Answers to frequently asked water heater replacement questions from St. John homeowners.
Replace your water heater in St. John 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.
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 St. John 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 St. John home.
Standard tank water heater replacement in St. John typically takes 2 to 3 hours including disconnection, removal, installation, and testing. Tankless water heater installation may take 3 to 5 hours depending on the venting and gas or electrical work required. Magnet Plumbing completes most water heater replacements in St. John in a single visit with same-day or next-day scheduling.
