What affects installation costs in Florence?
In Florence, the age of your home (median built 1980) may require updates to plumbing or electrical systems, increasing labor. Tankless installations cost more due to venting and gas line work. Permits are mandatory, and expansion tanks are required on closed systems, adding $50–$150. Local labor rates are moderate, but a like-for-like replacement is more affordable than converting fuel types. The federal 25C tax credit (30%, up to $2,000) can offset costs for qualifying heat pump water heaters.
