The radiator in the master bedroom only heats the top half, what should I do?

During the New Year's Day, I happened to find that the radiator at home also had this problem of the first half being hot and the lower half being cold. The cause of the problem: The heating water pressure set in the wall-hung boiler is not enough, and it is said that it should be set to the left and right.

But my house is on the top floor, and the water pressure is up, and when it doesn't arrive, it can't be added anymore. Tears smiled and said that many users on the top floor of Xindi generally have insufficient water pressure. Workaround:

I increased the heating water pressure to the maximum, about what it looks like. Turn off the radiators in the bathroom and kitchen a little bit or turn them off completely, wait a while, and then touch the radiators in other rooms and living rooms, and you'll notice that the lower half is starting to heat up as well. After normal, open the heating valves in the bathroom and kitchen a little wider.

According to my observation, the temperature of the lower part of the radiator is usually slightly cooler than the upper part, and the radiator in the direction of the water outlet is also a little cooler than the direction of the water inlet. I think that's normal.

Unscrew the exhaust valve, is your water jetted? In the beginning, it was the same in my house, and the heater asked me to keep it on, put more water, and put the water in the form of a drip ......Why don't you try it too, but the heating in my house hasn't been changed.

Reply 3 There is no need to turn off the heater of the wall-hung boiler, close one of the two valves for the inlet and return water, and then start to drain the water.

My house was the same at first, but when I finished venting, it didn't show up, and it was hot up and down.

What heating did you change? Just ask them to take a look at it for you.

Reason 1: Too much gas.

It may be that there is too much gas in the radiator, and the pipe is blocked, which will cause the problem of local heat. Especially when the heating is just now, there will be a lot of air stored in the radiators and pipes in the heating system, if the air is not cleaned before use, it will cause the water circulation to not be particularly smooth, and then there will be half hot and half not hot.

Solution: If there is gas inside that blocks the pipe, in this case, we need to open the exhaust valve on the radiator to drain the air inside, so that the heating system can circulate smoothly. When draining, you should wait until the water inside comes out before closing the exhaust valve, after which you will find that the part of the radiator that is not hot will gradually heat up.

After installing the radiator, it is also necessary to install the exhaust valve, and the exhaust valve is manual and automatic, which can be selected according to the needs. When an exhaust valve is installed, the service life of the radiator can also be effectively extended.

Reason 2 for the radiator to be half hot and half not hot: improper installation.

It may be that the installation is not in place, for example, the pipe connection is wrong, or the inlet pipe and the return pipe are reversed, at this time, the heating system will not be able to operate normally, and there will be a local problem of not heating.

Solution: If there is a problem with the installation, it is especially important to pay attention to the need to ask professional staff to check and repair it, and to reconnect the wrong pipe.

Causes and solutions for radiators that are half hot and half not hot.

Reason 3 for the radiator to be half hot and half not hot: clogged pipes.

If the pipes of the heating system are blocked, the radiators will also be not hot or partially not hot.

Solution: When this kind of fault occurs, you should ask a professional maintenance personnel to check it, judge the blockage point, and then disconnect the pipe, remove the contaminants or reinstall the unreasonable pipeline.

Reason 4 for radiators that are half hot and half not hot: hydraulic imbalance.

Some radiators are not hot, but the hot ones are turned off and the ones that are not hot can be heated up, a phenomenon called hydraulic imbalance of the indoor circulation system.

Solution: To deal with this situation, you can adjust the indoor system, turn off the hot heating first, let the non-hot heating heat up, and then slowly turn on the hot heating.

The following are the reasons why the heater is hot above and not hot below: 1. There is too much gas in the radiator: blocking the pipeline will produce a situation where the radiator is not hot locally.

2. Pipe access error: the water supply and return pipes of the heating system are just reversed to the water supply and return pipes of the whole building, or all are connected to the water supply (or return) pipes, so that the normal thermal circulation line cannot be formed, resulting in the lower half of the radiator not being hot. 3. Heating system pipe blockage:

If the pipes of the heating system are blocked, the radiators will naturally not be hot or partially not hot. 4. Unreasonable installation of heating system pipeline: unreasonable installation will cause air plug inside the pipeline, block or reduce the flow cross-sectional area of the pipe section, thereby causing local heat.

