iHeat logoThe iHeat AHS Series tankless water heaters save energy by turning on only when you need hot water. Flow sensors detect outgoing and incoming water temperature as well as the flow rate to automatically adjust the heating elements to precisely achieve the temperature you set. These temperature sensors don't touch the water, which means that they last much longer, and require less maintenance. Plus, AHS models have built-in safety features to protect you and your children from scalding from overheated water.

iHeat AHS water heaters are in the same class as the Ecosmart ECO18 through ECO27 shown in the Related Gadgets tab near the bottom of this page. Here are some advantages:

  »  The flow sensor is inside the inlet pipe, eliminating the risk of leaks from metal and plastic joints.
  »  The electronic control board is made with higher-quality surface mount design.
  »  Features a touch screen display instead of a clunky, imprecise knob.
  »  AHS heaters can be diagnosed through the USB port at the bottom of the unit. Refer to the last page of the manual.
