How to choose a home radiator? How do I connect a radiator?

Steel radiator with its light weight and high efficiency, material saving and energy saving, beautiful and environmental protection of the significant characteristics, both in China and in Europe, it has become the mainstream, in Europe, steel radiators, especially steel plate radiators occupy a dominant position.

We have analyzed the main advantages of steel plate radiator and the following machine characteristics:

1. Good thermal performance Steel plate radiator can solve the problem of indoor temperature uniformity of other radiators, because only steel plate radiator can obtain good thermal performance, that is, 30% radiation heat dissipation, 70% convection heat dissipation, so as to obtain the highest thermal comfort, if the radiation heat dissipation is too large to cause damage to the indoor furniture surface, the indoor heating rate will also slow down, and the heat loss is large. Of all the types of radiators, only the steel plate radiator achieves a higher convection heat dissipation.

2. High thermal efficiency and fast heating speed The heat dissipation efficiency of the steel plate radiator is the highest among all forms of radiators, with a smaller volume to achieve the best heat dissipation effect, and no longer need a heating cover, to minimize the occupation of indoor space, improve the utilization rate of the room. Due to the small water storage capacity of the steel plate radiator, the boiler heats up quickly, the indoor heating is also fast, and the thermal inertia is small.

3. Low production cost, stable product quality, strong market competitive advantage High degree of production automation, stable and reliable product quality; High production efficiency, low relative cost and strong market competitiveness; The welds are the fewest and the high-quality steel is the least affected by damage, and the hidden dangers of leakage are the least.

4. Beautiful appearance, high pressure, matching with various types of house decoration, no need for secondary decoration; It can withstand high pressure and can be used in high-rise or super high-rise buildings.

This year, China has also begun to use this steel plate radiator in a large area, especially in China's southern market (such as Wuhan, Chengdu, Changsha, etc.), in the matching heating with the wall-hung boiler, the steel plate radiator has occupied a dominant position in independent heating, in Hefei, the steel plate radiator is also used in central heating on a large scale.

The internal corrosion of steel plate radiators is a problem that people are more concerned about. In fact, not only the steel plate radiator needs internal anti-corrosion, but also the radiator of other materials, and the entire heating system also needs internal anti-corrosion to ensure the safe operation of the system. For internal embalming, there are two ways:

The first is "passive anti-corrosion", that is, applying anti-corrosion paint to the inside of the radiator that needs to be anti-corrosion. The biggest drawback of this anticorrosive method is that it is difficult to ensure and detect whether the anticorrosive paint is effectively and evenly applied to the inner surface during the production process. The second is "active anti-corrosion", that is, the use of a closed heating system, so that the system is always filled with water.

This method is widely used in Europe, where heating technology is very developed, and the steel plate radiators used can last up to 30 years. With the continuous progress of heating technology in China, more and more closed heating systems are used in new buildings. At the same time, with the requirements of "thermal reform" work, the transformation of the old system continues to expand, and the market demand for steel plate radiators will continue to expand.

This depends on the heating situation of your home, is your home central heating or self-heating? If you want central heating, you choose steel, and if you want to heat yourself, you choose copper and aluminum.

Central heating is a kind of intermittent heating (burn for a while and stop for a while), the water storage of steel is 5 times larger than the water storage of copper and aluminum, when the heating stops heating, the larger the water storage of the heating system, the longer the heat preservation time.

Self-heating is self-burning, when the temperature reaches a certain level, the heating will not burn, the wall thickness of copper and aluminum is thin, the heat dissipation is fast, it is more energy-saving, and the corrosion resistance is good. (Excerpt from.) Vera radiator, Beijing's) ZJ

How to use radiators? What are the precautions for the use of radiators?

First: radiators and heating systems should be checked regularly, especially in infrequently visited places, to prevent water leaks from causing greater damage; Especially in the initial stages of heating and shutdown. During the week after the temperature rises, the temperature varies greatly during this time.

Due to thermal expansion and cold contraction, it is prone to water leakage.

Second: due to the large inner diameter of the radiator, the flow rate of hot water will slow down after entering the radiator, and the impurities in the water will be deposited into the radiator, resulting in the inner diameter of the radiator being reduced for a long time and the water flow decreasing; Once the heat dissipation effect is achieved, you will feel that the heat sink is not as hot as before; Therefore, radiator pipes should be cleaned regularly. You can find a professional HVAC master to do it.

