Wood Pellet Comparison Guide

Choosing the right wood pellet can be a bewildering experience. We’ve attempted to compile some useful information below in a bid to make that choice slightly more informed. There are a number of manufacturers in the UK, some with multiple brands of pellets, so making sure that your pellet is right for you can be confusing. If you have a modern domestic pellet boiler one of the most important features of your pellet is going to be its certification. We strongly recommend only using an ENPlus A1 pellet in your boiler – see below for a note on the ENPlus scheme.

The ENPlus Scheme

The ENPlus certification scheme is more than just about spot testing the occasional bag of pellets to ensure that they ‘make the grade’. ENPlus is a quality assurance framework that ensures that appropriate quality control measures are in place throughout the manufacturing and bagging process, as well ensuring that appropriate spot tests are made!

Pellet Comparison – Animal Bedding Use1

Wood pellets make a fantastic animal bed – low in cost and quick and easy to do, they also perform well from a veterinary perspective as the manufacturing process destroys the spores that one finds in most other types of animal bedding. A common misconception about pellets is that they all perform the same when used as animal bedding – this couldn’t be further from the truth. In an attempt to cast some light of the relative performance of our pellets when used in this fashion we have tested the three most relevant factors, namely: Absorbency; Fluffiness and Dustiness. Please note that these tests should be considered a guide – these performance criteria will vary throughout the season as the inputs change, nevertheless we believe they faithfully reflect the performance of each pellet.

Fluffiness3 6.50m3/tonne8.63m3/tonne5.88m3/tonne
Dustiness4 1.75%2.13%2.13%

We think that, for animal bedding use, the Platinum Plus pellets is the clear winner. By far the most absorbent and fluffy pellet, it is also the lightest in colour!

If you’re after the ultimate in horse bedding wood pellets we strongly recommend you visit our sister company White Horse Bedding where you can read up about how to use wood pellet bedding and watch our informative video!

1. Please remember that when pellets are purchased for animal bedding use, the customer must select the 20% VAT option. Failure to do this could result in severe consequences if your books are audited by HMRC. For further guidance please see : http://www.whitehorseenergy.co.uk/vat-information
2. The percentage of the pellets own weight they are able to absorb when fully saturated; i.e. 294% means that 100g of pellets would weigh 394g when saturated. Bigger is better!
3. The volume of the pellets once activated; i.e. 6.5m3/tonne means that 100g of pellets will ‘fluff’ up to 6.5 litres once activated. Activated in this context means saturated with water so that the pellets completely break down, and then dried. Bigger is better!
4. This is the percentage, by mass, of the activated pellets that will pass through a sieve with 0.7mm gauge.

Wood Pellet Storage

When we hear of issues relating to performance with Wood Pellets they invariably come down to one of two problems: Dodgy boiler or poorly stored pellets! The vast majority of burning related issues tends to be a boiler that require servicing or cleaning. After that if we hear of an issue it tends to be that the pellets have been stored for a long time in less than suitable conditions – wood pellets really need to be stored in dry conditions. Because all wood pellet bags have micro pore holes in them to allow the contents to settle they will, if left in dank conditions, absorb moisture after a while. Our most troubling case so far was a pallet of pellets stored in a dry garage over the summer that had a moisture content reading of over 12% Only when we visited the premises did we discover that there was a tumble dryer in the same garage, spewing out moisture at the pellets! If you are intending to keep pellets for a long duration (over the summer say) please ensure that they are kept somewhere very dry. If in doubt order a half pallet at the end of winter!
