How much does it cost to replace a Rheem water heater?

The cost to replace a Rheem water heater varies widely based on the type, size, efficiency, and installation complexity, but you can expect a total installed cost range. For a standard 40 or 50 gallon Rheem gas or electric tank water heater, the unit itself costs 500 to 900 dollars for a 6-year warranty model and 800 to 1400 dollars for a 12-year Performance Platinum or Professional model. The Marathon series costs 1200 to 2000 dollars for the unit alone. Installation labor by a licensed plumber typically adds 400 to 900 dollars, which includes draining and removing the old heater, installing the new one, connecting water lines, gas line or electrical, venting, and disposal of the old unit. Permits may add 50 to 200 dollars. So total installed cost for a standard tank replacement is usually 1000 to 2000 dollars for a basic model and 1500 to 2800 dollars for a premium long-warranty model. For a Rheem tankless water heater, units cost 1000 to 2200 dollars and installation is more complex, often requiring new gas lines, venting, and electrical, so total installed cost is 2500 to 4500 dollars. Heat pump hybrid Rheem models cost 1500 to 2500 dollars for the unit and 2500 to 4000 dollars installed. Prices are higher in high-cost areas or for emergency same-day service.
