Navien Tankless Water Heaters
Certified Navien installer and service technician. New installations and repairs throughout Southern California.
Why Go Tankless?
Endless Hot Water
A tankless unit heats water on demand. You never run out, no matter how many people are showering.
20+ Year Lifespan
A quality tankless unit with annual maintenance will outlast 2–3 tank water heaters. Long-term it wins on cost.
Energy Savings
You're not keeping 50 gallons hot 24/7. You heat only what you use — typically 20–30% more efficient than a tank unit.
The Navien NPE Series
We install and service Navien NPE condensing tankless units — the NPE-180A2, NPE-210A2, and NPE-240A2. These are the right choice for most Southern California homes: high efficiency, built-in recirculation, and reliable ignition in the variable temperatures we get in the IE.
Installation Requirements
Switching from a tank unit isn't always plug-and-play. Here's what may need to change:
Gas Line
Navien supports up to 25 ft on a 1/2" gas line. Beyond that, or in older homes with longer runs, a 3/4" line is required. We assess your existing setup during the quote visit and include any needed upsizing in the estimate.
Venting
2" PVC for a single unit. Multi-unit installations require larger pipe. Direct vent (two pipes) or power vent. Existing B-vent from a tank unit cannot be reused — new PVC runs required.
Condensate Drain
Condensing units produce acidic condensate that needs to drain. We run a line to the nearest floor drain, utility sink, or condensate pump.
Electrical
120V/60Hz required for the control board. Standard outlet near the installation location — not a dedicated circuit in most cases.
Water Quality (IE specific)
Inland Empire water is hard — high mineral content. We always recommend a pre-filter and annual descaling. Ignoring this shortens heat exchanger life significantly.
Annual Maintenance — Don't Skip It
IE water is hard. Calcium and magnesium deposit on the heat exchanger surfaces over time — this reduces efficiency, causes banging sounds, and eventually causes the heat exchangers to fail prematurely. Annual flushing with a descaling solution takes about an hour and protects a $2,000+ investment.
