How to solve the problem that the end of the radiator is not hot, and the solution to the end of the

The reason why the end of the heating is not hot.

In our home environment, the main reason for the lack of heating at the end is the use of inappropriate heating installation methods, mainly in the following two ways:

1. Radiator series mode.

The so-called radiator series connection means that the water outlet of the first radiator is connected to the water inlet of the second radiator, and so on, until the last radiator outlet is connected to the return pipe.

This results in a single-tube series pattern. In this mode, because the radiator at the front end has hot water passing through first, it is very hot, and the second radiator is connected to the water after the first radiator dissipates heat, so the temperature is not as hot as the first radiator, and so on, until the end radiator becomes cold. Moreover, this series connection method has a long single-pipe pipeline, great water flow resistance, and slow circulating flow, which also aggravates the temperature reduction of the subsequent radiator.

Therefore, the radiators installed in this series mode at home are easy to cause the problem of not heating at the end.

2. Double-tube parallel programming.

The so-called double-pipe parallel connection is that there are two pipes for one supply and one return, and the inlet and outlet of the radiator are connected to the water supply pipe and the return pipe in turn, and all the radiators are connected in this way. In this mode, the hot water must also enter the first radiator first, and then enter the subsequent radiator, the water circulation is not a problem, however, after the hot water enters the first radiator, it will quickly flow out into the return pipe, and the rear radiator is in turn, obviously the front radiator water circulation.

To circulate faster than the radiator at the back, the total return pipe is so large, which will inevitably cause the temperature of the radiator to be lower the further back it goes, until the end is not hot.

The above two heating installation methods are the main reason for the end not to be hot, of course, there are other reasons that cause individual radiators not to be hot, if it happens to be the end, we can not deal with it according to the end of the situation that is not hot, or need to investigate the specific reasons. In general, in general, as long as the end is found not to be hot, it is basically the end that is not hot caused by the above two conditions.

If the heating is not only not solved, it will be difficult to solve the emotions when it encounters emotions? Do you generally check those heating rods for problems?

It may be that the pressure in the tube at the end is relatively small, so there is no heat; It is possible that the water cannot be circulated due to air blockage, so it is not hot. Solution: The former can be adjusted by a thermal unit or a circulating device on the main pipe to lift the circulation; The latter opens the exhaust valve on the radiator until the water flows out of it and then closes the valve.

Copper-aluminum composite radiator is a new type of high-efficiency and energy-saving heating radiator that makes copper tubes and aluminum wing profiles into heat dissipation components with precision pressurization process. It is a new product promoted by the state and a replacement product of the traditional cast iron radiator. The heat dissipation method is mainly convection.

The shape is noble and elegant, the heat dissipation performance is excellent, the pressure bearing capacity is high, the heat medium flows in the copper tube, and does not come into direct contact with the aluminum, therefore, the service life is longer.

The radiator is installed in the wrong way of water inlet, the radiator or pipe is blocked, the valve or temperature control valve is not fully opened, the number of pieces is insufficient, and the air is blocked. 1. The radiator is installed in the wrong way: contact the radiator installation company for reinstallation.

2. Radiator or pipe blockage: contact a professional radiator cleaning company or property to clean the heating system at home. <

The radiator is installed in the wrong way of water intake, the radiator or pipe is blocked, the valve or temperature control valve is not fully opened, the design is unreasonable, the number of pieces is insufficient, and the air is blocked.

1. The radiator is installed in the wrong way: contact the radiator installation company for reinstallation.

2. Radiator or pipe blockage: contact a professional radiator cleaning company or property to clean the heating system at home.

3. The valves or temperature control valves are not all opened: check the radiator valves of each branch on the heating pipeline to ensure that all are opened.

4. The design is unreasonable and the number of pieces is insufficient: replace the thickened curtains or replace the radiators with a larger heat dissipation.

5. Air blockage: Open the exhaust valve of the radiator until water flows out, repeat many times to ensure that the gas in the radiator is emptied.

<>1. To judge whether there is a problem with heating, first judge whether the outdoor heating pipe is hot, if it is not hot, it is a problem with heating, and it is necessary to test the pipeline of the heating system to check whether there is a valve that is not opened or the heating pressure is insufficient, if the pressure is insufficient, a circulating pump can be installed to improve the circulation speed of hot water, so as to achieve the ideal heating effect. 2. Check whether the valve of the inlet and outlet water in the room is open. 3. Check whether there is any debris blockage in the pipeline, and you can ask professional personnel to repair it.

4. There may be gas in the pipe, at this time, it is necessary to open the air release valve on the water separator for air release, and wait until there is hot water to release and then close.

Radiators are half hot and half not hot? In this way, the temperature can easily rise, which is simple and practical.

The radiator part is not hot and the use of the sound of running water, the reason for this failure is the accumulation of gas in the radiator, you need to open the air release valve to release the air, close the water inlet when exhausting, according to the water inlet and return route, open the exhaust valve on the side of the radiator in turn, wait for the exhaust valve to remove all the air, flow out of the stable water flow and close the valve.

One or more groups of radiators are not hot, and other radiators are running well, this situation is mainly due to the uneven water flow of each group of radiators, and the water inlet valve of each group of radiators needs to be adjusted.

If the heating has never been altered in your home, or the heating effect has been satisfactory in previous years, but the surrounding neighbors have modified the heating or installed other equipment on the heating system, then the problem may appear in the neighbors, and the local hydraulic balance of the heating system may be destroyed.

1: Open the air release valve on the side of the radiator and slowly drain the accumulated air until the hot water is released.

2: First of all, make sure that the radiator valve of your home has been opened, and ask the neighbor upstairs and downstairs if it is open.

3: For owners who have not changed the heating, the solution is: find a thermal power company.

4: Replace new products such as sand-free cast iron radiator or steel elliptical radiator in the inner cavity.

5: The radiator is not hot on the situation that the installation may not be in place, or it may be improper use or poor maintenance in the later stage, if there is a problem with the installation, you should find a radiator installation company for post-service, if it is improper use or poor maintenance, you can solve it according to the relevant instructions of the radiator, or find a professional HVAC company for service.

The decoration foreman explained the difference between heating series and parallel connection and the solution of heating not hot, hoping to help you in decoration.

Reason why the heating is not hot 1: Heating system reason. Residents on the top floor close the cut-off door completely or partially, causing the circuit to be blocked or interrupted.

Another factor is the blockage of the heating system, some heating systems that have been in operation for many years but have not received the necessary maintenance and maintenance, such as blockage, leakage and other phenomena affect the heating effect of the whole system. There are also some residential areas where the original design of the heat supply and heating area do not match, forming a "small horse-drawn cart", and the above problems should be solved by the property management department.

Reason 2 for the heating not to be hot: The heating itself is the cause. Now most residents use the old-fashioned cast iron heater, most of this heating is old, to rely on the heating cover to dress up, the decorative effect is improved, the quality of life is reduced, "beautiful and frozen people", some residents simply open the heating cover in winter, despite this, the heat dissipation effect is still greatly reduced, to fundamentally heat up, the best way is to use the new heating without cover.

Reason 3 for the heating not to be hot: The heating has the sound of water. The main focus is on the top-in and bottom-out installation method, because there is gas inside the radiator that cannot be discharged.

The solution is to close the water supply valve of the radiator, open the discharge valve, discharge the gas inside the radiator, close the exhaust valve, and open the water supply valve. If it cannot be ruled out, check whether the flow rate of the system is too low or the gas content of the circulating water of the system is too large.

The radiator does not need to be equipped with any temperature control valve, think about it, what is the harm of the radiator being able to have a high temperature. Just take it off.
