Powercorn 30-75kW Biomass Boiler

At the moment, we only install boilers in the UK. We specialise in installations within the Wye Valley.

Approved biomass fuel can be burnt in a smokeless zone, check here to see if your project is located within one,

Annual services of our boilers start at £440 (plus VAT).

You can control your boiler to 1°C and it’ll run at full efficiency (96%) even when it’s operating at 26% of its capacity. This results in a high turn-down ratio and biomass boilers can also be ‘cascaded’ within small district heating schemes and in larger buildings such as hospitals.

Yes, they are. Your boiler has a touch-screen control panel that allows you to regulate temperature, automatic running and fuel.

The ranges of boilers that we supply offer fantastic efficiencies (up to 96%), reduce CO2 emissions by up to 96% and can save you between 50-80% on your current fossil fuel bills. We only supply the highest quality boilers to guarantee you the best performance for your investment.

Our boilers require a twin-wall, stainless steel system.

After you have paid your deposit, the lead time is four to six weeks.

Indeed, but we do recommend using our services so that you can be sure all safety checks have been performed and that the boiler is set up to your specific requirements. You’ll also benefit from full training on how to look after your boiler, something our existing customers have really appreciated.

Most of our boilers require a 16amp power supply but some need a 13amp. To find out more about individual boilers, please feel free to contact us. We can supply you with circuit breakers and triple-phase adaptors.

We have covered the Renewable Heat Incentive here so have a read and let us know if you have any questions.

Our service comes with two years’ onsite warranty.

Because of the high levels of ammonia, we don’t recommend burning this as a biofuel.

Absolutely not, sorry!

Available widely throughout the UK, biomass is a low carbon fuel that’s renewable and brings fantastic environmental and social benefits. If managed correctly, biomass is sustainable and can significantly reduce net carbon emissions compared to fossil fuels.

The benefits of biomass are vast:

• Biomass is carbon-lean meaning it produces a fraction of the carbon emissions of fossil fuels. You can find out more here.

• Biomass can be sourced locally across the UK, on an indefinite basis. This contributes to the security of supply.

• UK-sourced biomass can provide opportunity and support the rural economy.

• Establishing local networks of production and usage minimises the financial and environmental costs of transport.There is no area within the UK that can’t produce biomass.

• Using biomass fuel provides a firm economic incentive for managing woodland which in turn improves biodiversity. To read more, click here.

• Many biomass fuels produce lower levels of atmospheric pollutants like sulphur dioxide, which contributes to acid rain.

• Biomass residues, co-products and waste that aren’t used for energy (or any other purpose) will usually rot. This will generate CO2 in any case, and could produce methane (CH4), a greenhouse gas which is 21 times more potent than CO2.

Wood pellets are made from compacted sawdust or any other waste produced from sawmills and other manufacturers.

It’s 4.8kWh per kg, meaning you only need one third of the storage space that you would need for chips. Plus you get three times as much heat.

• Wood Chips = 250KG/m3
• Wood Pellets = 650KG/m3

1 litre of oil is equivalent to 2kg of wood pellets.

You can expect to pay between £180 - £220 per tonne.

We always recommend using the fantastic Biomass Suppliers’ List (BSL) for a comprehensive list of high quality suppliers across the UK.

The pellets will need to be ENPlus A1 or A2. These are 10-12mm long and 6mm in diameter. Your wood pellets need to be dry, clean, mechanically robust and possess an ash content defined by appropriate standards. They need to be able to flow freely and delivered via a pneumatic system. Check out this handbook from HETAS for more information about wood pellets.

Passing small logs or wood waste through a chipping machine produces 3mm pieces (also known as G30). Find out more here.

Approximately 3.5 kWh per kg, depending on the moisture content of the chips. We recommend a maximum of 30% moisture and you can check this with a moisture meter.

Wood chips need approximately three times as much storage space as wood pellets;

• Wood Chips = 250KG/m3
• Wood Pellets = 650KG/m3

We always recommend using the fantastic Biomass Suppliers’ List (BSL) for a comprehensive list of high quality suppliers across the UK.

If you get bought-in wood chips, you can expect to pay £120 per tonne. Alternatively, if you have your own wood supply, you can arrange for contract chipping for around £50 a time. Contract chippers charge about £150 per hour and they can chip around 15 tonnes in an hour. So you can potentially chip your entire annual supply in half a day and load it straight into your fuel store.

Also known as ‘elephant grass’, Miscanthus is a perennial grass which grows and spreads quickly, even on land of poor quality. It’s so easy to cultivate and requires little to no intervention. This is why it’s such a popular option for biofuel.

Miscanthus has a calorific value of 3.6-4 kWh per kilogram and weighs 70-90 kilograms per metre cubed. It’s less dense than grain and therefore you’ll need more storage space.

The Guntamatic Powercorn and Powerchip models will both burn Miscanthus (in chopped or pelleted form). To ask about other models, please get in touch.

It’s imperative that Miscanthus is kept dry and ventilated to get the best out of it. Its moisture content cannot be above 20% and it must conform to W20 standards for chopped, air-dried Miscanthus and W30 for storing and drying.

We advise adding around 0.3 – 0.5% by weight of slaked lime (calcium hydroxide Ca(OH)2) to your fuel before using it in boilers with ratings up to 50 kW and 0.5 – 0.8% for boilers with ratings over 50 kW. This increases the calcium content of your fuel and raises the ash fusion point. This reduces the amount of clinker that can form.
