Groundchuck, out of curiosity, how do you heat the water for your HLT cooler, and how do you maintain the temp for sparging?
I use the boil kettle to handle all of the water heating tasks (Mash in, Sparge, and Boil). I have recently purchased a Chugger pump which makes the transfer of the water much easier (and more like a one man job). My brother and I always brew 10 gallons together so we end up with 5 gallons each. This also made lifting the water a much easier (two person) job.
Before I had the pump this was our process:
1) Bring Strike water to temp (+13 degrees) in the Boil Keggle
2) Place Keggle on middle tier and gravity feed into Mash tun (on the ground) for Mash In.
3) During the Mash, Bring Sparge water to temp (+8 degrees ..... ish) in Boil Keggle
4) Place Keggle back up on Middle Tier and Gravity feed into HLT (on the ground).
5) Lift HLT up to top tier, lift Mash Tun up to middle tier, then fly sparge into Boil Keggle on the burner.
6) Finally ...... Boil wort, add hops, etc. etc.
- This process requires no ladders to put hot water up in the top tier (which always sounds dicey to me but I know lots of people do it).
Now that I have the Chugger pump I leave the Boil Keggle on the burner and pump the heated water where I need it.
I have also recently purchased an
electric bucket heater which I am super duper excited to use. I plan to heat up the Strike Water directly in the Mash Tun a few hours before I start the brew so I can eliminate Step 1) in my process above.
As far as temp loss goes, the coolers only loose about 1 to 2 degrees per hour. So after you figure out how much you need to overshoot your Mash Temp, Sparge Temp, etc. (for me it's about 13 degrees), you'll be almost spot on every time. No worries.
I was considering another Blichmann burner and keggle for my HLT. However for much less cost ($110 for the pump vs $150 for the burner + $110 to make another keggle), I now have the other benefits that a pump can provide.
