Biomass Boiler Containers
Custom Built Biomass Boiler Containers
Containers Direct specialise in converting standard steel shipping containers into custom built biomass boiler containers suitable for housing biomass boilers, equipment and fuel stores.
Shipping containers are fast becoming the popular choice as the starting point for producing self-contained biomass boiler houses. Containers for biomass boilers are often required by schools and other municipal buildings where budgets and planning regulations do not allow for a new structure to be erected.To respond to this need Containers Direct have started taking contracts to convert the standard steel shipping container into a custom built structure suitable for housing the biomass boiler.
Choose from new shipping containers or used shipping containers, or bespoke new builds. We have a full range of shipping container sizes to choose from, so whether you need a small biomass boiler in a 10ft container, a standard 20ft container or a 40ft container we can provide it.What is a biomass boiler?

Bio mass fuel can be any renewable source, but most commonly wood chip or wood pellets are used. The fuel store is directly connected to the boiler room via apetures in the container walls, and the pellets are automatically fed through by means of a rotating feeder pipe connecting the two. The pellets are burnt in the pellet boiler, leaving only ash to be disposed of. This process results in far lower CO2 emissions than fossil fuels, and is completely sustainable.
Why choose a biomass boiler?
Along with reduced CO2 emissions and being ecologically sustainable, the government's Renewable Heating Incentive Scheme (RHI), means the biomass converter can both pay for itself AND generate income!
Non-Domestic
This scheme allows businesses, public sector and non commercial organisations that invest in renewable energy to earn quarterly payments throughout a 20 year period. Funded by the government and regulated by Ofgem, you can apply for payments online via Ofgem's website.
Domestic
This recent development means that domestic dwellings can now receive quarterly payments over a period of 7 years, for the amount of energy their system produces.
