I currently have a 50 gallon water tank in my house and I want to replace it with a tankless system. The primary reason to replace it is space.
I recently installed 2 HeatWorks Model 1 units to test them out (I left the tank in, luckily), but that failed miserably for reasons not germane to this question. I'm returning those and now I'm left with 3 separate 30A electrical lines, including the one the tank is currently using.
I would like the heater to be able to produce enough hot water for 2 simultaneous showers. I've seen that the units that can handle that tend to demand 60-70Amps. It's not easy to run new electrical to the place where the water is, so my question is whether a unit exists that takes multiple electrical lines. This would allow me to use the 2 or all 3 30A lines.

Yes, most larger "whole-house" units require two or even three circuits. Problem is most of those require two or three 40, 50 or even 60 amp circuits.
You will have to do some research to find one that will supply your needs but only requires three 30A circuits. I will say, don't get your hopes up.
