Ariston Water Heaters


With the cost of electricity steadily rising, Ariston's point-of-use water heaters are an excellent choice. By choosing one of these compact units, you can get 2.5 to 8 gallons of hot water when you need it - a half cup or a whole gallon at a time - which is great for making a cup of tea, or starting dinner without having to wait for the water to boil. Let PlumbingSupply.com® be your source for these and many Ariston parts.

Frequently Asked Questions

Q. "Can any of the Ariston models be used on the hot side of the plumbing? My hot water heater takes a minute or two to reach several sinks, wasting time and water. I want to put a small tanked water heater in-line on the hot side."
A. Yes, any of the Ariston models can be used for that application.

Q. "Do the Ariston heaters come with power cords?"
A. Yes, all of these Ariston compact water heaters come with power cords.

Q. "Do these Ariston water heaters have drain valves?"
A. No. These units are small enough to disconnect and drain into a sink if desired.

Q. "The Ariston products specify the recovery rate - 'temp. rise' based on the GPH; what do you mean by this?"
A. The recovery rate is the amount of water that the heating source can raise the temperature 90 degrees in 1-hour. A 1500 watt element can raise 6.8 gallons of water 90°F in 1-hour; if you turned on a GL8Ti, 7-gallon water heater with 45°F water in it, it would take just over an hour to heat the water to 135°F.
