After the heating main is repaired, what happens if the heating is not hot

Radiator after repairing a leaky heating pipe.

There are three cases of not being hot.

1.There are several sets of radiators that are hot and several sets of radiators that are not hot.

Cause: This situation may be that when the pipeline is repaired, the grouping valve of the heating is closed, resulting in several groups of radiators being hot and several groups of radiators not being hot.

Solution: Find the sub-valves of each group of radiators and open them one by one.

2.A set of radiators is half hot and generally not hot.

Reason for the accident: This situation is because there is air in the radiator group, and the solution: open the radiator release valve to release the air until there is water flowing out.

The method of deflation of radiators, generally the deflation valve is on the upper side of the radiator, and the bathroom radiator is at the top, (the deflation valve is shown in the figure below), manually adjust the deflation valve, rotate counterclockwise, and release the air in the radiator, that is, it is necessary to deflate many times according to the situation until it is exhausted; Automatic bleed valve.

It's relatively simple, just just give up.

3.The heating temperature in the home is different, some are high and some are low.

Reason for the accident: This situation is mainly caused by the water in each group of radiators.

Caused by uneven flow or uneven distribution of internal resistance.

Solution: Adjust the water inlet valve of each radiator separately, if it still does not work after commissioning, it may be that there is a blockage in the heating that is not hot, and professional maintenance personnel are needed to dredge.

Common fault 1: The heating is not hot as a whole. Exclusion method: Open the inlet and return valves.

Common fault 2: The heating is not hot.

Exclusion method: There may be gas in the heater, and it needs to be deflated.

Method 1: Close the water inlet valve first, open the air bleed valve to exhaust, and close the air release valve when there is water overflow.

Method 2: Close the water inlet valve 3 4, then close the return valve, release the valve to exhaust, close the air release valve when there is water overflow, and finally open the return valve and the water inlet valve.

Exclusion method: low inlet water temperature, increase inlet water temperature.

If the heating is not hot, find a warranty from the heating company or contact the property.

When citizens encounter the problem of heating not heating in winter, they can take three steps to protect their rights and complain

1. Directly complain to the boiler room or heat exchange station in the jurisdiction, which is the most direct and fastest way.

2. If the boiler room or heat exchange station in the jurisdiction cannot solve the problem, or cannot give you a satisfactory answer, you can complain to the superior authority of the boiler room or heat exchange station (heating company or heating company), and it will guide and supervise the solution of the problem.

3. After the above process, if the user's problem is still not solved or has not received a satisfactory answer, he can complain to the district heating management office.

If the other residents of the whole building can use the heating normally, but the heating pipe of their own home is not hot, there are three situations to consider:

1. Due to negligence, the heating valve of your home is not opened or not opened in place;

2. There is gas in the pipeline;

3. The filter is blocked or the floor heating pipe is blocked. The above situations belong to your own home and are not hot, and it has nothing to do with others.

It is recommended to check whether the heating valve is turned on in your home first, and if the valve is opened normally, you can contact the property to check.

Possible reasons why the valve is open and the heating is not hot:

1. Only open the return valve, the inlet valve is not opened or the inlet valve is opened, and the return valve is not opened;

2. Radiators.

No venting is carried out;

3. The pipeline is blocked, and the hot water does not flow;

4. There is no hot water.

First of all, when the radiator is not hot, let's not panic. First confirm whether the valves of the heating equipment have been fully opened, and then check whether the temperature setting is reasonable, if the temperature setting is not reasonable, the heating operation effect will be greatly reduced.

1) It is recommended that the boiler outlet temperature be set at 55 5°C for the floor heating system, and the boiler outlet temperature setting can be reduced under the condition of maintaining indoor comfort, which can achieve a certain energy-saving effect;

2) The radiator system recommends that the boiler outlet temperature be set at 65 5°C, and the boiler outlet temperature setting should be adjusted according to the ambient temperature;

3) The thermostat is recommended to set the room temperature to 20 2 ° C.

On the other hand, we also need to check whether there is any obstruction around the radiator, house decoration or other facilities, objects blocking the heating, or piling up debris on the radiator, and the air convection around the radiator is obstructed, which will also affect the heat dissipation effect. Of course, there is also room insulation also affects the heat dissipation effect of radiators, old buildings, doors and windows are not closed strictly, or there is no insulation layer on the exterior wall of the building, as well as the top floor, side rooms are more heat consumption. When turning on the heating, the indoor insulation should be done well, and the doors and windows should be closed to reduce heat loss.

