    2 天前 · Gas-fired boilers are designed to operate on either propane or natural gas. Some gas-fired boilers can be switched over to one or the other with some modifications to account for the different characteristics of the fuels. Oil-fired boilers used gasoline or other petroleum-based fluids as the fuel source. Thermic fluid heaters (described above) use these fluids as the heat transfer medium.
