Works Perfectly
Size: 2.5 Gallon
Love this little hot water heater. My kitchen sink used to take 10+ minutes to get hot water, if at all. Everywhere else in the house would get it under 3 minutes. NOW, it is instant, within seconds the hot water is there. Makes doing dishes a breeze now and not wasting tons of water hoping to get hot water and it staying hot. I think I have an issue with a mixing valve in the wall that was causing my problem. I decided to try this before having my newly remodeled kitchen torn apart to solve the issue. Highly recommend.

Practical solution
Size: 2.5 Gallon
I searched for a long time and finally found it—this water heater plugs straight into a regular outlet, which made the whole setup so much easier. It works great, and it's super convenient not to have to deal with complicated wiring. The digital display is clear, the temperature adjusts easily, and the water heats up quickly. Highly recommend to anyone looking for a practical solution under the sink!

Nice
Size: 2.5 Gallon
Wanted to use this for my stock tank, but electric is too expensive. I need the propane option.

Nice for mobile food vendor/ camper
Size: 2.5 Gallon
Great small water heated for directly heating at the sink. Super easy to attach the water lines and plug in. A little deeper than anticipated. But works well for the amount of water needed in our small camping setup.

Great little water heater
Size: 2.5 Gallon
This 2.5-gallon water heater is compact and works great under my sink. The 1500W heating element provides hot water quickly and consistently. Installation was straightforward, and the included relief valve was helpful. I like the adjustable thermostat and LED digital display for easy temperature control. The mini-tank design is perfect for point-of-use hot water without wasting water.
