Why Fresno Homeowners Are Switching to Navien Tankless Water Heaters

Navien is the #1 selling condensing tankless water heater brand in North America — and in Fresno, we install more Navien units than any other brand. After completing Navien's Service Specialist certification, our team has a deep understanding of what makes these units exceptional and where they perform best. Here's an honest look at why so many Fresno homeowners are making the switch.

Built for Efficiency — Especially Here

Navien's NPE-A2 series achieves up to 0.97 UEF (Uniform Energy Factor) — among the highest efficiency ratings available for residential water heaters. In practical terms, that means almost no energy is wasted. Fresno's natural gas rates make this especially valuable. Homeowners switching from a standard tank unit to a Navien typically report gas bill reductions of $20–$50 per month, depending on household size.

The condensing design is key. Traditional tankless units exhaust hot gases and lose that energy. Navien's condensing heat exchanger captures that exhaust heat and uses it to pre-heat incoming cold water — extracting every BTU possible from the gas you're paying for.

NaviLink: Remote Control From Your Phone

Every NPE-A2 series unit is Wi-Fi ready. The NaviLink app lets you control water temperature, monitor energy usage, set schedules, and receive maintenance alerts from anywhere. For families with varying schedules — or rental property owners who want remote control — this is a meaningful feature no traditional tank can match.

ComfortFlow: Hot Water at the Tap, Fast

One of the common complaints about early tankless units was a "cold water sandwich" — a burst of cold water before hot arrived. Navien solved this with their built-in recirculation pump and buffer tank (ComfortFlow technology). Hot water reaches your faucet in seconds, not minutes. This is especially noticeable in larger Fresno homes where the water heater may be far from the master bath.

20+ Year Lifespan

The average traditional tank water heater lasts 8–12 years before rust, corrosion, or sediment buildup forces a replacement. A Navien unit maintained with annual descaling — important given Fresno's hard water — routinely lasts 20 years or more. The stainless steel heat exchanger resists corrosion far better than the glass-lined tanks in traditional units.

Industry-Leading Warranty

• 15 years on the heat exchanger
• 5 years on parts
• 1 year on labor (when installed by a certified specialist like Stedman's)

That heat exchanger warranty is one of the longest in the industry. It's Navien's confidence in their own product — and it should give you confidence too.

Is Navien Right for Your Home?

Navien tankless units require a 3/4" gas line and proper venting. Some older Fresno homes with 1/2" gas lines need an upgrade before installation — we'll assess this during your free consultation. For homes with electric-only service, we recommend A.O. Smith's hybrid heat pump water heater instead, which is also highly efficient.

The NPE-180A2 handles most families of 2–4 comfortably. The NPE-240A2 is ideal for larger households with higher simultaneous demand. We stock both and can typically install same-day or next-day.
