Residential Electric Tankless Water Heater

The Eemax HA013240 is a residential electric tankless water heater operating at 240V AC single phase. It delivers hot water on demand with a power consumption of 13,000 W. The unit features an adjustable thermostat with a digital display and keypad for temperature control between 80 and 140 degrees F. It is designed for indoor installation in general-purpose residential applications.

Installation Requirements and Activation

Installation requires a 240V AC single-phase supply capable of delivering 54 A. The cold water inlet uses a 1/2 in connection. The heater activates at a minimum flow of .3 gpm and can supply up to 4.8 gpm. Its compact dimensions of 11.5 in height, 8 in width and 3.75 in depth allow flexible placement, but the high current demand means the electrical circuit must be correctly sized before mounting.

13 kW Heating Capacity

The 13,000 W heating element determines the maximum temperature rise at a given flow rate. At the peak flow of 4.8 gpm the temperature increase will be lower than at reduced flows. Buyers needing higher simultaneous hot water delivery or a greater temperature rise at full flow should consider a higher-kW model. This unit suits point-of-use or low-demand whole-house scenarios where the electrical supply supports 54 A.

Questions about this item

How do I verify the unit is heating water to the set temperature after installation?

Run a hot-water tap at a flow above 0.3 gpm and check the digital display; it will show the delivered temperature between 80 and 140 °F as the thermostat dial is adjusted.

What comes in the box and what must I supply separately?

The heater itself is included; you must provide a 240 V single-phase circuit rated for 54 A, 1/2 in cold-water piping, and any required mounting hardware.

Is the 13 kW model the right choice for a single shower or a whole house?

At 4.8 gpm maximum flow, the 13 kW unit suits one high-flow shower or a point-of-use application; larger homes with simultaneous draws need a higher-capacity model.
