Why should you use ISO 17225-5- *Graded firewood***?

Firewood is typically round or split log cut too short lengths and used for producing energy in household wood-burning appliances such as stoves, fireplaces, and central heating systems.

The objective of ISO 17225-5 is to provide the user with unambiguous and clear classification principles for solid biofuels; to serve as a tool to enable efficient trading of solid biofuels; to enable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers. ISO 17225-5 facilitates authority permission procedures and reporting.

ISO 17225-5 supports the use of graded firewood for residential, small commercial, and public buildings which requires classified firewood quality.

The residential, small commercial and public building applications require high-quality fuel for the following reasons:

Small-scale equipment does not usually have advanced controls and flue gas cleaning
Appliances are not generally managed by professional heating engineers
Appliances are often located in residential and populated districts

Overall, ISO 17225-5 is helpful as it assists the user with the fuel specifications and classes of graded firewood. ISO 17225-5 provides facilities that utilize solid biofuel-burning appliances or equipment that have similar fuel requirements as residential appliances which can help you in your business.
