Description: Eemax SPEX3012 FlowCo™ Non‑Thermostatic Point‑of‑Use Tankless Electric Water Heater

The Eemax FlowCo™ SPEX3012 delivers endless hot water right at the faucet, eliminating storage tanks, standby heat loss, and wasted energy. It activates only when water is flowing—achieving up to 99% energy efficiency—with a flow switch that ensures on-demand heating. Ideal for applications such as handwashing sinks, kitchen and bar setups, and utility fixtures, this compact unit mounts directly to the wall using a single-cold-water-line design. Its tankless construction helps reduce calcification, sediment buildup, and Legionella growth from standing water.

Feature Specification Benefit
Power Rating 3 kW, 120 V, 25 A, 1 phase Efficient, point-of-use heating without excessive electrical demand
Flow Activation Activates at ≥ 0.25 GPM Ensures heating begins promptly at low-flow fixtures
Maximum Flow Rate Up to 1.5 GPM (model dependent) Serves small sinks and fixed flow applications reliably
Temperature Range Approx. 90–130 °F Suitable for handwashing and sink use
Pressure Rating 30–150 psi Durable for most residential and commercial water lines
Dimensions ~9.7″ H × 5.25″ W × 3″ D; weight ~3–4 lb Compact, installs easily under sinks or behind fixtures

How It Works

  • Demand-Driven Heating
    Water flow triggers the heater’s nichrome cartridge, heating instantly—no standby energy waste.

  • Flexible Mounting
    Omnidirectional installation allows mounting in any orientation, fitting into tight spaces and ADA-compliant setups.

  • Intelligent Safety Controls
    Includes InfoCue™ LED status indicators, SafeStart™ to prevent dry-fire incidents, and self-diagnostic mechanisms for protection.

  • Simple Installation

  • Connects to one cold-water line via 3/8″ compression fitting—no soldering, no T&P valve needed (subject to code)

Key Features

  • Point-of-Use Efficiency: On-demand heating with zero standby energy loss

  • Ultra-Compact: Conceals neatly in small spaces—ideal under sinks

  • Smart Safety: Self-diagnostics, LED alerts, SafeStart™ dry-fire protection

  • Lead-Safe: Wetted components meet low-lead standards (ANSI/NSF 372)

  • Made in USA: High-quality construction backed by domestic manufacturing


Ideal Applications

  • Single lavatory, sensor, or metering faucets (handwashing)

  • Kitchen, bar, or utility sinks with consistent low-flow demand

  • Fixed-flow fixtures in modular buildings or tenant spaces

  • Spaces without room for traditional tanks, or where energy-efficient onsite heating is needed

Installation

Turn off the circuit breaker connected to the electrical line where the unit will be installed

Mount the heater in any orientation near the fixture, such as under a sink or behind a wall panel

Connect the cold water supply to the unit’s inlet using a 3/8″ compression fitting

Connect the hot water outlet of the unit to the faucet or fixture

Wire the unit to a dedicated 120V circuit using 10 AWG wire (25 amp maximum draw)

Turn the water supply back on and check all fittings for leaks

Restore power at the breaker; the unit will activate when water begins to flow

Note: This unit is non-adjustable and is not designed for showers, recirculation loops, or whole-home use. Professional installation is recommended. Always disconnect power before servicing.
