Navien in Palo Alto
Navien heating and cooling in Palo Alto.
Palo Alto mixes 1900s Craftsman and Tudor homes in the older north neighborhoods with mid-century Eichlers in the south part of town. The Eichlers are the interesting ones for tankless, because they have radiant slab heating and no attic, so a Navien serving domestic hot water has to be placed and vented carefully on an exterior wall or in a small mechanical space.
We service Navien condensing tankless throughout Palo Alto. The climate is mild and bay-moderated, so the units do not fight hard freezes, but the hard Peninsula water scales exchangers on the normal annual schedule. Most of my Palo Alto work is descaling, vent corrections on flat-roof Eichlers, and recirculation tuning in the larger older homes.
ADRIUM handles the combustion and gas side that quick installs skip. On an Eichler with no attic, vent routing is constrained, and I make sure the Navien intake and exhaust meet clearances on the exterior wall rather than being forced into a bad spot.
Common repairs we do
What we close on the truck.
- Flat-roof Eichler vent clearance problems. Eichlers have flat roofs and no attic, so terminations end up on a low wall or close to other openings. The Navien then recirculates exhaust and faults. I correct the termination location and clearances so intake and exhaust are separated and the unit draws clean air.
- Scale-driven flow and temperature drift. Hard Peninsula water scales the exchanger and the tap temperature starts drifting. I descale with a pump and solution and verify the flow sensor and mixing after, restoring steady output. I add isolation valves if the original install left them off.
- Ignition fault from a worn igniter or flame rod. After several years the Navien igniter or flame sensing rod gets fouled and the unit fails to light or drops out. I clean or replace the igniter and flame rod and verify the flame signal, rather than condemning the whole gas valve assembly.

FAQ
Navien in Palo Alto questions, answered.
-
Do you really drive to Palo Alto from San Ramon
We do. From San Ramon it is down 680 and across, same corridor as Mountain View and Los Altos. We service all of Palo Alto including the Eichler tracts. No travel fee on top of the work. -
Can a Navien work with my Eichler radiant heat
For domestic hot water, yes, and it can be placed to suit an Eichler. Tying a tankless into radiant slab heating is a separate question I answer in person, because Eichler radiant systems vary and I want to see yours before advising. -
How often should I descale on the Peninsula
Once a year for most Palo Alto homes. The water is hard enough that the heat exchanger benefits from an annual flush. With a softener I check the output and may tell you that you can stretch the interval.
