#### Boiler Efficiency and Types | buderusboilersguide

For commercial use you can choose one of the floor standing boilers either condensing or high efficiency with outputs starting at 78 kW and finishing at around 1200 kW. For industrial usage you should go with one of the CHP models, but you need take into consideration that these are big boilers that require a separate storage place, not only due the size but also noise.

More#### Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses. Table 3.2.
