Water heater replacement is one of the most common major plumbing expenses homeowners face, as most tank-style units last only 8–12 years. The national average for a new tank water heater installed is around $1,800, though costs range from $900 for a basic electric model to $3,500+ for a large gas unit with upgrades. Choosing the right size, fuel type, and efficiency rating ensures you get reliable hot water without overpaying.
Water heater size is measured in gallons and should be matched to your household's hot water demand. A 40-gallon tank is standard for 1–2 people, 50 gallons serves 3–4 people, and 75+ gallons is needed for households of 5 or more. Oversizing wastes energy heating water you don't use, while undersizing leads to frustrating cold showers during peak demand.
Gas and electric water heaters have different upfront costs, operating costs, and installation requirements. Gas units heat water faster and cost less to operate in most regions, but require a gas line and proper venting. Electric models are simpler to install and have no combustion venting needs, but carry higher monthly operating costs in areas where electricity is expensive. Heat pump (hybrid) electric models are the most energy-efficient option available.
A straightforward water heater replacement — same fuel type, same location, same size — is the least expensive installation. Costs increase when you switch from electric to gas (requiring a new gas line and venting), relocate the unit, or need to bring the installation up to current building code. Code upgrades often include an expansion tank, new shut-off valve, updated venting, or an upgraded drain pan.
Brand reputation and warranty coverage vary considerably in the water heater market. Rheem and A.O. Smith dominate the residential market and are sold through both plumbing supply houses and home improvement retailers. Bradford White is a plumber-preferred brand sold exclusively through professional channels. Longer warranty periods (10–12 years) typically indicate better build quality, including thicker anode rods and more durable heating elements.

Installation labor for a standard water heater replacement takes 2–4 hours and costs $300–$800 depending on complexity. A simple swap in the same location runs $300–$500, while jobs requiring new gas lines, venting modifications, or code upgrades run $500–$800+. Most plumbers include old unit removal and disposal in their installation price. Expect to add $200–$600 if code-required upgrades (expansion tank, drain pan, new shut-off valves) are needed.
A standard water heater replacement takes 2–4 hours. Conversions or relocations may take a full day.
Tank water heaters last 8–12 years on average. Factors that shorten lifespan include hard water (mineral buildup), high water pressure, and lack of maintenance. Flushing the tank annually and replacing the anode rod every 3–5 years can extend life to 15+ years.
Gas water heaters heat faster and cost less to operate in most U.S. markets, but require a gas line and proper venting. Electric models are cheaper to install and simpler to maintain. If energy efficiency is your priority, a heat pump (hybrid) electric model uses 60–70% less electricity than a standard electric unit.
For 1–2 people, a 30–40 gallon tank is sufficient. For 3–4 people, choose a 50-gallon tank. Households of 5+ should consider a 75-gallon tank or a tankless unit. Your first-hour rating (FHR) — the amount of hot water the unit can deliver in the first hour — is a more accurate sizing metric than gallon capacity alone.
Most jurisdictions require a plumbing permit for water heater replacement, especially for gas units. The permit ensures the installation meets safety codes for venting, gas connections, and seismic bracing. Permit fees typically run $50–$300. A licensed plumber usually handles the permitting process.
