Water heater installation cost by job.
Installed-labor pricing for Ballwin, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Ballwin homeowners typically pay between $800 and $1,800 for a standard gas tank water heater installation, and $1,800 to $4,600+ for a tankless unit. With a median home age of about 50 years, many homes may need updates to gas lines or venting. Missouri requires a permit for water heater replacement, and work must be done by a state-licensed plumber. Because Ballwin uses the International Plumbing Code, an expansion tank is required if a check valve or backflow preventer is present. Cold winter inlet water means a properly sized unit is important for consistent hot water.
