Every other plumber tells you they "work on all brands." We only install three: Navien, Rinnai, and Rheem. These are the brands with parts availability, proven reliability, and warranty support worth putting in your home for 20 years.
The reliability benchmark. Simpler to service than Navien, with exceptional heat exchanger longevity. The RX series is our pick for homeowners who want "set and forget" for two decades.
Best-value tankless with the strongest US parts network. The Prestige line matches Navien and Rinnai on efficiency with slightly lower upfront cost. Ideal for budget-conscious homeowners.
When homeowners ask us "which should I pick," the honest answer is "it depends." Here's the comparison data we use at consults.
We don't play favorites — we pick based on your specific situation. Here's how we think about the match.
4+ bathrooms, want instant hot water at every tap, like best-in-class Wi-Fi diagnostics, and don't want to pay extra for recirculation. The NPE-240A2 is our most-installed unit in Potomac and Bethesda.
You want the simplest unit to service, you plan to be in your home 15+ years, and you don't mind paying for recirculation separately. The RX160iN is our most-specified unit in Gaithersburg and Germantown.
2-3 bathrooms, single-story home, just need reliable hot water without premium features. The Prestige RTGH series saves $300-500 vs. comparable Navien/Rinnai models with only modest tradeoffs.
