I don't know how your utility works, but here it would be pretty expensive
to have two meters. If you upgrade you might want to look into combining
them. It will be expensive but maybe a good long term investment.

The water heater line on my bill usually runs between $10 and $20/month
[we're in SW Indiana], so it's pretty cheap. I'm going to start by
changing the bottom element and cleaning out the tank. I think it may
just have a short. If that doesn't work, I'll move on.

Thanks again, Toller.
