What should I do if the radiator at home is not hot?

First, the radiator has not been cleaned for many years, and there is too much scale.

If your radiators have been used for many years and are not cleaned regularly, be careful! The radiator will produce some scale impurities during long-term use, and if it is not cleaned regularly, it will cause uneven heating and even water leakage of the radiator. If the heating problem is caused by this reason, the user can invite professional after-sales maintenance personnel to conduct regular inspections, pipe filtration and pipe cleaning, so that the phenomenon of uneven heating can be quickly solved.

Second, the radiator pipe installation is wrong.

In order to save more money, some users will choose to install radiators by themselves, but because they are not professionals, they sometimes feel that the access is wrong, resulting in the reverse connection of the water supply and return pipes, and the normal circulation line cannot be formed, resulting in the phenomenon of half hot and half not hot. Therefore, in order to face this problem, consumers must choose a professional installation team and a professional radiator brand to avoid such problems.

3. There is too much gas in the radiator pipe.

Too much gas in the radiator duct is also one of the reasons why the uneven heating can only be locally heated. If this is the case, the user can open the air vent valve and release the remaining gas in the pipeline.

Fourth, the heating pressure is insufficient, and the phenomenon of "small horses and carts" appears.

The reason for the formation of such a phenomenon in some places is that the original heating volume and heating area of the community do not match, resulting in the phenomenon of system imbalance and insufficient heating pressure, which is very easy to form the phenomenon of downstairs heating, upstairs is not hot, and the next door is hot but not hot. If this is really the reason, it is recommended that you contact a professional radiator company and do not do it yourself, so as not to cause greater losses.

The phenomenon of uneven heating of radiators is mainly due to the above four points, and we must analyze the specific problems when we encounter problems, and do not easily do it ourselves. Once the radiator is not hot, you need to find a professional radiator manufacturer for consultation and maintenance, and it is not recommended that the user repair it privately.

There are several radiator problems, you can rule them out, first see if the heating water temperature is not enough, if it is not a problem of water temperature and water pressure, it is a problem with the pipeline, check whether the inlet and outlet valves are opened, if the valve is also open. Just check whether it is blocked by the air, generally speaking, it is enough to release the air through the exhaust valve. If it doesn't work, just ask the master to come to see it, Rubens heating hopes to help you.

Try venting the radiator first.

There is air in the heater, which causes the hot water to not fully fill the radiator, resulting in a decrease in thermal efficiency and the radiator is not hot. So just release the gas, here are the specific steps:

Tools required: Aper, towels.

1. Put the towel in the place of the exhaust valve to prevent the floor from being soiled when the water comes out.

2. Twist the valve counterclockwise with a word change cone until the air is out.

3. When the gas inside is discharged, the valve will come out of the water, and then the valve can be screwed dead.

4. Tighten the valve clockwise.

5. Wipe the excess water with a towel.

6. This is done, after the air is emptied, the radiator will be hot, and the effect is good.

1. What should I do if the radiator at home is not hot?

1. If the radiator and the pipe are not hot, if this happens, there are generally two reasons, it may be that the main valve of the corridor is not opened normally, and you need to contact the property or heating company to check, if they check and find that it is open, or the supervisor of the corridor should be checked to see if the pipeline is blocked. If the supervisor is blocked, the heating company or the property arranges professionals to repair it to avoid greater losses.

2. If only the radiator radiator is not hot. There are generally four reasons for this:

The valve of the radiator is closed.

Judging that the valve is not hot when closed, the heating pipe is hot and touches the radiator without temperature, that is, the valve is not opened, select the category of the valve, the valve is normally opened counterclockwise, closed clockwise, after opening, it will be found that there is a sound of water flow, and slowly the radiator body will also appear heated.

A large amount of gas was stored in the radiator pipe and was not exhausted in time.

