating.

And natural heating refers to self-heating. This kind of home heating can be suspended. So unnecessary resources will not be wasted.

2. Generally speaking, central heating can effectively use cogeneration, industrial waste heat and renewable energy as heat sources. The combustion efficiency of large-scale combustion equipment is higher than that of small-scale equipment. Indoor comfort is naturally relatively high.

However, clean energy sources such as natural gas and electricity are mostly used for natural heating, and the combustion efficiency of small equipment and large equipment is still different. The comfort is relatively poor, and the price will be slightly more expensive.

3. In terms of environmental protection, central heating and heat source management will make it easier to deal with and control emissions such as smoke and dust.

Naturally heated gas tail gas is directly discharged on the spot. The general natural heating uses clean energy, which has relatively little impact on the environment.

4. Central heating is the centralized maintenance and management of heat sources. If something goes wrong, the heating of the whole building will be affected. This is not good.

And natural heating, heat sources are scattered, although the number of fault points will increase, but if there is a fault, it will not affect other households.

As mentioned above, central heating is a relative waste of resources, so naturally there is a problem that we will pay more attention to. Because there is no way to control central heating. Whether we are at home or not, the heating is on. So the more resources are used, the higher the price will naturally be.

When there is no one at home, you can turn off the natural heating, which will reduce the resources used and naturally lower the cost.

Charge standard for central heating

What is the charging standard for central heating? Is central heating expensive?

In fact, there are regulations in the country at present, and there is no unified standard for the time being. Because of the different economic development in different places, the government's investment and charging standards are not the same.

According to the relevant national laws and regulations, the Ministry of Construction, the Ministry of Finance and other eight departments issued a notice to reform the current charging method by area, and gradually implement household metering and charging according to heat consumption to balance the interests of both supply and demand.

However, it is difficult to charge for central heating according to household heat consumption. At present, the charge for civil central heating in most central heating areas is about 20- 1 level in 30 yuan. The cost of commercial heating is about 25-40 yuan.

In addition, the different fuels used will also affect the price of heating. Some fuels are expensive, so the cost of heating is naturally higher. On the contrary, some fuels are relatively cheap, so the price of heating will be reduced accordingly. The price of civil floor heating in most areas is one square meter in 24 yuan.
