Buying Guide: Key Considerations for a 68-Gallon or Larger Unit
- Capacity versus demand: Match the tank size and recovery rate to your household hot-water usage, including multiple showers, laundry, and dishwashing.
- Energy source: Electric, hybrid, and propane options have different operating costs and installation requirements. Consider climate, electricity rates, and venting needs for gas models.
