I can't recommend these wood fuels highly enough. My latest purchase was the oak chip blocks. They are a tad smaller than the other blocks and therefore more suited to my small stove. But goodness me, they kick out some heat! Admittedly the weather has warmed a fraction but I live in the furthest north west of Scotland on an island that sees an average of 10°c in the summer! And these wood blocks are just superb. They catch light easily with the help of a firefighter and they burn for well over an hour. I am seriously impressed. The other excellent point about Bioglow is their delivery. As stated, I live offshore, but they manage to deliver a half pallet or a full pallet to me within a week or so of ordering. Excellent company. Well done!
