Buying Guide: Key Purchase Considerations
- Hot water needs and space: Choose tankless for space efficiency or storage models for larger daily needs. Consider where it will be installed (RV, under-sink, apartment wall) and available space.
- Power requirements: Most units operate on 110V or standard household circuits. Check circuit capacity and whether multiple devices on the same circuit are safe to run.
- Flow rate and capacity: Tankless units are rated by GPM (gallons per minute). For showers, you typically want at least 1.5–2.0 GPM. Storage models depend on tank size (e.g., 10–12 gallons) and recovery rate.
- Safety features: Look for IPX4 waterproofing, dry-boil protection, leakage protection, automatic power-off, and temperature controls to prevent scalding.
- Installation and compatibility: Consider required clearances, venting (for propane or gas models), and whether the unit is designed for under-sink or RV installations. Verify warranty terms and service availability in your region.