If you find that the radiator at home is hot and cold, or the heat and cold are uneven. We need to check whether the radiator has the phenomenon of "gas blockage", when there is a group of radiators that are not hot or half of the radiators are not hot, first check whether the radiator valve is open or fully open. If the radiator valves are all open, the radiator may have an "air blockage" and the radiator needs to be vented.

Exhaust method: Find the air release valve on the other side of the radiator valve, and use a flathead screwdriver to turn the air release valve counterclockwise until water comes out of the release valve.

There is also a possibility that the radiator is not evenly heated due to poor heating circulation or foreign body blockage. The radiator is hot above, not hot below or not hot at the top, hot below, it is very likely that the heating circulation is not good or the foreign body is blocked, you need to debug the water inlet and return valves, and contact professionals to come to the door for maintenance.

There is gas in it, and the gas is not discharged, and the radiator is normally opened, but if there is gas in it, the water cannot be circulated.

In this case, the first thing to consider is whether there is air in the heating pipe, you can open the waterproof valve of the radiator, release the water, and discharge the air.

There is air in the radiator that causes it to be not hot, which is generally manifested as a group of radiators that are not hot or the radiators are hot and cold at the same time. It is only necessary to exhaust the gas in the heating and complete the hot water circulation inside. A problem with the radiator valve is causing the radiator to not heat up.

Check that the radiator valve is open. For users who use heating for the first time, many have not opened the valve of the radiator, and the valve of the radiator is generally open counterclockwise and closed clockwise, do not screw it backwards.

In this case, if the existing radiator is hot, and some of the radiators are not hot, it is likely that the pipeline circulation is not good, and the exhaust valve of the radiator is opened lightly, and the exhaust valve is closed when there is water flowing out. If it doesn't work, call the heating company**.

When the heating is not hot, you need to find the problem.

Close the inlet and return valves of the heater: if the gas is not smooth, the water circulation will deteriorate and the natural heating will not heat up.

Preparation: Clean the filter to prevent clogging.

Install a hot water circulation pump: It can increase the speed of the return water, and the temperature will also rise.

Hello, I'm glad to answer for you, the reason why the heating pipe is not hot is that the radiator has gas, the heating has been used for a long time, there will be some gas in the middle, if it is a group of punch radiators, there are a few pieces of hot and a few pieces are not hot, you need to open the manual exhaust valve on the radiator until there are no bubbles in the water flowing out.

The second reason why the heating pipe is not hot is that the radiator is installed incorrectly, and you need to find the HVAC company that installed the radiator to reinstall or replace the radiator. Reason 3: The inlet and return pipes of the radiator are reversed, and the socks company that rents the radiator is asked to adjust it.

The radiator is not hot at all.

There are two reasons why the radiator is not hot, either the heating valve is closed, or the pipe is blocked or broken, first of all, you can go to the valve to check whether the valve is closed, if you can't find the valve, you can seek the property personnel to check. If it is a plug or broken lie, it is necessary to immediately call a professional to repair it to prevent serious consequences.

Hello, dear The question you asked, here is the answer to the following for you: What are the reasons why the radiator is not hot? One of the reasons:

When maintenance workers go to residents' homes to exhaust and debug, many people will find that the water flowing out of the heating pipe is black and contains a lot of impurities, and it will take more than half an hour for the water to flow out. These impurities, all caused by fine sand or rust in the pipes, accumulate in the pipes and affect the hot water circulation of the heating system. Therefore, the impurities in the pipes should be flushed out by water at the beginning of heating.

Reason 2: The water supply and return pipes are reversed, and some users connect the water supply and return pipes when they privately connect the heating pipes, or the developers connect the water supply and return pipes in the reverse when building houses, resulting in hot water and cold water "top cows", and the hot water circulation cannot be realized, and the heating is not hot, which requires re-installation of heating facilities. Reason 3:

When the heating piping system in the home of a resident is not running for a long time, there is often gas in it, which will lead to poor circulation of hot water and the radiator will not be hot. To solve this problem, just open the air running valve on the radiator, release the gas in the pipe, and the hot water will flow over, and the radiator will heat up. In addition, some residents forget to open the outlet valve under the pipe, and the hot water cannot be circulated, so do not forget to open the outlet valve when the heating starts.

