Water Heater Installation services

The cost of water heater installation varies by job scope, access conditions, permit requirements, and local labor rates. A verified plumber provides a written estimate covering price, scope, and timeline before any work begins — no obligation.

A direct like-for-like tank replacement typically takes 2–4 hours: drain the old tank, disconnect supply and gas or electrical connections, remove the unit, position the new one, connect supply lines and T&P valve discharge pipe, reconnect gas or electrical, and commission. First-time installation in a new location adds rough-in time and may require a permit inspection before completion.

General guidelines by household size: 1–2 people: 30–40 gallon. 3–4 people: 40–50 gallon. 5+ people: 50–80 gallon. First-hour rating (FHR) on the EnergyGuide label is a more useful metric than raw tank size — it tells you how many gallons the heater delivers in the first hour from a cold start during peak demand. The matched plumber will size the unit for your household during the phone estimate.

Tank replacement is the right call when: budget is the primary driver ($1,200–$2,800 vs. $2,500–$5,500 for tankless), existing gas or electrical service isn’t sized for a tankless unit, or the household has modest and consistent hot-water demand. Tankless makes sense when: the home has a space-constrained mechanical room, multiple simultaneous showers regularly drain the tank, or IRA Section 25C tax credits (up to $600) improve the payback economics. See the tankless vs. tank comparison for a side-by-side breakdown.

In most jurisdictions, yes — especially for gas units. The permit triggers inspection of the gas connection, T&P valve discharge routing, and seismic strapping in earthquake zones. Some cities exempt direct like-for-like electric replacements. The plumber pulls the permit and schedules the inspection. Permit fees typically run $65–$200.

8–12 years is the industry standard lifespan, with hard water shortening that to 6–8 years. The anode rod inside the tank is the primary corrosion defense. Once it depletes, internal tank corrosion accelerates rapidly. A plumber can inspect and replace the rod for $150–$300, potentially extending tank life 3–5 years. If the tank is over 10 years old and showing symptoms — rust-colored hot water, rumbling noise, base leak — replacement is more cost-effective than continued repair.
