The ATMOR 900 series electric tankless water heater revolutionizes hot water heaters, providing you with unlimited hot water when you need it without the wait. The unit automatically activates once it senses water flow and shuts off when it stops, helping you lower your water consumption and eliminate costly water waste. This electric water heater is an eco-friendly, efficient and convenient solution, delivering an endless supply of hot water instantly only when you need it. It is suitable for both residential and commercial applications, even in your RV. Unlike a gas water heater, the compact design requires no venting, giving you the flexibility to install anywhere inside your home or garage.
