How much does a water heater replacement cost?

A like-for-like tank water heater runs about $1,200 to $3,500 installed, or $600 to $1,800 if you do it yourself. Tankless and heat pump models cost more but use less energy.

Can I replace a water heater myself?

An electric tank swap is doable for a handy homeowner. Gas units add venting and gas connections that are easy to get wrong, so many people hire those out.

How long does a water heater last?

A tank water heater typically lasts 8 to 12 years. If yours is leaking from the tank itself, it needs replacement, not repair.

Tankless costs more upfront and may need gas or electrical upgrades, but it saves space and energy and never runs out of hot water. Tank units are cheaper and simpler to install.

Do I need a permit to replace a water heater?

Many areas require a permit, especially for gas, to confirm safe venting and connections. Check locally before you start.

What drives the cost of Water Heater Replacement

Materials

The single biggest material variable is your product choice. Gas tank and Electric tank sit at opposite ends of the price spectrum, a decision that can shift your materials budget by 40–60%. Key line items include water heater, 50 gallon tank, flex connectors and fittings, sediment trap, vent, and gas pipe, each priced per unit and sensitive to regional supply-chain conditions. Bulk purchasing and timing your order outside peak season (spring and early summer) can reduce material costs by 10–15%.

Labor

BLS occupational wage data shows systems-trade crews earn $28–$52/hour depending on metro area, and most water heater replacement jobs require a two- to three-person crew for at least one full day. Labor typically accounts for 40–60% of the total project cost. Project complexity, custom details, tight access, or non-standard configurations, adds crew time and can push labor costs well above the national average.

Site conditions

Slope, soil type, and existing-structure condition are the three site factors contractors price most aggressively. Demolition or removal of old materials adds dumpster and disposal fees that rarely appear in online estimates. Local code requirements, permit fees, required inspections, and jurisdiction-specific material standards, can add $200–$1,500 to any project before a single tool is lifted.
