Key Features to Look for

When shopping for an 80 gallon electric water heater, keep an eye out for these essential features:

  1. First Hour Rating (FHR): This measures how much hot water the heater can produce in an hour and is crucial for understanding if a model meets your peak hour demand.
  2. Energy Factor (EF): Higher EF numbers indicate a more efficient water heater, which translates into lower energy bills.
  3. Durability Enhancements: Look for models with corrosion-resistant tanks and glass-lined interiors to extend the lifespan of your unit.
  4. Warranty: A longer warranty period is often an indicator of a quality product.

Installation Insights

Proper installation is crucial to the efficiency and longevity of your 80 gallon electric water heater. Here are some tips:

  • Location: Choose a space that supports the weight of a fully filled tank and allows for easy maintenance access.
  • Electrical Requirements: Ensure your electrical system meets the amperage and voltage requirements of the unit.
  • Plumbing Connections: Use high-quality materials and follow local codes for water and pressure relief connections.

Maintenance Must-Dos

Regular maintenance keeps your water heater running efficiently and can prevent costly repairs. Include these tasks in your routine:

  • Annual Inspections: Check for leaks, sediment build-up, and component wear.
  • Temperature Settings: Adjusting the thermostat to an optimal setting (usually around 120°F) can reduce energy consumption and enhance safety.
  • Drain and Flush the Tank: Performing this task yearly can prevent sediment from impairing tank efficiency and longevity.
