Eemax SPEX3512 vs EEM24013 Comparison
Voltage and Power
The SPEX3512 operates on a standard 120-volt circuit with 3.5 kilowatts of heating power. This makes it suitable for simple under-sink installations where a dedicated 240-volt line is not available. The EEM24013 is also electric but does not list its specific voltage or wattage in the provided data. You must check your electrical panel for the EEM24013 to ensure compatibility. The SPEX3512’s 120-volt rating is a clear advantage for easy retrofitting into existing bathroom or kitchen outlets without major electrical upgrades.
Dimensions and Size
Size matters for tight cabinets. The SPEX3512 measures 9.75 inches in height, 5 inches in width, and 3 inches in length. It weighs just 3.1 pounds. The EEM24013 is larger, measuring 11.5 inches in length, 8 inches in width, and 3.75 inches in height. The SPEX3512 is narrower and shallower, making it easier to fit into small vanity spaces. If you have limited room under a sink, the compact footprint of the SPEX3512 is the better choice for installation.
Temperature Control
The SPEX3512 features self-diagnostics and intelligent controls that adjust output based on flow rate. It provides a 41°F temperature rise at 0.5 gallons per minute. The EEM24013 uses self-modulating technology to adjust energy input based on need. However, the SPEX3512 provides specific performance data regarding its temperature rise. This allows you to calculate if it meets your hot water needs. The EEM24013 lacks specific flow rate and temperature rise data in the provided specs.
Installation Flexibility
Both units are designed for point-of-use installation. The SPEX3512 can mount in any orientation, giving you flexibility in how you place it in a cabinet. The EEM24013 is also compact but does not specify mounting orientation in the data. The SPEX3512’s ability to mount in any orientation is a practical benefit for irregular cabinet spaces. It simplifies the installation process for you, regardless of the available space layout.
Color and Finish
The SPEX3512 comes in white, which blends well with standard white cabinetry and plumbing fixtures. The EEM24013 is blue. This is a cosmetic difference that does not affect performance. You should choose the color that matches your existing decor. The SPEX3512’s white finish is a neutral option for most bathrooms. The EEM24013’s blue finish may stand out if the unit is visible. This aspect is a tie as it depends on personal preference.
Which Eemax Tankless Model Fits You
Standard outlet users
The SPEX3512 runs on 120 volts. You can plug it into a standard wall outlet without upgrading your electrical panel. It delivers a 41°F temperature rise at 0.5 GPM. This output works well for a single sink. The 3.5 kW power handles light hot water needs efficiently.
Space-constrained installs
This unit measures 9.75 by 5 by 3 inches. It is significantly narrower and deeper than the EEM24013. The compact footprint allows installation in tight under-sink cabinets. You save valuable storage space. The self-modulating technology ensures it only uses energy when you need hot water.
Continuous flow seekers
The EEM24013 is designed for endless hot water. It uses advanced self-modulating technology to adjust energy input based on demand. This provides instant, consistent heat. The larger 11.5-inch length supports higher flow requirements. Choose this model if you need a steady stream for longer usage periods.

Frequently asked questions
Can the Eemax SPEX3512 handle multiple sinks?
No. This unit is designed for single sink point-of-use applications. Its 3.5 kW output and compact size limit its flow rate to low-demand tasks. You should not install it for showers or kitchen sinks with high flow needs. It works best for handwashing or small bathroom basins where water usage is minimal.
Does the EEM24013 require a special outlet?
Yes. The EEM24013 is a higher-power electric heater that typically requires a dedicated 240-volt circuit. You cannot plug it into a standard 120-volt wall socket. You must verify your home electrical system can support the amperage before installation. This makes it suitable for locations with existing high-voltage wiring.
Which model is smaller and easier to hide?
The SPEX3512 is the more compact choice. It measures 5 inches wide and 9.75 inches tall. The EEM24013 is larger at 8 inches wide and 11.5 inches long. If you need a unit that fits tightly under a small vanity, the SPEX3512 offers a smaller footprint for discreet installation.
Are both heaters electric?
Yes. Both the EEM24013 and the SPEX3512 operate on electric power. They do not use gas or propane. This means you do not need ventilation for exhaust gases or a gas line connection. You only need access to the appropriate electrical circuit for each specific model's voltage requirements.
What is the best use for the SPEX3512?
It is ideal for single sink point-of-use hot water. The 3.5 kW heating element provides endless hot water for low-flow fixtures. You can install it directly under a bathroom sink or a small utility sink. It is not intended for high-demand areas like showers or large kitchen faucets.
Does the EEM24013 have self-modulating technology?
Yes. The EEM24013 uses efficient self-modulating technology to deliver endless hot water. It adjusts its power output based on the incoming water temperature and flow rate. This helps maintain consistent water temperature without wasting energy. It is a key feature for users needing reliable hot water at a single sink.
Can I install these units myself?
You can install them if you have the right skills. The SPEX3512 connects to a 120-volt circuit, which is easier for some homeowners. The EEM24013 requires 240-volt wiring and higher amperage handling. Always check local codes. Electrical work on tankless heaters often requires a licensed professional for safety and compliance.