5. There is sediment in the radiator: when the radiator is hot on the top and cool on the radiator, it indicates that there is sediment in the radiator. It is necessary to open the loose joint cleaning block.

6. Heating adjustment is not in place: In a single-family family, if the lower half of the radiator is not hot, the reason is likely to be that the heating adjustment is not in place.

Under normal circumstances, the temperature of the upper half of the radiator should be higher than the temperature of the lower half. At present, most of the heating is plumbing, hot water generally enters from the upper water inlet, flows out from the lower drain, the radiator dissipates heat to the indoor space through the surface of the radiator, the temperature of the water will drop, and it will be discharged to the pipe and flow back to the boiler for reheating, forming a cycle. Of course, the inlet water is higher than the return water temperature, and according to the "convection principle", the hot water rises and the cold water falls.

The radiator has only one piece of hot reason:

1. It may be because the direction of the water flow for the return water is connected incorrectly, and the return water of the first radiator is directly connected to the main return pipe, then the water flow direction for the return water should be reconnected according to the correct method.

2. It is also possible that there are too many turns in the water supply pipeline line, and there is gas accumulation at the bend, which causes the water supply and return to be unable to circulate normally and deteriorate.

3. It is also possible that there is air in the heating system behind it, which causes the radiator to circulate poorly, so the radiator should be deflated.

4. It may also be because when the radiator is installed, a lot of impurities are accidentally left in the radiator, resulting in the radiator system being blocked and the circulation is not smooth, so the radiator should be cleaned and dredged.

Precautions for purchasing radiators:

1. Look at the size.

There are a variety of specifications and models of radiators on the market, different specifications and models, their size, **, suitable installation location will be different, when we buy radiators, we must choose according to the actual area size of the radiator installed at home and their own needs and economic capacity.

2. Look at the brand.

There are many brands of radiators on the market, different brands, their first, production technology, production equipment, shelf life, product quality, after-sales service and other aspects will be different, we are in the purchase, it is best to choose products produced by big brands and good reputation brands, so that product quality and after-sales service will be more guaranteed.

1. Causes and solutions for some hot and some not hot:

Reason: The existing heat of the radiator and the phenomenon that some are not hot may be because the water separator valve of the radiator is not opened;

Solution: The valve handle can be screwed parallel to the branch pipe;

Second, half of the radiator is not hot causes and solutions:

Reason: Air in the radiator: At the beginning of heating, residual air is accumulated in the pipes and radiators of the heating system, which will cause poor circulation of hot water, and then make the radiator not hot.

Solution: At this time, the air conditioner should be opened, and the air in the radiator should be exhausted before shutting it off.

3. Reasons and solutions for heating that is hot at the bottom and not hot at the top:

1. Reason: The device of the radiator is down, that is, the radiator is installed on the top with a water retainer, and the bottom has become straight, and the hot water has all gone away from the top. It is also formed because of the water retaining sheet.

2. Reason: There is no water stopper, the water pressure is too large, the cold water and hot water barrier are broken, and the cold water below cannot flow back. Such cases are rare.

Solution: Just close the small point of the water inlet valve, and there should be no results without adding a water shield on it, but the heat dissipation should be less than the original.

The phenomenon that the radiator is hot and some are not hot may be because the water separator valve of the radiator is not opened.

The part of the radiator is not hot and there is a sound of running water in use, the reason for this failure is the accumulation of gas in the radiator, and the air valve needs to be opened to release until there is water flowing out.

The heating is hot at both ends, but not in the middle, and the solution is as follows:

The phenomenon that the radiator is hot and some are not hot may be because the water separator valve of the radiator is not opened. Solution: The valve handle can be screwed parallel to the branch pipe;

The part of the radiator is not hot and there is a sound of running water in use, the reason for this failure is the accumulation of gas in the radiator, and the air valve needs to be opened to release until there is water flowing out. At the other end of the control valve, there is a vent valve that can be adjusted with a screwdriver, and the valve is loosened counterclockwise to release the air in the heater, and the heat can become hot. Note that it is necessary to deflate several times, once or twice is not enough to deflect cleanly, and it is enough to deflair once every other until it is exhausted.

