How We Calculate
We combine national equipment and labor cost data with your specific inputs (heater type, tank size, removal, venting/wiring upgrades) to generate a realistic range, not a false single number.

Estimates assume a standard residential installation in an accessible location, with mid-range equipment unless otherwise selected.
Accuracy & Limitations
Estimates are for planning purposes only and may vary based on your specific home, local labor rates and code requirements. Always get multiple local quotes.
Frequently Asked Questions
How long does a water heater last?
Most tank water heaters last 8-12 years, while tankless units can last 15-20 years with proper maintenance.
Is a tankless water heater worth the extra cost?
Tankless units cost more upfront but use less energy and last longer, which can offset the higher installation price over time.
Do I need a permit to replace a water heater?
Most jurisdictions require a permit for water heater replacement, especially for gas units. Your contractor can typically pull this for you.
Why would I need to upgrade venting or wiring?
Switching fuel types (e.g. electric to gas) or upgrading to a higher-capacity unit sometimes requires new venting, gas lines or a dedicated electrical circuit.
