What’s different about water heater replacement in San Jose
Seismic strapping
Code-compliant strapping is required on replacements.
Hard water scale
Scale shortens tank life and requires tankless descaling.
Permits
Replacements generally require permits and inspection.
Combined hydronic systems
Some Eichler and older homes use a water heater or boiler for radiant heat, which changes sizing and replacement options.
Homeowner checklist
