In Fond du Lac, where the median home was built in 1967, water heater replacement is a common upgrade.

What affects your Fond du Lac water heater replacement cost
The age of your home (1960s average) may require updates to venting or gas lines, especially when switching to tankless. Winter inlet water temperature is very cold, which can reduce efficiency and increase operating costs. Permit fees and local labor rates also factor in. Choosing a more efficient heat pump unit qualifies for federal tax credits, but has a higher upfront cost. Tankless units cost more but offer longer life and energy savings.
