Kiln Dried Logs Q & A

Q: What are Kiln Dried Logs?

A: Kiln Dried Logs are logs which have been artificially dried in a kiln down to to a moisture content of 10-15%. The purpose is for them to burn hotter with a higher longer lasting energy and less residual moisture. There is also the added purpose of minimal stove and flue problems which poorly seasoned/wet logs create.

Q: Does the government ban on the sale of wet wood apply with Kiln Dried Logs?


A: No, the government ban on the sale of firewood above 20% moisture in quantities smaller than two cubic metres won't apply with Kiln Dried Logs as they are Woodsure Ready to Burn approved. The reason why this ban has been implemented is to combat air pollution.

Q. Why should I buy Kiln Dried Logs?

A. The reason for kiln drying is to improve the overall quality of the wood, providing you with the best possible quality every time. The moisture content will be an average of below 20% which is what the stove manufacturers recommend. This provides a clean burn with maximum heat output of 4-5kWh per kg, once you've established a solid base you can lower the oxygen intake for a slower longer lasting burn. You are likely to use up at least twice as much seasoned firewood for a similar heat output. The super dry, high energy hardwood logs will provide you with a clean burn and will reduce sooting of the stove glass and reduce soot and tar accumulating in the chimney flue. The kilns are fired on wood waste which is very eco-friendly.

Q: Are your Kiln Dried Logs hardwood or softwood?

A: Our Kiln Dried Logs are a mixture of ash, beech and oak hardwood. Hardwood is the wood chosen because they are denser - they burn with higher energy and last longer than softwood logs. However, kiln dried softwood logs are easier to light and burn brighter.

Q: Why are Kiln Dried Logs better than seasoned logs?

A: A decent sized batch of oak logs can take as long as three years to naturally season before they are suitable for burning. With Kiln Dried Logs they are dried in a large kiln to ensure low moisture and are ready to burn straight away.

Q: Where are your Kiln Dried Logs from?

A: Our wood is sourced from estates local to Certainly Wood which is based in Herefordshire. Our wood is sourced only from trees that are felled as part of the natural thinning process by well managed forestry. The removal of these trees provides more light for the remaining trees to grow efficiently.

Q: How are Kiln Dried Logs seasoned and processed?


A: Trees are harvested and left in the woods in long lengths for a few months before being delivered for processing at a sawmill. The wood is then cut into small logs and are then placed into bins for as much air drying as possible before going into the kilns.

Q. What size are your logs?

A. The standard size is 25cm (9.75 inches.) The diameter range is 5-15cm (2-6 inches.)

We can also supply 35cm or 45cm size logs (subject to availability) for delivery in bulk bags.

Q. How much does your wood weigh?

A. You should always buy wood by volume and not weight as the wetter it is the heavier it will be. An equivalent amount of kiln dried wood is likely to produce twice as much heat as poorly seasoned wood, therefore kiln dried wood represents far better value for money.

Q. When is the best time to buy firewood?

A. Kiln dried firewood is ready for immediate burning, this can be bought at any time of the year. Seasoned wood is best bought during the summer months and even then will almost definitely need to be left for a further period of time to dry. Look out for the Ready to Burn logo.

Q. How much firewood will I need to buy?

A. This will vary greatly and depend on a number of factors -

- The size of your property and how well insulated it is.
- The efficiency of your stove, how you use it and how often you use it.
- The weather.

In an average year you are likely to use 3-4 cubic metres of kiln dried firewood. You will use significantly more seasoned firewood to achieve the same heat output.

Q: How should I store my Kiln Dried Logs?

A: The ideal place to store your Kiln Dried Logs is in a dry and airy environment. You could stack inside your garage, shed or greenhouse as long as they are not affected by condensation. AVOID damp storage areas which lacks air movement! If none of these mentioned options are available to you then you may wish to invest in a wood store to help protect them from the rain, preferably one with vented sides. Alternatively, you could store them off the ground (ie on a pallet) and shelter them underneath a waterproof tarpaulin.

Q: Could I just leave my Kiln Dried Logs inside the bulk bag?

A: We don't recommend this outside, as the bulk bags are showerproof not waterproof. If you have no other choice and don't want to invest in a wood store then you could shelter underneath a waterproof tarpaulin. Bulk bags stored inside a garage is fine, but we recommend you stack your logs in a dry environment in order for your logs to recieve sufficient air flow.

Q: What if my Kiln Dried Logs get wet?

A: Don't worry if they get a bit wet, give them a few days to air. You are likely to need to get a solid fire base going first, but they will definitely burn well enough on a fire that is already hot enough. Kiln Dried Logs are sealed to the core to prevent further moisture from getting inside, so are likely to remain dry internally as long as they don't get saturated!

Q: What about exported kiln dried log crates? Are they any good?

A: The firewood exported from the likes of Latvia and Lithuania are of reasonable quality. However, their wood is likely to come from an excessive cull of natural woodland and they are also likely to skip the seasoning process. Once their trees are felled their logs are cut and kiln dried immediately and packed in open crates to simplify their logistics. This process produces firewood with a moisture content similar to well seasoned logs but is marketed and sold at a premium. Their wood is likely to be birch wood, meaning it could burn up to 30% faster than our Kiln Dried Logs. Furthermore, there is the risk of bringing harmful tree pests and diseases into the UK, hence the importance of the Grown in Britain and Ready to Burn logos.

In order to ensure that the demand of sustained British firewood doesn't exceed supply and doesn't lose out to exported goods our suppliers at Certainly Wood encourage donation towards tree plantation to help enhance British forest sustainability. We firmly believe in supporting both the local and the British economy following the impact of Covid-19 so let's help play a part! You have the option to add plant a tree to your order.

Q: My fire is burning quicker than usual! Why is this?

