Are condensing boilers all advantages and no disadvantages?

　　Low-nitrogen condensing boilers enjoy a high reputation in more and more condensing boiler equipment due to their advantages of highly intelligent control, emission of toxic gases below national standards, and effective condensation heat transfer. Customers ask if there are any disadvantages to condensing boilers. From the current application point of view, the possible minor defects are cross-traditional boilers, and higher prices. However, from the perspective of sustainable development,Condensing boilerIn fact, a penny's worth of goods is produced, and the money invested at the beginning will be saved in the subsequent heating process. There are also BOT, MEC and other investment cooperation models, and merchants can enjoy comfortable heating services brought by condensing boilers without paying a penny.

　　Then customers will ask whether the quality of condensing boilers is guaranteed. At present, there are also factories manufacturing condensing boilers in China, but there is no guarantee in this aspect, and most durable condensing boilers are still imported. Condensing boilers are imported from original European machines, and the casting materials are now proven to be fast heat dissipation, strong corrosion resistance, and light alloys, which can be used for 40 years. In addition, during the warranty period, they can be quickly replaced in local sources, and a very fast after-sale service system can immediately solve heating problems, so there is no need to worry about the quality of the boiler. With the continuous improvement of condensing equipment technology, condensing boiler equipment manufacturers are also striving to improve existing production processes to bring more benefits to condensing equipment, and it is believed that condensing boilers will perform better in the future.

　　Application of Condensing Boilers

　　The energy efficiency standard of a fully mixed condensing gas boiler is Grade 1 (national standard stipulates Grade 1 energy efficiency thermal efficiency) 96%, inCondensing boilerIn actual use, the efficiency can reach 96% ~ 107.7%, and some products can reach 108.9%. Under what circumstances can the thermal efficiency be maximized.

　　(1) When operating at 50 ~ 30, the thermal efficiency is 108.9% ~ 103%.

　　(2) When operating at 80 ~ 60, the thermal efficiency is 98.6% ~ 96%.

　　As you can see, the entire premixed condensing gas boiler has higher thermal efficiency at low temperatures. For traditional gas boilers, the thermal efficiency of around 91% is far lower than the minimum thermal efficiency of 96% for condensing boilers. In the case of large-area heating, it is conceivable how much energy condensing boilers can save.

　　Nowadays, heating generally uses two methods: one is warm period, and the other is global warming.

　　For heater systems, high-temperature operating conditions such as 80 water supply and 60 return water are generally used, usingCondensing boilerThe thermal efficiency is between 98.6% and 96%, which still belongs to Grade 1 energy efficiency. The existing boiler only has a thermal efficiency of 91%. Obviously, the thermal efficiency of using a condensing boiler is higher, and the energy efficiency is higher. For global warming systems, we generally use low-temperature operating conditions, such as 55 water supply and 45 return water. Then, the thermal efficiency of using a condensing boiler needs to be higher than that when using an ordinary boiler.
