Is the water in the radiator of the wall-hung boiler changed once a year?

The radiator of the wall-hung boiler does not change water once a year. Wall-hung boilers have been used for a long time, and it is easy to accumulate scale, which leads to the decline of heating effect. Therefore, it is necessary to change the water of the wall-hung boiler regularly, but the water of the wall-hung boiler does not need to be changed every year, and it is generally enough to change the water once every two years. If you use it for the first time, you should change the water after one year, and then change the water after two years.

What are the skills of choosing radiator for wall-hung boiler?

1, low carbon steel, which is a substitute for cast iron in the past and is also widely used in the market at present. The advantages of this radiator are relatively high price and mature technology. At the same time, you can choose the color of the radiator of the wall-hung boiler. The disadvantage is that the heating speed is slow and it is easy to be corroded.

2. The copper-aluminum composite radiator adopts aluminum to conduct heat, and the copper tube conducts water for anticorrosion. The advantages are that aluminum can be used for heat conduction to quickly raise and lower the temperature, and copper can be used to reduce the corrosion of water on aluminum, which is beautiful in appearance and easy to take care of; The disadvantage is that the coefficient of thermal expansion of copper and aluminum is different, and it is easy to produce vacuum between copper and aluminum when heating and cooling for a long time, and the connection is not firm. In addition, adding copper will increase the cost.

3. Die-casting aluminum is a new type of radiator that emerged two years ago. The advantages are integral casting, few welding spots, long service life, fast heat conduction speed of all-aluminum manufacturing and beautiful appearance; The disadvantage is that aluminum is very easy to be corroded, and many pieces on the market are not really completely cast, resulting in more pieces that can be added at will, more welding points and easy leakage.

4. Steel plates are mostly imported from abroad, and the process is complicated. The advantages are good heat dissipation effect and beautiful appearance. The disadvantage is that the price is more expensive, and because of the fine production, it is not suitable for areas with poor water quality.

How to save solar terms for wall-hung boilers?

1. Wall-hung boiler solar energy-saving method-Turn off or turn down the radiator valve in the unoccupied room: If you have a large housing area, many rooms and a small population, you can completely turn off or turn down the radiator valve in the unoccupied room or the room with low frequency of use, which is equivalent to reducing the heating area, saving energy, speeding up the heating in the normally used space and reducing the gas consumption.

2, wall-hung boiler solar terms method-it is not appropriate to turn off the wall-hung boiler when there is no one at home during the day, just adjust the temperature to a very low level: many office workers are used to turning off the boiler when there is no one at home, and then put the boiler in a high-end place after work. It is unscientific. Because this means that starting from scratch, due to the large temperature difference between the room temperature and the boiler set temperature, the boiler needs time to ignite, which not only saves energy, but also wastes gas, increases the time for residents to catch cold, and there is a danger that the boiler or radiator will be frozen.

3, wall-hung boiler solar terms method-wall-hung boiler itself is the key to solar terms, a gas-saving wall-hung boiler can save you a lot of follow-up costs. First of all, national energy efficiency labeling is necessary. Of course, the higher the energy efficiency, the better, but now the national standard is level 2. Secondly, the original imports are more exhaust gas. Because the gas mixing ratio in each region is different, and the economic conditions of residents are also different. Therefore, many foreign brands have been localized after entering China. Voorburg, Germany improved the German design to adapt to the national conditions of China, and changed the small fire exhaust and high flue temperature commonly used in European wall-hung boilers into multi-burners, which reduced the flue temperature and greatly reduced energy consumption.

4. Water-saving method of wall-hung boiler-If you have been on a business trip for a long time or have never lived, let the water in the boiler and radiator go out: I suggest you ask a professional to clean the water in the boiler and radiator, so that you can not only use gas, but also worry about the boiler or radiator being frozen.

5. Wall-hung boiler thermostat-Use wall-hung boiler thermostat to control the room temperature and divide the time, so as to realize heating according to customer's needs and avoid gas waste.
