We offer ENplus A1 quality wood pellets. They are produced by a number of manufacturers. That may include the manufacturer you are looking for, but you are fooling yourself if you think specifying a particular brand of wood pellets is a good idea.
What will you do when wood pellets from that source aren't available? Any manufacturer can have an interruption to their production, such as a fire at the plant. All manufacturers will experience variations in the characteristics of their wood pellets, because wood is a variable feedstock, and other factors in the production will also vary from time to time. Manufacturers can go out of business, leaving you high and dry if you think only their wood pellets will do.
The point of the ENplus wood pellet accreditation scheme is to provide procedures and specifications so that boiler manufacturers, installers and customers can know that accredited pellets will exceed a specified standard that they can design for. The boilers are not tested and certified for use with a particular brand of wood pellet. They are tested and certified for use with a generic standard of wood pellet (e.g. ENplus A1), so that multiple sources of wood pellets can be used with the boiler. If boilers were manufactured to suit a particular brand of wood pellets, there would be a lot of small, local manufacturers of specialist pellet boilers, or in fact, no manufacturers of pellet boilers, because the technology would not be credible or economically viable.
