Introduction

When purchasing firewood, the quality can vary massively. One company may supply logs that are bone-dry and ready to burn, another company may supply damp logs that sometimes even have mould attached!

It’s essential to take your time when choosing a firewood supplier.

The two most important aspects we think customers should consider are whether the logs come from a sustainable managed forest. For example, does the wood come from a forest that is FSC certified?

The next factor is whether the logs have been dried correctly and have a low moisture content.

This can mean the burning performance of the logs can vary massively depending on where you purchase your logs. One company for example may sell logs that will leave very little ash in the wood burning tray, the ash left is then fine. This can often mean that the wood has been burnt hot and correctly.

For another business that sells wet logs, you may be stuck for an extended period trying to ignite the wood. Then, an excessive amount of smoke may emerge from the chimney! The ash left in the wood burning stove can be excessive and the soot can actually damage the stove and the environment.

Therefore, you do have to choose your log suppliers carefully.

In this article, we will discuss some of the firewood certifications available to ensure that you are getting high-quality try logs or purchasing a quality wood burning stove. Also, it’s essential to buy logs from a sustainable source as well.

 

FSC Forest Stewardship Council

When you see FSC certification on a pack of logs or a log supplier’s website, this means that the company has sourced its logs from a supplier that is committed to responsible forest management.

Being FSC certified means that the company is committed to sustainable forest management.

If the forests from which the timber is sourced are responsibly managed, this means that there will be trees to fell in the future to produce wood or solid fuels again.

 

HETAS Certification

You may see a HETAS sticker applied to wood-burning stoves as well as fuels. Some customers may not know what this sticker or logo means—having a product that is HETAS-certified means that the product has been produced to work efficiently and to be environmentally friendly.

It is therefore a sign of quality if you are buying, for example, fuels that are HETAS certified.

 

Woodsure Certified

As we mentioned earlier in this article, purchasing wet wood can be both annoying for customers and harmful for the environment. Damp wood, that’s wood with a high moisture content, simply produces an excessive amount of smoke.

Instead, you want the logs to be as clean-burning as possible.

Therefore, many log suppliers in the United Kingdom hold Woodsure Certification, ensuring that the firewood or biomass fuels are of good quality.

 

Buy quality

There will always be log suppliers that compete solely on price. However, it’s important to note that if the wood is not correctly dried, it will not produce the heat that the customer would expect from the logs or kindling.

Wet wood can therefore be a total false economy.

However, as this article illustrates, not all firewood is the same. Firewood and logs from suppliers like Forestry Firewood are of exceptionally high quality, having been dried correctly.

This results in a much easier ignition and a hotter burn for the customer.

It can be perplexing when one load of wood produces plenty of heat while another fails to burn that hot. You might therefore believe that all firewood is the same?

However, nothing could be further from the truth: firewood varies massively in quality.

There are proven techniques that will improve the heat output of your logs. In this article we discuss why proper storage matters, look at the different species available, and explain why you should never burn wet wood.

 

What causes firewood to burn differently?

If you are scratching your head, wondering why firewood from different suppliers varies so much in heat output, let us explain.

 

Wood species

You may have heard logs described as a “solid fuel”. While they remain a natural product, they behave just like any other fuel. What is important to remember is that different species possess different energy densities, which is why a hardwood such as oak can burn far longer than a softwood like pine or spruce.

 

Moisture content

This is often the deciding factor between a roaring fire and a dull, unimpressive burn. Some suppliers do not dry their logs adequately. In the rush to fulfil autumn and winter orders, they may deliver wood that still carries a high moisture content. Wet logs burn poorly, give off excessive smoke and soot, and can damage both your stove and the chimney liner—never mind upsetting the neighbours.

 

How the wood is cut

Cutting logs into smaller pieces exposes more surface area, making them far easier to dry.

Large, chunky logs that have not been properly seasoned or kiln-dried tend to stay wet and create excessive soot when burnt. When seasoning your own firewood, cut it small logs and stack it so that air can circulate freely.

Tips for maximising the efficiency and heat output of your logs

With the current cost-of-living pressures, everyone wants better value from their firewood. The following guidance will help:

 

Invest in proper storage

Leaving logs on the grass and covering them with a tarpaulin is inadequate.

The wood will absorb ground moisture and the plastic sheet will trap it and then it will be absorbed by the logs.

A purpose-built log store keeps the wood off the ground and should incorporate slatted sides or gaps for constant airflow.
Stack the logs neatly, leave spaces between them, and ensure the roof overhangs enough to protect against driving rain. Position the store where wind can blow right through it.

 

Buy kiln-dried logs

Don’t settle for cheap yet damp firewood. Choose a company that provides bone-dry, kiln-dried firewood with a moisture content below 20 %. Such logs ignite quickly, burn hotter, and last longer because you’re not wasting energy evaporating water.

 

Use a moisture meter
A small handheld meter costs very little and tells you instantly whether a log is ready to burn.
Aim for 20 % moisture or less; anything higher should go back into storage to dry further.

 

Rotate your stock

First in, first out.
Burn the oldest, driest logs first and keep newer deliveries at the back of the store so they have time to season.