A: Don't forget to close your air vent (and damper located within the stovepipe if you have one) once you've got your fire going! It is also not unusual for fires to burn quicker than usual on a windy day when the wind can get inside vents. If you're burning softwood logs, they burn faster than denser hardwood logs. Other more serious reasons could be damage to the stove such as a failed gasket seal on the stove door or a possible leak in the stovepipe area.

Q: How often should I get my chimney swept?

A: In order to keep the risk of a chimney fire and carbon monoxide poisining down to a minimum we advise you to get your chimney swept at least once a year. If you burn seasoned firewood on a regular basis then it is recommended that you have your chimney swept at least twice a year. It is advised that you have your chimney swept up to four times a year if you are constantly burning poorly seasoned wood, which goes to show that whilst poorly seasoned wood is cheaper, it is a false economy! Your chimney sweep merchant can pass on useful advice when necessary. An annual stove maintenance check every summer is advised too.

Q: How can I tell if my firewood is seasoned?


A: This is something you won't need to worry about with our Kiln Dried Logs! If you are looking to season your own firewood, a dry and airy shelter with vented sides like the one pictured above or a wood store are ideal for storage. You will want at least six months of seasoning time for softwood logs and for finer cuts of oak hardwood you will want to allow around three years of seasoning time. When it is time to test their edibility, a good indicator is to bang two pieces of wood together. If the wood is seasoned it will give a hollow sound on impact whereas unseasoned wood will give a dull thud! If you're unsure, check the logs for deep cracks running through the grain and a darker look - if they posess these then they should burn fine. On the other hand, unseasoned wood will look brighter and still have a fresh sap smell. For convenience you could invest in an inexpensive wood moisture meter for an instant reading, test all sides of the log. If you get a consistent reading of below 20% you are good to go!

Q: Are there potential dangers from burning wet/poorly seasoned wood?

A: Yes, this can cause some serious tarring problems with the chimney and corrosion problems with the inner liner of the flue. Cue to the risk of carbon monoxide poisoning and chimney fires if not swept reguarly, another reason to consider our Kiln Dried Logs.

Q: How will my order be delivered?

A: Your order will be delivered in a dropside tipper, as long as there is adequate access we will be able to leave your bulk bag wherever you like. We will stack smaller bags where required. We will offload your bulk bag so that it slides down slowly and lands standing up, but we will make sure there is adequate clearance both above and below! If you are going to offload a bulk bag, why not do it in some style? Other suppliers of Kiln Dried Logs are likely to need adequate clearance for a 7.5 tonne vehicle.

Q: Are you able to tip/move my bulk bag straight into my garage?

A: Yes, as long as there is adequate clearance both en route to your garage door and the height of your garage door itself. This process has been a big hit with our existing customers! Our 1.2m3 bulk bags are our best sellers due to us being able to physically move the bag further inside your garage to enable clearance to close your garage door. A 1.6m3 bulk bag represents better value for money, but due to their height are trickier to physically move! Should you require your 1.6m3 bulk bag to be physically moved further inside then please ensure further help is at hand!

Q: Can you help me empty my bulk bag?

A: This is out of question in winter time! However, during the summer time when demand is off-peak we can assist with emptying your bulk bag for an agreed price.

Q: How do I pay? Is my payment secure?

A: We offer online payments through Paypal or online card payments through Cubecart which are 100% secure - we will be in contact to arrange delivery shortly after your online order. If you would rather pay via bank transfer then please contact us via e-mail or phone with your order so we can e-mail your invoice to you, our bank details will be on the bottom of the invoice - we will then arrange delivery as soon as payment has been recieved. Alternatively, you may pay over the phone with your card details and arrange delivery - once your card payment has been processed successfully we will destroy your card details immediately. For more detailed information please view the GDPR Privacy Policy.

Q: My online order is not being accepted! Why is this?

A: Our online shopping system is dependant on postcode areas in relation to how close they are to our yard - so this goes by the postcode area you live in and the order quantity. The closer your postcode area is based to our yard, the smaller the minimum order requirement will be. However, one bulk bag qualifies for Areas 1-3

Some of the postcode areas can be very diverse! A prime example is Hingham (11 miles away) is in the same postcode (NR9) as Lenwade (29 miles away!) Check out Delivery Locations at a Glance for more details to see if your location can qualify for a better minimum order or to see if your location in the boundaries of an outer postcode area is within our range.

Q: I've forgotten my password and I can't access my account! What do I do?


A: You can request a password recovery which will automatically e-mail you with a link (you may need to check your junk folder.) Follow the link, enter your new password twice and you should be good to go. If this doesn't work then please contact us with your name and address and we'll reassign you with a different password. Once you're logged in with your reassigned password, click on My Account and you'll be able to choose a new password.

Q: Can I pick and choose my delivery date and time?

A: During off-peak times this will be easier to arrange, we can advise whether your order will arrive in AM and PM though we cannot offer a precise time. During peak winter times we will look to stick to our weekly route plan in order to fit in as many orders as possible, though we've kept Fridays and Saturdays free to offer some flexibility.

Q: Do I need to be at home when you deliver?

A: As long as we have access to your shed or the area you would like your small bags stacked/bulk bag offloaded, you do not need to be at home.

Q. How long will I have to wait for a delivery?

A: Generally within three days, sometimes sooner. We have a weekly route plan written up in order to fit in as many deliveries together as possible. December in the build up to Christmas time can get very busy when delivery times are likely to double! 'Beast from the East' scenarios are even more hectic! Road conditions are likely to add unpredictability so please take these into consideration when ordering. Please view the Direct Deliveries Terms & Conditions.

Q: I need my logs sooner! What are my options?

A: You may arrange a yard collection by prior arrangement. Please contact us to arrange this so that we can make sure one of us are present at the yard when you arrive.
