Flat side. Holds tighter around the fermenter without sliding around.Feldon said:For those who wrap their heat belts around the fermentor, do you put the ribbed side against it or the flat side, or doesn't it matter?
No expert, but i imagine it potentially could be. As i understand it, the fermentation vessel being heated is supposed to work as a heat sink. The belt should be in contact with the vessel below the liquid line so that heat can disperse properly. A hot belt operating for any extended period without the heat sink would then potentially be dangerous, especially if overlapping.MetalDan said:The belt is too large so I wrap it around the bottles twice and the cord overlaps, might this be a fire issue?
While it might not cause a fire, assuming that these belts don't generate enough heat to start cardboard or towels smouldering, the belt itself may not last very long as there's no liquid to dissipate the heat being generated. Not long after I first started brewing I forgot to unplug the heat belt and only realised a couple of weeks later - end result was that the plastic coating around the wiring dried out and disintegrated. Didn't trip the safety switch, YMMVHaving just bottled my first batch I have wrapped my heat belt around a empty slab carton filled with my brew bottles. This is also insulated with towels, with my temp controller keeping it around 20. Is this necessary or just dangerous? Temp I imagine will drop down below 10 degrees over night and read I am meant to keep my bottles at closer to 20 for 2 weeks?
