Buying Guide: Key Purchase Considerations
- Electrical requirements: Determine the available voltage (110V vs 240V) and the appropriate amperage. Tankless models often demand higher amperage and dedicated circuits. Verify breaker size and wire gauge before installation.
- Flow rate and point of use: Match the unit’s GPM rating to the number of fixtures you expect to run simultaneously. Higher flow rates can support multiple sinks or showers, while smaller units are better for single-use applications.
- Size and installation location: Consider under-sink, cabinet, or wall-mounted placements. Compact designs are ideal for apartments or RVs, but ensure venting and clearance requirements are met if applicable.
- Temperature control and display: Digital displays or remote controls offer precise setpoints and easier monitoring. Look for models with thermostats that auto-shutoff at the desired temperature for safety.
- Safety features: Leaks, overheat protection, dry-fire protection, and water-quality safeguards reduce risk. ETL or UL certifications indicate compliance with safety standards.
- Energy efficiency: Self-modulating technology and efficient recovery reduce standby losses and electricity costs over time, especially for point-of-use installations.
- Maintenance needs: Some units include enamel-coated tanks or separate components to minimize corrosion. Check warranty coverage and ease of access for servicing.
- Compatibility with existing plumbing: Confirm thread sizes (NPT connections), inlet/outlet locations, and whether adapters are needed for smooth installation.
