Let's calculate for you, what should be the cost of a 9-element oil plaque with a qualified quality? (Based on the average annual production capacity of 20,000 units), the oil production process can be divided into moulds, nets, paints, plastics, lathes, cast aluminum, stamping and final assembly. The conservative estimate of product cost is about 170 yuan, plus 65 yuan for workers’ wages, freight, taxes, factory net profits, dealer worker wages, dealership freight, taxes, dealer net profit, and mall net profit. Calculate the cost of a 9-piece ordinary oil hydride needs about 200 yuan (excluding manufacturer profits, dealer profits and mall profits). Therefore, if the price of a 9 piece oil jet is too low, it is suicidal. In the face of such prices, consumers should doubt their quality. According to industry sources, the low price of oil may change the internal connection to ordinary wire; shell plate using ordinary steel; does not install overheating protection devices; internal parts shoddy; tablet and tablet connection is not strong; Some even reduce the number of fever tablets. If you buy such an electric heater, it means that you have planted a safety hazard for your home. 
2, brand miscellaneous, more models. In recent years, due to numerous brands debuting in the electric heating market, some unknown products have also joined in, and their addition has also pushed some products with quality problems into the sales market (including those OEM OEM products). Most of these products are based on brand-name products, but only on the faceplate and packaging, to confuse consumers. When consumers purchase electric heating, it is best to look for well-known brands or reasonably priced products. 
3. After-sales service. In order to occupy the market, various brands have launched many attractive after-sales service commitments. Some unknown companies' after-sales services are even more surprising. As we all know, the well-known brands of oil tings after-sales service is generally 3 years. We have to express doubts about those commitments over 3 years. How much money can they earn? The price itself is low, coupled with an overly concessional service commitment. Are they losing money to sell? You know, businesses do not make a loss of business. In the past two years, it has been common for consumers who have bought such products to look for maintenance points with unknown electric heaters. Not to mention home maintenance, the manufacturers are gone. Consumers who are deceived can only go to other brand-name electric heating repair points.
4, what to buy products to see. How to choose electric heating? We have 6 selection indicators: 1) What kind of connection is the internal connection? The best connection on the market today is aviation wire. 2) How many millimeters is the oil jacket? Normal is 0.6 mm. 3) Whether the connection between the tablet and the tablet is firm. 4) Is there any overheat protection device? 5) How many pieces of fever are in the end? 6) Use double-explosion-proof flame retardant. 
If you can take care of the above conditions when selecting products, then you absolutely choose a safe and reliable electric heater.
