Our top pick: Eemax 1.5-Gallon Mini Tank Electric Water Heater.
How Each Alternative Compares
ThermoMate ES150 1.32 Gal Mini Tank
The ThermoMate ES150 is a slightly smaller 1.32-gallon unit designed for tight under-sink spaces. It shares the 120V electrical requirement of the Eemax, making it a direct swap for standard outlets. Its compact dimensions of 9.65 by 11.4 by 15 inches offer a different footprint, which may fit narrower cabinets better than the Eemax’s 12.5 by 11 by 10-inch profile. You get a similar point-of-use performance for a single sink. This model is ideal if you need a budget-friendly option that prioritizes space efficiency over the Eemax’s slightly larger storage capacity.
Rheem 6.5 kW Point-of-Use Tankless Water Heater
The Rheem RTEX-06T is a tankless unit, which means it heats water on demand rather than storing it. It is significantly smaller, measuring only 6 by 6 by 3 inches, and weighs just 4 pounds. However, it requires a 240V electrical circuit, unlike the Eemax’s 120V plug. This makes it unsuitable for standard outlets. You should choose this model if you have existing 240V wiring and want to eliminate the need for storage space. It provides continuous hot water without the limitations of a small tank, but installation is more complex due to the higher voltage requirement.
VEVOR 12-Gallon 120V Electric Storage Water Heater
The VEVOR 12-Gallon unit offers a much larger storage capacity than the 1.5-gallon Eemax. It is designed for households needing higher hot water volume, not just a single sink. The unit is larger, measuring 16.1 by 16.1 by 23.6 inches, and weighs 40.1 pounds. Like the Eemax, it operates on 120V power. This model is best for users who find the Eemax’s capacity too limiting for multiple fixtures or longer showers. It provides a substantial reserve of hot water, making it suitable for small households or areas where space allows for a bulkier installation.
Thermomate 2.5-Gallon Under-Sink Mini-Tank Heater
The Thermomate ES250B provides 2.5 gallons of hot water, which is a practical mid-size step up from the Eemax’s 1.5 gallons. It still uses a standard 120V outlet, ensuring easy compatibility with existing wiring. The dimensions are 13.2 by 13.6 by 18.9 inches, making it taller and slightly wider than the Eemax. You should pick this alternative if you frequently run out of hot water with the smaller unit but cannot accommodate a larger tank. It offers more reserve capacity for single-sink applications while maintaining the simplicity of a plug-in installation.
Camplux 1.32-Gallon Under-Sink Mini-Tank Water Heater
The Camplux ME15B is a 1.32-gallon unit very similar in capacity to the Eemax but with a different physical shape. It measures 11.4 by 11.4 by 9.7 inches and weighs 11 pounds. Like the Eemax, it runs on 120V power, making it a straightforward replacement for standard outlets. This model is ideal if you need a compact solution for a single sink but prefer a slightly different footprint. It offers comparable point-of-use performance with a focus on basic safety and space efficiency. Choose this if you want a reliable, small-capacity heater that fits into tight under-sink areas.
WINTEMP 13.8kW Electric Tankless Water Heater
The WINTEMP WN13 is a high-power tankless heater with a 13.8kW output. It is designed for high flow rates, making it suitable for showers or multiple sinks in mild climates. Unlike the Eemax, it requires a 240V electrical connection, which limits its installation options. The unit measures 9.7 by 9.7 by 14.1 inches and weighs 9.85 pounds. You should choose this model if you have strong electrical capacity and need instant hot water without storage limitations. It provides superior performance for high-demand applications but requires professional installation due to the higher voltage and power requirements.
