The term “biomass” carries with it a certain scientific connotation. Biomass is defined as any source of energy that originates from living organisms. This sustainable and renewable energy option uses combustion to produce heat. Biomass compounds can be made from a wide range of different biomass sources. Renewable energy sources, such as wind and solar, have the potential to supply all of our energy needs indefinitely.
Clearly, there is still a great deal to find out about this field. Just keep reading to find out!
What is Biomass?
Biomass refers to the fuel made from plant and animal material. With combustion as its fuel source, this method of producing heat is clean, sustainable, and kind to the environment. Wood scraps, leaf litter, crop residue, and animal byproducts are all examples of biomass sources. There is no question that we should prioritize using renewable energy sources like wind and solar because of their near-constant availability and potential for replenishment.
How is Biomass used in Stoves?
Biomass stoves provide their heat from biomass pellets or compressed wood. The burn tray mechanically and gently feeds fuel from the storage container, keeping the flame going strong (referred to as the hopper). Heating energy is released when biomass is burned.
Easy to operate?
Our biomass burners are controlled by thermostats and timers, just like traditional gas boilers. These thermostats are easy to use and come with a remote control, letting you set different temperatures at different times of the day. The stove may be managed remotely via a mobile device, allowing for adjustments to be made while you’re away from home.
Green Square pellet stoves offer:
- Reduced electrical power consumption
- High efficiency that is better than expected
- Easy to use because of the clearly laid out control panel.
- Constructed from modern-looking steel and iron.
- You can choose from a rainbow of colors!
- They are all quite effective while remaining silent.
- Obtaining a programmable thermostat for your own room is possible.
- Methods of Carbon Sequestration (MCS) and the Renewable Heating Initiative (RHI) (Microgeneration Certification Scheme).
Air and Hydro options
Most of our product lines can be purchased in either an air or hydro version. When set to the No-Air setting, air stoves do nothing more than heat the immediate area. Without using the fan on the stove, natural convection moves the warm air throughout the room. Hydro stoves can be used to efficiently and affordably heat an entire building’s heating system. You may use the same plumbing system to heat your hot water and radiators with hydro heaters.
How Does A Biomass Stove Works?
Defining what a biomass heater is and how it works. Maximum efficiency is achieved by maintaining a steady flame by carefully moving fuel from the storage container to the burn tray (called the hopper). Burning biomass releases the energy it contains, which can then be used to generate heat. Just like gas boilers, biomass burners include programmable thermostats and timers. A remote control can simplify routine chores and weekly temperature adjustments.
The stove can be controlled and adjusted remotely using a mobile device, meaning cooking may continue even when you’re not there. A great many of the models have both land-based and marine iterations. Alternatives to using a fan to circulate air around the stove and disperse heat around the room include the use of natural convection.
When it comes to heating an entire home, hydro stoves are preferable to boilers since they are more efficient and better for the environment. However, there is another way to heat the entire house that makes use of the existing plumbing and radiators.
Perhaps you’re curious about the inner workings of a wood stove or a pellet stove.
Advantages And Disadvantages Of Using Biomass Stoves
Heat and hot water can be generated using wood stoves and boilers, which employ organic materials for combustion (such wood logs, pellets, or chips) in order to warm the home and produce the necessary thermal energy. Conventionally, a single room is heated by a stove. On the other hand, a stove might be an external appliance or an integral part of a boiler. Hot water for the remainder of the home will also be provided at no cost. This essay will explain the benefits and drawbacks of building a comprehensive heating system.

How Much Does a Biomass Boiler Cost?
The cost of a biomass boiler will vary based on the type of fuel you plan to utilize and the method by which it will be fed into the boiler.
The table below compares the estimated prices of many different biomass heating systems.
As can be seen in the figure above, the price of a biomass log boiler can vary anywhere from £6,000 to $12,000. A log-fuelled boiler may be installed in a matter of days in most circumstances.
If you want to burn wood chips, you may either do it yourself or invest in an expensive mechanical equipment to do it. Wood chip stoves that must be manually fed can be purchased for between £4,000 and $10,000.
Wood chip boilers that are automatically fed can range in price from from £10,000 to £25,000. One to two days are needed to set up one of these alternatives.
