Water Heater Replacement FAQ — Dover, NH

What Dover homeowners want to know about water heater replacement — answered by our licensed plumbers.

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

Replace your water heater in Dover 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 much does water heater replacement cost in Dover, NH?

Water heater replacement in Dover 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.

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

Most Dover 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 Dover water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.

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

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 Dover 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.

"Magnet repiped our entire house last month. Clean install, finished a day ahead of schedule, and they respected our home the whole time. Worth every penny."

★★★★★

"Bought a new house and had a pre-purchase sewer camera inspection done. The plumber walked me through the footage and pointed out one section that would need attention in a few years. Honest assessment, no upsell pressure."

— Eric T.
★★★★★

"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."

— Frederick H.
