What is the price of commercial gas wall-hung boiler?

Commercial wall-hung boilers are generally expensive, mostly tens of thousands or more. Last year, our residential property bought a commercial wall-hung boiler in Dong Qing, with NFB-98HC heating system, and it felt good. The response of residents is much more enthusiastic than in previous years, even the corridors are warm and boiler burning is omitted. Personally, I think it's quite good. You can learn about it, I hope it will be useful to you.
