Biomass is a renewable energy technology and is classified as Carbon neutral. As trees grow they absorb carbon from the atmosphere (and produce Oxygen). This carbon is stored in the tree. If this tree was to be left to decompose, this captured Carbon would be released back to the atmosphere over a few years. Burning that material will also release the carbon but will make use of the energy in the process.
A biomass heating boiler is a boiler designed to burn solid fuels classed as biomass. Such boilers can be supplied to burn every form of biomass from woodchips, wood pellets or logs to waste agricultural materials such as straw and grain husks, olive kernels, rice and the dust from any of these including sawdust. Boilers need to be designed to burn specific materials, with any given boiler able to burn a limited range of biomass.
Biomass systems come in a range of sizes and typically burn wood pellets, wood chips or logs. They provide space heating and hot water to domestic, commercial and industrial users. Modern, efficient biomass heating systems are computer controlled, easy to maintain and operate and are common throughout Europe and Scandinavia.
A biomass boiler is an ideal replacement for an existing boiler powered by gas, oil or LPG. They operate in a similar way to traditional boiler systems, are easy to clean and maintain, are reliable, they improve efficiencies, significantly reduce costs and are better for the environment. The only main difference between a biomass boiler and a conventional boiler system, is the delivery of fuel.
There are three main types of Biomass Boilers: Pellet Boilers, Wood Chip Boilers, and Log Burning Boilers.
The choice of fuel and the supply of that fuel are dependent on the individual customer’s situation. A lot of Devon Power’s agricultural customers prefer to use Wood Chip, as they are generally available on their land through the sustainable management of woodlands, and from also making use of any fallen trees on the property. Having this source of fuel on their property removes any purchase and transport costs and makes the return on the investment even higher.
On 10 March 2011, the Government announced details of the Renewable Heat Incentive policy to revolutionize the way heat is generated and used. This is the first financial support scheme for renewable heat of its kind in the world.
The RHI scheme has been set up with size bands for these renewable developments, this gives higher tariffs for smaller projects which enables all renewable energy projects to have similar returns on the investment. The scheme guarantees regular payments for 20 years and the income gained is determined by the amount of renewable heat generated by a biomass boiler. The tariff rate is raised in line with inflation.
There are two phases to the introduction of the RHI:

This table illustrates the annual cost to produce heat for 15% of the year producing 131400kWh. The values are generated by multiplying this figure by the current fuel prices and Renewable Heat Incentive payment values.
|Wood Chip||2.9p (per kWh)|
Using biomass heating for fuel will significantly reduce your heating costs.
The table below illustrates how much you will earn, under the Commercail RHI scheme after 20 years:
|RHI Payback||Output (kW)||Annual Load (h)||Annual Load (kWh)||Tariff||Total|
|Projected RHI Income in 20 yrs||£645,916.17|
