Our San Jose Electric Water Heater Installation Process
SJWC + panel walk-through
We measure closet clearance, open the panel to verify breaker and wire gauge, read static pressure against SJWC / Great Oaks 6-10 gpg hardness, and photograph the data plate.
PG&E rate model + RE-series vs AeroTherm sizing
We pull recent PG&E bills (tiered $0.35-$0.48/kWh), model standard electric vs heat-pump 10-year cost, and right-size capacity for Almaden / Berryessa multi-bath households.
Install day — copper, seismic, expansion
Drain-down, removal, set, copper or PEX water connections, expansion tank, dual seismic straps, drip pan, 240V termination, and Eichler-friendly anode access.
SJ inspection + rebate filing
We meet the City of San Jose Building Division inspector on site, submit BayREN / PG&E rebate paperwork on AeroTherm jobs, and walk you through warranty registration.
What we do on the job
Every install follows the same checklist — no shortcuts on permits, expansion tank, or seismic.
- Verify Eichler / ranch panel capacity against nameplate amps
- Confirm 8/2 or 10/2 copper feed and conduit fill to SJ code
- Read static water pressure on SJWC / Great Oaks service before quoting expansion tank
- Pre-charge expansion tank to measured static psi (often 70-85 psi in 951xx ZIPs)
- Anchor two seismic straps to studs per City of San Jose checklist
- Pipe drip pan to interior approved drain per CPC
- Verify T&P discharge within 6 inches of pan or floor
- Install dielectric or properly bonded copper-to-galvanized connections
- Confirm disconnect within sight of unit per CEC + Building Division
- Submit BayREN / PG&E rebate paperwork same-day on hybrid jobs
San Jose Electric Installation Factors
Across Willow Glen, Almaden Valley, Rose Garden, Berryessa, Evergreen, and Cambrian, our electric installs hinge on four local realities: San Jose Water Company and Great Oaks Water delivers 6 to 10 grains per gallon hardness that shortens dip-tube and element life, PG&E (tiered $0.35 to $0.48/kWh) drives operating-cost math, City of San Jose Reach Codes and Title 24 amendments shapes which equipment is permittable, and 1970s Eichler and ranch panels with aluminum branch wiring dictate the electrical scope. We measure panel headroom, static pressure, and closet clearance on the same site visit before quoting.
- Panel capacity check on Eichler and ranch panels
- Static pressure read on San Jose Water Company and Great Oaks Water service
- Sediment-baseline flush before commissioning (6 to 10 grains per gallon)
- 30A vs 40A breaker sizing based on nameplate amps
- City of San Jose Building Division permit pull and inspection scheduling
- Expansion tank pre-charged to measured static psi
- Anode access planned for Willow Glen closet geometry
- BayREN and PG&E rebate paperwork for heat-pump-upgrade quotes
