This result is total B.S. Assuming the residential demand is the same for both options, the energy use for one or two tank-less systems should be identical. However, two tank water heaters would use more energy, due to additional standby losses.

While still not correct, try modeling one each domestic water heater 1, plus one each domestic water heater 2. This seems to provide a better result.
