Why is the house not hot when the radiator is particularly hot?

The radiators are particularly hot and the house is not hot for the following reasons:

1. The room is not well sealed when it is wet.

When buying a house, we consider the issue of ventilation, do not make the house too stuffy, and ventilate it reasonably, but this does not mean that the house is poorly sealed. The sealing of the house is poor, the location of the house is easy to get wet without seeing the sun, the moisture in the room will be aggravated, it is not enough to bake a few radiators, and the sealing of the doors and windows of your own home needs to be strengthened.

2. The position of the radiator is not installed correctly.

The location of the radiator is not decided randomly. Place a regular radiator on a wall with a window. It is a place prone to cold air, which is hot and cold convection, and the indoor temperature does not rise naturally.

But don't put it in front of your house, it's also a place where it's easy to get cold air, but it's easy to lose the hot air flow from the radiator. If it is a bedroom location, care must be taken not to place it at the head of the bed. The head is between the borders of the rapid alternation of hot and cold, and the family is prone to colds.

People with rhinitis are prone to sneezing.

3. Too much space, too few radiators.

If the radiator is very hot, generally the radiator is no problem, but the radiator also comes in different sizes. In places with a lot of space, the radiator is obviously not enough if the radiator is too small. You can choose a plurality of small radiators to disperse, or you can choose a radiator to install, but the radiators cannot be added at will, and they need to be tested and tested to change the problem of not heating in the room.

Precautions for the use of heating

1. Reserve the heat dissipation space of the radiator.

During use, try to leave some space around the radiator to allow the radiator to dissipate heat. It is best not to cover the radiator with a radiator cover or use it for other sundries, etc., which will affect the heat dissipation effect of the radiator.

2. The first heating must be exhausted.

For heating that is already in use, the owner cannot open the valve at will, as this will affect the water circulation in the system. And when the power heating is used for the first time, try to exhaust the pipes. When you exhaust at home, you can manually open each valve to remove the air in the radiator, and then turn off the valve after knowing that each radiator is hot, and use it normally.

1. The number of radiators is too small.

When it is determined that the valves are open, and the inlet water temperature is normal, then it is necessary to consider the relationship between the type and quantity of radiators installed in the house. Maybe the radiator is not hot just because the number of radiators in some residences is small, the house area is large, in the case of the heating system itself is not a problem, if the room is relatively large, it is necessary to increase the number of groups or pieces of heating in an appropriate amount, if the number of installations is too small, the heat emitted by the heating can not be transmitted to every place in the room, which is also one of the reasons for the radiator to be hot and the house to be cold. In short, the number of radiators should be proportional to the area of the house, and a large house area needs to add a few more radiators, so as to ensure the heating effect.

2. Whether the insulation effect of the house is up to standard.

Strictly speaking, whether the walls of the house are sufficiently insulated is a big factor, in most cases, the walls of the houses in the north are better insulated, while the houses in the south do not consider the heating factor, and the insulation of the walls will be weaker. On the other hand, the sealing of the room, if the airtightness of the room is poor, it is difficult for the residents to rely on a few pieces of heating to resist the influence of the outdoor environment, resulting in most of the heat emitted by the room leaked to the outside, and the loss is lost in vain, so the radiator is very hot, but the room is not warm. In this case, consider insulating the exterior walls, or adding sealing strips to the doors and windows, which will reduce the entry of some cold air.

3. Whether the installation position of the radiator is suitable.

The installation of radiators is not simply to hang the radiators on the wall, the installation of radiators needs to conform to its working principle, the regular radiator factory will arrange professional HVAC engineers to carry out door-to-door measurement and design of the installation environment, and then according to the principle of thermodynamics to determine the final position. If the radiator is installed in the inside of the room, the cold air from the outside of the window will continue to come in, and there is no way to heat the cold air from the inside of the window. Due to the poor air flow in the room, the convection heat dissipation amplitude is small, and the heating speed of the room is relatively slow, and the room temperature does not rise for a long time, or the heat and cold are uneven.

In addition, many users add a cover or a full package to the radiator for the sake of aesthetics during installation, which affects the heat transmission.

The radiator is hot, there are many possibilities for the room not to be hot, first of all, the installation and connection of the radiator is one of the reasons, the main manifestation of this reason is that the radiator temperature is high, and the lower position is not hot under one-third, because the radiator is not connected in the right way, it should be connected to the diagonal position, so that the low in and high out, because the heat is going up, and the air conditioner is down.

