Why Water Heater Installation Costs Vary in Arlington Heights
The age of your home (median 1973) can affect labor if old plumbing or gas lines need updates. Installing a tankless unit requires more complex venting and gas line work, raising costs. Adding a new gas line runs $325–$1,100. Permit fees and the need for an expansion tank on closed systems also add to the total. The federal 25C tax credit (30%, up to $2,000) applies to qualifying heat pump water heaters, but gas units remain the more affordable option locally.
