Common questions about water heater replacement in St. Johnsbury.
Replace your water heater in St. Johnsbury 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.
Water heater replacement in St. Johnsbury 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.
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 St. Johnsbury home.
Extend the life of your new water heater in St. Johnsbury 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.
