NEW Ariston GL2.5S & GL4S Mini Tank Heaters

Designed by the world's leading point-of-use water heater manufacturer, the New Ariston GLS series combines Italian design and state of the art features including glass-lined tanks, a 6-year warranty and highest recovery time.

Installing an Ariston electric mini-tank water heater under the sink puts hot water right where you need it - at the point of use. Lightweight and compact and also the Ariston mini tank heaters are great for those long hot water runs from your tank heater or tankless heater and will shorten the wait time for hot water.

The New Ariston GL2.5S mini-tank electric water heater stores 2.5 gallons of hot water.

The New Ariston GL4S mini-tank electric water heater stores 4 gallons of hot water.


Please note: The New Ariston GL2.5S is not the direct replacement for the Ariston GL2.5 as the Ariston Gl2.5S is 10 3/4" in depth and the older Ariston GL2.5 was 10 1/4" deep.  The new Ariston GL4S is not the direct replacement for the Ariston GL4 as the GL4S is 13 1/2" in depth and the older Gl4 was 12 1/4" deep.  The replacement parts for the new Ariston GL2.5S and the GL4S will not work for the older GL2.5 and GL4 mini tank heaters.

The new Ariston GL2.5S & GL4S models have many new improvements since they have been upgraded.  The mini tanks have a new temperature adjustment knob on the front of the unit to raise and lower the temperature from 65 Deg F to 145 Deg F.  On the older models you would have to remove the blue oval cover to access the temperature control knob.

The Ariston GL2.5S & GL4S models have a new improved thermostat that features a new sensing probe that is attached to the thermostat and inserts into the cavity of the new element so the heater can adjust temperatures quicker and maintain a more consistent heat.

The new Ariston GL6+S can either be hard wired to an independent breaker or wired to a power cord with 3 pronged plug.  Globaltowne has a 6' power cord in stock for the GL6+S.

Ariston GL6+ Mounting Options

The Ariston GL6+ mini-tank water heater has two mounting options: the GL6PLUS can be mounted either vertically or horizontally.

In contrast, the other two Ariston models -- the GL2.5 and the GL4 -- can only be mounted vertically.

When the Ariston GL6 PLUS is mounted vertically it holds 5.1 gallons of hot water. When it is mounted on its side it holds 7.1 gallons of hot water.

A common question regarding the Ariston GL6 is whether it can also be mounted on its back.

The answer is NO.

The T&P relief valve must always be on the top of the heater where the temperatures are hottest. With the heater on its back the T&P would be on the side, measuring a lower temperature.

Inside the heater, the cold water tube is longer than the hot water tube. This allows for "stratification" of water within the tank - cold water is delivered to the bottom of the tank and hot water (like hot air) rises. With the tank upright or on its side, the cold water is delivered to the lower portion of the tank and hot water is drawn off the top.

If the heater were placed on its back, cold water inlet and hot water outlet would be at the same level. The water at the top of the tank would be nice and hot, but you'd never be able to access it. The cold water would practically flow right through to the hot water side and result in lukewarm water at best.