There are also some friends whose homes are old houses, and there is no insulation layer on the exterior wall, so that the radiator will heat slowly, and some new communities have insulation on the exterior wall, but the floor is the top floor or side household, and such a house is also slow to heat.

In fact, the radiator is installed at the door and installed under the window, the effect of thermal insulation is very different, it is best to install it under the window, it is best not to install it at the door, after all, it affects the warmth of the room back and forth.

These three points are relatively easy to ignore the problem, so when you touch the radiator and feel that the room is not hot, you can sit down and see if there is a problem, these "three" big problems are not solved, no wonder they are frozen into dogs.

The best place to install the radiator under the window is the best place to match the convection and raise the indoor temperature.

1. The water temperature of the heating water supply is not enough.

When the water supply temperature needs to be 80 degrees, the temperature in the room can reach 20 degrees, and if the water supply temperature is only 50 degrees, the room temperature is only about 10 degrees.

2. If the water supply valve is partially closed, resulting in a decrease in water flow, the temperature of the room is not high.

For example, your room needs a water flow of 3 square meters per hour, and the room can be hot, but the valve is closed a little, resulting in a decrease in water flow, and only 1 square of hot water flows through every hour, and the temperature lost in the room is reduced a lot, and the temperature in the room must not go up.

2. If the number of radiators does not match the area of the room, the temperature of the room is not high.

For example, if a certain type of radiator has a single heating area of 2 square meters, and you have 20 square meters indoors, you need 10 heaters to form a group of heating. But if you only use 8 tablets, the temperature in the room will not be high.

The radiator is hot when heating. But it's not warm inside. On the one hand, it's because your room has a lot of space and fewer radiators.

The house is high. On the other hand, it is. If the insulation is not good, is there no insulation layer on the exterior wall?

The room is not tight and has a ventilated place. You can add a few more sets of radiators. Do the insulation well, a little.

That's it.

Hello, it is not recommended to measure the temperature of the radiator, as long as the indoor temperature is comfortably kept at about 20 degrees.

Why do radiators burn but don't dissipate heat?

Some of the heating rooms are hot and some are not hot, it may be that the radiator is blocked by scale, and the air inside the radiator is too much, which is described as follows

The radiator scale is blocked, the heating is hot in one house and the other house is not hot, it is definitely not the problem of hot water not hot, it should be the scale blockage of the radiator or pipe in the room that is not hot, resulting in the hot water can not be circulated normally, and the scale heat conduction efficiency is very poor, and the thick scale will affect the heat transfer.

Clean the radiator in a room where the heating is not hot, or you can clean the heating duct in the room by closing the other valves on the water separator and then cleaning the pipes in the room. To remove limescale from pipes and radiators, it is best to have a professional cleaner do so.

There is too much air inside the radiator, and the air blockage inside the pipe and the radiator is also the main reason for the heating not to be hot, when there is a lot of air inside the pipe, the air blockage will be formed inside to make the water circulation in the radiator not smooth, and many users will have this situation after using it for a period of time.

Drain the air inside the radiator and release the excess gas from the exhaust valve, and when you see that there are no bubbles in the discharged water, it means that the gas has been drained. It is recommended to ask a heating maintenance personnel to exhaust the gas, if you want to exhaust yourself, you can read this article "How to drain water when the heating is not hot".

Recently, we have been receiving inquiries from users on a regular basis**. In such a situation, what should the user do can solve the problem in the shortest possible time. Today, I will give you a detailed answer.

Reasons why radiators are not hot

See if it's a problem with the boiler. In order to save fuel costs, some communities use inferior fuel for heating, resulting in substandard heating; It is also possible that the boiler water channel is seriously scaled, resulting in low boiler work efficiency.

Check to see if the circulating pump has a low pressure point. In order to save electricity, some heating management units will stop the circulating pump, resulting in the instability of the system and ultimately affecting the heating effect.

The make-up pump is low for the negative pressure point. If the radiator of a tall building is not hot, the user can check whether the make-up pump has a low pressure point, whether the make-up pump inverter is faulty, and the make-up tank is not timely, etc.

Whether the heat exchanger in the heat station is damaged. When the heat station carries out the secondary heat exchange, whether the heat exchange of the existing heat exchanger cannot meet the actual needs of the user due to the small selection of the heat exchanger, etc.

Supervision and management. Some heating operation units lack management mechanism, employees lack a sense of responsibility, and the outdoor temperature and weather continue to change during the heating period, but the heating management unit is not timely in regulation and control, resulting in heating errors.

