What is the reason why the heating in the home is not warm in winter?

For heat dissipation facilities in the home, radiators are more commonly used. However, for radiators, you will find such a phenomenon, that is, the radiators that were very hot last year, but after a year, they are not hot again, and the probability of this phenomenon is very high. So why does the radiator appear not hot?

And how to solve it? The following household miscellaneous altar will formulate different treatment methods for different reasons why the radiator is not hot.

In the cold winter, heating is an indispensable heating system for us. When in use, users often encounter the problem of heating not being hot, which is a headache. So what if the heating isn't hot? What is the reason why the heating is not hot?

<> the reason for the heating system.

To check if the heating system is blocked, touch the heating pipe with your hand first, if the pipe is not hot, the heating system may be blocked. The blockage may be due to the fact that the heating pipe has not been maintained and maintained for many years, and a large amount of scale and sediment accumulation leads to fouling of the inner wall, increased thermal resistance, and poor water flow; Central heating areas can be caused by accidentally closing the main line valve.

There is an air blockage in the heating pipes.

Check if the flow rate of the system is too low or the air content of the circulating water in the system is too high. If you touch the heater with your hands, it is cold, it may be that the heating drain valve is out of order, resulting in a large amount of air accumulating in the heater, so that the heater is not hot; The heating has the sound of water, or it may be that there is gas inside the radiator that cannot be discharged.

Human causes. The heating is not hot due to human reasons, such as the user's disorderly deflation, water discharge, unauthorized heating change, failure to pay the heating fee, etc., may affect the heating of their own home. The heating effect of the heating is related to the product itself, installation and after-sales service, and the user's usual use habits.

How to prevent air blockage.

If the user has not used the radiator for a long time, there may be air blockage a few days before heating. Jin Jin recommends that you unscrew the needle bleed valve at the end of the radiator a little, but do not unscrew it, and close the bleed valve when you hear a bang. This allows it to be repeated every day for 3-5 days after the start of heating.

Regularly deflate the radiator to avoid the radiator from being treated when it is not hot, ensuring the stability of heating and improving the user's comfort.

If the heating at home is not warm, it may be that the water boiled by the heating company is not hot, or the heating pipe at home is blocked, leaking and other problems, resulting in poor circulation of heating.

The first possibility is that there is a problem with the heating pipe, which may be that the heating pipe is broken, resulting in the heating not being connected. The second possibility is that the room is leaking, so no amount of heating can warm the room. There is also a problem with the heating system.

First of all, determine whether to turn on the heating switch, if it is turned on, it is very likely that the heating pipe has broken in an accident, resulting in the heating can not reach the house, in this case, only ask a professional to repair.

The main reasons for the lack of heating in the user's home are as follows:

First, due to the implementation of the sequential furnace staggered peak opening work, the hot state trial operation of some heating source plants is not sufficient, and the time for individual district heating systems to enter stable operation conditions is slow;

Second, the temperature in the early stage of heating is low, the ideological preparation of individual heating units is not sufficient, and there are problems in the regulation of the heating network, resulting in many failures in the operation of the pipe network;

Third, in accordance with the "blue sky project" deployment, some of the new network district heating operation parameters need to be matched and adjusted, especially the heating area of Shenyang Huanggu District Heating Company connected to Shenyang Guoxin environmental protection new energy ****, due to the large amount of construction of the pipeline network in the early stage, the trial operation work is not sufficient, and the secondary network runs and drips to affect the balance of the heat network;

Fourth, it is due to the phenomenon of wind holding and blockage in the user's indoor pipeline in the early stage of heating, which affects the heating effect;

Fifth, it is the legacy problems of individual new real estate developers that cause untimely heating;

Sixth, it is external factors such as power outages and water outages that affect the initial water supply and boiler temperature improvement of the pipeline network.

1. Close the water inlet valve and the return valve, close the valves of the geothermal pipe, and close the air release valve.

2. Open the water inlet valve of the main pipeline, open the water inlet and air release valve of the distributor, and release the water into the main pipeline.

3. Close the inlet air release valve, close the water inlet valve of the main pipeline, open the return water release valve of the distributor, open the return water valve of the main pipe, and release the heat of the return water main pipe.

4. Close all valves, open the water inlet and water return of the main pipe, open the return water release valve, open the water inlet valve of the first geothermal pipe of the distributor, and close it after the water is hot.

5. After all the heat is released, open the water inlet and return valves of the distributor and close the two air release valves.

