The new Ariston GL4S has many new improvements over the older Ariston GL4. The Ariston GL4 has 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 while on the older Ariston GL4 you would have had to remove the blue oval cover to access the temperature control knob.
The Ariston GL4S also has 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.

I have this hooked up inline with a gas tankless water heater and I wanted to know how much this new heater was costing me in electricity, so I hooked up a meter to check it out for a few weeks. It turns out that, with our normal usage, it uses just about 5 KWH/week - which works out to about $2/month in our area.
Before this heater, we had to run a full 2 gallons of water down the drain before getting hot water to the sink - which was both a big pain and somewhat wasteful. With this 4 gallon heater, we basically have an instant and endless supply of hot water at the sink since the hot water from the main tankless unit arrives before the water cools too noticeably. I've also noticed that it seems to heat water on it's own very quickly.
The biggest problem with this water heater is how much of a pain it is to set the thermostat. You basically have to remove 3 panels and then turn a dial that isn't labeled at all. In order to get it set to the same temperature as my main water heater, I ended up using an instant-read thermometer and moving the thermostat dial as I filled the tank with cold water and let it reheat it to the set temp. The process took a while, but I shouldn't have to do that again.
Overall, I'm very pleased with the purchase and would recommend this water heater.
Edit: It is now February, 2010 and this water heater has been installed for almost 2 years. It is still working perfectly and I haven't had to mess with it at all since the initial installation.Read more ›
Two years later, I asked the plumber to put the exact same water tank into my house on the other tankless water heater. Instead, he installed this one by Ariston (Bosch). After I saw what he did, I told him this wasn't the same brand, but he assured me that this was far better. It was *NOT* better.
From the very beginning, the thermostat circuit kept triggering and shutting off because it said the water was too hot. Even when I turned it down to a very low temperature, it kept triggering. I would have to run down the basement and reset the tank. After many months of this and calls to the plumber, he told me to call their customer service line. Ariston (owned by Bosch) sent me a new thermostat and told me to install it. I installed it with some difficulty because the instructions on how to do this were terribile.
It fixed the problem for about 6 months, then it started triggering again. At first occasionally. Now it triggers every day. I get lots of exercise running the stairs. I assure you that I'm monkeying with this thing so much that it doesn't have any dust or spider webs on it. It's squeaky clean.
I called tech support and asked for a new thermostat again. They told me that my warranty expired and I was on my own. The guy on the phone, Scott, was rude and condescending.Read more ›
That's when I came up with the idea of putting a little water heater as close to the kitchen faucet as possible. With this, the hot water is right there where you need it. No waiting and wasting a lot of water while running the faucet so that a half mile of plumbing warms up.
'Only problem is a tiny tank has very limited capacity. If you're only washing a dish or two like me, then no problem. But if you wash a sink full of dishes, it will quickly run out.
But the trick is to hook this little heater right in line with the hot water supplied from the big tank. As you draw hot water, cold water will go into the small heater, but only for a gallon or two. Then as you continue to draw hot water, the small heater now has hot water being supplied to it, so the hot water just keeps on coming.
I checked around with local suppliers and found small hot water heaters, but most were kinda short and stubby and wouldn't fit under the sink well at all. But I stumbled upon this neat deal from Ariston. It's a nice clean design, well insulated, and fits under the sink extremely well. I also felt that the price was very reasonable considering how nice it is. The funny thing is, it seems to be specifically designed for exactly the idea I had in mind. It was a snap to install.Read more ›

Really pretty to look at. Installed fairly easily. If only it made hot water it would be perfect. It does make the water lukewarm sometimes. But usually it's cold. Read morePublished 2 days ago by Stan Delk
