Technical Information

We have developed our heaters by listening to our cutsomers requirements. We are able to burn difficult fuels such as woodchip and sawdust, in an auto feed unit. We can even factory-fit all the system inside an ISO shipping container to minimise work and allow for seasonal relocation.

Dragon have two ranges of boiler

11 x Single pass models, for low cost start up and difficult to burn fuels

13 x Double pass models including 11 RHI approved boilers for batch burning and high efficiency

All boilers are built using boiler plate and come with a 3 year guarantee