The main reasons are as follows:1Gas. The indoor heating part is not hot because the radiator has gas in the area, which causes the phenomenon of "gas blockage", and it is recommended to vent the radiator.

2.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.

To deal with this situation, the room system can be adjusted to turn off the hot heater first, let the non-hot heater heat up, and then slowly turn on the hot heater.

3.Blockage or unreasonable installation, private modification: If the above methods can not be solved, then the radiator or pipeline may be blocked or seriously installed unreasonable, at this time, it is necessary to ask professional maintenance personnel to disassemble and inspect to eliminate the blockage or reinstall the reasonable installation of the pipeline to eliminate.

1. The reason why the heating is not hot.

1. The make-up pump is low in negative pressure points. If the radiator is not hot, the user can check whether the water pump is low and the inverter of the water pump is not hot.

, maybe the refill tank is small, etc.

2. Check whether the circulating pump has a low pressure point. Some heating management units save electricity, which will stop the circulating pump, resulting in no fluctuations in parts, and ultimately affecting the heating effect.

3. Monitoring and management. The local heating operation unit lacks a management mechanism, the employees lack a sense of responsibility, and the outdoor air level and climate change from time to time during the heating period, but the heating management is single.

The control of the position is not appropriate, resulting in heating errors, etc.

4. Whether the heat exchanger in the heat station is damaged. When the heat station stops the secondary heat exchange, can the heat exchange of the existing heat exchanger not meet the user's reality due to the small selection of the heat exchanger?

Practice needs and so on.

5. Check whether it is a problem with the boiler. Some communities save fuel costs and use inferior fuel for heating, resulting in substandard heating; There are also those who can be boilers with severe fouling on dry roads.

The task of reforming the boiler is inefficient.

You can find a heating company and they will solve it for you. The heating in many homes is not hot, and I don't know how.

Summary. 1.First, find out why the heating is not hot.

2.Determine whether the inlet and outlet water temperature of the entire heating system in the area is up to standard, if not, by the heating department and the property association. 3.

The heating at home is not hot, it may be that the gas in the large system is not clean. Report to the property or thermal supervisor and let him operate. 4.

If not, the problem may lie in the inappropriate design of your own pipelines. If you want to solve it, please have it on the time.

It is also possible that the neighbor's renovation is unreasonable, which destroys the hydraulic balance of the overall heating system. After discovering the problem, it is best to report it to the property, and they will come forward and urge the neighbor to rectify the unreasonable part.

The reason for the heating itself is that the heating at home is not hot, or it may be because of its own reasons, because it is too old, or when you are at home, you feel that the installation of a cover is more beautiful, although beautiful, but flashy, it is simply redundant! That's why the heating at home won't be.

1. The heating is not hot due to a wide range of heat outages.

First of all, ask the unit or community heating station whether there is a power or water outage, whether the heat source or heat station equipment is faulty, and whether the heating main network is faulty, resulting in a large range of residential buildings and office buildings to stop heating at the same time, and then repair and solve it according to the corresponding situation.

2. The radiator is not hot due to air blockage or foreign body blockage, valve core falling off, etc.

In general, in this case, part of the radiator is hot and part of the radiator is not hot. Open the manual bleed valve at the rear of the radiator to vent the air; Open the exhaust valve located at the highest point (top level) of the system to exhaust the air; Open the water supply and return valves in the upstairs and downstairs users' homes; Foreign body blockages should be dealt with by property or professional maintenance personnel.

3. Installing or altering the radiator without permission causes the heating to be not hot.

The installation of radiators has strict technical requirements and must be installed under the window, so that the rising hot air flow can block and directly heat the cold air flow that penetrates through the window crack, so that the air flowing through the room is warmer and more comfortable. Users install and modify radiators without permission, because the installation is not standardized, the position is unreasonable, and there are many turns, resulting in heating blockage and excessive water resistance, which not only does not heat their own heating, but also affects all the heating connected by the same pipe up and down the whole building. It is advisable to have a professional install the radiator.

4. The hot water in the radiator is not hot.

The hot water in the pipe network contains chemicals for the maintenance of the heating pipe (corrosive to the human body), and bathing and washing clothes with the hot water in the heat pipe network not only affects the pressure of the heating network, but also affects the health of people. In order to ensure the pressure of the heating network and the health of the individual, please do not modify the heating package vent valve into a faucet to privately release the hot water in the radiator, which will destroy the balance of the entire heating pipe network.

5. The design of the pipe network is unreasonable, and the debugging is not in place, resulting in the heating not being hot.

