- You only need hot water for quick hand washing.
- You prefer a longer tank warranty for long-term reliability.

Capacity, Size, and Build Comparison
Capacity and Output
Thermomate offers a 6.5-gallon tank, while Electrolux provides only 1.5 gallons. This difference defines their use cases. The larger Thermomate unit holds enough hot water for a kitchen sink or small bathroom with multiple uses. You can run the faucet longer before the tank empties. The Electrolux 1.5-gallon model is strictly for single-faucet point-of-use applications. It refills slowly after each use. If you need hot water for handwashing at a guest bath or office sink, the smaller unit suffices. For any scenario requiring sustained flow, the Thermomate capacity is superior.
Physical Dimensions
Size matters when fitting these units under crowded sinks. The Electrolux measures 10.1 x 12.3 inches, making it significantly more compact. It fits easily into tight spaces where clearance is limited. The Thermomate is larger, measuring 17.7 x 17.7 x 14.6 inches. While still under-sink compatible, it requires more room. If your cabinet space is narrow or shallow, the Electrolux is the practical choice. Its smaller footprint allows installation in areas where the Thermomate would not fit. Check your available clearance before deciding.
Wattage and Power
Both units run on 120V power, but their wattage differs. The Thermomate operates at 1.44 kW. This higher wattage helps it recover heat faster than lower-wattage competitors. The Electrolux specifications do not list its wattage in the provided data. Without that number, you cannot directly compare heating speed based on power input alone. Both plug into standard outlets. The Thermomate draws 12 amps nominal current. Ensure your circuit can handle the load. For known heating power, Thermomate provides the clearer specification.
Temperature Control
Thermomate allows you to adjust the temperature between 50°F and 149°F. It includes three specific settings and a freeze mode to protect the tank in cold environments. This range gives you precise control over water heat levels. The Electrolux data does not specify its temperature range or control options. You cannot verify if it offers similar adjustability or freeze protection. If you need specific temperature settings or protection against freezing, the Thermomate features provide more certainty and utility.
Certifications and Warranty
Safety certifications and warranty terms vary between the brands. Electrolux is CSA certified and includes a 6-year tank warranty plus a 2-year electrical components warranty. This offers longer protection for your investment. Thermomate is UL Listed and provides a 3-year tank warranty with a 1-year parts warranty. While both meet safety standards, the Electrolux warranty period is significantly longer. If long-term coverage is a priority, the Electrolux terms are more favorable. The certification bodies differ, but both indicate compliance with safety standards.
Choose the Right Mini Tank For You
You need hot water for a small sink
The Electrolux model fits tight spaces with its 10.1 by 12.3 inch footprint. It holds 1.5 gallons of water, which is enough for a single bathroom or office sink. The compact size makes installation easy under most counters without taking up valuable storage room. You get reliable heat for quick tasks like washing hands or brushing teeth.
You want higher capacity for kitchen use
The Thermomate unit provides 6.5 gallons of stored hot water. This capacity supports a kitchen sink better than smaller tanks. You can run the dishwasher or wash dishes without waiting for the water to reheat. The 1.44 kW heating element works with standard 120V outlets. It delivers consistent hot water for multiple uses throughout the day.
You prioritize longer tank warranty coverage
Thermomate includes a 3-year limited warranty for the tank. This offers more protection than the Electrolux 6-year tank warranty but includes 1-year parts coverage. Both brands provide electrical component support. You get peace of mind with UL listed safety features. The glass-lined tank helps prevent corrosion and extends the service life of the unit for daily household use.

Frequently asked questions
Are Thermomate and Electrolux units truly tankless?
No. Both brands offer electric mini-tank storage heaters for under-sink use. They hold pre-heated water rather than heating it on demand. You get hot water instantly from the stored reserve, but the tank must recover heat after use. This design suits single-sink applications where continuous high-volume flow is not required.
Which brand offers a larger water capacity?
Thermomate provides a 6.5-gallon capacity with its ES model. Electrolux offers a smaller 1.5-gallon unit, model EES015. The larger Thermomate tank holds more hot water, making it better for kitchens or bathrooms needing multiple uses. The smaller Electrolux unit fits tighter spaces but provides less total hot water per cycle.
Do both brands require a 240V electrical connection?
No. Both the Thermomate 6.5-gallon unit and the Electrolux 1.5-gallon heater operate on 120V power. You can install them using standard household circuits without upgrading your electrical panel. This makes both options easier to integrate into existing under-sink setups compared to higher-voltage tankless systems.
Which model is more compact for tight spaces?
The Electrolux EES015 is more compact. It measures 10.1 inches wide, 10.1 inches long, and 12.3 inches high. The Thermomate ES model is larger, measuring 14.6 inches wide, 17.7 inches long, and 21.2 inches high. If your cabinet space is very limited, the Electrolux footprint is the better fit.
Can I use the Thermomate unit for a bathroom sink?
Yes. The Thermomate 6.5-gallon model is designed for under-sink use and can serve a single sink or small bathroom. Its larger capacity ensures you have enough hot water for handwashing or brushing teeth. It delivers reliable point-of-use heat for these specific applications.
What colors are available for these mini tanks?
The Thermomate ES model comes in white and blue finishes. The Electrolux EES015 listing specifies the 1.5-gallon capacity in its color description field. Both units are designed to blend into standard under-cabinet environments. Check the specific listing for the exact finish available at the time of purchase.
Which brand is heavier and requires more floor support?
The Thermomate unit is heavier. It weighs 26.5 pounds due to its 6.5-gallon capacity. The Electrolux model is lighter because it holds only 1.5 gallons. Ensure your under-sink shelf or cabinet floor can support the weight of the filled Thermomate tank. Both units are designed for standard cabinet installation.
