What is biomass?

Biomass is typically a fuel that is made from organic materials, which might include things like 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 it can be produced again and again.

Biomass can create carbon-neutral energy out of materials that would have otherwise have been thrown away, making it not only eco-conscious in terms of the lower emissions but also it recycles waste and turns it into energy.

Many homes and companies alike are turning to biomass for these reasons, both to become greener as well as save money.

What can be used for biomass fuels?

✔ Wood chips, pellets and logs

✔ Crops

✔ Debris from forests

✔ Manure from animals

✔ Some 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 possibly your water supply as well.

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, or for a more significant business you might have weekly or monthly shipments.

How do biomass boilers work?

  1. Your biological materials will be fed into the combustion chamber
  2. Then, the combustion chamber will ignite these materials
  3. The hot gas and air will travel through a flue
  4. It will end up going through a heat exchanger
  5. This transfers the heat to the water used in your central heating system

What are the benefits of biomass?

There are many benefits to using biomass materials for your home’s energy and water heating, such as the fact that it is far more eco-friendly, it will likely be less expensive, and because it is sustainable, you won’t have to worry about depleting fossil fuels.

Is biomass less expensive than gas?

Although the cost of wood pellets are close to the price of gas to fuel your home, you should also consider that moving forward using biomass will be a far more attractive option to 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 every day, continuously.

How much do biomass boilers cost?

A domestic biomass boiler might cost as much as £7,000, with a further £2,000 to install, which makes biomass boilers significantly more expensive than gas boilers which are traditionally only around £2,000.

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?

While you should have any boiler serviced every year, a biomass boiler should last for at least 20 years, which is more than a gas boiler which might only last around ten years.

Is a biomass boiler right for me?

So, is a biomass boiler the right decision for you?

This depends on many different factors, including the following:

  • Your budget
  • Whether you want to be eco-conscious
  • If your home or business has the right room
  • Should 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 as well as your roof.

The flue attached to your biomass boiler can’t exceed 1 meter taller than your roof height.


In conclusion, a biomass boiler could be an excellent fit for you, your home or your business if you want to become more environmentally friendly and save some funds in the long run.
