Bio-mass boilers do of course need bio-mass therefore the availability of an energy source will have considerable effect on the suitability of a bio-mass boiler as a source of hot water and space heating.
If there is a good and consistent source of bio-mass locally, or if the possibility exists of growing your own bio-mass will have a great deal of impact upon how suitable this solution may be for you.
As ever a bio-mass boiler would usually be seen as one piece in the larger renewable energy jigsaw. EcoSaveit will look at the wider picture and will be happy to help you plan a total renewables strategy.
