What is Biomass Fuel?
Your biomass boiler will burn most kinds of bio-matter such as grains, wood chips, olive kernels, saw dust, wood logs, cocoa pellets and wood pellets.
Which is the Most Efficient Fuel?
The table below clearly shows that bagged wood pellets are indeed the most efficient fuels when it comes to kWh per kilo of fuel, but they are also the most popular fuel type for biomass boilers because they are the easiest and cleanest fuel to work with.
|Cost/Ton||kWh/Ton||pence/kWh||kW value at meter|
|Wood Pellet (bagged)||£290||4800||6.04||6.13|
|Wood Pellet (10%)||£250||4800||5.21||5.39|
|Wood Chip (20%)||£150||4100||3.66||4.30|
|Wood Chip (30%)||£120||3500||3.43||4.03|
|Wood Chip (40%)||£90||2900||3.10||3.65|
|Wood Chip (50%)||£70||2300||3.04||3.58|
Wood pellets may be the most popular fuel source to use with biomass boilers, however if you want to get the most for your money and don't mind a little extra hard work in taking care of your biomass boiler then wood chips deliver a much better return as it is far cheaper to produce than pellets. Also if you have access to your of wood supply, you could even chip the wood yourself and save more money. BUT, This does come with a slight catch, wood chip boilers are more expensive to install than pellet only machines, these are most popular with farms and industrial plants.How does the running cost of biomass compare to other conventional boilers?
