You won’t find our unique Finnish combined heat and power (CHP) solutions anywhere else in the south west.
We are the region’s sole distributor for the ArborElectroGen® 45.
Finnish technology and design
The ArborElectroGen® 45 delivers greater kilowatt hours per square metre than any comparable system on the market with 45kW of electricity and 100kW of heat.
It works by generating heat and electricity from woody biomass and offers better returns than heat-only biomass technologies.
What’s great about this unique system, the first professionally-packaged small-scale biomass CHP unit in the UK, is how easily it integrates into existing heating systems.
Versatile enough to be placed indoors or outdoors (with various weatherproof specifications), this unit enables your business to be both green and lean, with return on investment expected within five years at standard usage rates.
How it works
Now for the detail… The fuel required is dry (15% MC – dry basis) wood chips. These are fed into a system of chain conveyors and augers and gasified with limited air to retain a unique level of high energy in the gas.
Easy maintenance: Before the tar-free gas is allowed into the engine, it is cooled. The 8.4 litre six-cylinder engine also has an automated cleaning function, making it easy to maintain.
Tariff-compliant: Qualifying for the Biogas combustion non-tiered flat rate tariff, the unit derives its 82 Kw heat from five sources which the system automatically mixes to maintain output. Radiant heat (up to 20kw) from the gasifier cabinet is also captured.
Power generation: Power is from a generator in the engine housing. A grid-feeding unit enables export and parallel operation on the National Grid as well as energy use by the customer.
Battery storage: This unit can also be specified to manage battery storage, making off-grid installations available in pre-packaged options.
Metering: Metering is installed as standard. With high quality energy content of the syngas produced, Arbor systems qualify for the highest ROC banding available under the Advanced Gasification tariff.
Biomass CHP fuel – woodchip
The ArborElectroGen 45 runs on sustainably sourced dried woodchips, which are gasified at a high temperature. Biomass CHP is considerably better for the environment and cheaper than using fuels such as oil, wood pellets or LPG.
THE BENEFITS OF WOODCHIP
- Woodchip is the cheapest form of timber fuel
- It’s easily obtainable
- Requires minimal processing
- The chips can be delivered by the supplier straight
into an automatic processing system, keeping
handling to a minimum
The woodchips must be made from virgin softwood timber such as birch, spruce, pine or aspen, dried to around 15% moisture content. The woodchips must be G50 grade with the finings removed in order to make automated handling easier and allow sufficient space between the chips for the process of gasification to occur.
Many Biomass CHP owners choose to buy moist woodchip and dry it before use using some of the heat from their plant. Moist woodchip can be around 50% cheaper than pre-dried woodchip. It is also possible to chip your own timber, as long as the chips meet the manufacturer’s specification.
As part of the system design process Ignis will consider your fuel storage and delivery needs to develop a strategy for the easiest and most cost efficient way to source your fuel. We will also assist you in finding a local fuel supplier to minimise the cost of delivery to your site.
Woodchip fuelled Biomass CHP systems emit around 93% less CO2 than equivalent LPG systems.

These can be made from almost any kind of wood including whole trees. It has a low bulk density, meaning that wood chip requires a bigger storage space.
Moisture content should also be considered when using wood chip; a higher moisture content will not be efficient as some of the heat will be used when the moisture is vaporised.
Logs need to be seasoned to be energy-efficient. Unseasoned logs contain a lot of moisture, so do not produce as much heat. Almost any tree can be used for fuel: soft woods do not produce as much energy as hard woods, meaning that larger quantities of soft wood are needed to produce the equivalent amount of energy provided by hard woods.
Consider the source of your logs and where you will store them to keep them dry.
These can be produced from wood by-products such as sawdust and waste but may also be produced directly from the tree.
Pellets are the most convenient type of wood fuel, having a very low moisture content, being very efficient, producing less ash and requiring a smaller storage space due to their high bulk density. Good quality pellets will provide greater heat.
With CHP you’re eligible for three revenue streams. This is a long-term investment for years to come with a return on investment in under five years.
