Can you put water when the heating is not hot? How to put water when the heating is not hot

Is it useful to put water when the heating is not hot.

Not necessarily useful. There are many reasons for the heating is not hot, such as the hot water itself is not hot, the scale is blocked or the indoor insulation effect is poor, etc., in these cases, the water can not be solved, only when the radiator is not hot due to air blockage, the water discharge has an effect.

How to maintain radiators.

1. Check whether there is water leakage.

When heating, the external temperature is relatively high, and the temperature of the heating facilities will be reduced when not in use, and then there will be the phenomenon of thermal expansion and cold contraction, especially at the pipe interface, for example, if the interface is loose, there may be water leakage. After stopping the heating, check if there is any water leakage, if so, you can use raw tape to tighten the leak and contact a professional to repair it.

2. Cleaning of radiators.

When cleaning the surface, do not use steel wool or hard materials, as it is not easy to destroy the surface coating. It is recommended to clean the surface of the radiator with a towel moistened with water, or use mildly alkaline soapy water to clean it.

If it is a user who has installed a boiler by himself, he can not worry, if it is a user of central heating, the private discharge of water will reduce the amount of hot water inside, and many communities do not allow users to release water privately, and many heating regulations have regulations, users should properly use and maintain heating equipment, and can not install water discharge valves, exhaust valves or heat exchange devices in the indoor heating system without authorization, nor can they change the heating pipeline system at will, nor can they install circulating pumps, etc., and cannot change the way of using heat. Failure to do so will result in a fine for non-compliance.

How do you get the heating at home if it's not hot? Will you release water? Do you know that it is useless to put water.

The specific method of venting the heating is not hot as follows: eachRadiatorsThere is a manual exhaust valve, the user can gently loosen the manual exhaust valve, hear the exhaust sound immediately stop twisting the exhaust valve, if there is a steady flow of water out, the exhaust valve can be gently tightened. After exhausting, if the radiator is still not hot, you should ask a professional to find out the cause and help solve the problem, and do not blindly discharge water.

There are many reasons why the radiator is not hot, and the water can not be released without authorization, if the water is released without authorization, it will lead to the loss of water in a certain link in the system, resulting in the change of pressure in the heating system, and the loss of a large amount of hot water in the pipe network, which leads to the radiator becoming less and less hot.

In addition, the water in the radiator has high temperature and high pressure, and it also contains chemicals that are harmful to the human body, so it is best not to let the water in the radiator out of the radiator at will.

First, the radiator accumulates a large amount of air, which will cause the heating to not be hot, open the heating valve and release the gas Second, the radiator is blocked or the heating system pipe is blocked Third, the pressure of the heating system is insufficient Fourth, the radiator pipeline installation is unreasonable, and the installation link is improper, you can find a professional installation pipeline company to deal with it.

Heating water discharge: It refers to the sudden drop in the temperature of the radiator during the normal heating process, and it is necessary to open the closed heating system and solve it by releasing a little water. The possible reasons are as follows.

1. The most likely reason is that there is air in the radiator, which affects the hot water circulation. At this time, first open the plug at one end of the radiator and release the air in the radiator. Prepare a small basin in advance, ready to catch the water that flows out of it.

2. It is also possible that there is a filter near the water supply valve of the radiator, which is blocked by impurities in the water and affects the flow rate of hot water. You can take it apart and wash it. It is necessary to prepare a wrench in advance.

Before disassembling the filter, close the heating water supply valve and return valve, and prepare a small bucket to receive water.

3. If the above methods still cannot increase the room temperature, you can try: adjust the valve knob to the maximum (control the three-way valve of each group of radiator switches to close). Or install a small circulating pump to increase the flow rate of heating hot water.

4. If you use a wall-hung boiler for heating, you can try to increase the temperature of the heating water to see if you can increase the indoor temperature (the floor heating is controlled within 55).

1.There is too much gas in the radiator, blocking the pipeline, and the radiator will not be hot locally.

Solution: At this time, the air release valve on the side of the radiator should be opened, and the accumulated air should be slowly drained until the hot water is released. If the valve fails and the disc falls off in the seat, blocking the heat flow channel, the valve gland should be opened for repair, or the malfunctioning valve should be replaced.

2.The heating is not well regulated.

Reason: In a single-family household, if the radiator is hot on the top and not hot on the bottom, the reason is likely to be that the heating adjustment is not in place.

Solution: It is necessary to adjust the indoor radiator, and the valve of the first group of radiators entering the household can be opened smaller if the indoor heating is connected in parallel, and the radiator valves after that are opened larger in turn.

3.Heating system pipes are clogged.

Reason: If the heating system pipes are blocked, the radiator will naturally not heat or partially do not heat.

Solution: When this fault occurs, the radiator should be cleaned, or the radiator blockage point should be judged, and then the pipe should be disconnected, and the dirt in the pipe should be removed or the pipe section should be replaced.

