About this item

Product details

The Atmor 800 series point-of-use tankless electric water heater is an eco-friendly, efficient and convenient solution that delivers a continuous supply of hot water instantly, without the wait and worry of running out. The advanced on-demand water heating technology will automatically turn on and off by sensing water flow, helping you to reduce water consumption, eliminate costly water waste, and save on energy costs.

The compact footprint of this water heater saves you space by simply installing it against the wall either under the sink out of sight or near the point of use, where its elegant design blends into your home environment among other appliances. Unlike a gas water heater, the compact design requires no venting, giving you the flexibility to install anywhere inside your home, office, garage, or even an RV.

Atmor also offers a great value with the assurance of the worry-free warranty–7 years leakage free and 2 years parts only. (IMPORTANT: inlet temps vary by location and seasonality. Selecting the right water heater depends on your incoming water temperature, flow rate, and desired output temperature. – See Performance Guide Images and/or Manual before purchasing.) Should you have any questions and need sizing this unit for your hot water need, give our technical support agents a call for further assistance at 1-888-783-6082, Monday – Friday, 9 AM-5:30 PM EST.
