Not sure of this going to plumbing or here, but anyways I want to put 2 electric water heaters in, both are 30 gal, 230V. My question is due to my service only being 100 AMP can I just run the bottom element on both and dc the top one. If so do I still leave both t-stats connected? The point being cutting both back on amp usage. 2 would draw 60 amp if they both fire up. I realize also this means the water will take longer to heat up, but I'm a patient guy. I am not rich so I can't write Bob Vila a blank check or pay thousands to an electrician for an upgrade. Thanks
