In Mukilteo, Washington, water heater installation costs typically range from $750 to $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless system. Adding a new gas line runs $275–$950. Local homes, with a median build year of 1991, often require updates to meet current codes, including seismic strapping and expansion tanks on closed systems.
