Biofuel boilers have emerged as a promising solution in the quest for sustainable energy sources. But what exactly are biogas boilers, and why are they gaining traction in 2024?
Biofuel boilers are heating systems that utilise organic materials, such as wood pellets, chips, or logs, to generate heat and hot water. Unlike traditional fossil fuel boilers, which rely on finite resources like oil or gas, biomgas boilers harness renewable energy from biomass sources. In 2024, biomass boilers have become increasingly relevant with growing concerns about climate change and the need for cleaner energy alternatives.
In this competent guide, we will cover various topics, such as the best biomass boiler and its advantages and disadvantages and biomass boiler cost.
What is a Biomass Boiler?
Boilers that use wood can heat multiple rooms, just like regular gas boilers.
Biogas Boilers provide a clean, renewable energy source many homeowners are switching to, thanks to the continuing energy crisis and global warming concerns.
Biomass Heating uses sustainable biomass fuel derived from animal waste, plants, or wood to generate heat for your property or buildings.
With an efficiency of 80%-91%, biomass boilers are considered one of the renewable heat options. They offer more efficient features than conventional fossil fuel boilers, making them ideal for customers looking for renewable and efficient heating.
However, unlike gas boilers, biofuel boilers do not require fossil fuels to produce heat. Instead, they burn sawdust or wood chips, which are made from sawdust, plants, or other sustainably sourced organic matter.
The boiler will burn these wood, chips, or pellets to heat a room – a backhoe can also be installed to heat water.
You can get a biomass boiler that you have to fill manually, or you can get one with an automatic feed hopper, which will periodically feed fresh wood into the machine.
Biomass Heating: How it Works
Biogas Boilers are the most common form of Biomass Heating that works the same way as traditional boilers, but instead, they burn sustainable fuel made from organic materials to produce heat.
First, organic matter (such as wood chips or chips) enters the fuel tank. Normally, an auger and agitator will transfer wood fuel from the shop to the boiler combustion chamber smoothly, but this will depend on whether the boiler is a self-fed model. If the biomass boiler is hand-fed, then any auger of the Windegar Firewin range will not need the biomass fuel, which will need to be supplemented with alcohol.
Second, whenever there is a need for heat, a process called gasification begins. The wood fuel in the combustion chamber then sets it on fire on its own, and the fuel starts to evaporate.
Next, secondary combustion happens when air is added to the chamber and mixed with the gases that are being made. This air is then burned off, creating temperatures of up to 1,200˚C.
Lastly, the Biomass Boiler will have a heat exchanger that will heat the water inside by passing it through the hot gases. After leaving the boiler, the hot water will be sent to different parts of the house to heat them.
Before you invest in a biomass boiler, you should know that most of them need a buffer tank. However, some, like the Windegar Biowin line, doesn’t need a tank.
Homeowners or people who live with a homeowner at the same address who does are turning to biomass boilers as an affordable and eco-friendly way to heat their homes and make hot water. Like any other heating system, biofuel boilers have pros and cons that need to be thought about before a choice is made. Here are some of the main advantages and disadvantages of biogas boilers:
Biomass Boilers Pros
- You may already know that biomass is considered an environmentally friendly energy source. Mass biomass is a natural source of energy that is easy to get by planting or changing trees or plants. On the other hand, coal takes over a thousand years to grow back.
- Biomass can be thought as a carbon-neutral energy source, since plants take in the carbon dioxide that is released when biomass is burned. This process not only gives us energy but also helps get rid of waste like wood.
- You can cut your carbon emissions by up to 9.5 tonnes per year if you move from a coal or electric boiler to a biomass boiler.
- Biomass energy is a great way to get rid of wood waste. That means if you burn your wood instead of transporting it, the system can last even forever.
- The costs of regular fuels like petrol and oil keep going up, and this is not likely to change any time soon. One example is that the biomass needed for pellet boilers is less expensive, so your costs won’t go up by a lot. For heat, biomass costs about the same as petrol but a lot less than solid fuels and energy. This makes biofuel boilers a great option for these types of systems.
- Biogas boilers can get support from the Renewable Heat Incentive Scheme (RHI). This means that you will get payments over several years. This helps you pay back the initial investment in a shorter period of time.

Biomass Boilers Cons
- Because the system is bigger, biofuel boilers need more space than gas or oil boilers. You would also need somewhere to store the fuel, such as a hopper or wood shed.
- The fact that biogas boilers cost more to buy at first than gas or oil boilers is an important problem. This includes buying and installing the boiler. The cost of a biomass boiler is between £4,000 and £8,000. If you use a cheaper energy source, you will save money in the long run. The Renewable Heat Incentive helps cover the cost of the wood boiler.
- Biomass fuel must remain dry to burn efficiently. Therefore, storage conditions should be carefully considered.
- If you don’t have a hopper, a biomass boiler needs pellet chips added to it all the time. This makes it a little more work than a regular oil or gas burner.
- About once a week is enough time to clean a biomass boiler. But with modern models, the process is very simple or adds an element, so you won’t have to worry.
- To cut down on your carbon footprint and delivery costs, you should find a fuel provider that is close to you. Before you buy a biomass boiler, you should check to see if there are any nearby sellers. This is because delivery services don’t always work well in all areas.
How Much Does a Biomass Boiler Cost?
Your normal biomass boiler will cost around £16,000, but this can change based on a number of factors.
Cheaper models can cost around £12,000 but won’t be as hot as larger models. On the other hand, you could be paying around £22,000 for a water boiler that can splash and heat a very large house.
How much you pay for a biomass boiler will depend on a lot of things, like what kind of size, style, and automation you pick. For example, a log boiler that needs to be fed by hand will cost less than a pellet boiler that does it’s own feeding.
Below, you can see just how much size and automation impact the overall price of biomass boilers:
Type of biomass boiler | Average price range |
Small manually fed log boiler | £10,000–£13,000 |
Large manually fed log boiler | £13,000–£16,000 |
Small automatically fed pellet boiler | £15,000–£21,000 |
Large automatically fed pellet boiler | £22,000–£31,000 |
Bottom line
Before you decide, you should think about the pros and cons of biomass boilers. Installing a biomass boiler can cost more than installing a fossil fuel boiler. Also they are a safe and inexpensive way to heat water and heat homes. They often pay for themselves through RHI payouts and fuel savings. Make sure that your wood boiler is safe and working well.
People Also Ask
Biogas boilers can last for decades with proper maintenance, often outlasting traditional boilers.
Any type of home can use a biomass boiler, but you need to think about things like space and fuel availability.
Biofuel boilers can use a lot of different fuels, like sticks, chips, logs, and farm trash.
