What s going on with the radiator temperature being high and low

In the heating season, users often report that the radiator is not hot, the top ten brands of radiators or the radiator temperature is very high, but the indoor temperature is not up to standard, or the radiator temperature is very low. So, according to the user, is the temperature of the radiator normal? Let's follow the golden flagship flag brother to find out.

In this regard, the user's indoor heating effect is actually mainly reflected in the indoor temperature, rather than the radiator temperature. If the temperature of the radiator is proportional to the change of the weather, then it is a normal phenomenon.

The purpose of heat supply is to compensate for the heat dissipation of the building in order to maintain a relatively stable room temperature. The amount of heat dissipated in a building has a lot to do with environmental factors such as outdoor temperature. The lower the outside temperature, the more heat the building can dissipate.

In order to keep the room temperature relatively stable, the heating system must supply the right amount of heat. The lower the outside temperature, the more heat is supplied. Our heating system now automatically adjusts the temperature of the water supply according to the weather conditions.

The colder the weather, the higher the temperature of the water supply, and the greater the flow of circulating water. The hotter the weather, the lower the temperature of the water supply and the smaller the circulating water flow. The surface temperature of the radiator is sometimes high and sometimes low, which is related to the weather conditions, and if it corresponds, it is normal.

Confirm that the effect of heating is mainly reflected in the room temperature, not the radiator temperature.

What should I do if the temperature of the radiator is sometimes high and sometimes low? Is it normal? What happens if the temperature at home is not up to standard?

There are two main problems with this.

The first is whether the temperature of the heating unit is constant.

There is also a need to make sure that the radiator is unobstructed and not blocked.

These two aspects are the reasons for the production of radiators, and the temperature is sometimes high and low.

The temperature of the radiator gas sheet is high and low, what is going on? This is because the temperature during heating is sometimes high and sometimes low, so the radiator will also be wet, high or low.

The radiator in the home is hot but the indoor temperature is not high, which may be caused by this situation:

1.The insulation effect in the house is not good, and the heat loss is relatively large.

The house may have lived for a long time and experienced too much wind and rain, resulting in deformation of doors and windows, not closing tightly, and you can feel the cool breeze blowing when you are close to it, and the insulation is not good, and no matter how much heat you have, you can't retain it. In this case, it is recommended to replace new doors and windows, preferably with broken bridge aluminum, which is relatively strong, not easy to deform, and has a particularly good thermal insulation effect.

2.The number of radiators is small, but the size of the house is large.

The radiator is particularly hot, but the number of radiators is small, the house area is large, the house is relatively high, the indoor temperature will not be high, and the heat emitted by the radiator is not enough to drive such a large room.

3.The location of the heating installation is not reasonable.

If the radiator is in the position of the window, it will form a heat cycle around it, which is equivalent to the circulation of hot air in the house, so that the temperature of the house will rise relatively quickly. If the location of your radiator is in a corner of the house, you can consider changing the location.

4.The heat dissipation of the radiator is not good.

Some of the radiators used in the home are still the kind of iron before, the use of time is relatively long, the radiator has a thick layer of rust, these substances seriously hinder the diffusion of heat energy, even if the radiator is very hot, the indoor temperature will not be very high, or replace it with a new radiator, which not only saves the use of heat energy, but also warms our home.

5.Whether your neighbors are heating or not.

There are several upstairs and downstairs, if only one of you is heating, then the heat energy of your home will spread around, so that the temperature of your home will definitely not go up, and it is best to convince them to heat collectively, so that they will benefit from each other.

This shows that the heat dissipation area of the radiator is small (the number of radiators is small), the space area is large, or the location of the radiator is not convenient for heat dissipation, the space sealing performance is poor, and the indoor temperature is low.

If the heating is hot but the indoor temperature is low, it may be that there is a problem with the indoor insulation, so you should first check the tightness of the doors and windows, and if necessary, replace them with double insulating glass, or simply install double windows.

If the heating in the house is hot, but the indoor temperature is low, you have too few radiators, or too little floor heat. Or if your house is not warm, you can check it against it.

