We're considering a biomass boiler for our guesthouse (1820 vintage with corresponding energy issues). The opportunity to reduce gas usage and the economics of the RHI scheme in the UK (a sort-of feed-in tariff for logs) would seem to make this a no-brainer choice.
However, word-of-mouth comments question whether the source of wood pellets for the boiler is itself very sustainable.
Does anyone have any reliable references or pointers where I can learn more about this?
Edit: have found this one from Ethical Consumer. http://www.ethicalconsumer.org/buyersguides/energy/biomassboilers.aspx
PS. We have considered wood chip, and log, variants of biomass boilers which avoids the pellet manufacturing process and would offer better chances of a geographical local source. There are various logistical issues with these in our particular circumstances.