It is not recommended to clean them yourself.

Third: The valve on the heating tube cannot be opened or closed at will. When a heating system is first put into operation, it is often necessary to commission it.

Each household should adjust the valve of each riser to a suitable position in time, open the manual exhaust valve of each radiator to discharge the air collected in the radiator, or open the exhaust valve of the air collection box installed on the top of the system for exhaust until each radiator becomes hot, and complete the commissioning. After the commissioning is completed, the valve should be fixed and should not be opened or closed at will.

Fourth: repeated injection of raw water will continue to corrode the inner wall of the radiator. The best way to apply this is to compensate for the lack of water in the radiator piping system.

Since the oxygen content in the raw water is almost zero after repeated high temperatures, it does not corrode the heating system. Therefore, do not dispense with the water in the radiator. Households that use steel heaters should pay attention to closing the valve in time when the heating stops so that the heating can be filled with water, which can prolong the service life of the radiator.

Some copper-aluminum composite heat sinks also require full maintenance!

Fifth: During the annual heating season, the temperature of the room where the radiator is used should be kept at 18-25, especially in self-heating homes. Do not turn off the heating system when it is warm and turn it on when it is cold.

Hot and cold environments are not only bad for human health, but also waste energy.

Be sure not to be next to the wall, leave some appropriately, do not pile too much sundries around the space for heat dissipation, do not open and close the valve at will, and do not change the position at will.

It needs to be determined according to the specific family area, and when using, we must pay attention to the problem of water supply and water, and pay attention to placing it in a suitable position.

It needs to be installed in a reasonable position, and it is necessary to do a good job of connecting the pipeline for use, and we must pay attention to the choice of style, the size of the problem, and the number of square meters.

It is best to put it in a place with a relatively large space, be sure not to put too much sundries around, pay attention to the problem of heat dissipation, but also pay attention to the follow-up maintenance problems, and do not change the position at will.

1. How to buy radiators?

1. Check whether the surface of the radiator is smooth and whether there are protruding welding points. Generally, the production management of regular manufacturers is strict, and the automatic welding and automatic spraying process are adopted, which will not leave solder joints on the surface of the radiator, and will not produce blistering or cracking during spraying. Therefore, it can also be said that the smoother the surface of the radiator, the better the quality of the radiator can be guaranteed, and the occurrence of water leakage caused by "trachoma" can be greatly reduced.

2. Understand the internal anti-corrosion treatment of the inner wall of the radiator. At present, steel radiators, as one of the mainstream radiators on the market, are the most prone to water leakage due to oxidation corrosion, so the internal corrosion protection of steel radiators is particularly important. If there is no internal anti-corrosion treatment, it will be easily oxidized and corroded during use, resulting in "trachoma" and water leakage.

3. Weigh the weight of the radiator, in the case of the same heat dissipation, the heavier radiator is generally made of better steel, and the pipe wall of the radiator is relatively thick.

4. Knock on the radiator to distinguish the sound, the general material is better, and the sound emitted by the radiator with a thicker pipe wall is more crisp.

2. The precautions for the installation of radiators are as follows:

1. It needs to be installed in a reasonable location.

The radiator will generally be installed under the window sill, which can not only increase the utilization rate of the room, but also help the indoor air to produce convection, maintain the balance of room temperature, and heat the air from the window to play a role in indoor cold protection, that is, it does not affect the placement of furniture, and the second is to effectively block the discomfort caused by the cold air entering the room. In terms of aesthetics, space and heat exchange, it is a good location under the window sill.

The selection of radiator installation location can follow the two principles of low and not high and priority under the window. Generally speaking, hot air rises and cold air sinks, so try not to be too high when installing radiators.

2. Avoid using radiator masks or objects to cover radiators.

For the sake of beauty or convenience of life, some families install radiator masks on the outside of the radiator; Some people also like to place sofas, furniture, etc. next to radiators, which are not advisable. Shielding or surrounding the radiator will not only affect its heat dissipation effect, but also bake furniture such as sofas, which may cause the furniture to twist and crack in the long term.

3. After the radiator is installed, it should be pressed and tested.

It is also necessary to complete the installation of radiators and accept the safety tightness. After installation, a water injection pressure test should be carried out to ensure that there are no leaks. After the pressure test, a pressure gauge should be installed at the end for the pressure test.

