Water Heater Replacement FAQ — Exeter, NH

Have questions about water heater replacement in Exeter, NH? Start here.

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

Replace your water heater in Exeter 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.

What size water heater do I need for my Exeter 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 Exeter home.

Do I need a permit to replace my water heater in Exeter, NH?

Most Exeter jurisdictions in NH require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for Exeter water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.

How much does water heater replacement cost in Exeter, NH?

Water heater replacement in Exeter 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.
