Here's a picture of the inside of the bk and the screen i was talking about. Yeah thats rust, these kettles were assembled before stainless elements were available, so I'll have to swap those out.@Scout
Regarding the hop spider, I don't know what you mean by mesh screen? Do you have a mesh screen on your BK out valve perhaps or something else at the bottom? I just have a pickup tube on my BK out so I would put my hops either in a bag attached to the spoked spider or in the mesh hop spider. Something to keep hop bits out of the therminator is a good idea. I ended up preferring the mesh one because when I am done brewing, I pump PBW from the BK through the Therminator and HERMS coil and return it back to the BK through the hop spider. I back flush the Therminator separately first. It's a small amount really, hence "bits".
I had to assemble my panel. Im sure if I wanted to upgrade to 50a I could replace the yellow indicator lights with lighted switches and avoid drilling another hole.Ah that's a closer pic of the panel. Mine's a little more bare bones, just 2 PIDs and a boil controller, no timer, a multimeter instead of the amps and volts. The box is smaller. I bought it half finished, it was already laid out but I had to wire it. Couldn't tell you how involved it might be to upgrade it. Looking at their site however, the 30 and 50 amp panels are only slightly different in the second row. They add in a dial so that the power is on/off for the HLT and BK separately vs the dial for power to be one of off, HLT, or BK. That's a $400 difference on the pre-assembled 30 and 50 amp panels but only $100 on the DIYs. I guess drilling that extra hole really pisses them off! The box is the same size though.
Good point about circulating.Looks like you are ready to go and any little changes you can make as needed. I'll make this post even longer... Point is, the temp probe is on the outflow and can be grossly off if not recirculating.
You can't calibrate your MT temp directly to the HLT temp because there will be a temperature differential, your mash tun loses heat and the heat source is in the HLT. It's equipment driven. If you keep the room environment stable, once you know the differential, it may be relatively constant and you can account for that in your PID settings. This is another place where the instant read is useful, you can calibrate the MT PID and dial thermometer to it. My apologies in advance if you knew most of that.
I think Kal on his website says something about having the HLT warmer than the MT due to heat losses.
The last time I brewed was at my old house on a half ass single vessel electric system and I had so much water vapor it was condensing on the ceiling and dripping back down onto the counter, even though I had both garage doors and the window open. I understand how much it can build up without a fan.
