• Clean heat transfer surfaces ensure the most efficient heat transfer. Natural gas burns clean, so fire-side surfaces tend not to foul in gas-fired boilers, but scale deposits on the water side act as insulation, reducing boiler efficiency by as much as 10 percent. Excess scaling can lead to boiler tube blistering and ultimately to tube failure.
