4000w at 240v can handle 16.7 amps. That's about right.
But if your main concern is the mash, I have several suggestions. First, 4000W is way more than you would need to stir your mash. Go with 2000W at 120. Secondly, I don't recommend stirring the mash with a heat stick. That's just my experience. I had a lot of hot pockets that way and it was not easy to control how much temps raise.
The better way to control mash temps is with RIMS or HERMS setup, which would require more parts than a heat stick, but I imagine that once you start down the round of shoving a heat stick in on the mash, a RIMS setup is not too far ahead.
Yeah, it's true I am opening a can of worms by using a heat stick. However, I am relatively happy at the moment with my setup and want to give electric brewing a kind of test run, while also saving some propane.
Ok, wow, I didn't expect the possibility of a 4000W element. That opens this up to more possibilities. I've seen other electric brewing posts that say they use x% of their element when boiling. Is that only controlled with a PID or is there a way to add a knob that can regulate the amps or watts going into the element?
As to stirring the mash with a heat stick. It seems others have done it and if the constantly stir, then they will be ok. What you say about hot spots, is something to consider, though. Maybe a 3000-3500W would be a compromise for that.
I am not sure I can go all electric as I see no way to do decoction mashes. So maybe a modified system in the future.
