Undersink Electric Tankless Heater

This Chronomite CM-20L/120 unit supplies hot water on demand at a single undersink location. It operates on 120V AC single-phase power and draws 20 A, consuming 2,400 W during operation. The compact housing measures 6.25 in high, 9.63 in wide and 2.75 in deep, fitting inside standard cabinets. It is rated for indoor commercial and residential use.

Replaces Storage Tank for Low-Flow Fixtures

The heater activates at a minimum flow of 0.2 gpm and delivers up to 1 gpm, making it suitable for hand-washing sinks or similar low-demand points. It removes the standby losses and space requirements of a tank heater where only modest hot-water volumes are needed. The jump is worthwhile when the fixture flow stays within the 0.2 to 1 gpm window and a 120 V circuit is already available.

Limited by 120 V Supply and Single Outlet

At 2,400 W the unit cannot raise temperature at higher flow rates, so it cannot serve showers or multiple fixtures simultaneously. The thermostat is fixed, delivering between 110 °F and 160 °F without user adjustment. A 3/8 in cold inlet and 20 A branch circuit are required, and the product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

What size cold-water inlet fitting does the CM-20L/120 require?

The unit uses a 3/8 in cold inlet connection for the supply line.

Which step is often missed when wiring this 120 V heater?

A dedicated 20 A circuit must be provided; sharing the circuit causes nuisance tripping.

How often should the inlet screen be cleaned on this model?

Inspect and clean the screen every six months or whenever flow drops below 0.2 gpm.
