1. Ever since we moved into our new house my wife has complained about how long it took the hot water to get to the kitchen sink from the hot water heater in the garage. Since installing the Ariston GL 4, she has been ecstatic!! Hot water is instant. It is such a pleasure not to have her complain about our former water problem. Even when I am “forced” to do the dishes, I can’t complain about our lack of hot H2O. Installation was easy except for the ill-fitting two top fittings. They will accept the hose extentions (hardware store), but you must be firm and patient. It took away alot of our storage space beneath the sink, but it was worth it.
2. If your living in a place like mine where your hot water heater is a long way from the kitchen sink, then you are probably going crazy like I was waiting and waiting for the hot water to finally get to the faucet. There are technical ways to remedy this, but they involve a lot of plumbing, auxiliary pumps, and ripping half your house apart. Since I rent, I was thinking that the landlord wouldn’t take to kindly to this idea. So I started casting about for a better solution.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.

   So you may be thinking: Yeah. This all looks good in theory, but does it really work? I have to admit I was skeptical at first, but I have to tell you that this is one of those rare times when an idea I have actually works better than imagined. I’ve done small loads and big. The hot water is right there (immediately!) when you need it. And for all practical purposes it appears to be an infinite supply. I’ve had it in now for about 3 weeks and marvel each time I go to wash out a dish or two. Incredible! Don.

3. A lot of the reviews cite this product for use in addition to their water heaters for added hot water. However, if you are flat broke, without money to buy propane/gas or the electricity to run an electric water heater, then this is for you! We went three years with no hot water, having to heat it in canners on top of the stove and then carry it to the destination. With this heater we have plenty of hot water to wash dishes, wash your hands, whatever you need! When it runs out of water it takes about 30 min to heat again, but when we’re just using it like you normally would throughout the day, we never run out of hot water. Now, in the winter when someone wants to take a bath, we heat one 4 gallon canner of water and then run the 4 gallons from the heater and get a piping hot bath! Since getting this for Christmas, we have not noticed any change in our electric bill. In the summer I think that the heater alone provide enough water for a bath (doesn’t need to be as hot). We are even considering getting another one of these to use in the winter.
   Okay, so the temperature is hard to adjust, I did it once (turned it to high) and I don’t see why I ever need to adjust it again? To save electricity, when we’re not home or at night, it has a on/off switch in the red bubble on the front that I just flip off. So instead of adjusting the temp (like you would on a regular water heater) to save energy, just turn the thing off!
   Well worth the investment! Good luck!