If you're just starting to get heated, you'll feel this way. 1.It takes a while for the indoor temperature to rise.

Before heating, the temperature of the physical and indoor items of the house has been decreasing as the temperature drops. When the heating starts, the indoor temperature will rise, but it will not feel warm until the temperature of the indoor items has risen (commonly known as hot through).

2.People's subjective feelings are not very reliable, the same indoor temperature, if the humidity is relatively high, people will also feel cold.

The heating is very hot, but the indoor temperature is very low, which may be caused by the poor sealing of the house or the strong guarantee.

Why is the heating hot? But low indoor temperature? It may be that your indoor space is relatively large and the heat supply of the heating is not enough, or it may be due to the fact that your indoor temperature is not tightly closed, resulting in low indoor temperature.

The low temperature in the heating room should be relatively large, and the radiator is small relative to the room area, and it is also possible that the room is not well sealed.

Why is the heating hot, but the indoor temperature low? I think the indoor temperature of the radiator hood is low because the heat of the heating is not yet hotI think the heating is hot, and the indoor temperature is low because the heat of the heating has not yet been fully dissipated into the room. After a few hours, the indoor temperature in the house will become high.

It could be that the weather is too cold, or the pipes in the heating are blocked.

The radiator is half hot and half not hot, there is a sound of water inside, or the temperature of the radiator is not as high as someone else's.

Solution. In this case, there is air in the radiator group, and the air valve needs to be opened to release the air until there is water flowing out. The method of deflation, on the upper side of the radiator, the toilet heater is at the top, there is a deflation valve that can be opened and adjusted (the opening method is different), after opening, the air in the heating is released, and the heating can become hot, and it needs to be deflated many times according to the situation until it is exhausted. Note:

The exhaust valves are all arranged on the upper part of the radiator, and the exhaust valves near the ground will not be the exhaust valves.

The radiators in the home are not hot, but the pipes have a certain temperature.

Solution. In this case, in order to prevent the radiator from corroding, the grouped valves of each group of heating are closed before the end of the heating of the previous year, so as to prevent the heating from entering the air and make the heating rust and rot, and then open the sub-valves of each group of heating.

The heating temperature in the home is different, some are very hot and some are not.

Solution. In this case, the main reason is that the flow of hot water in each heating is uneven or the internal resistance distribution is uneven, and the water inlet valve of each radiator needs to be adjusted separately.

The radiators and pipes in the home are not hot.

Solution. In this case, it may be that the main valve of the heating is closed, just check the supply and return valves and confirm that they are open.

All the heating in the home is close to the heat of the entrance door, and the farther away from the entrance door, the lower the temperature.

Solution. Turn off a group of heaters, all the heaters will not be hot, this situation is caused by the radiator group in series, resulting in a high temperature at the inlet end, as the flow direction of the radiator group is getting lower and lower, the radiator will definitely not be hot. In this case, you should contact a professional maintenance personnel as soon as possible.

The neighbor's radiator is hot, and the overall radiator in my house is not hot.

Solution. It may be that the flow rate of the valve entering the house is too low. If the radiator is not hot, it is likely that the valve is too small, at this time, as long as the valve is unscrewed, the water flow increases, and after a period of time, the radiator will become hot.

Special Tips. The hot water in the central heating pipeline is a medium that conducts heat energy in a fully closed circulation system under high temperature and high pressure, and in order to prevent corrosion and rust of pipelines and valves and ensure the smooth circulation of water supply and return, a certain amount of chemicals are added to the water, and the water quality does not meet the domestic water standards. The use of hot water in the radiator will damage your health, and at the same time, it will also cause serious water shortage in the heating pipeline, make the water loss of the heating pipe network system serious pressure imbalance, resulting in the partial or full heating system can not be stable heating, affecting the normal heating of other residents. Therefore, unauthorized access to the water in the heating is harmful to individuals, communities and heating companies, and I believe you will not do this.

