Our Peacock Creek house has a long run to the far bathroom. How do we get hot water sooner with a Navien?

Recirculation. A Navien with ComfortFlow, or a pump with a dedicated return line, keeps hot water near the far taps. We set it to run on a schedule or on demand so it is not firing all day.

Clayton is on Contra Costa Water District water. How often should the Navien be flushed?

Start with once a year. We check the exchanger and the inlet screen at each flush, and if little scale comes out, the interval can stretch. If a lot comes out, we shorten it.

Can one Navien keep up with a big tub and two showers?

Only if it is sized for that flow and the gas line can feed it at full fire. For large houses, a bigger unit or a second one may be needed. We work it out from your fixtures and your gas supply.

Navien in Clayton

Navien heating and cooling in Clayton.

Clayton grew in stages: the 1970s expansion, Dana Hills and Clayton Wood in 1987, the homes built on the former Keller Ranch land in the 1990s, and the large houses of Peacock Creek from 1996. The bigger the house, the longer the pipe from the water heater to the farthest bathroom, and the more a Navien depends on recirculation and on a gas line sized for full fire.

Clayton is on Contra Costa Water District water, drawn from the Delta. Scale forms on any tankless exchanger over time, so we check it at every service rather than assume. A Navien NPE with ComfortFlow can bring hot water to the far taps sooner, but only when the recirculation is set up to match how the house is used. Our technician for Clayton works out of Benicia. The $99 diagnostic is credited toward the repair, and the quote is written.

Common repairs we handle.

Recirculation running nonstop and wearing the unit. A loop set to run around the clock fires the Navien far more than needed and wears the fan and igniter. We set a schedule or on-demand control that matches the household, and check the return line and the check valve.
Flame loss during a big draw. A large tub and two showers at once push a Navien to full fire. On a gas line that is too small, the flame drops out. We measure gas pressure at full fire and quote a larger line or a better setup.
Exchanger scale building between services. Delta water leaves minerals in the exchanger over time. Output drops and the temperature wanders. We descale through the service valves, clean the inlet filter, and note how much scale came out so the next interval fits.
