"We have just ordered our second lot of logs. They give good heat, are easy to use. They burn for a decent amount of time and leave little ash. One hint is break them in half because they expand length ways when burning so can end up against the stove door when burning. A great alternative to logs"

"Lava Logs are the best ever. They are super dry, well packed. They give amazing burn time and heat output. Vertical burning technique is the key."
— Clive W. (5/5)
"Was dubious at first to how good these would be, so after buying a small trial pack before committing to a big purchase, we were really impressed with the heat these gave and also how long they lasted. The added bonus to lava logs is how little ash is left when they have burnt down. Fair to say we ordered a full pallet and am very happy with the purchase."

"We've used various briquettes over the years but the Lava Logs are the best we've used so far. They perform really well and are easier to handle than most others. Good price and excellent customer service too. We had an issue with the delivery company, only a minor one really and nothing to do with Duffield Timber but Lewis at Duffield went above and beyond to sort it out for us. Excellent all round and will certainly be buying Lava Logs again."

"Having tried and tested many types of firewood over the years, from Kiln Dried Hardwood through to Heat Logs and everything in between, I am very impressed with the Lava Logs from Duffield Timber and will solely be using them for all my firewood needs going forward. Lava Logs are easy to light and burn for a long time, chucking out an awesome amount of heat. They are also very easy to break into smaller more convenient pieces. I simply take a log in each hand and bang them together in a criss-cross shape. Voila! 4 pieces of Lava Logs! Lava Logs are the only logs you'll ever need!"

"Brilliant heat logs. Kept informed on delivery which was on time as stated. Logs on delivery toppled off pallet not the delivery drivers fault just unfortunate no damage and no one hurt - Delivery driver was excellent very pleasant and helpful. Received a phone call from Duffield timber a few hours after delivery they were aware pallet had toppled and rang to ensure I was ok and product was acceptable. Excellent service obviously care about their customers. Thank you."

"I have recently placed my second order of the lava logs. They are the best, long burn and very hot too. I received my last order recently and made a saving for next Winter! I bought a half pallett and worked out to be £3. 85 per 6 pack! Much cheaper than i have bought from local shops. Customer service is fantastic too. Will reccommend to anyone 😊"

"Outstanding product, lights promptly and produces a high level of heat when only using half a log. Ideal for us we only have a small 5 KW stove. Burns extremely efficiently with minimal soot on the glass and fire bricks and low levels of ash. Will be ordering again shortly."
