bio-bean Coffee Logs - Eco-Friendly Fire Logs for Wood Burners and Multi-Fuel Stoves (16 logs), Brown,24cm x 14cm x 22cm

I can break these into 4 smaller sections very easily, so they fit nicely into my shed's log burner (which is very small).I can't comment on a larger log burner, but they certainly seem to pump out a bit more heat than what I'd normally burn.The logs do give a bit of a coffee aroma, but nothing too profound when burning, but they smell great when you first open the bag (just like opening a jar of coffee).They due burn fairly slowly, so last a bit longer than other things I've used.The downside is that they can smoke quite a lot if they don't have something to keep them roaring, so I use kindling with these and the combination is great.I'm not sure I could use these just on their own, but as I say, I've not tried them in anything larger than my shed's burner.A bit disappointed that the price fluctuating so much during the colder months; as the Corona Virus Pandemic struck us all, some stores were still selling at the standard price, but eBay and Amazon seemed to increase prices by about 30%.I do respect that the coffee industry has gone quiet, so recycling the grinds hasn't been an option, but the coffee shops still aren't open and prices are coming down again, which suggests some profiteering. Stock is available now in most retailers at the original price.

Only had a chiminea for 2 months, tried store bought logs, had so much smoke I had to go inside just to not see yonder from smoke inhalation. Saw these logs on Amazon & oh my science were they a game changer. Put them on the burner, minimal to no smoke (depending on what I use to stoke the fire, though these logs created no smoke) extremely long burn and even then, when I think they're burnt out from the outside, I open them up with my firepoker and the way they're packed opens up creating intense (but not uncomfortable) lasting heat again. 100/10 would recommend, I've since bought twice as much as I did originally as they really do create a good effect with little to no smoke

I really like the idea of these logs: they seem to be properly carbon neutral and the whole thing has a beautiful hipster tang to it ("yeah. I only burn reclaimed logs made from coffee grounds. Yeah, probably only from Shoreditch cafes and the finest organic coffee grounds"). It's also super convenient to have them delivered next day to my doorstep via Prime, even though they're maybe a touch more expensive than my normal fuel.They definitely burn well - going up with a nice flame, thanks partly to their wax coating - and they certainly pack a pretty hefty thermal punch too.I do have a couple of reservations though: they seem to burn fairly quickly. Not loads quicker than an equivalent smokeless type log (compacted sawdust and the like), but certainly quicker than wood. They also seem to fall apart quite easily when burning, at which point they flare up and burn much quicker, releasing quite a lot of thick, acrid smoke (which I imagine my neighbours must love). I know they're not officially a smokeless fuel suitable for burning in a smokeless zone, but you'd like to think that something so eco is in the spirit, if not the actual letter, of that law. Releasing plumes of dense smoke probably isn't ideal from that point of view and I'd be interested to see if the manufacturers can get this stuff properly licensed for burning in those sorts of zones.Will I buy them again? Yes, I think I will and that must say something... but if you decide to buy them too, just don't expect them to be absolutely perfect. It is such a brilliant idea though, and I do get a worthy glow just from the eco-hipster cred I must surely be earning by burning these.

I fell in love with the idea of these as they encompass a couple if passions of mine; coffee and sustainability.The product its self is very good, produces a lot of heat and has a lovely aroma. However they do burn very quickly which is where is can become unaffordable for some (me!!) I went through an entire bag for the afternoon/evening.If money was no option for me I would definitely purchase these forever as they are not only a great idea, but also a great product.If you have money to burn (sorry, couldn't resist), buy these!! They are super and you won't regret it. If not, get them for a treat and to try them out. The aroma is warming and homely. I will purchase again, however it will be sparingly purely down to the cost.My star rating is purely reflective of cost not quality.

I am hopeless with the fire but my husband does it really well.He uses the kindling and one wooden log with the coffee logs. They seems to take a little long to catch alight. When they burn they kind of split so you wouldn’t be able to tell that they weren’t really logs. Until we got the hang of them they did smell a little but not overpowering or unpleasant. They also last a lot longer than would a give out more heat.

16 logs in the bag for 8quid delivered is great. They burn well, great heat, better than kiln dried logs. Just don't try to start the fire with them, best add them to an already well underway fire.***Update March 2023***I've consistently bought these logs as additional fuel to put into our inset stove. Again, not something to start a fire with but add them when the fire is out the way out and you have the air supply turned down low to get the most out of these logs

I took a gamble on these for a fire pit camping fire.Now if you do not keep the fire going hot. Like anything, it will smoke alot, however if you keep the fire going, we only used a few bits of kindling and eco fire starters. And the fire was roaring, quite impressed to be honest as I tried to cancel the order of these when I read the reviews others have had issue with fire pits,My advise is if can can keep a fire going u will have no problems.If you struggle to make fires it will go out and smoke.Happy camping.Oh and the logs smell lovely but not a coffee smell when burning, Unfortunetly.