Pellet biomass boilers provide efficient, affordable home heating while also being kind to the planet. If you don’t mind having to sometimes reload an auger or hopper, you may purchase a manually fed pellet boiler for between $5,000 and $10,000.
You may expect to pay anything from £10,000 to £25,000 for a biomass boiler outfitted with an automatic pellet feeder.
Pellet boilers can be installed in as little as one day, just like conventional biomass boilers.
What Affects the Cost of a Biomass Boiler?
We previously noted that biomass boiler prices might range widely. Here, we’ll examine in greater detail the variables that influence the biomass boiler installation price.
The Size of Your Home
It is not unexpected that the biomass boiler price would vary depending on the square footage of your home. There needs to be a much more powerful boiler installed in order to provide sufficient heat for your home.
The cost to run a biomass boiler could vary depending on the square footage of your home. If you want to make sure that every room in your house is the right temperature, you may need to leave your boiler running for longer than usual.
Boiler Output and Design
The price of a biomass boiler might vary depending on factors including its output and layout.
Consider a biomass boiler that can supply all of your home’s heating needs, no matter how big or small they may be, at the best value.
In all likelihood, the cost of your boiler will increase in line with its efficiency.
You should factor in the square footage of your home and your energy consumption habits when calculating the necessary output for your home. Between 15 and 56 kilowatts of power can be generated by a typical home biomass boiler (kW). A 15 kW biomass boiler should be able to easily heat a home with one or two bedrooms.

The price tag will shift based on the specifics of your biomass boiler’s blueprint.
The accompanying comparison chart shows the differences between manually and automatically feeding biomass boilers. The biomass boilers that use wood chips or pellets can be fed either manually or automatically, unlike the ones that use logs.
Boilers with automated fuel feeding can receive their fuel from either an on-site storage facility (above or below ground) or from the boiler itself (through an auger, hopper, or bagged pellets) (which allows you to buy bulk quantities of pellets or wood chips).
In terms of footprint, pellet boilers are vastly superior than their wood chip counterparts in terms of efficiency. Wood chip boilers are often larger than pellet boilers because of the massive auger required to feed the chips into the burner.
Smaller homes can also use pellet burners, one of the most cost-effective biomass heating choices.
Your Choice of Fuel
The biomass boiler you select will limit the types of fuel you can use, each of which comes at a different price.
Logs
Logs are more cost-effective than pellets or wood chips, but they need more work on your part because they must be manually fed into the biomass boiler on a regular basis, usually once a day.
Logs are often sold by the cubic meter rather than the tonne. Prices range from from $80 to $200 per cubic meter, depending on the type of wood used.
Hardwoods like oak, beech, ash, and birch are better for fireplaces because they are denser and burn for longer than softer woods like pine. How to choose the best wood for your biomass boiler is covered in detail by the Forestry Commission.
Wood Chips
Biomass fuels, such as wood chips, can be a cost-effective alternative if you have access to a forest and live in the country.
This, however, requires the use of a fuel-grade chipper. Including travel time, the average hourly rate to hire a chipper is over £200.
If you can’t gather your own wood chips, you might have to shell out £80 to £110 per tonne to buy them.
Wood Pellets
Pellets are used in biomass boilers because they are more efficient than logs or chips due to their higher density. However, pellets have the potential to store energy at a rate that is 3.5 times higher.
Due to their high cost, they are also the priciest biomass fuel option. Price estimates for pellets range from $160 to $225 per ton.
Cost-wise, you can choose between having the pellets blown to your storage facility, having them dumped onto your land, or having them delivered in bags (most expensive).
The Quantity of Fuel You Need
The annual cost of biomass fuel can be estimated by multiplying the boiler’s output by 4. If your biomass boiler is 15 kilowatts (kW), you will need roughly 3.75 metric tons of fuel each year (depending on your choice of fuel and energy consumption).
Pellets cost between £600 and £840 annually, but wood chips only cost between £300 and £410.
Logs for log boilers can be bought by volume, not by weight. To convert cubic meters of firewood to metric tons, just multiply by 1.38. There is a wide variation in annual fuel prices for a 15 kilowatt (kW) log boiler, from £410 to £1,035.
Regardless of the fuel type you employ, you should only ever purchase biomass fuels from a supplier that has earned HETAS or Woodsure certification. This ensures that your fuel is of high quality and does not contain any ash or harmful contaminants that could clog your boiler or pollute the air.
