Eemax Series Two EX190TC Tankless Electric Water Heater | 19kW 240V Thermostatic

Product Details

The Eemax EX190TC Series Two is a high-output, twin-module tankless electric water heater designed for heavy-duty commercial and residential applications. Delivering 19kW of power at 240V, this unit utilizes two heating modules to provide a significant temperature rise for high-demand fixtures. The "TC" designation signifies advanced thermostatic control, which maintains a precise outlet temperature ($+/- 1^\circ\text{F}$) regardless of flow rate fluctuations. This makes it an exceptional choice for emergency drench showers, multi-fixture restrooms, or high-flow residential faucets where consistent heat is non-negotiable.

Key Features:

• Twin Module Power: Features two independent heating modules working in tandem to deliver higher flow rates and a greater temperature rise than single-module units.
• Thermostatic Control (TC): Microprocessor-controlled logic ensures the water temperature stays exactly where you set it, eliminating the risk of scalding or cold-water spikes.
• High Flow Compatibility: Designed with a 0.7 GPM activation rate, allowing it to handle higher-volume fixtures such as commercial kitchen sinks or multiple lavatories.
• 99% Energy Efficiency: Like all Eemax tankless units, it heats water only when needed, reducing energy consumption and operating costs compared to tank heaters.
• Staged Activation: The unit stages its heating elements based on demand, using only the electricity required for the specific flow rate at any given moment.

Specifications:

• Power Rating: 19.0 kW
• Voltage: 240V (Single Phase)
• Amperage Draw: 80 Amps (Two 40-amp circuits)
• Required Breakers: 2 x 40 Amp (Double Pole)
• Recommended Wire Size: 2 sets of 8 AWG
• Water Connections: 3/4" NPT
• Temperature Rise @ 2.0 GPM: 65°F
• Dimensions: 10" H x 11" W x 3" D

Installation & Maintenance Tips:

• Electrical Requirements: The EX190TC requires two dedicated 40-amp 240V circuits. Ensure your electrical service is rated for the 80-amp total load before installation.
• Water Pressure: This unit is designed for higher-flow applications; ensure your incoming line pressure is between 30 and 150 PSI for optimal performance.
• Internal Filter: Periodically check the inlet filter screen for debris. Because this unit serves high-flow fixtures, keeping the filter clean is vital for maintaining the 0.7 GPM activation.
• Copper Fittings: It is recommended to use copper or stainless steel flex connectors for the water lines to accommodate the high heat output.

Common Uses/Applications:

• Commercial Multi-Lavatory: Can serve up to four 0.5 GPM sensor faucets simultaneously.
• Emergency Eye Wash Stations: The thermostatic "TC" accuracy is critical for safety-compliant tepid water delivery in industrial environments.
• Kitchen Sinks: Ideal for high-flow kitchen sinks in restaurants or office breakrooms that require consistent sanitation temperatures.
• Residential Additions: Perfect for high-demand master bathrooms or "mother-in-law" suites where a high-output dedicated heater is required.

Common Questions:

Q: What is the difference between Series Two and LavAdvantage?

A: Series Two units (like the EX190TC) use a twin-module design to provide roughly double the heating capacity of the single-module LavAdvantage units.

Q: Does it work with 208V power?

A: Yes, but the output will be de-rated to 14.3kW. This will result in a lower maximum temperature and flow rate. For 208V commercial buildings, verify your requirements.

Q: Is the temperature adjustable?

A: Yes, the TC series features an internal adjustment pot that allows you to set the target temperature, which the unit will then maintain automatically.

The Eemax EX190TC Series Two provides industrial-strength performance in a compact chassis, offering the precise thermostatic control needed for high-demand hot water applications.