If the valve is opened and the temperature of the radiator is uneven, or it is not very hot, the heating will be tested in the early stage of heating every year, and it will not be too hot. First turn off the inlet and return valve of the non-hot radiator, prepare a flathead screwdriver to facilitate the filling of water, and a rag to prevent a large amount of water from spraying out and affecting the appearance of the wall, and then use a flathead screwdriver to screw the exhaust valve counterclockwise, listen carefully to whether there is a sound of gas discharge, after there is no gas only water flowing out, tighten the exhaust valve clockwise, and then open the inlet and return valve, the valve radiator will start to heat up. If this situation still occurs later, you need to repeat the operation several times.

The radiator is clogged after a long period of use.

Due to the long-term use of the radiator and the lack of cleaning, there will be sediment or other impurities in the pipe, which will cause the radiator to be blocked, and the scale in the hot water will continue to adhere to the radiator, which will cause many impurities in the radiator. When they accumulate in one place for a long time, they can become clogged and cause poor water circulation. If there is a blockage, you need to remove it and flush it with high-pressure water, and then install it, you can do it, if it is still not hot after high-pressure washing, then you need to check whether the pipe is also blocked, if the pipe is not affected, you need to replace the new radiator.

1. The radiators and pipes are not hot。If this happens, there are generally two reasons, either the heating valve is turned off, or the pipe is blocked or broken. First of all, you can go to the valve position 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 blocked or broken, it needs to be repaired by a professional immediately to prevent serious consequences.

2. Only the radiator is not hot。There are generally three reasons for this situation: the first is that the temperature control valve of the radiator is closed, the second is that the radiator is not vented in time, and the third is that there is a foreign object in the middle of the radiator.

These three situations need to be investigated one by one. If the temperature control valve is not opened, you can open the temperature control valve counterclockwise and then observe whether the radiator is hot. If the radiator is not vented in time, you can dispose of it yourself.

First close the heating valve at home, prepare the water basin to facilitate the connection of water, and then use the screw to send the gas release valve, listen carefully to whether there is the sound of gas discharge, and stop twisting if there is. After the gas is discharged, there will be water flowing out slowly, observe whether the water flow is stable, if it is stable, you can close the release valve, observe whether the radiator becomes hot, if not, repeat the above steps, and slowly the heating will heat up. This is the most common failure symptom and there is no need to panic.

If the above two situations are ruled out, it should be that there is a foreign object in the radiator that causes blockage, which requires a professional to dredge, and do not deal with it blindly, which will cause serious consequences.

3. Only some radiators do not heat up. If a group of radiators is not hot, it may be because the heating resistance is uneven, so that the water flow is also large and small, and then you need to adjust the water inlet valve of each radiator to solve the problem. Because the heating system is related, it may also be because of the problem of the radiator of the upstairs and downstairs neighbors, you can consult them, if everyone has the same problem, you can find a professional to carry out unified maintenance.

There is also a situation that is half hot and half not hot, the reason for this imagination is that there is a lot of excess air in the radiator or pipe, as long as you follow the previous exhaust steps, you can restore the heating after a few more times.

Most of the radiator problems are here, if they still can't be repaired after these troubleshooting, you need to contact professional maintenance personnel for repair.

The design of the pipe diameter is unreasonable, and the pipe diameter of some parts is too thin;

Some parts have too much resistance, such as the valve cannot be fully opened;

There is debris blocking in the system;

The air in the system cannot be removed cleanly due to incorrect or insufficient pipeline slope direction;

Some users have too few heating groups and insufficient heat dissipation;

The water supply and return pipes of the indoor system are connected to the outdoor water supply and return pipes in reverse directions, or the riser pipe is incorrectly connected with the main pipe.

The radiator is half hot and half not hot, there is a sound of water in the radiator, or the temperature of the radiator is not as high as someone else's?

Causes and solutions for not heating: This situation is because there is air in the radiator group, and the exhaust valve needs to be opened to release the air until there is water flowing out. The method of deflating, on the upper side of the radiator, the toilet heater is at the top, there is a deflation valve that can be adjusted with a screwdriver, rotate counterclockwise, release the air in the heating, and the heating can become hot, and it needs to be deflated many times according to the situation until it is exhausted.

