Brand: Eemax | SKU: SPEX3512T
Product Overview
The Eemax SPEX3512T LavAdvantage is a highly efficient, point-of-use electric tankless water heater designed to deliver instantaneous hot water for handwashing applications. Operating at 3.5kW and 120V, this microprocessor-controlled heater features precise thermostatic technology that prevents temperature fluctuations. Homeowners, facility managers, and contractors select this compact model for commercial, industrial, and residential lavatories to reduce wait times and eliminate water waste at the fixture.
Key Features:
-
Thermostatic Temperature Control: Microprocessor-driven power modulation monitors and adjusts energy usage to maintain a stable, consistent output temperature within +/-1°F.
-
Ultra-Low Flow Activation: Features an industry-leading turn-on threshold of just 0.2 GPM, making it perfectly suited for water-saving sensor or metering faucets.
-
SafeStart™ Technology: An intelligent internal startup mechanism actively checks for dry-firing conditions upon installation, protecting the heating element from premature damage.
-
Compact Footprint: The space-saving, lightweight design mounts directly under sinks or in tight utility areas, eliminating the need for bulky traditional storage tanks.
-
Vandal-Resistant Enclosure: Encased in a rugged, durable housing designed to protect vital internal components from tampering in public or high-traffic commercial spaces.

Frequently Asked Questions
Does this unit require a temperature and pressure (T&P) relief valve?
According to UL 499 criteria, this tankless water heater is not required to be equipped with a T&P relief valve during normal installation. However, you must always cross-reference your municipal or state plumbing codes to verify if a local variation mandates one.
Can the SPEX3512T be mounted sideways or horizontally?
No. The unit must be mounted strictly in a vertical configuration with the plumbing connections pointing downward. Altering this orientation can trap internal air pockets and will lead to element failure or system damage.
What are the dedicated electrical requirements for this 120V heater?
The SPEX3512T draws a total of 29 Amps. It requires a dedicated 120V electrical circuit, protected by a single-pole 30 Amp circuit breaker, and wired with a minimum conductor size of 10 AWG copper wire.
Can I use this water heater to service a kitchen sink or a shower?
No, this 3.5kW unit is engineered specifically for single-faucet handwashing applications (lavatories). Its lower power output is not designed to support the higher flow rates and temperature demands required for kitchen basins or showering fixtures.
Why We Like It:
The Eemax SPEX3512T is a stellar choice for commercial handwashing stations because it delivers true thermostatic precision at an ultra-low 0.2 GPM activation rate. This combination prevents the cold-water lag common with remote central tanks while seamlessly supporting high-efficiency sensor faucets. Before kicking off your installation, double-check your electrical panel to ensure you have a dedicated 30 Amp breaker and 10 AWG copper wiring ready. Always remember to run water completely through the unit for a minute or two to purge all internal air bubbles before switching on the power to safeguard your heating elements from dry-firing.
