What does district central heating mean

A form of centralized group heating. 1. Central heating refers to a form of centralized group heating. Generally, it is charged per square meter (building area) in a heating season, and for the northern region, the weather is relatively cold, and the heating time is long, so central heating should save money.

2. From the aspect of energy utilization, central heating is large at one time, high operating costs, whether it is needed or not, the heating is always heated all day, and the temperature is uneven due to different floors.

3. Central heating has a power pump in the system heating, that is, a very small heating system has an axial flow pump to power the circulating water. In the 'earth heating' of the home, it is generally recycled by artesian flow. The inlet of the radiator is higher than the outlet of the heating furnace, and the heated hot water is relatively light and 'rises' into the radiator, and the circulating water in the radiator becomes cooler after heat exchange, becomes heavier, and flows back to the heating furnace.

District central heating is relative to municipal heating, the community self-built heat source equipment for the residents of the community heating, common heat source equipment air energy heat pump.

Electric boilers, gas boilers, etc.

Because the heating system is small and located in the community, problems can be found and dealt with in time, and the heating cost will be relatively low when the heating equipment is reasonably selected, and even cheaper than municipal heating.

However, in some communities, central heating is not 24-hour heating.

Radiators for central heating.

Buying tips. 1. When buying a radiator, first of all, you should understand the water quality and heating system of the community, because most of the residents use steel radiators, and the oxygen content of the water quality is not too high when using this radiator, but it is difficult to ensure the oxygen content of the water quality during central heating, so when choosing a radiator, you need to explain the specific situation of the heating environment to the manufacturer.

2. When purchasing radiators, it should be ensured that the radiator material used in each room is the same, so as to avoid electrochemical reactions between radiators of different materials due to the different materials used in each room, so that the radiators will corrode.

3. From the point of view of practicality, you can choose steel radiators, because steel radiators are more durable and safer to use, and you can also choose copper-aluminum composite radiators, which have better corrosion resistance.

The pressure standard for central heating is generally as follows:

The pressure of central heating is different on different floors. Generally speaking, in order to ensure the normal operation of the heating system, the central heating pressure should not be less than, but not exceeded.

If the pressure is too high, it can pose a safety hazard to the heating system.

If the pressure is too low, it will cause poor circulation in the heating system.

Generally speaking, the state stipulates that the indoor heating temperature is 80, the return water is 60, and the room temperature is 18, however, according to the large temperature difference between different regions in the north and south, the heating temperature in different regions fluctuates accordingly.

However, the final household pressure should not be lower, and if it is below this, it will lead to poor circulation. If the owner uses central heating, he should always pay attention to the payment notice and then pay the heating fee clearly in advance so that he can easily enjoy the heating during the heating period.

Precautions for central heating:

1. Pay the heating fee in advance and handle the suspension and resumption of the businessPay the heating fee and handle the suspension and resumption of the business in a timely manner, and pay the heating fee on time and in full, so as to enjoy the heating warmth with peace of mind in the winter heating season.

In order to avoid crowding, long queues, and long waiting times during peak periods, users should pay attention to the payment notice and pay the heating fee in advance to avoid inconvenience.

2. During the pressure test period, ensure that the heating company will test the pipe network in advance before heating, and post a notice on the door of the corridor before the pressure test of the pipe network, and notify the residents of the time of the water test in advance, on the day of the water test.

There should be someone left in the user's home, and the radiator should be paid attention to when testing the water.

Whether there is water leakage at the interface of the heating pipe and the valve of the heating pipe due to aging, loosening and other reasons.

3. Regarding the things that need to be paid attention to by the users who apply for the suspension of supply, the heat users who apply for the suspension of supply should promptly notify the heating company to close the valve and do not suppress the water test, otherwise the water stored in the heating pipes and radiators will freeze and crack the heating pipes and radiators after freezing, which will bring unnecessary losses to you and others.

The heat of central heating in the north comes from the local power plant or thermal power plant, the ordinary coal-fired boiler is seriously polluted, the cost of the gas boiler is too high, at least several times that of the central heating, the state prohibits the heating of small boilers, and the conditions are included in the central heating network.

The best way to do this is to use an air conditioner for heating, which is now cheaper and uses much less electricity than before.

You can use the gas wall-hung boiler at home to heat, which is more economical, and it can also better control the temperature and room selection.

with air conditioning. The power of the air conditioner is not very large, and the air conditioner can also make heating.

Why doesn't the community have central heating? There is no central heating in the small Yuhuowan area should be the old community, and now the new community should be depressed is centralized supply, the old community, his infrastructure department does not meet the conditions to improve it, so he can not be centrally heated, put the new chain of the Bi community can.
