Product Details
The Eemax SPEX2412 FlowCo is a precision-engineered 120V tankless water heater designed for point-of-use applications where electrical capacity is limited. Operating at 2.4kW, this unit is specifically designed to run on a 20-amp dedicated circuit, making it one of the easiest thermostatic heaters to integrate into existing structures. It solves the problem of "lukewarm" water at remote handwashing stations by providing an instant, electronically controlled temperature rise at the faucet, ensuring consistent comfort and compliance with health codes.
Key Features:
- Thermostatic Temperature Control: Microprocessor-driven logic maintains an outlet temperature within $+/- 1^\circ\text{F}$ of the set point, eliminating the risk of temperature spikes or "sandwiching."
- Optimized for 20A Circuits: Specifically rated at 20 Amps, allowing for installation in locations where 30-amp or 240V power is not feasible.
- Ultra-Low Activation: Starts heating at just 0.3 GPM, ensuring compatibility with modern ultra-low-flow and sensor-operated commercial faucets.
- 360-Degree Mounting: The compact, durable chassis can be installed in any orientation, making it the perfect fit for cluttered under-sink environments.
- Ni-Chrome Element: Features high-grade Ni-Chrome heating coils that are resistant to calcification and designed for rapid heat transfer and long-term reliability.

Installation & Maintenance Tips:
- Air Purging: Before turning on the electrical breaker, run water through the heater for at least 2 minutes to ensure all air is purged. This prevents "dry-firing" the heating element.
- Dedicated Circuit: The SPEX2412 must be hardwired into its own dedicated 20-amp circuit. Sharing the circuit with other outlets or appliances will likely cause the breaker to trip.
- Inlet Filter Screen: This unit includes a filter screen to protect the sensors. In areas with high sediment, check and clean the filter every 6-12 months to maintain proper flow activation.
- Mounting: Use the provided wall bracket. Because of its lightweight design, it can be mounted directly to the wall or the cabinet side-wall without additional reinforcement.
Common Uses/Applications:
- Small Office Restrooms: Ideal for single sinks in professional buildings where 120V/20A power is standard.
- Employee Breakrooms: Provides instant hot water for handwashing and cleaning light-duty utensils.
- Retail Hand-Wash Stations: A compact solution for kiosks and small retail spaces that must meet health department requirements.
- Home Wet Bars: Delivers instant hot water for prepping drinks or washing glassware in remote areas of the home.
Common Questions:
- Q: Is this model powerful enough for a kitchen sink?
- A: The SPEX2412 is best for handwashing. With a 33°F rise at 0.5 GPM, it is perfect for a restroom sink but may not provide enough heat for greasy dishes in a high-flow kitchen faucet.
- Q: What is the maximum temperature this unit can reach?
- A: The unit is factory set to a safe limit (usually 105°F - 120°F), but it can be adjusted internally to a maximum of 140°F for applications requiring higher sanitation temperatures.
- Q: Can I use this with a standard 15-amp outlet circuit?
- A: No. The unit draws 20 Amps and requires a dedicated 20-amp breaker and 12-gauge wire to operate safely and prevent fire hazards.
The Eemax SPEX2412 FlowCo is the smart, space-saving choice for adding precise, thermostatic hot water to any location where a standard 20-amp/120V electrical circuit is available.
