ATMOR ThermoPro Electric Tankless Water Heaters revolutionize hot water heaters with smart flow technology that provides you with unlimited hot water when you need it, without the wait. By automatically activating once water flow is sensed and shuts off when it stops, you'll lower your water consumption and eliminating costly water waste. This eco-friendly unit features the advanced ThermoPro self-modulating system that regulates the amount of energy required to heat water, delivering major savings on your energy bill. The easy-to-use, digital panel gives you full control of the unit for the perfect water temperature every time, while the splash-proof IP54 certifications keep the unit safe and dry. Best of all, unlike a gas water heater, the compact design requires no venting, giving you the flexibility to install anywhere inside your home or garage. Perfect for moderate to warm climates, 18kW/240V, 3.7 GPM capacity is ideal for an apartment or small home running up to three applications at once, such as: a showerhead (1.5 GPM), kitchen sink (1 GPM), and bathroom sink (0.5 GPM) or two shower heads and a bathroom sink at inlet temperatures of 73°F.  Remember inlet temps vary by location and seasonality. Colder climates limit the number of applications that can run simultaneously. Selecting the right water heater depends on your incoming water temperature, flow rate, and desired output temperature. To help with this, please see our selection guide below or call our support team at 888.783.6082.
