What affects installation costs in Henderson?
The age of your home (median built 1972) can increase labor if old connections or venting need updating. Adding a new gas line for a tankless unit runs $250–$800. Permit fees and code compliance (expansion tank on closed systems) add to the total. Choosing a tankless model raises the price due to higher unit cost and more complex installation. The federal 25C tax credit offers 30% back (up to $2,000) for qualifying heat pump water heaters, which can offset costs.