Note: Never screw large bolts below the heater near the ground.

The radiator at home is not hot, but the pipe is a little warm?

Causes and solutions of no heat: This situation may be that in order to prevent the radiator from corroding, the group valves of each group of heating are closed before the end of the heating of the previous year, so as to prevent the air from entering the heating and making the heating rust and rot, and then the sub-valves of each group of heating need to be opened.

The heating temperature in the home is different, some are very hot and some are not?

Causes and solutions for not heating: This situation occurs, mainly because the flow of hot water in each heating is uneven or the internal resistance distribution is uneven, and the water inlet valve of each radiator needs to be adjusted separately.

Radiators and pipes at home are not hot?

Causes and solutions for not heating: This situation may be that the main valve of the heating is closed, and the main valve is generally in the inspection well of the unit staircase, we only need to check the supply and return valves to confirm that they are opened.

All the heating in the house is close to the heat of the entrance door, and the farther away from the entrance door, the lower the temperature?

Causes and solutions for no heat: turn off a group of heating, all the heating will not be hot, this situation is caused by the radiator group in series, for example, the water temperature of the entrance pipe is 75 degrees, after the first group of heating, it becomes 65 degrees, and then the temperature may be reduced to 45 degrees after entering the second group, and then the temperature will be lower, and the radiator will definitely not be hot. In this case, a professional repairer should be contacted as soon as possible.

Winter is a very cold season, in most areas of the north will be central heating, in fact, the most important heating equipment for central heating is the radiator, sometimes the radiator in the home will not be hot, this is often a very serious problem with the radiator, so we should first find the reason, so, what to do if a single radiator is not hot? What are the reasons and solutions for radiators not to heat up?

It is understood that it may be that the heating pressure is not enough, and the water circulation is not smooth. Most of the reason is that the filter screen is blocked, the main reason is that the radiator of each owner's house is used last time, and the stolen goods in it are flushed out and circulated to the filter screen, as long as the filter is washed 2 to 3 times, it will be much better when it is used again next year. The filter is the goalkeeper of our radiators, and if there is no it, our heating will be blocked in a few days, and it will be troublesome.

Causes and solutions for radiators not to heat up.

1. The valve or temperature control valve is not fully opened.

Specific performance: some radiators are hot, some are not.

Solution: Check the radiator valves on each branch of the heating pipe to make sure all are open.

2. Air congestion. Specific performance: the radiator appears in the lower half of the heat, the upper half is not hot or the first few groups of heat, the back of the radiator is not hot, this situation often appears in the early stage of heating, the heating system of the pipe and the radiator will accumulate some of the residual air in the original pipeline system, resulting in the phenomenon of blocking the hot water circulation, in which the end of the pipe user is more prominent.

Solution: Open the exhaust valve of the radiator until water flows out, repeat several times to ensure that the gas in the radiator is emptied.

3. The radiator is installed in the wrong way.

Specific performance: the radiator is installed in and out, and the water will flow directly from the main pipe below, only the main pipe below is hot, and the radiator above is not hot, or the radiator in and out is installed in and out, and some pieces will not be hot, etc.

Solution: Contact the radiator installation company to reinstall it.

4. The design is unreasonable and the number of pieces is insufficient.

Specific performance: all the radiators at home are heated normally, but the room temperature always does not meet the requirements. This is due to the insufficient number of radiators designed or installed.

Solution: Replace thicker curtains or radiators with more heat dissipation.

5. Blockage of radiators or pipes.

Specific performance: the heating effect of the radiator is lower than in previous years, and even the radiator is not hot, and the reason for the air blockage and water inlet temperature can be basically determined to be the radiator or pipe blockage, especially for users who have not installed filters.

Solution: Contact a professional radiator cleaning company or property to clean the heating system in your home.