The radiator does not heat the performance

The radiators of the whole complex are not hot enough.

None of the radiators in a user's home are hot.

Only a few of the radiators in a group provide good heating.

A set of radiators, not hot above, hot below.

The radiator is not hot solution

The radiators of the users in the community are not hot enough, and the general reason is that the heating temperature is not enough. If the radiators in the neighborhood are not hot, you can directly find a heating unit, and if the indoor temperature is not up to standard, the heating fee can be refunded.

If all the radiators in your home are not hot, then you need to check the reason, whether the home heater was hot last year, so as to determine whether there is a problem with the installed pipes, if it was hot last year, it is not hot this year, you can check whether the valve and temperature control valve of the radiator are open. If it still doesn't work, it should be that the radiator is blocked, and you can find a professional cleaning person to clean it.

If the radiator has several groups of hot and several groups are not hot, or check whether the radiator valve is open, this reason is generally that the radiator is collected in the gas, which is caused by the phenomenon of "gas blockage", and it is recommended to deflate the radiator.

The radiator is hot above, not hot below or not hot at the top, hot below, this should be a bad heating cycle, you can find a professional to test the water inlet pressure and return water pressure, to see if the pressure difference is too much, whether the heating in and out of the water pipe is reversed. If this is the case, the pipes need to be modified.

Through the above methods and summaries, it is found that the situation in your home is the third item in the solution to the radiator not hot.

What's going on with the radiator and whether it's hot or not: under normal circumstances, the group that is not hot is holding air, and each group of radiators has an exhaust valve, the purpose is to help you encounter this kind of thing after you can move the exhaust valve, and the exhaust problem can be solved, if it can't be solved, you have to see if the inlet and return valve is not open, if everything is normal, there is no problem.

There are hot and non-hot in the same group of heaters, it is likely that there is gas in it, and the water cannot pass through, and the water can be discharged and exhausted through the exhaust hole. It may also be that there is a foreign substance in that piece that cannot circulate normally, which requires cleaning the internal structure. Generally, there will be no other problems.

Try to put some water in the one that is not hot, it may be that there is air in it, and the water can fill the whole radiator after it is released.

You need to twist the screws on the side to deflate, there is a possibility of squirting water, it is best to let the property get it, to prevent it from getting water everywhere.

It is possible that limescale deposits are causing local blockages.

Many homes use radiators to provide a comfortable environment for their families. But the radiator has been used for a long time, and it is inevitable that there will be some situations, such as some rooms are hot, and some rooms are not hot, which makes people feel very uncomfortable. So what causes this?

Let's take a closer look.

1. Whether the valve is open.

If the temperature control valve is not fully opened, it will cause some rooms to be hot and some rooms to not be hot, so we should check whether the valves are all open.

Second, the radiator gas blockage phenomenon.

If air enters the radiator's duct system, it will block the flow of hot water in the system's ducts, resulting in uneven heating and cooling of the radiator, or even the whole room is not hot. In this case, simply deflate the radiator to make the hot water flow smoothly in the pipes. First close the pipeline valve, slowly unscrew the air release valve, pay attention to the action slowly, when you hear the sound of gas discharge and water flow, stop twisting the air release valve.

Then repeat this step slowly, and wait for the gas to be exhausted automatically to ensure a stable heating supply.

In the process of daily use, the user should deflate the radiator regularly, and do not wait until the temperature of the radiator is unstable to deal with it.

Third, there is a water leakage problem.

Since normal heating systems should be in a closed-loop system. If there is a leak in the pipes, heat will inevitably be lost, causing the temperature of the heating radiator to drop. Once a leak is found, it is necessary to immediately ask a professional maintenance personnel to repair it. It's a ride.

Fourth, the input temperature of the low heat source.

In some central heating areas, in the early stage of heating, the system is in the testing stage, and the temperature itself is not high, and the heating radiator will not be very hot when transmitted to the beautiful home. It is necessary to wait patiently for the heating system to be commissioned before the temperature rises. If you encounter this problem, you can consult your neighbor if there is such a situation, and then consult the heating company how to deal with it.

Fifth, the quality of the radiator itself.

The quality and coarse quantity of different radiator products are different. The radiators of the brand radiators have a high thermal efficiency and can quickly reach the desired temperature when opened. Some radiators need to be heated for a long time because of their large water capacity.

There are also radiators that are of poor quality and the temperature rises relatively slowly.
