Cost to replace a Water Heater

At KC Water Heaters, we are committed to providing clear and upfront pricing as much as possible. Generally older homes built before 1960 can have additional code upgrades that can impact cost when dealing with gas water heaters. Our standard water heater replacement packages typically range from $1425 to $1725, which includes the unit itself, professional installation, and necessary materials such as pipes, fittings, and disposal of the old unit. There are also high efficiency units available for Heat Pump, Power Vent, and Tankless water heaters that have various price ranges. If switching from a gas to electric water heater there may also be electrical work that should be factored into the equation.

For a more detailed quote, please text or email a photo of the current water heater. Please include all of the venting.
