I bought some heatbeads this weekend, and I had a real problem with them. I filled my starter-chimney to the top, balled up some newspaper and lit it underneath. It burned out, I put more under and watched it burn away. Fast forward half an hour, I've burned half a newspaper and the fire still wasn't lit. It took me over an hour to get them to light. Eventually, 1.5-2 hours later, I had flames coming out the top of the chimney.
I dumped the coals on the smoker and put my meat on. The temperature fell and fell. Vents full open, it dropped to 180°F and stayed there for the first hour. Three hours later, I was drunk and grumpy, and the temperature had only risen to 210°F.
Four hours later, badly cooked meat taken off, the bloody coals start to get hot, and shot up to 300°F I closed the vents and the fire quickly died out. The next morning, I dusted off the unburned coals, and put them back in the bag. It was nearly full.
Question: Is this the sort of thing I should be expecting from heatbeads? If so, I can't see why you guys use them.
My first BBQ with guests ended up being the worst farce of a cookout I've ever done.
