Rated 5.0 out of 5.0 by sdfgs Excellent product -- great for condos
Often in my condo it takes a long time for hot water to run. This product fits easily under a standard counter and works quite well. I would recommend it, as it's small enough to be unobtrusive.

Rated 5.0 out of 5.0 by Daddo Great Little Water Heater
Installed under the counter for the source of an instant hot water tap. Used quick-connect fittings so removing the lines to drain it & change the element when necessary will be quite simple (it has no drain valve). Will install one in a bathroom remodel that's at the other end of the house from the water heater so no waiting for a hot shower.

Rated 5.0 out of 5.0 by BillNarvaez Emergency hot water heater
My whole house electric on demand hot water heater burnt out. Went to Home Depot to look for a new heater or a hold over. Found the artisan 4s. I took a chance because I needed hot water immediately. was a simple hook-up. Used Shark bite and Pex pipe (also great products). I wasn't sure how long the 4 gallons would last taking a shower so I experimented. Regular shower head - water ran until hot -jumped in and got wet - shut off water - shampooed and washed - turned on water to rinse - turned off and used conditioner - turned back on and rinsed - water just started to get cold. Installed a water saver shower head - ran water the entire time I washed and rinsed and still had hot water to spare. My kids hate it but, it gets them out of the shower faster which means a savings on water and electric. one half hour or more showers are common at my house. I would like to keep it installed just for that reason. As long as you have a 120 20 amp receptacle, your in business.

Rated 3.0 out of 5.0 by DaddyMonster This is a replacement.
It was easy to install because I was replacing one that failed. It was 4 1/2 years old. I hope this one last longer.

Rated 5.0 out of 5.0 by appledude Great water heater, needs service every 6 months
I have used this GL4 for 8 years now, very durable, no leaks. I learned very quickly that our water in San Diego is so hard that the GL4 needs cleaning every 6 months, which the instructions tell you how to do with vinegar and baking soda. The anode rod needs replacing at this time, but it is cheap, and I buy them 3 at a time from the suggested supplier. I suspect a lot of the problems people have reported is due to not cleaning the unit. I installed mine with flexible stainless hoses, making sure they are rated for hot water. I installed galvanized pipe closer to the water heater, as the temp seems to break down the rubber inside the stainless hoses in a couple of years if connected directly to the water heater.
I bought a used small Rigid wet-dry vac, the type you can carry - to make cleanout easier. After I have cleaned the tank and heating element, I put a bit of vinegar inside the almost clean tank, and flush it with water. Then after hook it up I run the sink faucet without the aerator attached to flush the last bit of vinegar water and crud from the heater.
To me, servicing every 6 months is a small price for the luxury of really nice hot water for my kitchen sink, dishwasher, and front load washer. I can't run my dishwasher and washing machine at the same time (unless running the washer on cold cycle), but who cares?
I read some complaints about not enough water for showering - this is a fault of the contractors who put these in for this purpose, this is a 4 gallon water heater, enough for hand washing, and small tasks such as appliances that use some hot water, then give the water heater time to reheat before drawing on it again. It will not do the job of a 20 or 30 gallon water heater, it is only 4 gallons. There are instant water heaters out there, but this is not one of them, nor is it as expensive.
I also installed mine on the countertop, and placed it on a rubbermaid dish strainer mat, so when I service the unit, or if it leaks - the water gets directed to the sink. Makes things so much easier, though it has never leaked.
I like the styling of the unit, and love the on/off switch being easily accessible. I turn the unit off when I leave, and on when I come home. During the hot summer months I leave it off until I really need it.
Over the years a bit of insulation may have came out of where a heavy power cord goes into the body of the heater - when I service it, I may have gotten this area bit too wet the last 2 times. I have had to leave the faceplate off a day or so for it to dry, otherwise it kicks the GFI outlet off nearby. I will contact Ariston to see if I need to put something back in to seal this small gap again.

Rated 2.0 out of 5.0 by VGVG1 Does not last long unless you have soft water
We purchased this point-of-use water heater because it used to take a very long time to get hot water in the kitchen sink. It was a very nice solution and we were very happy with it. However, the tank started to leak after less than 2 years. We called the company and they explained that with hard water (which is pretty much the case in the whole country!), they recommend changing the anode every year to prevent degradation of the tank. Well that was easier said than done! They sent us a replacement tank since it was under warranty, but process of changing the anode every year is costly and difficult. Anyway, we got rid of the whole thing, but it good while it lasted.

Rated 3.0 out of 5.0 by JTinTX Does not last long
This unit heats fast and provides a good amount of water for light jobs. We bought it to replace a tankless natural gas water heater that failed due to cold air coming down the flu pipe causing the tankless heater to freeze and rupture. We thought that having a small electric unit like this would be more reliable but still sufficient for our sink water and dishwasher. It works fine for that and we rarely run out of hot water. We also love the instant hot water since it could not be any closer to the faucet.
However after 4 years we've had to replace this Ariston unit twice due to leaking tanks ( we're on number 3 now) so it is NOT hassle free. Not sure on what planet will the tank last 6 years per the warranty. I've had water damage twice now due flooding. Although not called for in the instructions, this time I've placed the unit in a water heater pan with a drain!
