The radiator is hot, but the room temperature can't rise? It turns out that these details weren't done well

There are different materials, different sizes, different lengths, and different styles of radiators. The most critical factor is the heat dissipation of the radiator. The heat dissipation of different brands of radiators is different, which is why the same The reason for the different size of the radiator.

The climate in winter is getting colder and colder. Not only does the temperature drop, but the indoor temperature also drops sharply. Fortunately, there are many heaters now. Many people have radiators installed in their homes. Once there is a problem with the radiator, it is usually blocked inside and it is not warm.

But some radiators are hot to the touch, but the indoor temperature is not enough. Why is the radiator hot, but the room is not warm? What can be done without wasting heating?

The radiator at home is hot, why is the room so cold?

It is normal for a household radiator to heat up, but there are many reasons why it is not hot. If the vertical radiators heats up, why is the room not hot enough?

Horizontal Radiators

01, the heat dissipation of the radiator

There are different materials, different sizes, different lengths, and different styles of radiators. The most critical factor is the heat dissipation capacity of the radiators. Different brands of radiators differ in heat dissipation, which is why the same The reason for the different size of the radiator.

Our column radiators need to be fixed on the wall, which will affect the installation of some furniture. In the actual radiator heat calculation of 110W-130W per square, it can be seen that there will be different heat standards for different apartment structures. In some special rooms, for the placement of furniture and cost control, users are willing to reduce the heat of the radiator at the expense of the cost, but they do not realize that the impact of this is that the room has insufficient heat and cannot reach the set temperature for a long time.

There used to be elderly users who had a relatively economical life. The children installed a radiator system for them, and they also stipulated that they must use heating. Unexpectedly, the elderly in the 40-square-meter guest restaurant only turned on a radiator. The reason is that the temperature is enough. In fact, the elderly wear thick clothes at home. In fact, the radiator is not enough to supply the required heat to the room.

02, the room is not well sealed due to humidity

When buying a house, we will always consider the issue of ventilation. To avoid the house being too stuffy, reasonable ventilation is needed, but this does not mean that the house has poor airtightness. Some houses have poor airtightness, and the location of the house is not easy to see the sun and is easy to get wet. The air is aggravated, no matter it is not enough to put a few radiators, so the airtightness of your own doors and windows needs to be strengthened again!

03, valve control of radiator

There are two types of heating radiator valves, one is a mechanical manual valve, and the other is an intelligent control valve with a thermostatic head. The mechanical control valve directly controls the water supply of the radiator through the on and off of the water supply, and cannot adjust the water flow size. The advantage is that the service life is relatively long and the failure rate is relatively low; the automatic thermostatic head valve is through the internal temperature package sense The temperature effect controls the water supply flow of the radiator. There is a scale on the valve to adjust part of the temperature. The disadvantage is that the thermostatic head has a life limit and a higher failure rate.

When using automatic thermostatic head valve control, if the thermostatic head fails, the flow of the radiator cannot be better controlled, or even the problem of the water flow of the radiator cannot be opened, which will cause the radiator to fail to heat the temperature. The water flow adjustment of the radiator is more critical, which can easily lead to the phenomenon of high temperature of some radiators and low temperature of some radiators, resulting in uneven heat dissipation.

04. The position of the radiator is incorrectly installed

The location of the radiator is not determined randomly. Professional designers generally recommend that the radiator be placed on a wall with windows. This is where cold air is likely to appear. Hot and cold convection makes it difficult for the indoor temperature to rise.

But don’t put it at the door of the room. Although it is also a place where cold air can easily come in, the hot air flow from the radiator is also easy to lose. Between the boundaries of rapid hot and cold alternation, family members are prone to catch colds, and people with rhinitis are prone to sneezing!

The location of the radiator is critical

The best installation height of the radiator is about 20cm away from the ground. The air in the convection process heats up the air in the entire room. At the same time, the radiator installation needs to have a distance of 3-4cm from the wall, and the pipe height should be about 150cm to ensure the air movement around the radiator to achieve the best heat dissipation effect.

Installed under the window

For rooms with a small area like a bedroom but with high requirements for heating comfort, it is generally recommended to install the Horizontal Radiators under the window, which mainly plays the role of rapid heating and even room temperature.

increase the heating response speed

The heat exchange between the surface of the vertical radiators and air, and between air and air are all convective heat exchanges. In the process of convective heat exchange, the greater the temperature difference between the heated object and the heated object and the higher the air velocity, the higher the heat transfer rate in the heat exchange process. big.

The thermal conductivity of the windows and doors in the building is very large (easy to dissipate heat), and there may be a certain amount of cold air infiltration in the gaps. Near the outer windows is the lowest temperature place in the room. Place the radiator at the position where the temperature difference is the largest under the window, and the air flow speed is the largest, so that in a unit time, the radiator can emit the most heat to the room and make the room heat up quickly.

Balanced room temperature

The cold air in the room mainly comes from doors and windows. Due to the high density of low-temperature air, the cold air entering the room will linger on the ground, which just conflicts with the temperature field that people prefer. Therefore, isolating or heating these cold air will greatly improve heating comfort. In addition, due to the intervention of cold air, the hot air above the radiator is cooled and flowed, which can reduce the baking feeling when the user is standing next to the heated radiator while ensuring heat dissipation.
