Assuming that the 10 ton/hour gas hot water boiler costs 500,000 RMB when purchased, the annual depreciation of the boiler is: 500000-(500000*5%)/10 = 497500 RMB.
Assuming the residual rate is set at 5%, and it is expected to use 10 years, then the annual depreciation rate of 10 tons/hour industrial gas boiler = (1-5%)/10*100% = 9.5%.
The monthly depreciation rate of the 10 ton/hour gas hot water boiler is 9.5% ÷ 12 = 0.79%.
The monthly depreciation of the 10 ton / hour gas hot water boiler = 0.79% * 500000 = 3950 RMB= 571.5US dollars.




We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
