Biomass Boilers – Renewable Heating Solutions in Cornwall

What is a Biomass Boiler?

Biomass boilers are renewable alternatives to gas and oil boilers. Primarily, biomass boilers are fueled by substances such as wood logs, pellets, and chips. They provide 100% of space heating and hot water demand to domestic and commercial buildings.

Replacing expensive, harmful fossil fuels, biomass boilers offer more affordable, sustainable heat supply. As a result, customers are able to reduce their heating bills and carbon footprint.

How does a Biomass Boiler work?

Biomass boilers burn wood substance to generate heat. Opposite to traditional log-burning stoves where heat is lost up a chimney, for example, biomass generates heat for distribution through a central heating system. Both radiators and underfloor heating are compatible. Biomass system are 90%more efficient than heating stoves.

Unlike other renewable alternatives, biomass requires user interaction.

As biomass boilers burn wood, the system needs to be loaded. Typically, modern biomass solutions come with an attached hopper that feeds the chips, pellets or logs into the stove and keeps loading to a minimum. More sophisticated boilers are self-loading and capable of monitoring the amount of fuel in the system and the rate of supply to ensure operate performance.

Types of Biomass Boiler

Wood Pellet Boilers

Wood pellet biomass boilers are fueled by high-density wood pellets. Pellet boilers are virtually carbon neutral and around 50% cheaper to run than oil, LPG or direct electric systems.

More information on wood pellet biomass boilers can be found on our ‘Wood Pellet Boilers‘ page.

The benefits of Biomass Boilers

Biomass boilers offer some of the most biggest benefits of any renewable solutions, both financially and environmentally.

Reduced Heating Bills

Despite the upfront cost of supplying the wood fuel, rises in the price of fossil fuels have led customers to look for cheaper heating alternatives.

Biomass boilers offer much cheaper running costs than traditional solutions. By replacing non-renewable demand, customers switching to biomass can save up to 50% on their annual heating bills. In addition, replacing fossil fuels with naturally occurring materials provides customers with protection from unstable energy prices.

The Renewable Heat Incentive

Customers installing biomass also benefit through Renewable Heat Incentive.

The government started the Renewable Heat Incentive, or RHI, to encourage the uptake of renewable heating technologies. The scheme aims to bridge the gap between the cost of traditional heating systems and renewable alternatives. In effect, the scheme pays customers for the renewable heat generated by their system.

Both domestic and commercial customers can apply for RHI payments. The rate of pay depends on the technology installed, the amount of heat generated by the system and the efficiency building in which it’s installed.

We estimate that energy savings made by  switching to biomass combined with RHI payment mean an installation will repay itself in around 7 years.

More information on the RHI scheme can be found on our ‘Renewable Incentives’ page.

Environmental Impact

Replacing heat demand from the grid with naturally occurring materials will lower the carbon footprint of a home or business.

Not always the primary driver, reducing carbon footprint by going green shows a commitment to protecting the environment that is desired by home and business owners.
GreenGen calculates that a domestic biomass installation will reduce annual carbon output by as much as 50%.

Will a Biomass Boiler suit my property?

Customers thinking of switching to biomass need to keep a few considerations in mind:

– Biomass boilers are larger than gas or oil systems and. as such, require more space. Generally speaking, the larger the size of the property the larger the heat demand will be. The larger the heat demand the larger the biomass boiler is likely to be.

– Customers also need space to store their fuel. In order to minimalise deliveries and disturbance, a large, sheltered store is advised. Sheltering the store keeps moisture levels low and heightens performance.

– Manual handling of the wood fuel is required. Customers should be aware of the physical and time implications when considering a biomass boiler.

– A flue is required as part of a biomass installation. Some biomass boilers come equipped with a flue while others require additional incorporation.

– Although biomass boilers provide heat at higher temperatures than other renewable alternatives, it’s important that the central heating system can provide enough heat. As such, alterations may be required.

– As with traditional boilers, biomass boilers need regular servicing. Servicing ensures high performance and validates warranties. We offer several service packages that provide varying levels of cover to new and existing customers.