The heating vent valve in the bathroom is at the top of the heating. If the fault cannot be eliminated after operation, notify the maintenance personnel.

I've tried asking questions, but I can't do it!

Let them check it out.

They're a little bit more professional.

There are many reasons why the radiator is not hot, such as your installation location, the size of the radiator, the water problem of the boiler, whether the radiator pipeline is blocked, the water pressure problem, whether the pipeline is relatively small, resulting in a small water flow, etc.

The radiator is only half hot, it is likely that there is an air blockage, you can be trapped vertically through the air release valve, generally Xiaohong can be solved, of course, there are times when you need to be careful to deflate many times, Rubens heating hopes to help you.

I believe that many people occasionally encounter the situation that the radiator is half hot and half not hot after the heating is turned on. So what is the reason for this? How to solve it? Can it be warmed up by deflating? Let's follow the golden flagship flag brother to find out.

1. The heating angle valve is not opened

There will be inlet valves and return valves up and down or left and right of the radiator, and if the inlet valve or return valve of the radiator is not opened, this situation may also occur that a certain group of radiators is not hot.

Solution: The solution is also very simple, you need to open the radiator inlet valve and return valve.

2. Radiator blockage

This kind of radiator blockage phenomenon is also very common, sometimes there is too much sediment in the radiator, too much water alkali, too much rust, etc., which will cause the radiator to be blocked.

Solution: When this kind of fault occurs, you should ask a professional HVAC company maintenance personnel to conduct a door-to-door inspection, judge the blockage point, and then disconnect the pipeline, remove the pollutants cleanly, add a trap for return water filtration, and then you need to clean the water valve filter regularly.

3. There is too much gas in the radiator

At the beginning of heating, a large amount of residual air is accumulated in the pipes and radiators of the heating system, resulting in poor circulation of hot water, and then the radiator is not hot, and the radiator is locally hot.

Solution: Just open the air release valve on the side of the radiator, drain the air, and wait until the hot water comes out. Then close the release valve, so that the radiator will gradually heat up as a whole.

4. The pressure of the heating system is insufficient

With the continuous improvement of people's requirements for the living environment, the heating area of the district is increasing year by year, and the heating pressure of the heating station is also increasing year by year, which leads to the mismatch between the heat supply and the heating area of the original design of the community. It is mainly reflected in the fact that the building heat close to the heat source is not hot, and the far one is not hot, or one part of the room in a building is hot, and the other part is not hot, or the upstairs is hot, and the downstairs is not hot, which is caused by insufficient heating pressure.

Solution: When encountering this kind of professional problem, for owners who do not have HVAC professional knowledge, they should ask a professional HVAC installation company to inspect and overhaul them, and do not disassemble or repair them by themselves.

Kiss! Hello, happy to answer your <>

First, if the upper part of your radiator is hot and the lower part is not hot, it may be because there is too much air left in your radiator. Because once too much air accumulates in the radiator, it will cause the airflow to be unobstructed, which will make it difficult for the heat to spread when it is found. Over time, the so-called upper part of the radiator is hot, and the lower part is not hot.

In view of this situation, we need to deflate the radiator some time, so we need to open the radiator's venting valve first to deflate. When the water flows out of the radiator slowly, it means that the deflation work has been completed, and we can close the deflation valve. Second, the upper part of the radiator is hot and the lower part is not hot, which may also be caused by the wrong installation of some pipes during the original installation.

It is possible that we have installed the return pipe and water inlet pipe of the radiator wheel, and the main return pipe and the main water inlet pipe connected to the heating system in the community, so that your radiator does not have a normal heating system, and it cannot form a normal heating environment. When we encounter this situation, we need to find a professional to inspect it first, and then install the wrong pipe correctly. Hope mine can help you <>
