Burning biomass does not consume fossil fuels, but it does release CO2 into the environment (66% more than burning gas, 21% more than burning oil for the same quantity of heat). Heat from biomass boilers is nevertheless considered to be renewable because it does not come from burning fossil fuels.
You need to consider the element of embedded carbon in the transport costs – especially if the biomass fuel is imported. Consider the effect on air quality.
The sizing of the biomass boilers, the sizing of thermal stores and the controls are important in achieving efficient heating performance.
Biomass boilers are not able to provide any cooling.
Biomass boilers require on-going management and maintenance as well as space for installation, fuel delivery and fuel storage. They take time to heat up and cool down, but can be made to work well if there is a sustainable supply of cheap local biofuel.
Biomass boilers emit NO2 which exacerbates problems of air pollution. Air quality is an increasing concern in cities like London where nearly all boroughs exceed EU limits for acceptable concentrations of NO2.
