1. Steel or copper-aluminum composite radiator which one to choose
1. Different corrosion resistance
Copper Aluminum composite has relatively better corrosion resistance, and steel radiator needs water maintenance to maintain its relatively long working life even if it is internally anti-corrosion, otherwise the corrosion resistance is slightly worse, but the so-called slightly worse is at least 20 years. Working life, who knows what will happen to the heating form in 20 years? Moreover, copper and aluminum heating is the corrosion resistance obtained by sacrificing the thermal conductivity of certain parameters. When choosing, it depends on which aspect you focus on.
2. Different water capacity
For radiators of the same size, the water capacity of steel is significantly larger than that of copper-aluminum composite, which also causes steel The thermal inertia of the system is greater, and the holding time is longer in actual use. Once the heating is suddenly stopped after heating, the water inside will cool down a bit slower. After the copper-aluminum composite material is heated, it will heat up as it is turned on. After it is turned off, it will cool down quickly because of the small amount of water storage.
Second, how to choose heating in the south
1. Install heating and choose boiler, and consider both living and heating
In the south, heating is installed, and household heating means that the heating system of each household is independent. Therefore, the heat source must have a wall-mounted boiler that heats and circulates water through natural gas to achieve heat dissipation. Usually, this wall-mounted boiler is used for both domestic hot water and heating functions, and will replace the traditional water heater at home. When choosing a wall-mounted boiler, you need to pay attention to the following two points.
①Ensure that the domestic hot water supply is met, the water temperature is constant, and the water flow does not change; because it will be used to provide domestic hot water 365 days a year.
②Meet the heating demand, ensure energy saving, high performance stability, and easy control; the southern heating season generally lasts for about 3 months. That is to say, it can better meet the needs of the above two aspects, and it is a good heating boiler.
2. The choice of radiator, in addition to being good-looking, but also heating up quickly
Many families will choose a radiator system, and in this process, it is necessary to compare radiators Whether it has the three characteristics of watertightness, rapid heating, and generous appearance. Our common radiator materials include iron, aluminum, steel and composite materials. Iron radiators are cheap to manufacture, but have average heat dissipation performance. They are easily oxidized and rough in shape. As early products, they have been gradually eliminated from the market; aluminum The radiator has the best heat dissipation performance, but it is expensive, and it is not resistant to alkali corrosion. The PH value of the injected water is usually greater than 7; the steel radiator has good heat dissipation performance and moderate cost. It is not resistant to acid corrosion, so it is necessary to prevent a large amount of oxygen from entering during the installation process, and it must be maintained with water after the heating season; the radiator made of various materials has high heat dissipation performance and corrosion resistance, but the cost is high , Different materials have different expansion coefficients, and the later heat dissipation effect is inversely proportional to the use time.
3. Heating pipes, whether it leaks or not depends on the connection process
In the heating system, whether it is the supervisor of the radiator or the coil of the floor heating, Pipes are required. The selection criteria for pipes are water-tight, oxygen-proof, and high-temperature resistance. Their common materials are PB, PE-X, aluminum-plastic pipes and hot-melt welded plastic pipes. PB and plastic pipes are both artificially hot-melted. Welding, there are joints that are easy to leak, and plastic pipes have basically been eliminated. Usually, the heating main pipe can choose PE-x material or aluminum-plastic pipe, and the tightening collar connection process is used to prevent water leakage; for floor heating coils, PE-x Both X and PE-RT can be used. The only difference is that the high temperature resistance standards of the two are different. The maximum temperature of the former is 90 degrees, and the latter is high temperature resistance of 70 degrees. The reason for the low radiator.
4.Intelligent temperature control device, energy-saving and comfortable escort
An excellent heating system is indispensable for a temperature control system, with optimized system control The equipment is equal to the heating system with a brain center, which can adjust the indoor temperature in time according to the user’s usage habits, which not only saves energy but also ensures comfort. Now, it can also be combined with the Internet system at home, and remote intelligent control can be realized. Humanization and intelligence bring customers more convenient operation and comfortable life.
