What should I do if the heating in my home doesn t work? Is there any way to improve the heating in

1. The heating needs to be deflated.

In the early stage of heating, a large amount of air also enters the heating pipe at the same time during the water supply process, and if it cannot be discharged in time, it will accumulate in the pipe, which will cause the heating to be not hot.

Solution. At the back of each radiator is a manual air release valve that unscrews the rotating shaft to drain the air until the flow is smooth. If the screws of the heating air vent valve have rusted to death, do not twist it rashly, so as not to break the air vent valve and cause the heating hot water to spray out, and ask professional plumbing personnel to come to repair.

At the same time, residents living in high-rise buildings should regularly check the heat of the heating, and if there is any uneven heat, they should exhaust the air in time.

2. The pipeline system is blocked and needs to be cleaned.

If the indoor temperature was 20 degrees last year, the indoor temperature was reduced under the condition that the gas supply to the boiler room and the heat exchange station was working normally. Then, it can be judged step by step that the wall blockage of this radiator is more serious and needs to be cleaned by professionals.

Solution. Normally, geothermal users should clean their pipes every two years, and older heating users should have their pipes professionally cleaned every seven to eight years.

3. The heating needs to be replaced if it is "overdue".

The reason why the heating is not hot may also be that the heating is used for a long time, the inner wall is scaled, and the thermal resistance increases, resulting in poor water flow and the temperature cannot go up. The service life of the old-fashioned radiator is about 20 years, and the service life of the new radiator is about seven or eight years, and 10 years has basically reached the limit.

Solution. Residents should replace their heating with new ones before they reach the maximum age limit.

4. Human causes.

There are also some reasons why the heating is not hot due to the user's artificiality, such as overloading more radiators, installing water drain valves without permission, installing water circulation pumps, etc. In fact, the act of adding pumps without permission is resolutely prohibited in the heating management regulations and is illegal.

The radiator is not hot and the solution.

1. The radiator at home is not hot, but the pipe has a certain temperature.

This situation could be that after the heating of the previous year ended, you turned off the main valve in the room due to a long time away or other reasons. You need to open the valve in the house, and then check the inlet and outlet valves of each group of heaters, and make sure that they are all open, so that you can wait for a while to see if the pipes and radiators have temperature.

2. The temperature of the radiator is not as high as that of other people's homes.

This may be the case that there is air in the radiator group, which is causing poor water flow. At this point, you need to open the exhaust valve to vent until there is a flow of water. The method of deflation, on the upper side of the radiator, the toilet heater is at the top, there is a deflation valve that can be opened and adjusted (the opening method is not the same), after opening, the air in the radiator pipe and the radiator is released, the water flow is smooth, the radiator is hot, and it needs to be deflated many times according to the situation until it is exhausted.

Note: The exhaust valve is all arranged on the upper part of the radiator, and the one close to the ground will not be the exhaust valve.

3. The radiator at home is very hot, but the temperature in the house is not high.

There are two possibilities in this situation: a house is not an energy-efficient building, there is no external wall insulation, or the doors and windows are leaking, the indoor temperature will not rise, and window leakage is a common problem. You can keep it warm with some seals; If there is a gap between the outer frame and the wall, the crack is large, you need to fill the polyurethane styrofoam first and then use glass glue, if the gap is small, you can directly use glass glue to seal.

The second possibility is that the number of radiators installed in the room is insufficient. The quality of the products of different manufacturers is not the same, the heat dissipation effect is not the same, and the construction personnel install with previous experience, without considering the actual situation of each family, resulting in the final number of radiators is not enough. At this point, it is necessary to ask a professional to help redesign the number of radiator groups.

1. The first thing you need to do is to find a more professional installer when installing the heating, and give a reasonable heating design according to the situation of your own home, including the number of radiator groups, the diameter and direction of the heating pipes, etc., the connection between the heating pipes and the radiator groups, in addition to the air heating, the rest need to be connected to the pipes when the radiator groups go up and down, or down and down to make the heating hot water flow smoothly, and only when the hot water circulates and flows the heating can it be hot.

2. The radiators and pipes at home are not hot, this situation may be that the main valve of the heating is closed, the main valve is generally in the inspection well of the unit staircase, we only need to check the supply and return valves, and confirm that it is opened.

3. The heating at home is not hot, but the pipes are a little warm. In this case, in order to prevent the radiator from corroding, the grouped 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.

4. The radiator is half hot and half is not hot, there is a sound of water in the radiator, or the temperature of the radiator is not as high as that of someone else's. In this case, there is air in the radiator group, and the air valve needs to be opened to release the air until there is water flowing out. The method of deflation, 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.

5. The radiator at home is very hot, but the temperature in the house is not high. This situation may be that the power of the heating is too small, and now the home decoration has replaced the radiator group that was originally designed and calculated, but the quality of the newly installed heating construction personnel is uneven, and the specific situation of your home cannot be fully considered, so it may be possible to install less radiator group in your home, so you need to ask professionals to help and redesign the number of radiator groups.

6. The heating temperature at home is not the same, some are very hot and some are not. In this case, the main reason is that 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.

7. All the heating in the home is close to the heat of the door, the farther away from the door, the lower the temperature, turn off a group of heating, all the heating will not be hot, this situation is caused by the radiator group in series, you think, if the water temperature of the 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 final temperature will be lower, the radiator will definitely not be hot. In this case, find a heating installer as soon as possible, find him to solve it, and compensate you to modify the pipes.

