Drakken manufactures the iHeat line of tankless water heaters for longevity, eco-friendliness and energy efficiency.  For nearly 2 decades this manufacturer has been thinking outside the box. One of the advantages iHeat has over many tankless water heaters in their price range is innovation! Using only the most appropriate materials such as stainless steel heat exchangers and housing, as well as robust inlet and outlet temperature sensors, the iHeat line is a notch above most heaters in their class.
