Water heater installation in Ferguson, Missouri typically costs between $600 and $1,400 for a standard tank unit, with tankless installations ranging from $1,400 to $3,500 or more. The median home in Ferguson was built around 1956, so many homes have older plumbing systems that may require updates during installation.
