Lekto Woodfuels Night Briquettes - 20kg (20 Briquettes), Up to 8 Hour Slow Burn | Ideal for Wood Stoves, Log Burners, Sheltered Fire Pits & Chiminea | Compressed Wood Fire Bricks | Long Burning Logs

I followed the instructions and put the briquette on hot coals and gave it air to burn with flames and then once it had caught I closed down the air vents and the flames go out and it burns for 8 hours with the heat tapering off from about 6 hours. I have a garden office and struggled to keep an even temp. Using logs it would only be the correct temp for a little while and I would have to add logs and then it got too hot. This is the perfect solution. I use two logs to get the room warm and then the briquette to keep the temp even. It is smoky when you first put the briquette on but once it catches it settles. The photo is of the briquette just catching light after I put it on the hot coals from two logs.

These bricks do slow burn but only for 2 or 3 hours and in my experience you need at least two at a time. Quite good but a pungent odour from them when stored by the fire and quite a lot of ash.

These dont last 8 hours!!!! about 2 is more like it, very smokey, no flames, and low heat, I can touch my glass its not hot enough! What is the point?, certainly doesnt heat the room, doesnt look good as no flame, they are very expensive and a waste of time, having to buy 24 is not fair, they should do a "tester" pack of three, I am £30 short now and have 20 bricks i dont want!

Was a bit sceptical when I saw these but they do work. Keep room warmer overnight. Makes lighting fire following morning easier as the Stove is already warm and you will still have some glowing embers from the night before.

So we thought we would give these a try for overnight to keep the warmth being generated as opposed to coal. Well despite our best efforts we could not make them last more than 3hours, but more importantly the stove cooled down significantly on the thermometer we have for the fans, (which have made a big difference) to the point that the fans slowed down. They take a good flame to get them going, the resin comes off on your hands when handling them, and fthe ash generated is double what we normally see, so in our opinion and experience a complete waste of £32 !!

These may work in a home situation, but I can share that in an external setting i.e. tent stove camping they unfortunately do not, despite trying different techniques they are not effective, the most I got from them was about 90 mins before completely dying. They are too heavy to lug to camp if they are non-effective, I'm just going to use them as normal fuel now, its a shame as I really wanted them to work

These are brilliant. I got my box last week and the first time I tried them they only lasted between 2 and 3 hours. I gave them another go last night. I had a nice long fire in the evening so had a really good thick layer of embers. I out 2 of these in and for ten minutes I let them catch fire and really get lit. Then I shut the air off completely and this morning I came down 9 hours later to find the stove still warm. I broke the remains up then placed a log on their embers and 5 mins later fire was back again. Very very impressive.

Like the product - less impressed with delivery - ordered 17 Dec and due to arrive 20 Dec, later pushed back to 'before 26 Dec', then finally delivered 30 December - just left outside in a cardboard box in wet weather without ringing doorbell, fortunately briquettes still usable due to inner plastic wrapping. I use 2x briquettes in an inset 5.5kw wood burning stove, putting the briquettes on when there’s a good bed of glowing embers from earlier logs, I leave the vents open until the briquettes have caught and then shut down (as I would for logs). There is still a core of the briquettes glowing well after 8 hours and the room is noticeably still warmer than the rest of the house even 12 hours after putting briquettes on. They do produce a fair amount of ash so stove needs emptying more frequently.
