  • Compact, Efficient, and Reliable Mini Water Heater
Style: 2.5 Gallon-G
I recently purchased the Westinghouse Electric Mini Tank Water Heater, and it has been an absolute game-changer! This compact unit fits perfectly in tight spaces and provides hot water instantly, making it ideal for our needs. The build quality is impressive, and it heats up quickly without consuming too much energy. Installation was straightforward, and the included mounting brackets made it even easier. The tank's capacity is just right for small spaces, and it consistently delivers hot water without any fluctuations. We installed it under the sink in our clinic, and it’s been working flawlessly since day one. No more waiting for hot water! The stainless steel construction also gives me confidence that it will last for years. Highly recommend this mini tank water heater for anyone needing a compact, efficient, and reliable solution. Worth every penny! ... show more

  • mini water heater
Style: 2.5 Gallon-G
This water heater is everything we expected it to be. with the ability to get hotter than we need, the thermostat didn't need to be maxed out. The 12 amp draw was kind enough to not kick our breaker off. With 2.5 gallons of hot water, there is plenty of heated water on hand for bathroom tasks.

  • Great little 2.5 gal heater.
Style: 2.5 Gallon-G
I installed under the master bath sink in my home. Not easy to install, most homeowners should use a plumber. I was lucky, I had a 110 V recepticler next to the cabinet. The unit works flawlessly. You will have 2.5 gal of instant hot water and by the time that runs out, you will have the house supply coming out. ... show more

  • Great for coffee cart!
Bought this for a coffee cart to use for hand washing, so far so good! Heats up quick. Saves a good deal of space. Easy to install. Just note you will need 1/2 connectors, and the sink ones you get at Home Depot are a little to shallow for these. I found some at a specialized plumbing store, but you can find them here on amazon. I wish they gave a “bought these together” option. ... show more
