What are the reasons why the heating is not hot? The reason why the heating is not hot

There are many reasons why the heating is not hot, and today Jin Jin said several common reasons, floor heating and radiators should be said separately. Let's follow Jin Jin to find out.

Let's talk about radiators first, radiators are not hot, and a common reason is that the heating pipes at home are connected in series.

For series radiators, the water temperature of each group of radiators is different, which can generally ensure that the first three groups are hot, and then the temperature of the radiators will be lower and lower, and when the 4th or 5th is reached, the radiators are warm.

Once this is the case, there is no other way than to change the pipeline.

There is also a situation that the radiator is blocked, which may be the impurity of the water, or it may be the aging of the inside of the radiator, and the pipe diameter of the flowing water will be blocked.

In this case, the radiator should be cleaned, and if it is serious, the radiator should be replaced.

Radiators will talk about these two reasons, and then talk about floor heating.

There are two reasons why the floor heating is not hot, the first is that each floor heating pipe is too long, and the normal area controlled by each water separator is generally 13-15 square meters, and the length of the floor heating pipe will be about sixty or seventy meters.

Once the pipes of each road are too long, the resistance of the water in the floor heating pipe will become larger, the water flow will slow down, the water temperature at the end will be reduced, and the heating effect will definitely be greatly reduced.

The second reason is that the floor heating pipes are not cleaned in time, and some owners have not cleaned the floor heating pipes for seven or eight years since they got the keys to the new house.

This is a very wrong approach, and it can't just be used without maintenance.

If you don't clean the floor heating pipes for a long time, they will scale up and clog the floor heating pipes, just like blood clots.

If there is such a situation of the owner, you have to clean the floor heating too, in the process of cleaning. You'll understand why your home isn't heating up.

In addition to the reasons I just said, the heating is not hot, but also compared with last year, this is the problem of the heating company, we have a year before the heating of the whole area is not hot, and the previous year the heating was very good, this belongs to the external environment, we can not change.

Build-up, blockage, or improper installation. If the debugging fails to solve, then the radiator or pipeline may be blocked or seriously installed unreasonable, for the blockage or unreasonable installation, please disassemble and inspect the professional maintenance personnel to eliminate the blockage or reinstall the reasonable installation of the pipeline.

If the two qi is not hot, there are many reasons, one is that there is qi in the ancestor worship, which is blocked, and if it doesn't hurt, it will have to be a hair ring, that is, there is no cycle and no cycle to work together, and there may be no sleep.

There are many reasons, not enough pressure, there is air resistance, etc.!

5. In the early stage of heating operation or the unstable external network, most users compete to release water and gas, forming a vicious circle, and the amount of cold water is seriously replenished, or other users viciously release water, resulting in other users heating is not hot.

6. There is an air lock inside the radiator. There is hot water flowing in the heating pipe, and then a large amount of gas will enter, and there will be gas precipitation from the hot water continuously, and if it is not discharged in time, gas blockage will occur, and the hot water is difficult to circulate, resulting in the radiator not dissipating heat or dissipating heat slowly.

7. The operation of the heating system is out of balance, which can easily cause the radiator to not be hot, because the hot water flow in the pipe is unevenly distributed, and even some radiators only have a small amount of hot water flowing through. If the hot radiator is turned off, the non-hot radiator can be warmed up, which is a manifestation of system dysfunction.

1. The heating of a large area is not hot because the radiators on all floors or most floors of the whole community are not hot or the effect is not good, and the room temperature cannot meet the requirements, resulting in the heating is not hot, which is related to the design of dust heating, the insufficient output of the boiler, the insufficient water volume of the circulating water pump, and the operation of the boiler.

2 from the heater in the general area of the farthest user, the indoor heating is easy not hot, or the temperature is low, this is mainly due to the unreasonable design or not serious operation of the initial adjustment, indoor pipeline water imbalance, this is Xunxiang needs to improve the design or adjust the valve opening degree of each link.

3. The user has modified the heating equipment without permission, which may also be one of the reasons why the heating is not hot, and the new radiator that is too large or too small will affect the temperature of the heating, and the most affected are other users.

4. The local heating of the room is not hot, which may be due to the fact that the valve of the branch road is not opened or the opening degree is not enough, the gas collection on the main water supply pipe, etc., or the slope of the branch pipe of the individual radiator is not right or there is air in the radiator, resulting in the heating not being hot.

Introduction: There are many reasons why the heating is not hot, some are caused by improper use, and some are caused by climatic conditions, quality factors, etc. Let's take a look at the specific reasons why the heating is not hot.

(1) If it is the overall user, the heating is not hot, and the reasons are:

1. The heat exchanger and dirt remover of the heat exchange station are blocked due to scale, impurities and other reasons.

2. The valve of the heating pipeline is damaged and loses the adjustment function.

3. There is a leakage point in the heating pipeline.

4. Unforeseen reasons such as power outages and equipment damage.

(2) If it is an individual user, the reason for the heating is not hot is analyzed

1. The insulation effect of the house is not good, the top floor, the mountain, the first floor, and the old house are not insulated, and the isolated island (the surrounding neighbors are not heated and heated).

2. The indoor valve is not opened, and the heating pipeline in the house is aging, scaling, blocked, and the circulation is not good.

3. The indoor pipeline connection is unreasonable, and the pipe fittings are throttled (such as aluminum-plastic pipes connected to copper parts, copper elbows), etc.

