We also offer replacement parts for Ariston mini-tank water heaters.



Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.

Frequently Asked Questions

Q. "Why do these mini tank heaters have on/off switches?"
A. The on/off switch serves a twofold purpose. First, by turning the power on to the unit by using the switch, rather than just by plugging the unit into the wall, you reduce the chance of having the unit turn on without being filled with water, which extends the life of the element. Second, an on/off switch allows a mini tank water heater to be turned off without completely uninstalling the unit. If you're facing the unit, the switch is located on the left side near the bottom and toward the back of the unit. A green light will turn on when the unit is plugged in and the switch is in the "on" position. Please note, the manufacturer states that the heater needs to be turned off AND unplugged if maintenance is needed.
