I like this idea.

I have been thinking about jkarp's tabletop system for a long time except that even though I often brew 2.5 gallon and 3 gallon batches when I am playing with recipes, I would prefer to be able to brew closer to 4 at a minimum for the house staples, and didn't really think it was feasible with my crappy 120V apartment setup, so I didn't pursue it much.

However, I think looking at your design, and with a well-insulated BK, maybe it is doable.

Confirmed. 5 gal is the max my kettle can boil at a roll I'm happy with. I do 3.5 gal batches (4.5 pre-boil) because they fit best into the Vittles Vaults I ferment in. 4 gal leaves very little headroom for krausen.

To achieve .5 gal / hr boil-off (absolute minimum I'd consider) requires 4K BTU or 1.2KW. This is JUST the energy to vaporize the water - not including kettle heat losses, etc. On my system, I consistently get .75 gal/hr boil-off which means 1.8KW of the element goes towards the boil and the balance of 200W is system heat loss.

Reason: Added maths.

I suppose if you wanted/needed 5 gal just brew a 1/5 bigger beer and top off in the fermenter. Whatever fits your needs/room/smiles.
Looking forward to your progress.

subscribed That simple brewery is sweet and simple. I enjoyed watching it come together. I can't wait to see the progress on yours.

Glad you decided to start new thread for it.

Any thoughts about making this a 1 pump, 1 vessel system?

I considered doing a single vessel, but I think the flexibility of two vessels is what I am after.

I'm in awe, you have an amazing design, and the Simple Brewery is sweeet! Because of you I have decided in the end to go all electric, with a HERMS system, I hope you think that replication is a form of flattery.

PROST to you sir! and Subscribed!

Nice!

I'm probably going to copy your design exactly. So please post a parts list when you're finished!

Okay, not exactly. I'll probably cut the RIMS and one pump.

My only question is about the lid on the boil kettle. With the chiller on there, it looks like you will have to keep the lid on. How are you going to get around sanitizing your chiller coil and keeping the lid off?
