I just bought Weineng's wall-hung boiler. Because it is the first time to use gas, I want to ask my friends how to save money when using it. I am a miser. Wow, haha ~ ~ ~

Natural gas wall-hung boiler is a little more expensive than central heating, but reasonable use can also achieve the purpose of saving. Hey hey, you can't decide whether to choose Weineng or wiesmann. Actually, these two brands are both good. Technically, I personally prefer Weineng. The condensation technology is well done, and the thermal efficiency is as high as 109%. This industry is really one of the best. Moreover, the performance of Weineng is more stable and professional than that of viessmann. It is equipped with a stepping valve, and the temperature can be accurately adjusted. How much gas you want to use, how to use it yourself.
