When you set it to the temperature you want, it comes out at a steady and consistent rate. Typical water heaters hold a lot of hot water, but you have to wait for the heat to recover once it's all used up. Our products will always keep showers hot, even if there are many in a row and are long. The small size of the heater makes for a convenient installation in smaller spaces like kitchens, bathrooms, laundry rooms, and even places like studios, apartments, and cabins. Our product has an automatic memory feature that stores past input and saves you the hassle of repeatedly setting the temperature. This lead-free heater is environmentally friendly, as it saves on water wastage and doesn't vent.

Review: Instant hot water - This unit services a shower and sink in a bathroom at the far end of the house. It does a very good job. The water is hot, even with a long shower. Much better than running a long hot water line and wasting water waiting for it to get hot.

Scald to freeze back and forth as peevish as desertcart in delivering purchase insurance paperwork. ## Features - ETL Certified;Endless hot water:No need to preheat before using.Automatically memorized temperature settings;Conversion between Celsius and Fahrenheit - Easy management and simple adjustments: LCD panel allows you to program the exact desired water temperature ( 1 degree accuracy) thereby optimizing energy consumption - Power:11 KW; Voltage:240 V;Maximum Amperage: 50 Amp;1/2 Inch NPT water connections;Temperature Setting range: 86-125 ℉/ 30-52 ℃ - Over-temperature protection: the electricity will be cut off to avoid getting scalded when the outlet water temp. reaches over 149℉/65℃ - Micro-computer control, Adopting patent heating technology.
