Water Heater Replacement FAQ — Durham, NH

Answers to frequently asked water heater replacement questions from Durham homeowners.

How do I know when to replace my water heater in Durham?

Replace your water heater in Durham 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.

How can I extend the life of my new water heater in Durham?

Extend the life of your new water heater in Durham 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 Durham to keep your unit running efficiently.

Should I get a tank or tankless water heater in Durham?

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 Durham 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.

What size water heater do I need for my Durham home?

For a tank water heater, the right size depends on the number of occupants: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, and 50 to 80 gallons for larger households. For tankless units, the required flow rate in GPM determines the correct unit size. Magnet Plumbing assesses your household demand and recommends the right unit for your Durham home.
