What is Biomass?

 

Biomass is an alternative solid fuel to the conventional fossil fuels. Various types of biomass fuels are in use such as trees, animal by products and general waste products to produce energy. The most common for homes and commercial heating applications are wood based fuels such as woodchips and wood pellets. These wood pellets are made from low grade by products of the wood industry such as dry sawdust and shavings, produced in large quantities.

 

How does it work?

 

There are two main ways of using these wood pellets to heat your home or business.

A standalone stove to heat individual rooms (this option can also be fitted with a back boiler to provide water heating as well).
A boiler, burning pellets, logs or chips connected to your existing central heating and hot water system. Pellets can either be manually fed into the system or there are automatic fuel feeders, which refill them at regular intervals from fuel storage units called hoppers.

Appliances can achieve efficiencies of more than 80% and produce very little pollution. The burning of this wood is also a great way of disposing of the waste that might otherwise be sent to a landfill site.

 

What are the benefits?

 

Reduce your energy bills by 40%

There is a potential when replacing a fossil fuel boiler to biomass to save up to 40% on your fuel bills. The scale of the saving will depend on the fossil fuel, which you are replacing, and the cost of the biomass used.

Reduce your impact on the environment

 

Pellets are stored solar energy, and when burned are carbon neutral. Only the CO2 absorbed by the photosynthesis during the growth of the tree is being released. According the Energy Saving Trust there is potential to save up to 9.6 tonnes of CO2 per year when replacing a solid (coal) fired system.

 

Reduce your dependency on fossil fuel imports

Energy supplies are becoming a growing concern. Price rises are becoming ever more likely due to the instabilities in the oil and gas producing countries. Any price change in wood is going to be less extreme, therefore a more environmental and financial solution.

Improved efficiency and lower maintenance costs

Conventional fossil fuel boilers turn themselves on and off, wood pellet boilers alter their firing rate to the exact energy requirements in your home or business. There is a reduction in electricity consumption, an increase efficiency grade and a longer life of the appliance, which all means lower energy bills and operating costs for you.

Improved Energy performance ratings for buildings

 

By installing a biomass boiler in either a new build or refurbished property you will help improve both your property or buildings overall environmental energy performance and help it achieve a reduction in CO2 emissions. For more information about Sol2o's EPC service click here.

Frequently Asked Questions

 

Will I need to change my existing heating distribution system?

Biomass boilers can be used with existing radiators and underfloor heating, or as part of a warm air heating system. If you currently have electric storage heaters and want to install a biomass boiler, then a new heating distribution system will need to be installed. Sol2o will be able to advise on the suitably of your current system, and design and install and changes that are required to make the system more efficient.

 

What controls are available?

Boilers and stoves are available with thermostatic temperature controls, programmers and timers as with modern oil/gas boilers. Stoves generally use fans to give an even heating temperature.

Will my system give off smoke?

A well-installed system using high quality dry fuel will usually burn without any visible smoke. You will need a vent, which are specifically designed for wood fuel appliances with sufficient air movement for proper operation of the stove/boiler.

What maintenance is needed?

Boilers produce typically less than 1% ash, which can be used as a fertiliser in your garden. Some appliances, particularly boilers, have self-cleaning systems built in, or compacting ash-collection pans that typically need emptying once a month. They will however need to be swept out regularly.

What is typical lifetime of boiler/stove?

Biomass appliances will last around 20 years if kept in good repair throughout their life.

How much will fuel cost a year?

Fuel costs generally depend on the choice of fuel, distance from your supplier and whether you can buy in large quantities.

What if I run out of fuel?

Some pellet boilers have adjustable settings that will allow them to burn other types of fuel. Can also have gas/oil back up supply or integrated solar thermal panels.

Do you have enough space?

You will need a large dry area close to the boiler to store your wood. Ideally this should be close to where the wood is delivered to your home or building to minimise the distance you have to carry it.

Where will I get my fuel?

Fuels used typically with biomass heating systems tend to have diverse and localised fuel supply chains. UK sourced biomass can offer local business opportunities and support the rural community.

 

* Try to keep your fuel supply as local as possible to reduce CO2 emissions from delivery of fuel.