Due to the unreasonable design, the installation of flow balance adjustment equipment or the adjustment of management personnel is not in place, the heating flow is unbalanced, and the temperature difference between buildings is large, and some heating is not hot. Please ask the property or unit in the community to debug the pipe network or rectify the courtyard pipe network.

6. The heating is not hot due to poor sealing of the room.

The doors and windows of some users' houses are not tightly sealed, resulting in poor insulation effect of the room, and the radiator is hot and the room temperature is not high. Users are advised to take appropriate measures to enhance the airtightness of the room.

7. The number of radiators installed is not enough, resulting in the heating not being hot.

In order to save costs, some builders do not install radiators in small living rooms and toilets, resulting in users not heating their homes. It is recommended that users choose the right radiator brand in tens of millions of shopping malls, contact professional personnel for door-to-door measurement, recalculate the required quantity and arrange the installation of radiators.

The first reason is that there is air inside the radiator. This will cause air blockage and poor water flow inside the radiator.

The second reason. The radiator line is blocked. When the radiator close to the boiler heats up quickly, the radiator that is far away heats up very slowly, which is mainly due to the short circuit formed inside the radiator, resulting in the hot water only forming a small circulation in the area close to the distance.

The third reason. The radiator valve is broken. Due to its frequent use, its internal parts are prone to damage.

The fourth reason is that the radiator is clogged, which causes the radiator to not heat up. Due to water quality reasons, many radiators are easy to be adhered to scale after long-term operation and inside, and they are prone to pipe blockage after long-term accumulation.

Generally, the heating is not hot The situations are: insufficient pressure, slow circulation needs to be repaired, there is air blockage in the heating, gas needs to be deflated, the heating filter is blocked, the heating pipe is blocked, the radiator is blocked, part of the radiator is not hot, the hot one is turned off, and the non-hot one can be heated up, this phenomenon is called the hydraulic imbalance of the indoor circulation system.

In winter, the radiator at home is not hot, and the air generated in the pipe or radiator is generally caused by the radiator not being hot, so it is recommended to discharge the air in the pipe and radiator.

The heating company has insufficient heat supply, the pipeline is too long, the insulation is poor, the radiator installation position is insufficient, the number is insufficient, it is blocked, there is gas, and the room insulation effect is poor.

1. The heat source itself is not hot, 2. The pipeline is blocked, 3. There is air that is not discharged.

First of all, consider whether the heating water temperature is up to standard, secondly, consider whether there is air resistance, and thirdly, consider whether the heating pipe is smooth.

Maybe there's a problem with the heating, or the house doesn't have insulation.

If the heating is not hot, then complain.

Then put the water out.

If you have been using it all the time, every year, it is time to deflate. This way the water can circulate and become hot.

Municipal heating is also self-installed heating equipment.

Radiator exhaust, pipe circulation inspection, filter cleaning.

01 The radiator contains air and causes air blockage.

Fault performance: half of the radiator is hot, half is not hot, this is a more common problem in the early stage of heating, there is residual air in the radiator pipe, blocking the pipe, affecting the water circulation of the pipeline, resulting in uneven heat dissipation.

Solution: Open the exhaust port of the radiator for exhaust, and drain it several times to ensure that the air in the pipe is emptied.

02 The temperature control valve is not fully opened.

Fault performance: The radiator in some rooms is hot, while the radiator in some rooms is not hot.

Solution: Check the thermostats to make sure each one is open.

03The radiator is clogged.

Fault performance: the heating effect of the radiator is getting worse year by year, and some radiators are not even hot, and the general fault is eliminated, it is very likely that the radiator or heating pipe is blocked.

Solution: The radiator can be cleaned.

04 The installation position of the radiator is unreasonable.

Fault performance: all the radiators in the home are heated normally, but the room temperature always does not meet the requirements. It may be caused by the improper installation position of the radiator.

Solution: Reinstall the radiator.

Radiator Installation Rules:

The best place to install is at the bottom of a window or on a cold wall (see picture below). Although this will increase the heat loss in the room, it will make the heat more evenly distributed in the room and more comfortable (see the figure below right for the effect of the radiator installation location on the indoor temperature distribution).

05 radiator quality problems.

Fault performance: everything else in the home is normal, and the radiator installation position is reasonable, but the radiator is not hot. That may not be good for the heat dissipation of the radiator itself.

Solution: The radiator with better heat dissipation effect can be replaced, and the Rolet radiator adopts a cold-rolled steel plate design, which can quickly heat up, realize indoor convection, and save energy.
