Gas Fired Hot Water Boiler

Heat output: 35-3500 KW
Natural gas, LPG, propane or biogas
92-92.5% efficiency


Product Description:

The gas fired hot water boiler is a kind of hot water boiler, which can satisfy the demand of supplying hot water and heating separately.  This gas fired hot water boiler uses gas, such as natural gas, liquefied petroleum gas, biogas, etc. as fuel, and heat the water through a burner to achieve heating and hot water supply.
