Switching to biomass boilers or stoves is one of the most practical steps a home or business can take to cut carbon emissions without sacrificing comfort or reliability. Wood pellet boilers and biomass stoves deliver heat on demand, run on sustainably sourced UK fuel, and cost far less to operate than most people expect. If you are still running on oil, LPG, or gas, here is what you need to know.
What Is Biomass Heating and How Does It Work?
Biomass heating uses organic material as fuel in place of oil, gas, or LPG. For domestic and commercial heating systems, that material is almost always compressed wood pellets: a dense, low-moisture fuel that burns cleanly and efficiently. The heat produced is then delivered to your property either through a central wet heating circuit or directly into a room, depending on the type of system you install.
There are two main options: a biomass boiler or a biomass stove. They share the same fuel but work differently and suit different needs.
What Are Biomass Boilers?
A wood pellet boiler operates on the same principle as a conventional oil or gas boiler. It burns wood pellets to heat water, which then circulates through your existing radiator system or underfloor heating. From a user perspective, the experience is close to identical to a conventional boiler: the system is fully automatic, manages its own output, and can be controlled via a standard thermostat.
The key difference is the fuel feed. Wood pellets are stored in a dedicated hopper or bulk store adjacent to the boiler room and fed automatically into the combustion chamber via an auger. Bulk deliveries are blown directly into the store, so there is no manual handling between deliveries. Ash output is minimal, typically requiring the ash bin to be emptied once a month.
Wood pellet boilers from Land Energy are ENplus A1 compliant, carry a guaranteed minimum output of 4,800 KWh per tonne, and demonstrate a net carbon saving of 85% or more over oil, well ahead of the European benchmark of 60%.
What Are Biomass Stoves?
A biomass stove burns wood pellets to heat the room it sits in directly. Unlike a boiler, it does not connect to a wet heating circuit, so it does not feed radiators or underfloor heating in other parts of the building. Heat is delivered through a combination of radiant warmth and, in most modern pellet stoves, a fan that circulates warm air into the room.
Pellet stoves are automated to varying degrees. Most have a hopper that holds enough fuel for several hours of continuous use and a thermostat or timer control. They require a lined flue and adequate room ventilation, but do not need a boiler room or bulk pellet store.
Biomass stove installation is considerably simpler and less expensive than a full boiler installation, making it a practical choice for supplementary heating or for properties where a whole-home system is not required.
Biomass Boilers vs Biomass Stoves: Which Is Right for You?
| Biomass boiler | Biomass stove | |
|---|---|---|
| Heats whole property | ✓ Yes | ✗ No |
| Connects to radiators | ✓ Yes | ✗ No |
| Fuel storage needed | Bulk store or hopper | Small onboard hopper |
| Installation complexity | Higher | Lower |
| Best for | Replacing central heating | Supplementary or room heat |
For whole-home or whole-building heating, a wood pellet boiler is the right solution. For supplementary or room-level heat, a biomass stove installation is a simpler, lower-cost option.
What Do I Need to Install a Wood Pellet Heating System?
This is one of the most common questions we hear, and the honest answer is: less than most people think.
For a wood pellet boiler, you will typically need:
- A pellet store (a purpose-built hopper or bulk bag store adjacent to the boiler room)
- A flue or chimney suitable for a biomass appliance
- Space for the boiler unit itself, which is larger than a conventional gas boiler
- A compatible heat distribution system (radiators or underfloor heating)
- An MCS-accredited installer
For most residential and commercial properties, an existing oil boiler room can be adapted without major structural changes. The fuel delivery process mirrors an oil delivery: bulk pellets are blown directly into the store, so there is no manual handling involved.
For a biomass stove installation, the requirements are simpler: a suitable hearth, a lined flue, and adequate room ventilation. Many existing fireplaces can be adapted.
In both cases, Land Energy’s installation team will assess your property and specify the right system before any work begins.
How to Switch Your Home Heating to Biomass Energy
If you are asking how to switch to biomass heating, the process follows four straightforward steps:
- Assessment: A surveyor visits your property to assess your current heating setup, heat demand, and available space for a pellet store and boiler.
- System specification: The right boiler size and fuel storage configuration are specified for your property.
- Installation: A qualified, MCS-accredited engineer installs the system, connects it to your existing distribution network, and commissions it.
