What is the difference between self heating and central heating?

What are the advantages of radiator heating?

Compared with traditional cast iron radiators, the advantages of insert radiators are not only aesthetically pleasing:

1. Good heat dissipation effect. The large feature of the insert radiator is that the heat dissipation effect is about 30% higher than that of the traditional cast iron radiator.

2. The quality is very stable. The quality of the blade radiator is much more stable than that of a traditional cast iron radiator.

The cost performance of the blade radiator is very reasonable, and there are many types, styles and colors of the blade radiator, which can be matched with any interior decoration style.

There are more than 200 colors such as unique angular shapes, arc shapes, bench shapes and bathroom special shapes. Moreover, the surface of the insert radiator is made of electrophoretic spray paint and plastic spray cover, which has the characteristics of smooth and clean, no edges and corners, no bumps, and no pollution.

At present, there are two types of steel radiators: plate type and column type. Steel radiators have a history of 100 years in European countries, accounting for more than 70% of the market share, and quickly entered the lives of ordinary family users after entering China in the eighties.

Steel radiator has the advantages of light weight, high pressure, low production energy consumption, beautiful appearance, many styles, many colors, etc., but it is worth noting that the steel radiator has high requirements for the water quality of the heating system, and it is easy to corrode when using the heating system with poor water quality.

Copper-aluminum composite radiator is a copper tube with anti-oxidation corrosion, which is attached to an aluminum wing with excellent heat dissipation effect, and the water flowing in the copper pipe will not cause corrosion, and the heat can be fully volatilized from the aluminum wing, which can be described as a strong combination of materials. The copper-aluminum composite radiator overcomes the shortcomings of low pressure, low metal thermal strength and poor decorative performance of cast iron radiator, and also overcomes the weakness of poor corrosion resistance of steel radiator and other metal radiators, and reduces the trouble caused by excessive water quality requirements for the system. Advantages of copper-aluminum composite:

It has a certain anti-corrosion effect and diversified plasticity. Corrosion resistance, long service life, good thermal conductivity, high efficiency and energy saving. The service life is more than 50 years.

What about the cost of radiator heating?

Instant heating, comfortable and efficient heating, initial installation cost: less than 30,000 yuan gas bill: about 600 yuan.

Radiators also have a large number of adherents relative to underfloor heating. Ms. Chang from Tianjin told us that compared with air conditioning, family members prefer to use radiators, because radiators are beautiful in appearance, high thermal efficiency, easy to install, relatively cheap, and air conditioning, more comfortable and healthy, and floor heating, heat dissipation efficiency is higher, more suitable for fast-paced office workers and young people, and there is no need to hide the pipe, you can carry out surface heating. In addition, the radiator can also be used to dry wet diapers and wet clothes, which is very practical.

Its heat source wall-hung boiler can also provide domestic hot water, saving families money on water heaters. If you drive it for 6 hours a day, the electricity bill is about 600 yuan a month.

1. The heating time of central heating is different according to different regions, which has formed a limitation to a large extent, the climate is different every year, and the time of cold arrival will not be the same every year, but central heating makes people have to wait until the heating time to enjoy the warmth; However, self-heating does not have this problem at all, and users can enjoy a warm environment at any time.

2. The time and temperature of central heating cannot be controlled by the residents themselves, and the heating temperature is hot and cold, unstable, and the user cannot adjust it by himself. Any kind of self-heating equipment can be freely adjusted and controlled, and the temperature will not be too high and too low.

3. The biggest advantage of self-heating compared with central heating is energy saving, central heating wastes a lot of heat on the pipeline, and the efficiency of self-heating is very high. In addition, the cost of self-heating is lower than that of central heating, a wall-hung boiler with rated gas consumption of cubic meters of hours as an example, if the house is heated in about 100 square meters, the room temperature is constant, and the wall-hung boiler runs for 5 hours, then the daily gas consumption is cubic meters.

If there are self-heating conditions, the self-heating effect is better, but the cost of central heating will be higher.

However, because the heated water or steam is transmitted to the home through the heating pipes, there is a loss of heat during the transmission process. Therefore, it will cause the phenomenon of temperature difference in the same building in the same community.

However, the disadvantage of self-heating is that it is significantly more expensive than central heating.

When decorating a self-heating house, it is necessary to take into account the insulation of the house, such as installing well-sealed doors and windows, installing double glazing, sealing strips, etc., so as to reduce heat loss. It can improve the efficiency of self-heating and reduce the cost of self-heating.

If the radiator has good heat dissipation, then the balance and stability of the room temperature can be ensured, and the heat can be quickly dissipated, the room temperature can be quickly increased, and the gas consumption can be reduced. It will not affect the comfort of heating, and it is also very gas-saving and cost-saving.

3. How much is self-heating a month?

Taking the heating cost of gas wall-hung boiler in Beijing as an example, if you want to use gas wall-hung boiler to heat a 2-bedroom house of 80 square meters at 26 degrees for 8 hours, you need to consume 7-8 cubic meters of gas.

If you heat for 8 hours a day for a month, then you need about 500 to 600 yuan for heating. If it runs 24 hours a day, the cost will be around 1200.

Self-heating money-saving strategy:

1) The temperature should not be too high:

When using self-heating, make sure that the temperature of the room is not too high. The temperature is suitable, so that you can not only enjoy the warmth, but also achieve the purpose of saving money.

2) Don't use it for too long:

When using self-heating, you can turn off the wall-hung boiler before going to work in the morning, or adjust the temperature of the wall-hung boiler to 20 degrees Celsius to reduce gas consumption. In order to achieve the purpose of saving money.

3) Sub-district heating:

Heat can be reduced by turning off the heating valve in rooms with less active time such as the kitchen and leaving only the living room and bedroom heating**.