4. The number of indoor heating equipment and the heat exchange area are not up to standard.

5. Air blockage. 6. The user discharges water for a long time without permission and adds a pump.

1. There are usually two kinds of heating: water heating and gas heating, the general radiator refers to water heating, which is to use the wall-hung boiler or boiler to heat the circulating water, and then link to the radiator through the pipe, and finally output the appropriate temperature through the radiator to form the indoor temperature difference, and finally carry out thermal circulation to make the entire indoor temperature rise uniformly.

2. Air heating is to heat the air, as soon as the cold air comes in, it is heated into hot air by the radiator, the hot air rises and forms a convection with the cold air of the house, and the cold air circulates to the vicinity of the heating to be heated into hot air, and the hot air circulates in the house, and the room is warm.

A good way to get warm is to install radiators. However, if there is a problem with the radiator, the heating will be blocked. Sometimes I will encounter the feeling of touching the radiator is very hot, but the room is not warm.

What's going on here? Let's follow Jin Jin to find out.

When it comes to winter, the northern cities are colder. Not only is the temperature cold outside, but also relatively cold inside. As a result, many homes will install radiators to keep warm.

Although radiators do not have the same wide range of heating as geothermal heat, they are still good for some small space houses. Especially for those families who have not installed underfloor heating before, the best way to heat is to install radiators. However, if there is a problem with the radiator, the heating will be blocked.

Although we felt hot when we touched the radiator, it was not warm inside. What's going on here?

The first point is that there is too much space and too few radiators.

Generally, when the radiator is relatively hot, it is not the radiator that is problematic. Generally, radiators are divided into sizes, and in larger indoor spaces, the size of the radiators is not enough, so you can choose multiple small radiators to disperse the heating. However, when we add, we must not add it at will, and we need to be tested before we can add it.

The second point is that the room is not well sealed when it is damp.

When we buy a house, we generally take into account the ventilation of the interior. Proper ventilation can effectively avoid too stuffy indoors, but it does not mean that the house is poorly sealed. Sometimes I feel that the airtightness is poor, because the location of the house is not good, and the lighting is relatively poor.

As a result, the house will be damp in the home, and relying on these radiators alone will not solve the problem.

Third, the location of the radiator is wrong.

When installing radiators, we can't just place them. The master said that the radiator should be installed on a wall with a window. This place is where cold air flows, and the convection of hot and cold can make it difficult for indoor air to rise.

However, it should not be placed at the door, as cold air can easily come in and is also a place where hot water flows can easily escape. The head of the bed in the bedroom should not be placed, because the rapid heating and alternating hot and cold air will affect the health of the family.

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 main reason why the heating is not hot is that the radiator or pipe accumulates gas, and the hot water in the system cannot circulate normally, and the heat cannot be dissipated, so the most fundamental way to solve the problem of not heating is to release the air in the heating system, and generally speaking, the amount of water released will be very small. Some users don't understand this, and blindly release water when the heating is not hot at home, which not only wastes Hongchi water resources, but also makes the hot water storage in the system insufficient, which aggravates the degree of heating is not hot.

The heating is not hot, does it really work to put water on the radiator?

If the user releases a large amount of water without authorization, the heating system is prone to hydraulic imbalance, resulting in insufficient water supply to the system. At the same time, the replenishment of a large amount of cool water, on the one hand, consumes energy, and on the other hand, it leads to the radiator becoming less and less hot.

The correct way to vent the heat when the heating is not hot.

There are many reasons why the heating is not hot, if the heating at home is not hot as a whole, it is likely that the outdoor inlet and return water valve is not opened, as long as the valve is unscrewed; If only part of the radiator is not hot, it may be due to the phenomenon of air locks inside, and it is necessary to unscrew the air release valve to deflect the air.

Under normal circumstances, under the premise of ensuring the pressure and temperature of the system, the heating is not hot, as long as the heating is deflated. The user gently loosens the manual air release valve by hand, and immediately stops twisting when he hears the exhaust sound, and if he sees a steady flow of water out, he can gently tighten the air release valve. After a period of time, repeat the above actions, and complete the entire exhaust process after two or three reciprocating.

During the entire exhaust process, there is no need to release a large amount of hot water.

Winter is coming, and heating is an indispensable heating equipment in my home. However, sometimes you may find that the heating is not hot, what is the reason for this? Let's take a look at it.

First of all, the heating is not hot may be because too much air has accumulated inside the radiator, resulting in poor water flow and affecting the heating effect. At this time, we can open the exhaust valve of the radiator and exhaust the air to restore the normal heating effect.

Secondly, the heating is not hot or it can also be due to insufficient water pressure in the heating system, resulting in a slow flow of water that does not achieve the desired heating effect. At this time, we need to check whether the water pressure of the heating system is normal, if the water pressure is too low, we can increase the water pressure by opening the water inlet valve to achieve the normal heating effect.

In addition, the heating is not hot and may also be due to the accumulation of too much dirt and debris inside the radiator, resulting in poor water flow and affecting the heating effect. At this time, we can remove dirt and debris by cleaning the inside of the radiator to restore the normal heating effect.

In short, the heating is not thermonuclear local due to a variety of reasons, and we need to investigate and deal with it according to the specific situation. If you can't handle it yourself, you can ask a professional heating maintenance personnel to check and maintain it to ensure the normal operation of the heating system. At the same time, it is also necessary to take care to keep the room ventilated and dry to avoid damage to the heating system caused by a humid environment.

Let's enjoy the warm heating on a cold winter day.
