HOT ! Eemax SPEX4208 FlowCo 208V Tankless Electric Water Heater | 4.1kW

Eemax SPEX4208 FlowCo Thermostatic Tankless Electric Water Heater

Product Details

The Eemax SPEX4208 FlowCo is a high-efficiency tankless water heater specifically engineered for 208V electrical systems, common in commercial and industrial settings. Delivering 4.1kW of power, this unit provides a reliable, thermostatic hot water solution for point-of-use fixtures. It solves the performance loss often seen when installing 240V heaters on 208V circuits by providing a calibrated power output that ensures consistent temperatures. Compact and remarkably versatile, the SPEX4208 is the professional’s choice for dedicated handwashing in office buildings, schools, and retail environments.

Key Features:

• 
  208V Optimization: Purpose-built for 208V power, ensuring you get the full 4.1kW of heating capacity without the \"de-rating\" performance drop associated with standard 240V models.


• 
  Thermostatic Accuracy: Integrated microprocessor technology maintains a precise outlet temperature ($+/- 1^\\circ\\text{F}$), preventing fluctuations even as incoming flow rates change.


• 
  0.3 GPM Activation: Designed to trigger heating at ultra-low flow rates, making it perfectly compatible with LEED-compliant water-saving faucets and sensor sinks.


• 
  Mount Anywhere: Features a 360-degree mounting design, allowing the unit to be installed in any orientation to fit into tight under-sink cabinets or around existing plumbing.


• 
  Energy Efficiency: Only draws power when the faucet is turned on, eliminating the standby heat loss of traditional tank heaters and reducing overall energy costs.

Note: All FlowCo SPEX models feature THERMOSTATIC control as standard, ensuring output accuracy of +/- 1°F. *Temperature rise values exceeding 100°F are theoretical; the unit will maintain your set point (typically 105°F-110°F). De-rating for 208V: 240V models installed on 208V circuits will yield 25% less heating capacity.

Installation & Maintenance Tips:

• 
  Check Your Voltage: This model is specifically for 208V circuits. Installing this on a 240V circuit will cause the unit to draw significantly more amperage than rated and may damage the heating elements or trip the breaker.


• 
  Prevent Dry-Firing: Always run water through the unit for at least two minutes to purge all air before turning the electrical power on for the first time.


• 
  Inlet Filter Cleaning: Ensure the factory-installed inlet filter screen is checked annually. Debris can prevent the 0.3 GPM sensor from activating the heating sequence.


• 
  Hard Water Areas: If your local water is high in mineral content, consider a scale-inhibitor filter on the intake to maintain the efficiency of the Ni-Chrome heating elements.

Common Uses/Applications:

• 
  Commercial Office Buildings: Provides instant hot water for restrooms on 208V 3-phase building power.


• 
  Educational Facilities: Safe, thermostatic water for handwashing stations in schools and dormitories.


• 
  Retail Facilities: Compact enough for strip mall employee restrooms or single-sink breakrooms.


• 
  Laboratory Sinks: Offers the steady, precise temperatures required for clean-up in sensitive lab environments.

Common Questions:
