Gas water heaters require venting and a gas line, adding installation complexity. Electric units are simpler to install but may cost more to operate in areas with high electricity rates.
Power-vent and direct-vent units need PVC or stainless steel venting through a wall or roof, adding $300–$800 in materials and labor.
Draining and removing the old water heater adds $50–$150 to the job. Tank units are heavy (120+ lbs) and require careful handling.
Many codes now require a thermal expansion tank when replacing a water heater, adding $50–$150 for the tank and installation.
Western states, especially California, have among the highest labor rates in the country. Strict energy codes add requirements but also incentivize efficiency upgrades that save money long-term.

Most water heater installation projects in San Francisco take 1–1 day to complete.

Tank water heaters typically last 8–12 years, while tankless units can last 20+ years with proper maintenance. If your water heater is over 10 years old and showing signs of rust or reduced performance, it's time to plan a replacement.
