Two elements one PID?

Yeah, that's more than enough with 5500. At 120 though it looked like he only got about 30 degreed rise. Which if I start with hot water at about 120, that would still leave me with only 150. Though... when he is using the same 5500 with only 120 he realistically has a 1375w which is 1125w less, or almost half if going with a 2500w element. I am not sure if it's linear, but if it holds close to true, then you would get some here near 60 degrees rise with the actual 2500w element at 120. Starting at 120 degrees hot tap water you could theoretically get to 180 which is more than enough to sparge with. This is all predicated on actually being able to run the 2500w element on a 30a 120v circuit.

Theres plenty of 240v cartridge heater options in the 2500w range too... Ive never tried using my 1800w rims to heat sparge water but I recently started using it to take my recirculating mash from mash temps to mashout 168 and it takes about 10-15 mins or so to take my mash for an 11 gallon brew session from 150 to 168 at 1.5gpm flowrate (and thats with an extra 3 gallons of liquid under the false bottom) so I dont think even a 1350w rims would have too much trouble heating sparge water on the fly depending on how quickly one sparged and how long the element was for longer contact time.... I recently slowed my sparge flow rate way down from basically rinsing over 10 mins in a fly sparge to sparging over a 30-40 minute period (20% speed on my pwm controlled pumps) and my efficiencies went from 86% average to over 91% for my last three brew sessions since. my last beer brewed on new years day netted me 92.7%
