Compact Undersink Electric Heater

The Chronomite Instant-Flow Micro CM-15L/240 is a tankless water heater designed for undersink installation in commercial and residential settings. It delivers a fixed 110 Degrees F output at a maximum flow rate of 1 gpm. The unit activates at a low 0.2 gpm, making it suitable for hand-washing stations or low-demand fixtures. Its compact dimensions allow fitment in tight cabinet spaces.

Thermal Performance and Electrical Draw

The heater operates on 240V AC single-phase power and draws 15 A with a power consumption of 3,600 W. Because the thermostat is not adjustable, the delivered temperature remains constant at 110 Degrees F. The compression-type cold inlet accepts 3/8 in connections. Indoor-rated construction suits typical point-of-use installations.

Included Wiring and Compliance Notes

A 14 AWG cord conductor is supplied for electrical connection. No additional accessories or software are bundled with this part. California Proposition 65 warnings apply: the product contains chemicals known to cause cancer and birth defects or other reproductive harm. The item is not restricted from sale in any listed state.

Questions about this item

How do I wire the 14 AWG cord to a 240 V single-phase supply and what is the common mistake?

Connect the 14 AWG conductors to a dedicated 15 A, 240 V circuit; the step often missed is forgetting that the heater draws 15 A continuously, so the breaker and wiring must be rated for that full load.

Which component will need replacement first in a commercial setting?

The heating element is the primary wear item; with 3,600 W output and no adjustable thermostat, it cycles at full power whenever the 0.2 gpm activation threshold is met, so plan on element replacement over time.

What limits the unit during a long, continuous draw?

The fixed 110 °F maximum delivered temperature caps output; once inlet water approaches that temperature the heater cannot raise it further, so sustained high-demand use hits the temperature ceiling first.
