FAQ
What is biomass?
Biomass is typically a fuel that is made from organic materials, which might include forest debris or manure from animals.
This is a much more sustainable answer to fuel needs, as it will very likely never run out and can be produced again and again.
Biomass can create carbon-neutral energy out of materials that would have otherwise been thrown away, recycling waste and turning it into energy.
Many homes and companies are turning to biomass to become more sustainable and save money.
What can be used for biomass fuels?
- ✔ Wood chips, pellets and logs
- ✔ Crops
- ✔ Debris from forests
- ✔ Manure from animals
- ✔ Waste residues
What is a biomass boiler?
A biomass boiler uses the organic materials to generate energy, typically used for heating either your home or your water supply.
Sometimes, you might have a boiler but also other equipment or specialised rooms to hold all of your fuel, such as an eco-room for pellets or wood chips.
You might either purchase bags of this organic matter from a local provider. For larger businesses, they might have weekly or monthly shipments of these materials.
How do biomass boilers work?
- Your biological materials will be fed into the combustion chamber.
- Then, the combustion chamber will ignite these materials.
- The hot gas and air will travel through a flue.
- It will end up going through a heat exchanger.
- This transfers the heat to the water used in your central heating system.
What are the benefits of biomass?
Using biomass materials for your home’s energy and water heating is far more eco-friendly and less expensive. Furthermore, because it is sustainable, you won’t have to worry about using fossil fuels.
Is biomass less expensive than gas?
Although the cost of wood pellets are close to the price of gas, you should also consider that biomass will be a far more attractive option in the future rather than using traditional fossil fuels.
The cost of fuel, for example, will likely rise exponentially as fossil fuels deplete, whereas using wood pellets or chips should maintain a level cost. This is because wooden chips or manure can be replenished continuously.
How much do biomass boilers cost?
A domestic biomass boiler might cost as much as £10,000, with a further £2,000 to install, which makes biomass boilers significantly more expensive than gas boilers, which are traditionally only around £500.
However, you could end up saving a significant amount of money in the future, especially as more and more homes and businesses move towards renewable energy.
How long will biomass boilers last?
If you have your biomass boiler serviced every year, it should last for at least 20 years, which is more than a gas boiler (lasting for only around 10 years).
Is a biomass boiler right for me?
This depends on many different factors, including:
- Your budget
- Whether you want to be eco-conscious
- If your home or business has the right room
- If you have access to biomass fuel
- If you can find a biomass boiler to match your needs
Do I need planning permission?
Generally speaking, you won’t need to have planning permission to have a biomass boiler, but this depends on certain factors, such as the size of your building, the flue height, and your roof.
The flue attached to your biomass boiler can’t be 1 meter taller than your roof height.
Conclusion
A biomass boiler could be an excellent fit for your home or business if you want to become more environmentally friendly and save some funds in the long run.
