Replace your water heater in Goffstown 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.
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 Goffstown home.
Most Goffstown 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 Goffstown water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
Extend the life of your new water heater in Goffstown 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.

Our reputation is built on results. Here is what our customers have to say.
"Our 1970s galvanized pipes were failing one joint at a time. Got three bids on a whole-house repipe and these guys were competitive on price and had the best timeline. Seven days start to finish, minimal drywall damage, and water pressure is dramatically better throughout the house. Worth every dollar."
"Great job! Definitely recommend to others. Quick response, professional work, and fair pricing. Would use again without hesitation."
"Our main line backed up on a Saturday night and the Magnet Plumbing crew showed up within the hour. They cleared it, camera inspected it, and gave us a quote to fix the damaged section. Professional from start to finish."
