It includes a digital display and touch controls for easy temperature setting, designed for 110℉ hot water in seconds and energy efficiency around 98%.
Buying Guide
- Flow needs: Determine GPM requirements for your shower(s). A typical shower uses 1.5–2.5 GPM; larger homes may require higher capacity or multiple units.
- Voltage and wiring: Most models use 240V, with breakers and wire gauges specified by each unit. Ensure your electrical panel supports the required load or plan for a service upgrade.
- Self-modulating technology: Look for models that regulate power based on flow and temperature to maximize energy efficiency and minimize overshoot or temperature swings.
- Compact installation: Tankless units are wall-mounted or installed near point of use. Consider available space, venting (if any), and proximity to showers for best performance.
- Durability and safety: Check for ETL or UL certifications, water protection features, dry-boil protection, and anti-corrosion measures to extend unit life.
- Maintenance: Some models require periodic flushing to prevent mineral buildup; review maintenance needs for your water hardness and usage.
- Cost versus savings: While prices vary, tankless systems typically reduce ongoing energy costs and save space, offsetting upfront installation expenses over time.
- Compatibility: If you have existing plumbing or a multi-point layout, verify that selected models can deliver consistent temperature across multiple fixtures.
