    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.

    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.

    The number of radiators is insufficient.

    If the heating system of the radiator is not abnormal, and the indoor house area is relatively large, then the reason why the house is not hot is generally caused by the insufficient number of radiators. At this time, it is necessary to install radiators of the same size and model in suitable places in the house.

    If the radiator is installed in the inside of the house, the cold air will penetrate through the gap in the window without hindrance. Radiators are generally unable to heat the cold air in the house, so the heating rate in the house will become slow, or the heating temperature will not rise, and the phenomenon of uneven heat and cold will occur. In this case, the radiator should be modified to the appropriate position, in general, the radiator should be installed under the window, or installed at the doorway.

    The radiator is half hot and half cool

    The most common cause of this problem is that the water supply and return of the radiator are reversed. At this time, the connection to the radiator that we often see in our home is reversed, and there is a situation where the radiator is hot on the top and cold on the bottom.

    We can adjust the installation of the radiator for the water supply and return. Since the installation method of the radiator in our home is the lower supply and lower return type, we generally do not use the pipes at this time. Because of the moving pipes, it is difficult to retrofit them over a short distance.

    At this time, it is recommended that you close all the valves of the radiator, unload the water, and then remove the radiator. After that, change the connection position of the water supply and return, or buy a new radiator and install it according to the requirements of the water supply and return.

    Many homes have started to use radiators, so the indoor temperature will be relatively warm. However, there are also some families who may encounter the situation that the radiator is not hot, which will definitely affect the normal life of the family. Let's follow the golden flagship flag brother to find out.

    One. The most common and simplest is because the valve is closed, as long as the valve is turned on, the hot water will circulate, of course, this is a relatively low-level mistake, but it is more common.

    Second, there is air in the radiator to block the flow of water, and the radiator can not fully get the circulation of hot water and can not dissipate heat. The solution is to deflate through the exhaust valve or run air.

    3. The pipeline water flow route of the radiator is down and down, so the hot water in the radiator will be excluded if it can't go up, so that it will be hot at the bottom and not hot at the top. The reasons for this situation: 1. The installation of the radiator is reversed, the radiator is installed on the top with a water retainer, and the bottom becomes straight, and the hot water is all circulated from below, and the water flow with the water retaining sheet cannot be exchanged, resulting in the radiator not being hot.

    Half of the radiator is cool, and half of the heat is also the reason for the water barrier. 2. There is no water retaining sheet, the water pressure is too high, the cold water and hot water barrier have been washed out, and the cold water above cannot be returned. However, this situation is relatively rare, and the solution is to open the inlet valves not too much.

    3. It is caused by too much air on it.

    Fourth, the front of the radiator is hot, and the back is not hot? The layout of the home pipe is a single pipe in series, and there are many cases in which the radiator is turned off, and the rest will not be hot. If the inlet water temperature is 75 degrees, it will become 65 degrees or 55 degrees after passing through the first group of outlets and then enter the second group, and the second group of outlet water will become between 55 degrees and 35 degrees, and finally the radiator will basically have no temperature.

    The best solution is to re-run the pipe, and then add a circulating pump. Most of the cases that arise are done by inexperienced or careless people.

    Fifth, the valve is not adjusted well will make the radiator in the parallel pipeline uneven between heat and non-heat, the pipe is not thick enough, and it will not be hot if it does not meet the radiator standard, and the pipe below the room of 100 square houses needs 6 points is enough, but the minimum water flow rate should reach h 49 kg. 180 or so bungalows need 1 inch of pipes.

    Sixth, if the radiator is not steam, then it is not hot to go up and out, if the pipe and the radiator riser are vertical, there may be a little temperature, otherwise it will not be hot, the principle of non-heat is the automatic convection of hot water and cold water, hot water rises, cold water sinks, so the radiator is not hot. The solution is to change the radiator pipe to go up and down, or down and down.

    1. If the radiator is not hot, it may be that it has not been properly stored for a long time, there is a blockage in the pipeline, and there is even a problem of water leakage, which will lead to the water circulation is not particularly good, which will affect the radiator and the heating effect will not be hot.

    2. If the pipe is hot, but the radiator is still not hot, it is necessary to consider that the temperature control valve is not opened. In the early stage of heating, this step needs to be checked, if it is found that the temperature control valve is not opened, the radiator cannot get hot.

    3. If the heating valve is opened, but there is no hot problem, it should be considered that there may be air accumulation in the radiator, resulting in air blockage, which is also the most common fault problem. Sometimes, when the radiator is inspected, it is found that it is blocked by some debris, and the circulation is not good, and it will not heat up.

    The first thing to check if the heating is not hot is whether the valve is opened. Due to the residents of the newly built community or the first-time home using the heating equipment, there is a high chance that the heater valve will not be opened. The heater valves are all adjusted before leaving the factory, basically only adjusting in two directions, opening when the handle is parallel to the pipe, and closing when it is rotated 90 degrees vertically.

    The valves cannot be fully opened, which has a great impact on the heat removal effect of the heater.

    In the initial stage of heating, there is a large amount of raw air in the heating pipe, and the internal air pressure is too high for hot water to enter the water pipe. Therefore, if the air accumulated in the duct is exhausted and the air pressure is reduced, the hot water will naturally be drawn in and a smooth circulation will be achieved. Each radiator has an exhaust valve, such as a screw, at the end.

    Loosen the exhaust valve, gently block the water in the radiator with a towel so as not to splash on the dirty wall, and expel the air until a steady flow of water comes out. Especially when screwing the exhaust valve, please be careful not to use too much force.

    Some users at the end or bottom of the central heating are not hot due to insufficient water pressure and insufficient circulating power, which affects the circulation of hot water, and sometimes drowning is not hot. If the heat is not hot due to insufficient water pressure, you can contact the heating company or real estate to solve the problem. It's really a hassle that the heater isn't hot, but don't worry too much.

    Before repairing, figure out why it is not hot, and prescribe the right medicine, I believe everyone can do it. A word of caution here is that you should not disassemble the heater without permission. Prepare tools such as wrenches, dry cloths, water containers, soft brushes, etc., to find the filter unit accurately.

    Generally speaking, the entrance pipe in the corridor, the back of the entrance valve, and the plug with a downward slope are the filters.

    Before dismantling begins, the water supply valve and return valve of the pipeline should be closed. Gently unscrew the lid with a wrench, stop for a while, and wait until the air pressure in the pipe is exhausted, and then it can be completely removed. Once the filter is removed, you can visualize the specific situation of the filter.

    Place in prepared clean water and rinse off with a soft brush. After complete cleaning, reverse the installation and open the ** and water change valves in turn. At the same time, the filter screen belonging to the global warming system has the same shape and operation method in front of the user's indoor water collector.

    The room heating system can be fully cycled once for about 20 minutes. If the user feels that the heating effect is not good during the heating season, it is best to choose it in the summer to clean the filter. First of all, contact the heating housekeeper, ask if there is water in the pipe, remove the filter after the implementation of the situation, Jinan Heat Group will arrange experts to clean the user's filter every year to ensure the heating effect of the user's home.

It is possible that the reason for the small water pipe is that the water circulation is slow and the heating is not hot, the first group of heat is the front end of the water inlet and the second group of heat at the end will definitely be lower, you can change the pipe to a thicker point to accelerate the water flow and increase the heat.