It is possible to find a reliable supplier by consulting the federal government’s Biomass Suppliers List.
Fuel Storage
Along with the price of the boiler and fuel, you’ll also need to budget for a dedicated fuel storage facility.
Since wet logs, chips, or pellets can’t be burned, it’s important to have a reliable biomass fuel storage system to keep the fuel dry and free of dust. A buildup of dust from the exterior could reduce the efficiency of your boiler.
Depending on the type of fuel you use and the quantity you need to store, you may be able to use an auger, a hopper, or an above- or below-ground storage system.
Adapting Your Existing Heating System
Changing to a biomass boiler from your current heating system could necessitate some renovations.
In order to prevent having to wait for hot water, for instance, you may need to invest in a hot water cylinder. This might cost anything from £850 to £3,500, depending on the make and size.
A heating expert can advise you on whether or not installing new radiators and pipes is necessary.
Maintenance and Servicing Costs
Burning biomass logs, wood chips, or pellets results in ash, but if you utilize high-quality fuel, your boiler should produce less ash. The ash container should be emptied every three to four weeks.
The ash has multiple applications, including as a fertilizer.
A biomass boiler servicing might cost anywhere from $180 to $450, depending on the size of your boiler, the type of fuel it uses, and your location. Biomass boilers should be serviced once per year. This may be much more common depending on how regularly you use them.
How Can I Save Money on a Biomass Boiler?
It’s easy to see how the cost of a biomass boiler may add up, but there are options to spread the payment out over time, or incentives for installation through programs like the Renewable Energy Incentive.
Consider Manually-fed Biomass Boilers
Manually fed biomass boilers have a significant economic advantage over automatic ones, to the tune of almost $15,000.
Automatic feeding eliminates the need for careful monitoring while they are being refilled.
Look For Secondhand Biomass Boilers
The occasional decommissioning of a biomass boiler is something that can happen in both private households and commercial businesses. In light of the high cost of new biomass boilers, it may be worthwhile to investigate the few stores that still offer older models.
Be cautious about buying a used biomass boiler without first doing your research.
- How much more does it cost to set up a biomass boiler than a new one?
- In that case, how long does the guarantee last? To what extent does this continue?
- Can you tell me about the RHI tariff I can anticipate receiving?
Energy Savings

Please note that the goal of this guidebook is purely educational. These figures are based on the conversion of an existing heating system in a detached four-bedroom house to a biomass pellet boiler and on basic insulation. This data was collected by the Energy Savings Trust.
It’s not as true as you may believe that upgrading to a newer heating system will save you money if you’re replacing an older one (such as a gas, oil, or LPG boiler). Switching from an A-rated gas or oil boiler to a biomass boiler could end up being more expensive.
The additional cost of a biomass boiler needs to be weighed against the benefits of a smaller carbon footprint. Carbon dioxide (CO2) emissions from home heating can be greatly reduced by replacing an outdated gas, oil, or LPG boiler or a coal boiler with a biomass boiler.
Converting to a biomass boiler or having one installed in a new home is a great way to lessen your impact on the environment.
To save more than £110 annually, you must have an oil boiler that is at least 10 years old (and hence an A rating) and replace it with a biomass boiler. By replacing your current heating system with a biomass heater, you may save up to £335 annually.
Northern Irish residents can find money-saving tips on the website of the Energy Saving Trust.
Surplus Heat
Those who participate in a heat network may be able to make even more money by selling off their unused heat to others in the network. Up to 8.5 pence per kilowatt-hour (kWh) is available to homeowners for the heat they generate and consume.
In order to qualify, a home or business must have an approved renewable heat source installed. Biomass boilers are one example; they create heat from non-fossil sources like wood pellets, maize husks, or logs.
There are two main reasons why customers are finding it financially beneficial to install a biomass boiler in their home:
- in terms of saving money on petrol.
- This monthly stipend is provided by the Renewable Heat Incentive.
It’s important to keep in mind that biomass boilers are a premium product, and that the added bonus of producing eco-friendly heat is marginal. Boilers are cost-effective even without the RHI rebates since they cut fuel costs.
Biomass-burning water heaters, furnaces, and other components are healthier for the environment and a huge step toward self-sufficiency.
Are Biomass Boilers Expensive to Run?
