Nowadays, many homes like to change the heating radiator in the home (commonly known as radiator). So, how to choose the right radiator? 1. First of all, be aware of the particularity of the radiator As a building part, heating radiators are different from ordinary furniture in that they are also hot water pressure vessels, and there is a risk of (corrosion) leakage. Therefore, when the owner chooses a radiator in a renovated house, he must have a certain risk awareness and be treated with caution. 2. The radiator should match the heating system The district's water quality characteristics determine the choice of corrosion-resistant copper-aluminum composite radiators or new cast iron radiators. These two radiators have a service life of 25 years and more. Steel radiators are used with caution. Because the air content in the central heating system exceeds the standard, the steel radiator is easy to oxidize and corrode, and the service life is even less than 5 years. Even if the steel radiator is internally corroded, its corrosion resistance is still not as good. Copper-aluminum composite radiator or new cast iron radiator. For independent heating system construction, new cast iron decorative radiators, copper and aluminum, steel radiators are suitable. 3. What qualities does the renovation radiator pay attention to? â— Safety and durability Not easy to corrode and leak. Think about it, snowy winter, sitting in front of the computer to write a blog at night, suddenly, the hot water in the radiator flows down your wooden floor to your feet, how embarrassing it is? The longer the service life, the average to the annual The cost is lower, and you can't just consider the initial purchase price. Cast iron radiators are the safest and most durable, followed by copper-aluminum composite radiators and steel radiators. Consumers of lightweight radiators mainly look at whether the welding is firm and uneven. â— Decorative As a household part, the new and beautiful shape of the radiator is pleasing to the eye and enhance the quality of life. The outer surface of the new radiator is electrostatically sprayed. The surface should be smooth, smooth, uniform in color, free from pitting, orange peel, no flow marks, uniform coating; uniform welds and no weld slag; It is too strong to make the weld smooth and flat, because excessive sanding treatment tends to reduce the strength of the welded part. â— Environmental protection and energy saving Green environmental protection and health is very important! Purchase radiators that have passed the China Environmental Labeling Product Certification (10-ring certification of the Ministry of Environmental Protection), and will not produce or release substances such as toxic and harmful gases during use, which is beneficial to the health of family members, and Meet the requirements of thermal metering and energy saving technology. Based on this, several radiator products that meet the above three key indicators are recommended. Recommendation 1: New inner cavity sandless cast iron radiator Scope of application: Suitable for any heating system and water quality, suitable for all types and grades of building heating. Main features: novel style, smooth and beautiful appearance, equivalent to household appliances, and the quality of traditional cast iron radiators. Energy saving and environmental protection: good ventilation, good for air moisturizing. It is suitable for heat metering and temperature control energy-saving technology requirements. After the end of service life, it has high recycling value and is energy-saving and environmentally friendly. Corrosion resistant, casting life of 50 years, is the longest life radiator, maintenance-free. Recommendation 2: Copper-aluminum composite radiator Scope of application: It is suitable for almost any heating system and water quality, suitable for central heating or independent heating of medium and high-end residential buildings. Main features: safe and reliable, light and beautiful, corrosion-resistant, service life of more than 25 years. Copper-aluminum composite radiator: high-quality and high-grade radiator, the height can reach 1.8m. The steel radiator is straight and tough. The shortcomings are: the closed heating system is required and the pH is alkaline. 4. How many radiators are needed in each room? How many radiators are needed in each room, the calculation is more complicated, and it is designed and calculated by a professional HVAC engineer, but as a consumer, it can be approximated by the following empirical data: (Unit: watts / square meter) Residential insulation 45-70; single-story residential 80-105. The room area multiplied by the heat required per square meter is the heat load of the room, and then the heat dissipation of the heat sink single piece is divided by the actual working condition. (The heat dissipation provided by the manufacturer is generally the standard working condition, so it needs to be converted into actual working conditions, please Consult the property), which is the number of heat sinks required for the room. In the estimation, factors such as different areas, buildings or bungalows, top or bottom, ends or middle, north or south, city or outside, wall insulation should also be considered. After calculating the number of radiators, add an extra 10-20% margin; 5, to have professional installation and after-sales service guarantee. The quality of the radiator installation directly affects the quality and service life of the radiator. Before installation, the original hot water pipe is often modified, which has strong technicality and should be carried out by a professional installation team with certain qualifications to ensure quality. The installation cost is usually recorded separately. Consumers should not rush to change the installation or ask some unqualified installation team to change the installation. Otherwise, the manufacturer is not responsible for compensation in the event of a quality accident. After the installation of the radiator, the pressure detection must be carried out to ensure that the radiator itself and the installation interface are free of leakage. Generally, the pressure of 1.5MPA is suppressed and stabilized for 2 minutes. If there is no leakage, the product and the installation are qualified, and the consumer can Feel free to use it.