What is the solution to the radiator not heating In fact, for the radiator is not hot, we should not blindly deal with it. The specific reasons why the 5 o'clock radiator is not hot are introduced to you above. And we should take different measures for different reasons.

For example, after we find that the radiator at home is not hot, you can follow the following steps to deal with it and eliminate the problem step by step. In this way, most of them can also solve the problem of not being hot.

Exhaust. After we found that the radiators at home were not hot, the first thing we did was to exhaust the radiators. And this is something we can do ourselves.

Because the exhaust valve of the radiator is basically on the left or right side of the radiator. Like today's radiators, they are basically installed with manual exhaust valves. We use a screwdriver or pliers to twist the exhaust valve, and of course, we have to prepare the tools to catch the water in advance.

The aim is to get the gas out of it. After that, the gas is drained, and clean hot water is discharged. At this time, if the hot water discharged is clean and pressurized, it means that the gas is discharged.

At this point, the exhaust is over.

Clean up the filter.

The radiator is not hot, the second step we need to do is to clean the filter. Like the radiators in our homes, they are generally installed with filters at the entrance of the house. Like today's commercial houses, there is generally a plumbing pipe well before entering the house, and a filter is installed in the plumbing pipe well.

We find the filter in our house, which is the pipe that comes into our house, and we close the valve. Use a wrench to remove the plug under the filter, and then remove the filter inside. At this time, we will find that the filter screen has been filled with impurities, we clean the impurities, rinse them with tap water, and then put the filter screen up.

If we have a filter at home, we should also remove and rinse it.

Dismantling and repair of local radiators.

If we find that a certain set of radiators in the home is not hot, then it is recommended that you find a professional plumber to check it. Because we need to dismantle the radiator, many friends will not operate it. In this case, the water supply and return water need to be turned off, then the water is discharged, and then the radiator is removed.

Then check for connection issues with the water supply return outlet. In fact, it is necessary to check the problem of the radiator itself. For example, we remove the return outlet, open the water supply, release the water to see if it is normal, and so on.

This eliminates any problems with the radiator and the connection.

Flush the radiator system as a whole.

In fact, whether it is floor heating or radiators, after a few years of use, there will be a certain amount of impurities accumulation inside due to the problem of impurities in the water. If there are too many impurities accumulated in these areas, it will affect the circulation of water supply and return water for our indoor heating. So at this time, you can find a professional radiator cleaning company or personnel to clean us.

When cleaning, high-pressure washing is generally used, and the impurities in the heating pipe and radiator can be brought out with high-pressure water, so that it can be cleaned. Especially for series connections, cleaning is very important.

1. Half of the radiator is not hot or the radiator has water sound or gas.

If the valve has been opened, and you touch the radiator with your hand and find that the radiator is hot in some places and not hot in some places, the possible reason is that there is still gas in the radiator, so that the heating does not have enough hot water, so the heating will not be hot at all.

Solution: Close the water inlet valve and leave a little water in, then close the return valve completely, open the air release valve for exhaust, when the gas is discharged, and finally when the water overflows, the gas has been discharged, and the exhaust valve can be closed.

2. All radiators are cold.

The radiators are cold, the heating is not hot at all, indicating that your problem is more serious, if there is no heating at home at all, it may be that the heating valve is turned off upstairs, and there will be no heating in your home, and the heating pipe design of your home is unreasonable, and the water inlet valve and return valve are not opened.

Solution: Find the reason and solve it, open the inlet and return valves, let the upstairs open the heating valve, and redesign the heating pipes, which can be solved, but the problems are really good.

3. Some radiators are not hot.

For example, the kitchen radiator is not hot? Bathroom radiators not hot? This situation is still possible, there are two common reasons, one is that the valve upstairs is not opened, resulting in the radiator in your home is not hot, and the other is that the kitchen or bathroom in your home is not hot, and the radiator is definitely not hot if the valve is not opened.

Solution: Let the property market open the valve, and there is no need to explain which valve in your home can not be opened.

4. The heating is not hot enough.

It means that there is still heating at home, but the heating is not hot enough, this is generally the initial stage of heating, like just starting to heat the water heating, at this time the radiator is not too hot, just a little residual temperature, this is a normal phenomenon, if it has begun to officially heat, or there is no good temperature, it is estimated that either there is a problem with the district heating, or there is a problem with the radiator in your home.

Solution: Let the property check whether the heating is normal, or check that there is a problem with the radiator in your own home, which should be compared with the heating situation of other owners' homes.

A group of radiators has a few hot and some are not hot, for the heating is hot below and the top is not hot, or there is the sound of water flowing in the radiator, etc. In the first half of the year when the heating begins, this situation often occurs due to the large amount of gas in the heating system of the entire community. There is a release valve on one side of the heating control valve, which is loosened counterclockwise to release the air in the heating, and it is necessary to deflate it many times, once or twice is not enough to put it clean, and it can be put once every other time until there are no bubbles in the water flowing out, and the heating can become hot.

If there is no gas inside the heating, check the status of the valve, whether all are opened, and according to the use time of the radiator, judge whether there is sediment blocking the pipe, causing the radiator not to be hot, you can find a professional installation master to dredge the pipe, in addition, friendly reminder, after the use of heating or floor heating for 2 years, clean the pipe once, so as to improve the service life of the heating and increase the use of heating.
