Biomass Heating Advantages and Disadvantages
With the constant rise in oil and fossil fuel prices, many people have started looking for alternative ways to heat their homes and businesses. One option gaining popularity is investing in wood pellet or wood chip boilers. Wood pellet and wood chip heating is a new and modern solution consisting of various decorative stoves and boilers for your home or business. As with any heating system, the advantages and disadvantages of biomass boilers are numerous, which is why we constantly evaluate the quality and cost-effectiveness of the boilers we supply.

The Pros of Biomass Boilers
They run on a renewable energy source called biomass fuel (wood pellets, wood chips and wood logs) which is good for the environment.
They can be very efficient and produce heat for both domestic and commercial buildings.
Biomass fuel is cheaper than traditional fossil fuels, protecting you from price increases and saving you money in the long term.
The Cons of Biomass Boilers
They require a lot of space, so they may not be suitable for all buildings. If you want to know if you have enough space to install a biomass boiler, please contact us.
The initial cost of installing a biomass boiler is high but can be offset by signing up for the Renewable Heat Incentive scheme in the UK.
Depending on your area, getting a steady supply of biomass fuel can be difficult. Innasol acquired Y-Pellets to provide biomass fuel to customers throughout the UK.
What is Biofuel?
Biofuel is a renewable source of energy developed from organic matter such as wood, plants or plant-based materials which are not used for food or feed. Biomass fuels can be used to generate electricity, heat, and transportation fuel. They are considered renewable energy sources because they can be replenished naturally through photosynthesis. The most common biomass energy source is wood, in the form of logs, pellets or wood chips.
Thinking of getting a Biomass Boiler?
It can seem daunting to switch from a conventional fossil fuel heating system like an oil or gas boiler to a renewable energy source such as biomass energy. There are various advantages and disadvantages of Biomass Boilers. We want our customers to be fully informed and comfortable before upgrading to a biomass heating boiler from us. We have created a list of the pros and cons of biomass boilers because switching to a renewable energy source for your home or business, like biomass, has some advantages and disadvantages.
What are the benefits Of Biomass Boilers?
- Cost-effective and eco-friendly solution
One of the first advantages of biomass heating is its cost-effectiveness. Biomass power is a carbon-neutral energy generated from renewable organic waste that would otherwise be dumped in landfills, openly burned, or left as fodder for forest fires. Replacing a coal or electric heating system with a biomass boiler can help the average household reduce its carbon dioxide output by up to 9.5 tons annually.
- Fuel prices are stable when compared to fossil fuels generating additional savings with less geopolitical risk
Prices of traditional fuels like oil and gas are steadily increasing, and this tendency is not expected to change anytime soon. Biomass wood fuels have much more stable prices, so you will not see your bills increasing sharply.
- Use up waste wood
Biomass energy is a great way to dispose of waste wood. If you live or run a business in a rural location, chances are you have access to an ample supply of wood to burn. This means a new biomass system is even more sustainable as you will burn local wood instead of delivering it.
- Perfect for off-grid locations
Another of the biomass advantages is that you don’t need to be connected to utilities. Biomass boilers are a perfect off-grid solution for both heating and hot water.
- It works like your fossil fuel heating system and can manage both your heating and hot water
Biomass boilers are very similar to conventional gas boilers, providing you with space heating and hot water for the property. Instead of using gas (or oil) to produce the heat, biomass boilers combust sustainably sourced wood fuel.
What are the disadvantages of Biomass Boilers?
- Space
A biomass boiler can be considerably bigger when compared to fossil fuel boilers, and in most instances, space for a fuel store also needs to be considered.
- Upfront costs can be quite expensive, although long-term savings and RHI counter this.
Installing a biomass boiler is not cheap. Domestic biomass boilers usually start at around £10,000, and commercial biomass boilers can cost considerably more so overall it is a big investment. However, this should be balanced with the potential long-term savings in energy costs and the financial incentives on offer. The savings on energy and the RHI can mean that the investment has been recovered within a few years. For people with off-grid holiday home businesses and land-based businesses such as farms, generating an annual income and low energy costs is desirable.