What is the difference between central heating and self-heating?

At present, the mainstream radiator materials in the heating market are: steel radiators and copper-aluminum composite radiators.

The material is easier to use, depending on the water quality of the heating used, if the water quality is very poor, you can choose a copper-aluminum composite radiator, because it has super corrosion resistance. If the water quality is good, you can use steel radiators because they are beautiful and economical. It depends on their own needs.

If the home is self-heating, it is recommended to choose a radiator when choosing a radiator, the temperature rises quickly, and the copper and aluminum composite radiator with a large single heat dissipation area is selected. Master Jin said that self-heating at home is more free than central heating, and when there are people at home, you can choose to turn off the wall-hung boiler and turn it on after returning home, because the radiator made of copper and aluminum composite material heats up quickly, and it will be warm when you go home for a while, and it is energy-saving.

What material radiators are suitable for self-heating and central heating?

At present, most of them use floor heating, and rarely use radiators, so it should be a better PVC pipe to lay under the floor!

Abstract:When purchasing radiators, many factors will affect the purchase, and some factors will directly affect the purchase of radiators, such as heating methods, heating methods are the factors that directly affect the selection of radiator hall wide materials. Different heating methods will be suitable for radiator products of different materials, only to determine the heating method can choose the radiator products that suit you, so what radiators are good for self-heating and central heating?

Central heating is a heating method that transmits centralized heat sources to users through pipelines. Users who use this method for heating should not use copper-aluminum composite radiators, because aluminum is easily corroded when exposed to alkaline water. In order to protect steel boilers, heat exchange stations, pipelines and other transportation equipment, central heating usually adjusts the pH value (pH) to 10 12, which is alkaline, and chemical reaction will occur in contact with aluminum products, resulting in the loss of aluminum products.

In addition, the steel radiator waterway is larger than the copper-aluminum composite waterway, and the water capacity is more, and the heat dissipation effect is better for the users of central heating, so the users of the central heating slag basically choose the most suitable steel radiator.

2. Low-temperature heating users choose steel radiators.

The so-called low-temperature users are those who supply water with a temperature of no more than 85 degrees Celsius, and the way to test whether the water temperature is more than 85 degrees Celsius is very simple, that is, put your hand on the heater, and if you can tolerate it for 2 seconds, the temperature will be lower than 85 degrees Celsius. In this case, the user should not use the copper-aluminum composite radiator, because the copper-aluminum composite radiator is mostly heated by air convection, if the water temperature is too low, it will cause the air convection speed to be too slow, and then lead to the attenuation of the heat dissipation effect. Generally speaking, every 10 degrees Celsius drop in water temperature reduces the heat dissipation by 40%, and in this case, the heating feels hot, but the interior is not always hot.

Therefore, for low-temperature users, it is recommended to choose steel radiators, which can better ensure the heat dissipation effect.

3. Single-household heating users choose copper-aluminum composite radiators.

Self-heating is a form in which self-use residential buildings do not use central heating facilities and use clean energy to solve heating needs by themselves, including water source heat pumps, wall-hung boilers, air far-infrared heaters, gas heating stoves, etc. Single-household heating users should not use thick pipe radiators, because the thick pipe radiator has a large water capacity, coupled with slow response, it is easy to cause a waste of energy and resources, which is not conducive to energy conservation and environmental protection, and will increase the cost of heating. Steel radiators have thick waterways, so it is not recommended to use steel radiators.

In view of this situation, it is recommended to use copper-aluminum composite radiator, the thickness of the pipe wall is relatively thin, and the speed of heat dissipation is relatively fast, this is because the thermal conductivity of copper and aluminum is good, and copper is also one of the corrosion-resistant metals, choose copper as the inner wall of the radiator, and direct contact with water, can also achieve the effect of anti-corrosion, and aluminum is one of the metals with fast heat dissipation, the choice of copper-aluminum composite radiator can delay corrosion, but also give full play to the good thermal conductivity of aluminum, heat transfer is also relatively fast, can speed up the circulation of heat.

Radiators match the decoration style.

Everyone will determine the corresponding decoration style in the home decoration process, such as European style, French style, Chinese style, Mediterranean style, etc., which is the main color in the whole decoration process. Therefore, for the decoration of radiators, whether it is the model of the radiator, the size of the radiator, or even the color of the radiator, it needs to be integrated into the overall style of the living room decoration, so as to bring a harmonious and unified decoration experience.

Nowadays, most young customers will choose warm colors, so that they can live more comfortably and feel the warmth of home. Therefore, in the decoration process, we can not use the radiator that is too bright to make the color too bright, but also need to choose some warm colors, such as white, pink, light blue, etc., so as to meet people's actual needs for decoration and bring a better decoration experience.

Radiators are matched with the appropriate style.

Since there are many different styles and types of radiators in life, and even into many different models, such as steel radiators, steel panel radiators and copper-aluminum composite radiators, these radiators will be different in shape and color. Therefore, in the actual decoration process, we need to understand the shape and color of the radiator in advance, and then understand the decoration style of the sofa, TV, TV background wall and floor in the living room, so as to make the radiator harmonious and unified with the overall household appliances, so as to pursue the decoration concept of beauty.

Heat dissipation of radiators.

Since the living room is relatively large and the windows are relatively large, the heating of the living room is very important. It only needs to meet everyone's basic living needs, reach a certain temperature range, and use the least number of radiators, which is the most reasonable way to match. At the same time, we also need to understand the warmth effect of the living room, if the warmth of the living room is not good, you need to increase the number of radiators, if the insulation effect of the living room is very good, you can appropriately reduce the number of radiators.
