Water heater installation cost by job.
Installed-labor pricing for West Haven, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In West Haven, CT, where the median home was built around 1960, water heater installation typically costs $800–$1,800 for a standard tank and $1,800–$4,600+ for tankless. The city's cold northern climate means winter inlet water is very cold, making heat pump water heaters a strong fit for efficiency. Connecticut requires a permit and licensed plumber for piping work; expansion tanks are mandatory on closed systems. Federal 25C tax credits (30%, up to $2,000) apply to qualifying heat pump units, helping offset installation costs.

Aging plumbing and gas lines
Many West Haven homes built in 1960 have galvanized pipes or undersized gas lines that must be replaced to meet current code.
Closed system expansion tank requirement
If your home has a backflow preventer, check valve, or pressure-reducing valve, an expansion tank is required by Connecticut code to prevent pressure buildup.
Permit and inspection delays
A permit is required for all water heater replacements, and the work must pass inspection, which can add time and require corrections.
What to expect during installation
A licensed plumber will first secure a permit from the city. The old unit is drained and removed, then the new water heater is installed with proper connections. For closed systems, an expansion tank is added. After installation, the plumber schedules an inspection to verify compliance with the Connecticut State Building Code. The job typically takes 4–8 hours.