At the end of the pipeline pressure test, the insulation operation of the pipeline should also be done to eliminate the possible risks in the later operation of the system.

This kind of very good recommendation, if you want to choose, I recommend the Senlat brand, in fact, I have been in contact with some of the radiators of this brand before, and when installing them at home, I have also chosen their radiators, and I have used them for a few years, I feel that the texture is still very good, and the quality is also guaranteed, and the room is very hot after turning on the heating in winter. Satisfied with mine? If satisfied.

Radiators split into columns, iron and steel? The appearance of the general column iron is not beautiful, but his heat dissipation effect is better? Steel with heat sink is good! It is hot to the touch without a heat sink, but the heat dissipation effect is not good! The use of column iron is long, the use of steel is short, he is easy to rot?

1. When using the radiator, you can turn off or turn down the temperature of the radiator in the uninhabited room. If the housing area is large, there are many rooms, and the population is relatively small, then the radiator valve in the room that is not occupied or used infrequently can be completely closed or reduced.

2. This is equivalent to reducing the heating area, which not only saves energy, but also accelerates the heating temperature rise in the normal use of the space, reducing gas consumption.

3. Users can choose the installation location, heating time, heating temperature and even the style of the radiator according to the room they want to heat. However, the need to expose the bulky appearance of the room and the disadvantages of uneven heating effect are gradually becoming obsolete among home users.

Radiators are used correctly.

The use of radiators should be considered from the following aspects:

Radiator installation work.

1.The installation of the radiator has a great impact on the use of the heating in the future, the installation position of the radiator is selected by the professional master to come to the survey, this position is conducive to the location of indoor heating, which can ensure the air convection and indoor temperature in a relatively balanced manner, if it changes its location, it may cause an imbalance in indoor temperature. In addition, once the pipe or radiator is moved, it is easy to cause leakage, which will not only cause economic losses, but also may harm health.

Therefore, although the installation of heating is simple, once the location is selected, it cannot be easily changed.

2.If there is more hot water missing in the pipeline, it is necessary to supplement the cold water to maintain a certain pressure in the pipeline system, and the water temperature in the pipeline will drop if the hot water is lost, and the heating effect will be worse.

3.Try to maintain a certain amount of heat dissipation space near the radiator in the room, and do not pile up sundries on top of the radiator or in front of the radiator, otherwise it will affect the heat dissipation effect of the radiator.

4.Before the radiator is run for the first time, it needs to be debugged, specific to each valve, and the air collected in the radiator is discharged until each radiator is heated up, and there is no leakage to basically complete, once the debugging is completed, the valve can no longer be artificially switched.

Radiators are used for wall-hung boilers, wall-hung boilers are energy-saving, first of all, the room temperature should be scientifically controlled, the ideal indoor temperature is 20 during the day and 15 to 17 at night. In principle, the water temperature (or return water temperature) should be lower when it is warmer, and the water temperature (return water temperature) should be higher when the weather is cold; When the weather is warm, the starting temperature difference should be larger, and when the weather is cold, the starting temperature difference should be cleared.

Be smaller. Secondly, when there is no one at home, you only need to adjust the heating temperature adjustment knob of the wall-hung boiler to the "0" gear (at this time, the wall-hung boiler is in an anti-freezing state, the water temperature in the heating is kept between 35-40 degrees Celsius, and the overall space temperature in the room is about 8-14 degrees Celsius).

In normal times, the heating valve in an uninhabited room can be closed or lowered to save gas to a certain extent. If there is no one at home for a long time or has not yet lived in it, drain the water in the wall-hung boiler, floor heating or heating to avoid freezing damage to the wall-hung boiler or the end of the heat dissipation.

At the same time, regular maintenance and maintenance should be carried out. After a few years of use, the gas wall-hung boiler will have impurities and scale, resulting in low thermal efficiency, and regular cleaning of the wall-hung boiler can extend the service life of the equipment by 3-5 years.

In addition, in addition to the above use methods, whether the wall-hung boiler is gas-saving is also related to the brand, generally speaking, users can set it at will according to the climatic conditions, which is more conducive to gas saving. During installation, the pipe layout of the wall-hung boiler is reasonable, which is conducive to the normal operation of the gas wall-hung boiler and reduces the energy loss of the wall-hung boiler.
