Answers to frequently asked water heater replacement questions from Knoxville homeowners.
Replace your water heater in Knoxville when it is over 10 to 12 years old, produces rusty or discolored water indicating internal corrosion, leaks from the tank body, requires frequent repairs, or no longer meets your household hot water demand. A water heater approaching these conditions often fails unexpectedly — replacement before failure avoids an emergency.
Water heater replacement in Knoxville typically costs $800 to $1,800 for a standard tank unit including the heater and installation labor. Tankless water heater installation costs $1,500 to $3,500 depending on the unit and installation complexity. Magnet Plumbing provides free replacement estimates so you can make an informed decision about unit type and budget.
Tank water heaters cost less upfront and are simpler to install. Tankless units provide endless hot water on demand and typically have lower operating costs, but cost more initially. For most Knoxville families, a quality tank unit in the correct size is the most cost-effective choice. Our plumbers help you compare the total cost of ownership for your specific situation.
Extend the life of your new water heater in Knoxville by flushing the tank annually to remove sediment, replacing the anode rod every 3 to 5 years, setting the thermostat to 120°F to reduce mineral buildup and tank stress, and inspecting the T&P valve annually. Magnet Plumbing offers annual water heater maintenance service in Knoxville to keep your unit running efficiently.
