I have considered tankless and anyone that I talked with that had tankless - including a family of 6 (4 girls) were all quite happy with theirs. The caveate is that they all had Propane / Natural Gas. The one thing I have not seen specified here is whether or not the tankless systems being discussed are Electric or Gas? The scuttlebut down here is that no one with Electric is happy.
