Compact on-demand hot water for focused residential and light commercial use
Introduction
Hot water access plays a vital role in daily comfort, hygiene, and productivity. From washing hands and dishes to showering and cleaning, the reliability of a water heating system affects how smoothly a home or workspace functions. Traditional tank water heaters, while common, often struggle with limited capacity, wasted energy, and bulky installation requirements. These limitations have driven many homeowners and small business operators to explore electric tankless water heaters as a modern alternative.
The Eemax EEM24013 Electric Tankless Water Heater is designed for users who want instant, consistent hot water in a compact and efficient form. Built for point-of-use applications and small residential setups, this 13-kilowatt unit delivers on-demand hot water without the drawbacks of a storage tank. Its self-modulating technology, digital temperature display, and space-saving design make it particularly appealing for apartments, offices, and targeted water outlets.
This in-depth review examines the Eemax EEM24013 from every angle, including design, performance, energy efficiency, safety, installation requirements, and real-world usability. By the end, you will have a clear understanding of where this model excels and which situations it is best suited for.
Product Overview
The Eemax EEM24013 is a 240-volt electric tankless water heater engineered to provide continuous hot water exactly where it is needed. Rather than heating and storing water in a tank, it heats water instantly as it flows through the unit. This approach eliminates standby heat loss and ensures a steady supply of hot water within the system’s designed capacity.
This model is well-suited for point-of-use installations, such as a single sink, or for small apartments in warmer climates where incoming water temperatures are higher. Its compact footprint allows installation in tight spaces while maintaining dependable heating performance.

Design and Build Quality
One of the defining characteristics of the Eemax EEM24013 is its compact and practical design. Measuring just 8 inches wide and 11.5 inches high, this unit can be installed in locations where traditional water heaters would be impractical or impossible.
Compact and Space-Efficient
The small footprint makes it ideal for:
- Under-sink installations
- Utility closets
- Office break rooms
- Small apartments
- Commercial handwashing stations
Despite its size, the unit is built with durability in mind. The housing protects internal components from heat stress while allowing easy access for installation and servicing. The clean, modern appearance also helps it blend discreetly into residential and commercial environments.
Heating Performance and Water Delivery
Performance is central to any tankless water heater, and the EEM24013 is designed to deliver reliable hot water for focused applications.
Instant and Continuous Hot Water
Because the system heats water only when a tap is opened, users experience near-instant hot water without waiting for a tank to refill or reheat. This is especially beneficial in high-use areas where quick access to hot water is essential.
In colder climates, the unit is capable of supplying hot water to one sink reliably. In warmer climates, where incoming groundwater temperatures are higher, it can support one shower and one sink simultaneously.
Self-Modulating Technology Explained
One of the standout features of the Eemax EEM24013 is its advanced self-modulating technology. Unlike fixed-output heaters that operate at full power regardless of demand, this unit adjusts its energy consumption in real time.
Intelligent Energy Use
The heater continuously monitors water flow and temperature, delivering only the amount of power needed to achieve the desired output. This results in:
- Improved energy efficiency
- Reduced electrical strain
- More stable water temperatures
By matching energy input to actual demand, the system avoids unnecessary power usage while maintaining consistent performance.
Digital Temperature Display and Controls
Ease of use is enhanced by the integrated digital temperature display. This feature allows users to monitor and adjust water temperature with precision.
Adjustable Settings for Comfort
The digital interface provides clear feedback, making it easy to fine-tune the output temperature based on preference or application. Whether used for handwashing, dishwashing, or light showering, the display ensures accurate temperature control without guesswork.
This level of control adds an extra layer of safety and convenience, particularly in environments where consistent temperature is important.
Energy Efficiency and Cost Considerations
Tankless water heaters are widely recognized for their efficiency advantages, and the EEM24013 follows this trend.
Heating Only What You Need
Traditional tank heaters continuously heat stored water, even when not in use. In contrast, the Eemax EEM24013 heats water only when demanded. This eliminates standby heat loss and can significantly reduce overall energy consumption.
For point-of-use applications, this efficiency translates into:
- Lower electricity waste
- Reduced operating costs
- Improved long-term value
Installation Requirements and Electrical Needs
The EEM24013 operates on a 240-volt electrical system and requires proper electrical infrastructure to function safely.
Installation Considerations
- 240V electrical supply required
- Proper circuit breaker sizing
- Professional installation recommended
Because of the electrical demands, installation by a licensed electrician and plumber is strongly advised. Correct installation ensures optimal performance, safety, and compliance with local electrical codes.
Safety and Reliability Features
Safety is a critical factor in any electric water heater, and Eemax integrates proven protections into this model.
Built-In Safeguards
The unit’s design ensures stable operation by regulating power input and monitoring internal conditions. The separation of electrical and water pathways reduces the risk of electrical leakage and internal corrosion.
These safety-focused design elements contribute to long-term reliability and user confidence.
Climate-Based Performance Flexibility
The performance of any tankless water heater depends on incoming water temperature, and the EEM24013 is no exception.
Cold Climate Applications
In colder regions, the unit performs best as a dedicated point-of-use heater for a single sink. This makes it ideal for:
- Bathroom sinks
- Kitchen prep sinks
- Commercial handwashing stations
Warm Climate Applications
In warmer climates, where groundwater temperatures are higher, the heater can support more demanding uses, such as one shower and one sink simultaneously.
Residential and Commercial Use Cases
The versatility of the EEM24013 allows it to serve a wide range of applications.
Residential Uses
- Apartments and condos
- Guest bathrooms
- Remote sinks
- Home offices
Commercial Uses
- Small offices
- Retail spaces
- Salons
- Food service prep areas
Its compact size and dependable output make it particularly useful where hot water is needed at specific points rather than throughout an entire building.
Maintenance and Long-Term Care
Tankless systems typically require less maintenance than tank-based heaters due to the absence of stored water.
Maintenance Considerations
- Periodic inspection of electrical connections
- Descaling in areas with hard water
- Ensuring proper ventilation and clearance
With routine care, the Eemax EEM24013 is designed to provide consistent service over many years.
Comparison with Traditional Tank Water Heaters
When compared to traditional tank heaters, the EEM24013 offers several clear advantages:
- Endless hot water within capacity limits
- No bulky storage tank
- Reduced energy waste
- Faster access to hot water
However, it is important to match the unit size to actual hot water needs. This model is optimized for targeted use rather than whole-house demand.
Overall Value Assessment
The Eemax EEM24013 Electric Tankless Water Heater delivers excellent value for users who need reliable, on-demand hot water in a compact form. Its self-modulating technology, digital controls, and efficient performance make it a practical choice for both residential and light commercial applications.
When properly sized and installed, it offers a dependable alternative to traditional tank heaters, particularly in spaces where efficiency and size matter most.
Conclusion
The Eemax EEM24013 Electric Tankless Water Heater stands out as a focused, efficient, and intelligently designed solution for point-of-use and small-scale hot water needs.
