Water heater installation cost by job.
Installed-labor pricing for Collierville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Collierville typically costs between $900 and $2,000 for a standard tank unit, and $2,000 to $5,000 or more for a tankless system. Most homes were built around 1996, so many existing units are nearing the end of their lifespan. Tennessee requires a permit for most water heater replacements, and the state follows the International Plumbing Code. With a humid subtropical climate and moderate winter inlet water temperatures, heat pump water heaters are a recommended choice for energy efficiency. The federal 25C tax credit offers 30% back (up to $2,000) for qualifying heat pump models, though Tennessee's HEAR rebate program has not yet launched.

Water Heater Installation in Collierville, explained.
What affects installation cost in Collierville
The final price depends on the unit type (standard tank vs. tankless vs. heat pump), fuel source (electric vs. gas), and any additional work like running a new gas line ($325–$1,100) or upgrading electrical. Permit fees and code requirements, such as an expansion tank on closed systems, also add to the cost. Labor rates reflect Collierville's high median income, and complex installations in newer homes with tight spaces may take longer.
Common water heater installation issues in Collierville
Permit requirements
Most water heater replacements in Collierville require a permit under Tennessee's adoption of the IPC. Like-for-like electric swaps may be exempt, but it's safer to pull a permit to avoid code violations.
Expansion tank on closed systems
Collierville homes with closed plumbing systems (e.g., check valves or pressure-reducing valves) must have an expansion tank installed to prevent pressure buildup, per code.
Aging homes and gas line upgrades
Many homes built in the mid-1990s may need a new gas line if switching from electric to gas, adding $325–$1,100 to the project.
What to expect during installation
A typical installation starts with the technician turning off power or gas and draining the old unit. They'll disconnect and remove it, then install the new water heater, ensuring code compliance (expansion tank if needed, seismic strapping not required in TN). After connecting water and power/gas, they'll test for leaks and proper operation. The job usually takes 2–4 hours for a standard tank replacement.
