Description
ENVI8 Briquettes – Long-Burning Hardwood Fuel Blocks
ENVI8 briquettes are large, dense hardwood blocks made for big stoves with plenty of room in the firebox. Each block weighs around 1.5kg and provides a long, hot burn once the fire is properly established.
These briquettes can’t be broken into smaller pieces, so they won’t suit most small stoves. Please check the dimensions carefully before ordering to make sure they’ll fit your appliance.

What are ENVI8 briquettes made from?
ENVI8 briquettes are made from clean, kiln-dried oak and hard maple sawdust produced while hardwood timber is being prepared for other industries.
Trees aren’t felled specifically to manufacture these briquettes. The product makes practical use of clean hardwood material that would otherwise be left over from timber processing.
There are no chemicals, additives or artificial binders. The blocks are held together by compression alone.
What are ENVI8 briquettes like to burn?
ENVI8 provides a long, hot burn when added to an established fire.
The size and density of each block make it particularly useful for keeping a large stove going without having to add fuel constantly. This makes ENVI8 a good choice for bigger, fuel-hungry appliances.
Burn time will vary depending on your stove, chimney or flue, and airflow settings.
Which stoves are ENVI8 suitable for?
ENVI8 is designed for larger stoves with spacious fireboxes.
Each block measures approximately 240mm × 80mm × 70mm and weighs around 1.5kg. The blocks are extremely dense and can’t be broken by hand, so check the available space in your firebox carefully before ordering.
ENVI8 will be too large for many smaller stoves. If you need a fuel that can be divided into smaller pieces, another briquette from our range will be more suitable.
If you’re unsure which fuel will suit your appliance, try our Wood Briquette Finder.
Can I break ENVI8 into smaller pieces?
No. ENVI8 blocks are extremely dense and can’t be broken by hand.
This density helps them provide a substantial, long-lasting source of heat, but it also means the complete block must fit comfortably inside your firebox.
Don’t attempt to force an oversized block into your stove. Choose a smaller or more easily broken briquette if space is limited.
How should I use ENVI8?
ENVI8 works best when added to an established fire.
Begin with a natural firelighter and kindling. Once the starter fuel is burning properly and you have a good ember base, add an ENVI8 block and allow it to catch.
Its size and density will then help provide a long, hot burn. Avoid overloading the stove and always follow the appliance manufacturer’s instructions.
Can ENVI8 be used for overnight burning?
ENVI8 is suitable for longer burns, and some stoves may remain warm overnight when these blocks are used.
The result will depend on your particular stove, chimney or flue, and airflow settings. Never try to extend the burn by closing the airflow until the fuel smoulders. Smouldering produces more smoke and particulate matter and can cause deposits to build up inside the stove and flue.
For safe overnight use, always follow the instructions provided by the manufacturer of your appliance.
Can I burn ENVI8 with other fuels?
Yes. ENVI8 can be combined with other suitable wood fuels.
A quicker-lighting briquette, dry kindling or another approved starter fuel can be used to establish the fire. Once it’s burning properly, add ENVI8 to provide longer-lasting heat.
Only burn fuels approved by the manufacturer of your appliance.

How should ENVI8 be stored?
ENVI8 briquettes must be kept completely dry.
A dry garage, watertight shed, porch, conservatory or dry outbuilding is suitable. The packs can also be kept inside your home or in a watertight plastic garden store.
Don’t keep them in a traditional open-sided log store, an uncovered outdoor area or a damp building. Briquettes are already very dry and readily absorb moisture. If they become damp, they’ll begin to expand and can eventually turn back into sawdust.
Is the packaging waterproof?
No. The plastic wrapping around each pack is mainly there to hold the blocks together. It may have small gaps and shouldn’t be treated as waterproof.
The complete pallet is also plastic wrapped for protection during transport. This provides some temporary protection from poor weather during delivery, but it isn’t suitable for outdoor storage.
Please make sure you can move the packs under cover when they arrive. Check with your local authority to find out whether the plastic packaging can be recycled in your area.
Is delivery included?
Delivery to most UK mainland postcodes is included in the pallet prices shown.
Some mainland and offshore addresses carry an additional surcharge. Enter your postcode using our postcode checker to confirm the delivery charge for your address.
Express Packs are sent separately by parcel courier. You can read more about this service in our parcel delivery information.
Pallet orders are delivered by our pallet courier, Palletline, rather than by one of our own vehicles. Pallet delivery normally takes three to five working days for most areas, and someone must be there to receive it.
How will my pallet be delivered?
Delivery is made at the kerbside using a tail-lift vehicle and pallet truck.
The pallet footprint is normally approximately 1.2m × 1m. The driver needs a firm, flat and level surface on which to unload. A pallet truck can’t move safely over gravel, grass, slopes, steps or uneven ground.
Deliveries are normally made on an 18-tonne lorry. As a rough guide, if a bin lorry can reach your property, an 18-tonne delivery vehicle should be able to as well. The driver will make the final decision about whether it is safe to enter your road.
The pallet will normally be left at the kerbside or where your bins are placed for collection.
What if access to my property is restricted?
If you need a smaller 7.5-tonne vehicle, your order must weigh no more than 720kg.
A quarter, half or three-quarter pallet of ENVI8 can be carried on a 7.5-tonne vehicle. A full pallet weighs approximately 864kg and requires suitable access for an 18-tonne vehicle.
A 7.5-tonne vehicle is the smallest delivery vehicle we can request. If you need one, select the Access Restrictions option at checkout and add a note asking for a 7.5-tonne vehicle.
Why choose ENVI8 briquettes?
ENVI8 is made for customers with large stoves who want a substantial, long-burning hardwood block. Its size and density provide plenty of heat and help reduce how often a fuel-hungry stove needs to be refuelled.
The blocks are made from oak and hard maple sawdust, produce less than 1% ash and contain no artificial additives or binders.
ENVI8 is an excellent choice for a large appliance, but it isn’t suitable for most small stoves. Check the dimensions of your firebox before ordering to make sure the blocks will fit comfortably.