- This type of boiler requires some maintenance
Although not overly demanding, biomass boilers will require some maintenance. Even if most modern boilers include self-cleaning systems, the heat exchanger must often be brushed to have the highest working proficiency. Additionally, ash bins need to be regularly emptied, and if you don’t have an automatic feed, it will require you to top up your wood pellets. As with all heating equipment, regular servicing is recommended.
- Access to the delivery lorry for fuel supply should be considered
As with any large delivery, access to your property will need to be considered. Many biomass boilers are auger-fed so you only need to get within a few metres of the fuel store.
- Fuel quality can be more variable than fossil fuels
Good wood chips will have been processed from seasoned wood and should contain a moisture content and particle size that matches the requirement of the boiler it is intended by used with. Low-quality chips may damage the appliance and reduce its reliability considerably. Typically, larger boilers (greater than 1MW) are designed to be more robust, with a higher tolerance to lower-grade chips. Wood pellets and wood chips are quality-graded. Biomass boilers must use specified fuels for the manufacturer’s recommendations.
Biomass Boilers advantages and disadvantages
There are several advantages of biomass energy over traditional fossil fuels like gas and oil heating. Firstly, it is a renewable source of energy, generated from burning wood, and other organic matter, such as wood pellets, wood chips or wood logs. Biomass energy emits fewer harmful byproducts, which means cleaner air and healthier people. Moreover, biomass energy is a widely available resource and is less expensive, making it an attractive alternative to fossil fuels. Using biomass energy also reduces the amount of garbage in landfills, as organic waste can be used to generate energy instead of being disposed of in landfills.
It is important to remember that biomass energy some several disadvantages that must be considered when getting a biomass boiler. One of the biggest concerns is that it may not be easily accessible to everyone, especially to those in urban areas where accessing biofuel can be difficult. It also requires a lot of storage space to safely store the wood pellets, wood chips or logs without them getting wet. There are several pros and cons of biomass energy, when making a decision about switching from oil heating or oil boiler. We recommend getting in touch with a qualified expert that can explore all of the options available to you based on the size of your home or business. At Innasol our team of experts will be able to survey your building to identify the most suitable biomass boiler for you and the most appropriate fuel sources dependant on your area.
How is Biomass fuel made?
As we weigh the pros and cons of biomass, it’s important to know “How Biomass Heating Works” and “How biomass fuel is made”.
Biomass fuel is made by compressing the sawdust and woodchips (byproducts from sawmills) into a fine powder that is dried and pressed to make wood pellets. These wood pellets are high-energy fuels that produce low emissions and waste.
Fun fact, every 100kg of pellets burned produces less than 700g of ash, less than a sugar bag. Watch this quick, 4-minute video on biomass and how it works.
Summary
Biomass is still comparatively small in the UK with biomass boilers heating fewer than 5% of the UK’s homes. Biomass is an untapped resource that can be very versatile and used as a fuel for electricity, heat and transport as well as industrial material production. The boilers are a cost–effective and eco–friendly solution for heating a domestic or commercial building. They offer stability in fuel prices and the potential for earning money through the Renewable Heat Incentive scheme. While there are some disadvantages to consider, such as the upfront costs, space requirements and maintenance, the advantages of biomass boilers often outweigh the cons.
Biomass energy is a renewable energy source developed from organic materials such as wood, plants or plant–based materials which are not used for food or feed. Investing in wood pellet or wood chip boilers is gaining popularity as an alternative to traditional fossil fuels, as they burn cleanly, offer stability in fuel prices, and can be used to generate electricity, heat, and transportation fuel. They can also earn money through the Renewable Heat Incentive scheme. However, they require a lot of space and have a high initial cost, and may not be suitable for all buildings.
