Only the HLT has a sight glass...why not the MLT or the Boil Kettle. I would think they would be useful there as well. For instance, on the Boil Kettle wouldn't it let you know when you've reach your target batch size during the boil, or that you're boiling off to rapidly or too slowly? And for the Mash Tun it would show where you're water level is during sparge for instance - or is there a risk of it clogging with grain in that function. The HLT looks like the least necessary unless you're working with a raised system multi-tier system.
Can someone explain the reasoning to me?
To me, HLT and BK have the most value add. HLT is important if you want to visually measure how much water you have drained to the MT for any water additions you make.
BK is useful to keep track of initial volume, boil-off, etc. Might be easily done with a stick or markings on your spoon or whatever, but a sightglass doesn't hurt any.