Look carefully, there is a small screw near the joint of the heater, it is not easy to twist by hand, use pliers to clamp and twist hard, loosen it, you don't need to unscrew it, just find a small basin to catch it... Heating water doesn't cost money, but it's toxic, so don't use it as tap water.

If there is a gas release valve, you naturally know how to do it, I will talk about the situation that there is no air release valve, you first close the entrance valve, and then find a pipe pliers to open the upper plug of the heating and replace the air release valve, and release the air until the hot water is OK when the heating comes every day.

If it is determined that it is not the reason of the heating company, you can unscrew the air release valve at the end of the heater, and let the air or water go for a few minutes, which is generally fine. It is not possible to contact the property or ask the heating company.

Judging from the situation you described, it seems that there is a blockage and no circulation, it is best to drain the water thoroughly and then exhaust the water to try, if it is not hot, you can only ask a professional to check the pipeline.

It is better not to put water because it will cause the water pressure of the heating company to be too low, and hot water cannot be provided to the residents for heating.

The radiator** should have a small screw, unscrew it, put some water from there and let it heat up for a while.

How do you get the heating at home if it's not hot? Will you release water? Do you know that it is useless to put water.

The old-fashioned one side has a valve that can be unscrewed, and it is easy to rust after a long time, and it is difficult to screw.

Close the outlet valve, open the small valve on the side of the heater and connect it to the sewer directly down the drain.

Anyway, I haven't used it. Usually you use air conditioning.

1. The heating system is blocked.

You can first touch the heating pipe with your hand, if the pipe is not hot, the heating system is blocked. There are two types of blockage, one is that the top floor residents close or partially close the pipe valves, and the other is that the heating system has not been maintained and maintained for many years, and a large amount of scale and sediment accumulate in the pipes, causing the pipes to be blocked.

2. The boiler pressure supply is insufficient.

After ruling out the cause of the blockage of the above system, you can touch the air inlet one by one with your hand to see if it is hot, if it is not hot from the air intake, it means that the boiler pressure supply is insufficient.

3. The service life of the heating is very long.

Considering the reasons why the heating is not hot is also the long service life of the heating, the fouling of the inner wall, and the thermal resistance.

Increase, the water flow is not smooth, resulting in the heating is not hot, you can choose to clean the scale inside the heater, or you can replace the radiator with a new one.

Usually there are two water valves in a heating system, one to control the inlet water and the other to control the return water. If there is air ingress, you can open the air release valve and exhaust until the hot water comes out.

The radiator water is too much but affects the heating supply, and the heating period can be put once or twice, and the heat may be related to the failure to clean the filter screen in time or the radiator return water pipe is not smooth.

Heating system reason: Check whether the heating system is blocked, you can first touch the pipe connecting the heating with your hands, if the pipe is not hot, it may be that the heating system is 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.

Air blockage in the heating pipe: Check if the flow rate of the system is too low or the air content of the circulating water in the system is too large. 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.

Man-made reasons: The heating is not hot due to man-made reasons, such as the user's disorderly degassing, 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 many factors such as the product itself, installation and after-sales service, and the user's usual use habits.

There is air in the heating pipe or radiator, the water cannot be completely circulated, and when you release the water, the air is also discharged together, so the water will be hot! The principle is simple! The cleaner the air exhaust, the better the heating effect!

The heating pipes in the home have not been used for a long time, and there is a lot of cool water and air left in them, which needs to be discharged in order to allow the heating company's water supply heat to enter the pipes in the home.

It may be caused by gas in the heating return pipe of your home, 1. Close the valve of the return pipe (if it is rusty, don't screw it hard, find some gasoline or something to moisturize, it may take a few hours), release the water until the heating becomes hot.

2. Open the valve of the return pipe, close the valve of the inlet pipe, and release the water until the return pipe becomes hot.

3. Open the inlet pipe valve, and finally, confirm that the inlet pipe and return pipe valves are open.

If it is not hot, you can observe it for a while to see if it is still hot, if it is not hot, please explain how you put the water, maybe I can help you.

Hello, dear, why does the heating heat if the water is not hot. The answer for you is as follows: 1. There is too much gas in the radiator, and there is too much gas in the radiator, which blocks the pipeline, and the radiator is not hot locally.

At this time, the air release valve set in the system should be opened for air deflation. If the valve fails and the disc falls off in the seat, blocking the heat flow channel, the valve gland should be opened for repair, or the malfunctioning valve should be replaced. 2. The pipe is connected to the wrong heating system, and the water supply and return pipes of the whole building are just reversed, or all of them are on the water supply (or return) pipes, so that the normal thermal circulation line can not be formed, which may be the reason why the radiator part is not hot.

4. The installation of the pipeline slope is not in line with the unreasonable installation of the pipe of the scattered heating system, which causes the air lock inside the pipeline, which blocks or reduces the circulation cross-sectional area of the pipe section and causes local heat. At this time, the slope of the pipe section should be adjusted to meet the slope and slope direction of the design requirements.
