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.
