- On-demand operation at 6.6 GPM — no standby heat loss; unlimited hot water if demand is within flow-rate capacity
- Strong UEF 0.93 efficiency — approximately 20% lower annual operating cost vs 0.62 standard
- 12-year warranty — above-average protection; most competitors offer 6
- Requires dedicated 120K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
