Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust. Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the exclusive radiation and convection losses. Fuel to Fluid Efficiency - indicates the overall efficiency of the
Nov 23 2016 · Your chosen boiler (for example the Greenstar FS 30CDi or FS 42CDi) can be fitted or piped just like a regular boiler but instead of a concentric flue going through the wall with a 100mm duct drawing in and a 60mm duct expelling the fumes a concentric flue goes from the
