Undersink Electric Tankless Water Heater

The Eemax SPEX2412 is a compact electric tankless water heater designed for indoor point-of-use applications. It serves commercial and residential fixtures including sensor faucets, kitchen sinks, metering faucets and lavatory faucets. The unit mounts beneath a sink to provide hot water on demand without a storage tank.

Single-Phase 120 V 20 A Power Requirement

This heater operates on 120 V AC single-phase power and draws 20 A at 2 400 W. A dedicated circuit with the correct breaker and wiring is essential for safe operation. Installations without this electrical capacity cannot support the unit.

The heater delivers up to 1.5 gallons per minute and activates at a minimum flow of 0.25 gpm. It connects via 3/8-inch cold water inlet fittings and produces outlet temperatures between 70 and 140 degrees F. The 10.75-by-5.25-by-3-inch enclosure fits tight undersink spaces.

Questions about this item

What does the 1.5 gpm maximum flow rate mean for daily use?

It delivers up to 1.5 gallons per minute, suitable for a single sink or sensor faucet but not for simultaneous fixtures.

How does the 120 V single-phase supply limit the heater?

The 120 V single-phase input caps power at 2,400 W and 20 A, so temperature rise depends on inlet water temperature and flow.

Will the 10.75 in height and 3 in depth fit under my cabinet?

The unit measures 10.75 in high, 5.25 in wide and 3 in deep, designed for undersink installation with 3/8 in cold inlet.