All kinds of heating systems have been turned on, and when entering a new heating period with confidence, many users find that the heating in their houses is not hot, and they don't know how to solve it. What to do if the heating at home is not hot, it encyclopedia HVAC experts introduced that the heating is not hot is divided into many different situations, some are all not hot, some are partially hot, and some are hot at the bottom and not hot at the top.

In the event of this failure, the valve before the heating is generally closed, and the supply and return valves can be opened. If it still doesn't work, it should be that the radiator is clogged, and you can find a professional cleaning person to clean it.

1. Gas accumulation. 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, unauthorized modification: If the above methods cannot be solved, then the radiator or pipeline may be blocked or seriously installed unreasonable.

If the heating is not hot, it is not necessarily broken. If it is a heating in the north, then the heating may not be hot or not, and if the heating temperature set by the heating company is not hot, then the temperature in the user's home will not be high. If it is determined that it is not the problem of the heating company, then it may really be that the heating is broken, and it is necessary to pay close attention to the dust to investigate the heating problem and solve the heating demand as soon as possible.

The above is the answer to the question "Is the heating broken if it is not hot", and the next thing is the supplementary content about the heating, interested viewers are welcome to continue**.

1. The heating itself is faulty: if the heating itself is blocked or leaking, there may be a problem that the heating is not hot, and the radiator needs to be repaired in time to solve the problem of the heating not being warm.

2. Heating pipe failure: If the heating pipe is faulty, there may be a problem that the heating is not warm or blocked, and the heating pipe is relatively large, so it is better to let the heating company come to repair it for its own safety.

3. The heating temperature is not high: If the heating temperature of the heating company is not high, which affects your normal life, then we can also complain to the heating company at this time and ask the other party to increase the heating temperature.

4. Auxiliary heating of air conditioner: If the air conditioner does not have a heating function, it can also use the auxiliary heating function to produce heat. However, the auxiliary heating function of the air conditioner is not essentially heating, so the auxiliary heat of the air conditioner will not warm up the whole room.

Summary. 3. There is air inside the radiator: the air blocks the pipeline and the radiator is not hot.

Kiss. Household air energy heat pump heating radiator with high temperature above and low temperature below Reason:

1. Wrong pipeline connection: the water supply and return pipes of the heating system are reversed to the water supply and return pipes of the whole building.

2. The installation of pipeline slope is unreasonable: the air lock inside the pipeline is generated, causing local heat failure.

3. There is air inside the radiator: the air blocks the pipeline and the radiator is not hot.

Solution: Connect the wrong pipe correctly in time, and pay attention to the connection interface to be sealed, otherwise the water leakage will be very troublesome in the later stage.

In this case, the insulation of the house is relatively poor, and a large part of the heat emitted by the radiators escapes to the outside.

This situation is because the house is not well sealed, and there is cold air coming in all the time.

The indoor temperature is warm and smooth, and the temperature is rising today, but if the indoor temperature is relatively low, it may be that the number of radiators installed is too small, or the location is wrong, and it should be readjusted. Letter and land key.

1. During the heating period, the water inlet valve is opened, the return valve is closed, the circulating water for heating does not flow, and the water in the radiator becomes cool after heat dissipation. The room temperature will slowly decrease, and if the room temperature drops below freezing, the radiator will freeze and crack.

2. The return valve is closed, the circulating flow rate is reduced, the temperature of the radiator is reduced, and the indoor temperature of the heating room is reduced.

3. In order to ensure the normal heat dissipation during the heating period, the heating water supply valve and return valve should be opened to the maximum to ensure the flow of hot water.

4. If you are independent heating (wall-hung boiler, coal-fired boiler, etc.), and the room temperature is unbalanced, you can appropriately adjust the degree of opening of the valve of a certain group of radiators, and appropriately reduce the degree of opening of the radiator heating valve in the room with high temperature, so that more water can flow to the room with low temperature.

5 If you are using central heating, you reduce the degree of valve opening, which is equivalent to sending more hot water into other users' homes, such as your upstairs neighbor's house, and your room temperature will be lowered.
