How to choose a condensing wall-mounted boiler?

Due to excess air and the burning season, many users pre-burn excess when decorating gas wall-mounted boilers. However, many users feel confused when choosing a hanging boiler. There are wall-mounted boilers with European technology on the market, as well as some domestic manufacturers promoting condensing boilers that can also recover waste heat. So, how should users choose between condensing boilers? The principle of a condensing boiler is similar to that of a traditional wall-mounted boiler, with an outlet and a secondary heat exchange device, but the combustion method still uses traditional gas combustion. Due to insufficient gas combustion, it is easy to waste gas or produce excess nitrogen oxides, leading to losses in some wall-mounted boilers. Therefore, the main type of condensing boiler is a semi-condensing boiler, rather than a fully condensing gas wall-mounted boiler. The appropriate type varies, with combustion chambers made of stainless steel or silicon materials. The heat exchanger is made of a highly corrosion-resistant stainless steel material, which has good acid corrosion resistance. As a result, its design life is generally over 15 years, and the lifespan of a semi-condensing wall-mounted boiler far exceeds that of a fully condensing wall-mounted boiler. The core issue with suitable condensing wall-mounted boilers is that the larger the power adjustment range, the more accurate the operating temperature, and the higher the suitability. A larger power adjustment range allows for wider operation, avoiding frequent boiler starts and stops, and can meet low-temperature operation needs. The power adjustment maintains a constant temperature from a health perspective, adjusting the aluminum angle, and so on. When considering a condensing wall-mounted boiler, it is important to look at the price, but more importantly, to consider the brand. Using aluminum alloy, the condensing wall-mounted boiler should be made of high-quality materials. The price should be reasonable, and the focus should be on the brand and the materials used, such as stainless steel and aluminum alloys.
