With your configuration does your cold water input go directly to the cold water input of your electric HWH?
I will leave myself open to yours and Stings set up. Boilermakers setup looked like a winner using the lower T-stat with incoming water being preheated by his sidearm setup. I was going to try that with the 110K once installed running the cold water source thru the 5GPM coil in the 110K on its way to the Rheem and having the lower T-Stat to sense/power on the cir. to charge the DHW tank until that lower T-Stat was satisfied at 120 deg. Using the lower T-Stat just seemed a very practical setup with his DHW plumbing configuration.
I have currently mounted http://www.grainger.com/Grainger/REDINGTON-AC-Quartz-Hour-Meter-3AB98?Pid=search
on both elements since the Rheem install. With six adults in the house slowing down the lower element hour meter is paramount. The usage meters will provide some feedback of the configuration.
I was going to leave the upper T-Stat/4.5Kw element in my Rheem powered on until I get some hands on with the 110K related to outfire. As I mentioned I’m waiting for a delivery date for the 110K so can’t speak from hands on. I’m passing along Boilermakers set up as a possible direction and I will try that configuration first. I will pass along an update once I get the 110K up and running.
Tom I hope you will post back what configuration you go with for your DHW generation and the results.
I’ll paste in a pic of Boilermakers setup so you don’t have to bounce back to the original post……Dick
