Due to excess air and the burning season, many users pre-burn excessively when decorating gas wall-hung boilers. However, many users feel confused when choosing wall-hung boilers. The market offers wall-hung boilers with European technology, and also condensing boilers from some domestic manufacturers that claim to recover waste heat. So, for users, how to choose a condensing boiler from top to bottom? The principle of condensing boilers involves the outlet and secondary heat exchange device of traditional wall-hung boilers, but the combustion method still uses traditional gas combustion, which can easily lead to waste due to insufficient gas combustion, or generate excessive nitrogen oxides due to excess gas, causing losses in some wall-hung boilers. Therefore, the main condenser is a semi-condensing wall-hung boiler, not the entire gas wall-hung boiler. NOx wall-hung boilers, suitable for different applications, have their combustion chambers made of stainless steel or silicon materials. The heat exchanger is a highly corrosion-resistant stainless steel material with good acid corrosion resistance. Therefore, its design life is generally more than 15 years, and choosing a condensing wall-hung boiler that is more than semi-condensing will far exceed the service life of a semi-condensing wall-hung boiler. The core issue with this suitable condensing wall-hung boiler is that the wider the power adjustment range, the more accurate the operating temperature, and the higher its suitability. Due to its wider power adjustment range, it avoids frequent boiler startups and shutdowns, allows for low-temperature operation, and enables constant temperature power adjustment from a human health perspective. When selecting, consider features like aluminum alloy regulating furnaces, condensing focusing furnaces, and heavy condensing wall-hung boilers, along with their suitable price-performance ratio. It's advisable to prioritize brands. Various alloys are used, including aluminum alloy and stainless steel alloy.
