Should I Choose Firewood Logs or Wood Briquettes?
Before we go any further, you'll need to decide whether to use firewood or briquettes are right for you.
Pros and Cons of Firewood Logs
If you're a complete beginner to wood fuels, your first instinct will be to gravitate to firewood. If you've ever camped or rented a log cabin, chances are you already know how to use this type of wood fuel.
The main pros of firewood logs are that they are easy to light, intuitive to use, and do not require your stove to be preheated before they can be added to the fire. All you need to get a firewood fire started are some firelighters, some kindling, and a lighter/match. The rest will happen on its own.
This being said, even the most premium firewood logs can't hold a candle to wood briquettes in terms of energy density, heat output, and burn time. Being less energy dense, a winter's worth of firewood will take up a lot more space in your wood store than an equivalent amount of briquettes. During the coldest days of the year, you'll need to add additional logs to your fire to combat the cold. And you'll have to regularly add new logs to the fire to keep the fire going.
This being said, firewood logs are still by far the most popular type of wood fuel in the UK.
KIln-Dried Firewood vs Seasoned Firewood
If you choose firewood, we recommend going the kiln-dried log route. There are many reasons for this. Being baked in an industrial oven for several days, this type of firewood has a lower moisture content than seasoned logs and is 100% safe to store indoors (compared to seasoned logs, which may become a home for insects, rodents, and mould). On average, kiln-dried firewood is about 10-15% more expensive than seasoned logs.

Hardwood vs Softwood Firewood
Due to their higher energy density, longer burn time, and lack of sap, hardwood logs are universally better than softwood logs. Unless you're really struggling and don't have access to hardwood firewood, we recommend steering away from softwood logs. The best hardwood logs in the UK are made from birch and oak, although alder and beech are also acceptable options.

Oak Logs vs Birch Logs
Both birch and oak logs make for great firewood. Birch is the more popular option. It is less expensive, easier to light, and burns with beautiful flames. Oak, on the other hand, is considered to be a more luxurious fuel. Thanks to its higher heat output and longer burn, it is the perfect fuel for cold nights. It is also often used by restaurants for cooking pizzas and searing steaks.

Pros and Cons of Wood Briquettes
More experienced users of wood heat tend to gravitate towards briquettes. This is because briquettes are a lot more cost-effective than traditional logs, albeit at the cost of requiring a certain amount of forethought.
Wood briquettes can run laps around firewood when it comes to energy density, heat output, and burn time. They require a lot less space to store, which makes them perfect for people who have limited storage space or don't have their own wood shed. They provide a lot more heat, so you'll need fewer of them to get the same heat output. And they burn longer, so you can focus on the things in life that truly matter, rather than stressing about your wood stove.
This being said, briquettes aren't perfect. In general, they're not as easy to light as traditional firewood. For example, Night Briquettes and Fire Logs should only be used in a preheated stove. Other fuels, such as Heat Logs and Nestro Softwood Logs, burn at such a high temperature that putting in too many of them at a time can crack the glass of your wood-burning stove, so you should only use them in accordance with the provided instructions.

Expert Recommendation: Use a Mix of Firewood and Briquettes
Our expert recommendation is to use a mix of logs and briquettes. Kiln-Dried Birch Logs are a perfect wood fuel for starting a fire. We recommend you use the top-down lighting method (see below) to light them. For ultimate lighting ease, we recommend using our Kiln-Dried Wood Kindling and our Natural Firelighters. Once your wood stove is pre-heated sufficiently, you can transition to your Sawdust Briquettes of Fire Logs. Use Night Briquettes during milder weather or when you want to economise. And use Hardwood Heat Logs or Nestro Softwood Logs when you feel that your main fuel needs a heat boost.
How to Start a Fire: The Top-Down Method
As decades of experience show, the top-down method is the best and easiest way to start a fire. Learning it takes just a few minutes. All you need to do is repeat these simple steps.
- Open your appliance's airflow controls. This will provide your fire with an adequate amount of air, which will help it grow faster.
- Place firewood at the lowest level. Place your firewood logs at the bottom of your log burner or wood stove. If your wood burner is big enough, you can build a second level of wood fuel on top of the first one. This will help you avoid having to add extra logs to the fire for longer.
- Stack your kindling on top of the logs. You can do so in a grid or pyramid shape. Make sure to leave a bit of space between the pieces to allow for proper airflow.
- Place a firelighter on top of the kindling. Place a Lekto Natural Firelighter on top of the kindling and set it on fire using a fireplace match or a fireplace lighter.
- Lower your airflow settings. When your logs are burning nicely, you can set your airflow controls to your preferred setting.
Wood Stove Maintenance 101
If you want your log burner to last you for many years, you'll need to maintain it properly. This isn't complicated, nor is it time-consuming. Here's everything you need to know about wood stove maintenance.
Wood Stove Maintenance 101: Avoid Burning Scrap Wood
First and foremost, never should you burn unseasoned firewood, driftwood, trash, treated wood, or scrap furniture in your stove. Doing so will not only hurt your appliance, but it will also release highly toxic chemicals into the air you and your loved ones breathe.
Wood Stove Maintenance 101: How to Clean Your Glass Door
Black soot can accumulate on the glass door of your wood stove if you throw in dense briquettes (e.g. Night Briquettes or Fire Logs) into a log burner that hasn't been sufficiently pre-heated. To clean the glass door of your stove, simply mix some of your leftover ash with water until you achieve a liquid paste consistency. Use this mixture and a paper towel to wipe off the soot.
Wood Stove Maintenance 101: Cleaning Your Stove and Flue
Why clean your wood stove? Whenever the natural moisture of wood comes into contact with flames, hundreds of chemicals are released, including creosote. Creosote is a toxic, cancerogenic substance that is hazardous to human health and its accumulation can result in a fire hazard.
To preserve your health and the health of your appliance, you need to clean your stove regularly. For the most part, this can be achieved with a cheap and cheeful £15 - £20 stove cleaning kit from Amazon.
Wood Stove Maintenance 101: How Often to Hire a Chimney Sweep?
If you're burning high quality, low moisture firewood logs and briquettes, then a yearly visit from a chimney sweep is more than enough to keep your chimney nice and healthy. If you burn low quality wood or improperly stored briquettes, you may need to hire a chimney sweep two to four times a year.
