Buying Guide: Key Considerations For Selecting A Tank Water Heater
- Space and installation: Measure available space and check whether a vertical wall mount or under-sink setup fits your layout.
- Capacity needs: Choose a size that matches your daily hot-water demand. More outlets and simultaneous uses require larger tanks.
- Heat retention: Look for good insulation (foam thickness) to minimize standby heat loss and keep energy costs lower.
- Safety features: Prioritize units with dry-heating protection, overpressure safeguards, and IPX rating for moisture exposure.
- Electrical requirements: Verify voltage and circuit capacity (most listed are 120V); ensure your electrical panel can support the unit.
- Durability: Enamel or glass-lined interiors resist corrosion and extend service life in typical residential settings.
- Maintenance: Consider ease of access for drain valves, inspection, and periodic flushing to extend life.
