Answers to frequently asked water heater replacement questions from Fremont homeowners.
Replace your water heater in Fremont 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.
Most Fremont 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 Fremont water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
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 Fremont 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.
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 Fremont home.
Our reputation is built on results. Here is what our customers have to say.
"Needed a gas line run to a new outdoor kitchen. Magnet did the install, passed inspection first try, and communicated every step of the way. Solid, professional company."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
"Hydro jetted our main line after years of slow drains. Huge difference — everything drains fast now. Well worth it."
