Rheem electric tankless hot water heaters are a great alternative to standard tanked electric water heaters because they provide continuous hot water on demand. Each Rheem tankless water heater features a compact design that provides homeowners flexibility when choosing where to install their tankless water heater. Tankless water heaters can provide significant savings over a standard steel tank water heater. Steel tanked heaters can lose up to 30 degrees of water temperature over a 24-hour period causing the need for multiple element cycles to re-heat the water. Rheem’s electric tankless water heaters only activate when you need hot water.
- It’s compact design fits almost anywhere.
- On demand, consistent, endless hot water.
- Industry leading low flow activation – as little as 0.3 GPM.
- External temperature controls to adjust temperature in increments of 1°F.
- Robust copper immersion heating elements with brass top for increased durability and easy replacement.
