You can read more about the benefits of different fuel types, chip and pellets, and which might be best for your project in this blog article by Rural Energy, one of our installation partners: Wood Chip vs. Wood Pellets - The benefits of different biomass wood fuel.
Research your local fuel supplier
The Biomass Suppliers List (BSL) is a fantastic source of wood fuel providers that you can search through using just a postcode. Businesses and their products on this list meet certain standards, as set out by the UK Timber Standard for Heat and Electricity, which ensure that the wood supplied is in line with RHI-qualifying criteria. Whether you intend to claim the RHI or not, obtaining your fuel from a reputable and approved supplier is recommended to ensure a constant supply of high quality wood.
Keeping your system running efficiently
Using the best quality wood fuel for your biomass heating system is the most efficient and cost-effective way of fuelling your heating system, whilst minimising possible issues that could arise from using lower-quality fuels.
Most of our Herz boilers offer the flexibility of being able to run on either wood chip or wood pellet fuel. To change between fuel types, a re-commissioning visit is required to align the boiler software with the new fuel features and requirements to ensure a smooth transition.
We also offer Industrial solutions for other types of wood fuel, such as waste, treated and non-woody options, alongside the Domestic and Commercial boiler options.