Summary: heat source problems, pipe installation problems (resulting in poor pressure circulation), radiator mask liquid base problems (blockage, insufficient number of pieces, valve is not well adjusted). Bury to find the corresponding phenomenon, and then find the cause according to the phenomenon that the radiator is not hot, and finally find a countermeasure to solve it.

Dear, I'm glad to answer for you, how to answer that the radiator is not hot after repairing the main pipe; 1: The heating is not hot overall. Exclusion Method:

Open the inlet and return valves. Common fault 2: The heating is not hot.

Exclusion method: There may be gas in the heater, and it needs to be deflated. Method 1:

First, close the water inlet valve, open the air bleed valve to exhaust, and close the air release valve when there is water overflow. Method 2: Close the water inlet valve 3 4, then close the return valve, release the valve to exhaust, close the air release valve when there is water overflow, and finally open the return valve and the water inlet valve.

The heating line is not warm enough. Elimination method: low inlet water temperature, increase the inlet water indiscriminate temperature.

Water leaks from the inside of the inlet and return valves (in the direction of the heat).

The heating is not hot to find the property, the boiler room for heating in the area, and the heating company for maintenance.

1. If the heating in the public area is not hot, you can find the property first, and if the property does not care, you can complain directly to the heating company.

2. If the heating of your home is not hot, the general situation of the property is not important, you can call ** to the boiler room or heat exchange station responsible for heating in the area to complain, they can directly assign staff to solve the problem of heating is not hot after receiving the complaint.

3. If the boiler room or heat exchange station cannot solve this problem, then they can call the heating company of their superior to complain, and the heating company will assign a special person to supervise the solution of the problem after receiving the complaint.

Reasons why radiators are not hot

1. Air blockage, through observation, it is found that the temperature of some radiators in the home is low, this phenomenon is mainly due to the existence of air to prevent the circulation of hot water. Therefore, the user only needs to open the exhaust valve at one end of the radiator to exhaust the air inside. If there is a water spray, it means that the air has been discharged, and the exhaust valve can be tightened at this time, and it can be used normally.

2. The pressure is not enough, if the method in the first case does not work, it may also be that the pressure in the heating pipe is not enough, so that the hot water can not be effectively circulated. At this time, you can find a heating company to add a pressure pump to fully circulate the hot water, so as to achieve the effect of full heating.

3. The direction of the pipe is wrong, and there is also a possibility that the pipe direction of the radiator is reversed, so that the hot water and cold water cannot be automatically convection, resulting in the heating is not hot. This kind of problem requires changing the pipe to an up-in-down out.

<> "1. How to solve the problem that the heating pipe is not hot.

1. If it is caused by the temperature control valve in the heating system not being opened, the temperature control valve should be slowly opened. If you want to open the temperature control valve, you should generally rotate it in a counterclockwise direction, and if you want to close it a little smaller, you should rotate it in a clockwise direction, and you must not reverse the direction.

2. If the hot water in the pipe is not circulated smoothly because there is residual air in the heating pipe, the exhaust valve on the radiator should be opened for degassing, so that the air inside can be discharged, and it can be closed after the discharge is clean.

3. If the radiator is blocked because there is a lot of limescale, iron filings and other dirt accumulated inside the radiator, you should ask a professional to clean the entire heating system to let the blockage be dredged.

4. If it is caused by the wrong installation of the radiator by the construction personnel when installing the radiator and the connection mode of disturbing the envy in and out of the radiator, you should ask a professional to reinstall the radiator at the door, or directly replace the radiator with a new one.

Note: There are many reasons why the radiator is not hot, the reasons are different, and the solutions will be different.

Second, what are the key points of using radiators?

1. In order to ensure the heating effect of the radiator, the radiator must have enough space for heat dissipation, for this reason, it is recommended that you do not place oversized furniture around the radiator, and the radiator itself should keep a distance of about five centimeters from the surrounding furniture and walls.

2. If the area of the house is relatively large and the number of rooms is relatively large, the radiator in the room that has not been used for a long time can be turned off, or the temperature can be lowered, which can not only reduce the heating area, but also save energy.
