Best for small sinks or kitchens needing quick hot water without preheating. The unit raises water temperature quickly (to about 82°F–131°F depending on flow). It supports Fahrenheit or Celsius and includes safety protections. Note: Not suitable for showers due to flow requirements.
Rheem 18kW 240V Tankless Electric Water Heater
Rheem’s model uses external digital thermostatic control with an LED display and self-modulation to match hot water demand. It’s designed for higher flow, up to 4.4 GPM, making it suitable for small apartments or bathrooms with steady usage. Best for households needing reliable, continuous hot water and compatibility with copper immersion elements. It may require professional installation due to 240V wiring.

Not ideal for showers due to flow requirements.
Buying Guide: Key Considerations
- Water demand and flow rate: Choose based on the number of fixtures and typical usage. Tankless units excel at point-of-use tasks, while small storage models are better for steady supply.
- Electrical requirements: Look at wattage and circuit needs. Higher-capacity units may require dedicated circuits and professional installation.
- Space and installation: Under-sink and wall-mounted tankless models save space but may require professional mounting and proper clearances.
- Temperature control: Digital displays and thermostatic control improve accuracy. Some units offer Fahrenheit/Celsius settings for convenience.
- Safety features: IP ratings, dry-boil protection, and automatic shutoff reduce risk. Check for leakage protection and overheat safeguards.
- Energy efficiency: Tankless models typically save energy by heating on demand. Storage heaters can provide ready hot water but may incur standby losses.
Frequently Asked Questions
- Q: Do these units require professional installation? A: Some models can be DIY, but high-wurst wattage units and 240V configurations often require a licensed electrician.
- Q: Can I install a tankless water heater under the sink? A: Yes, many models are designed for point-of-use and compact spaces.
