Product Data Table

Compact Design for Flexible Installation

One of the most attractive features of the Eemax EX200TC S is its compact form factor. Traditional tank water heaters often require significant space due to their large storage capacity. In contrast, this tankless model measures only 10 inches wide and 10.5 inches high, making it suitable for installations where space efficiency is important.

Its slim 3-inch depth allows the unit to fit comfortably in tight utility areas, cabinets, or mechanical rooms. This flexibility makes the EX200TC S an excellent option for apartments, offices, commercial environments, and smaller residential properties.

Because the system heats water only when required, there is no need for a bulky storage tank. This space-saving advantage makes tankless technology increasingly popular among modern property owners.

On-Demand Hot Water Performance

The EX200TC S provides hot water instantly when needed, eliminating the delays associated with traditional tank heaters. Instead of waiting for stored water to heat up, the system activates automatically when water flow reaches the minimum activation rate of 1.5 gallons per minute.

At 2.5 gallons per minute, the system can achieve a temperature rise of up to 103°F. This performance capability ensures reliable hot water delivery for sinks, faucets, and other fixtures.

On-demand heating improves convenience while reducing water waste caused by waiting for hot water to reach the desired temperature.

Durable Stainless Steel Heating Elements

The internal heating elements play a critical role in the performance and lifespan of a tankless water heater. The EX200TC S features stainless steel elements designed for durability and consistent heat transfer.

Stainless steel is known for its resistance to corrosion, making it ideal for long-term use in water heating systems. The ability to replace heating elements in the field simplifies maintenance and helps extend the overall lifespan of the unit.

Durable internal components contribute to reliable performance even under demanding conditions.

Reliable Temperature Performance

Temperature consistency is essential for both comfort and safety. The EX200TC S is designed to maintain stable temperature output during operation, ensuring dependable hot water delivery.

Its heating capacity allows the unit to provide consistent performance within its specified flow range. This reliability makes the system suitable for applications where predictable water temperature is required.

Stable temperature output helps improve user comfort and enhances the overall hot water experience.

Professional-Grade Electrical Performance

Operating at 277 volts with a total amperage draw of 72 amps, the EX200TC S is designed for professional installation environments. The unit requires two 36-amp breakers, ensuring safe and reliable electrical operation.

Because tankless water heaters rely on powerful heating elements to heat water instantly, proper electrical configuration is essential for optimal performance.

Professional installation helps ensure that the electrical system meets required specifications.

Proper setup also contributes to safety and long-term reliability.

Efficient Water Heating Technology

Tankless water heaters are recognized for their efficient energy usage compared to traditional tank systems. Because the EX200TC S heats water only when required, it avoids standby heat loss that occurs when stored water gradually cools over time.

This efficient heating approach helps reduce unnecessary energy consumption.

By delivering hot water on demand, the system provides a balance between performance and energy efficiency.

Efficient operation contributes to reduced electricity usage and improved system effectiveness.

Connection Compatibility and Installation Options

The EX200TC S features stainless steel 5/8-inch internal diameter compression fittings compatible with 1/2-inch copper piping.

These standardized connections allow for straightforward integration into existing plumbing systems.

Compatibility with commonly used pipe sizes simplifies installation and supports flexibility in different environments.

Proper connection ensures reliable water flow and consistent heating performance.

Potential Considerations

Because the EX200TC S operates at 277 volts, installation requires proper electrical infrastructure.

Professional installation is recommended to ensure compliance with electrical codes and safety standards.

Flow rate capacity should be evaluated to ensure the unit meets application requirements.

Proper sizing helps achieve optimal performance.

Maintenance and Serviceability

One of the key benefits of the EX200TC S is its service-friendly design. The heating elements are field replaceable, allowing maintenance professionals to service the unit without replacing the entire system.

Periodic inspection may help maintain optimal performance and extend product lifespan.

Routine maintenance requirements are generally minimal compared to traditional tank systems.

Because tankless heaters do not store water, the risk of corrosion associated with storage tanks is reduced.

This contributes to improved longevity and consistent performance.

Comparison to Traditional Tank Water Heaters

Traditional water heaters store heated water in a tank and continuously consume energy to maintain temperature levels. Once the stored hot water is depleted, users must wait for the tank to refill and reheat.

The EX200TC S eliminates these limitations by heating water instantly as it flows through the system.

This allows continuous hot water delivery without interruption.

Tankless systems also reduce standby heat loss, improving overall efficiency.

These advantages make tankless water heaters an attractive option for modern installations.