- Fuel supply: Once live, you arrange regular bulk pellet deliveries. Land Energy pellets are ENplus A1 certified and available across the UK through our distributor network.
The renewable home heating switch can typically be completed within a few days for a straightforward residential installation. Commercial projects vary depending on scale.
The Case for Switching: Key Benefits of Biomass Boilers
1. Ease of use
Wood pellet boilers are fully automatic. Pellets feed from the store into the boiler via an auger system, and the boiler manages its own output. There is no manual topping up between deliveries. The experience is as close to a conventional boiler as biomass gets.
2. Low maintenance
Ash output from a wood pellet boiler is minimal. For most installations, emptying the ash bin once a month is sufficient. No day-to-day intervention is required.
3. Environmental performance
Wood pellets from Land Energy are 100% UK sourced, produced within 60 miles of our Girvan plant, and manufactured using zero fossil fuel inputs. A wood pellet boiler can demonstrate a net carbon saving of 85% or more over oil, well ahead of the European benchmark of 60%.
4. Running costs
Wood pellet boilers run at 85%+ efficiency. Operational and servicing costs are comparable to a conventional oil boiler, and routine maintenance can often be carried out by on-site staff.
Who Can Switch to Biomass Heating?
Biomass heating is suitable for a wide range of properties and sectors. Land Energy installs and supports systems across:

FAQs
1. How long does it take to switch to biomass heating?
For a straightforward residential installation, switching to biomass heating typically takes two to three days. This covers the removal of the existing system, installation of the wood pellet boiler, connection to your existing radiator or underfloor heating circuit, and commissioning. Commercial installations vary depending on the scale of the project and the complexity of the fuel storage setup. Land Energy’s installation team will give you a clear timeline following the initial property assessment.
2. Can I switch to biomass heating if I am already on the gas grid?
You can, but biomass heating delivers its strongest financial case for properties that are off the gas grid and currently running on oil or LPG. For on-grid properties, the cost difference between gas and wood pellets is narrower, so the payback period on installation is longer. That said, the carbon saving case remains strong regardless of your current fuel. If reducing your carbon footprint is the primary driver, biomass is worth considering for any property with adequate space for a pellet store.
3. What is the difference between a biomass boiler and a biomass stove?
A wood pellet boiler connects to your wet heating system, heating water that circulates through radiators or underfloor heating across the whole property. A biomass stove heats a single room directly by radiating heat into the space and does not feed into a central heating circuit. Biomass stove installation is simpler and less expensive, but it is not a whole-home heating solution. If you want to replace your central heating system, a wood pellet boiler is the right choice. If you want supplementary heat in one room, a stove is a practical and cost-effective option.
4. Are Land Energy wood pellets suitable for all biomass boilers?
Woodlets wood pellets from Land Energy are ENplus A1 certified, which is the quality standard specified by the majority of biomass boiler manufacturers. ENplus A1 pellets meet strict requirements for moisture content, ash content, calorific value, and durability, meaning they are compatible with virtually all wood pellet boilers on the market. Land Energy pellets also have an exceptionally low ash content of typically under 0.2%, which reduces the frequency of ash removal and keeps boiler maintenance costs low.
5. Is biomass heating eligible for any government incentives?
Wood pellet heating systems installed by MCS-accredited engineers using BSL-registered fuel are eligible for the Boiler Upgrade Scheme (BUS) in England and Wales, which currently offers a £5,000 grant towards the cost of a biomass boiler installation. Land Energy pellets are listed on the Biomass Suppliers List (BSL), meaning customers can meet their RHI and BUS compliance requirements using our fuel. Eligibility criteria and grant values can change, so it is worth checking the current scheme terms with your installer or via the government’s official guidance before committing.
6. How do I switch my home heating to biomass energy?
Switching your home heating to biomass energy follows four steps. First, a surveyor visits your property to assess your current heating setup, heat demand, and available space for a pellet store and boiler. Second, the right boiler size and fuel storage configuration are specified for your home. Third, a qualified, MCS-accredited engineer installs the system, connects it to your existing radiators or underfloor heating, and commissions it. Fourth, you arrange regular bulk pellet deliveries to keep the system running.
For a typical residential installation, the work is completed within two to three days. Your existing boiler is removed as part of the installation process. Planning permission is not usually required for an internal boiler replacement, though a biomass stove installation that involves external flue work may need permitted development approval depending on your property type and location.
