Hey doofus (heh heh),

I take it you don't like to conduct a simple search before posting...

InSinkErator Instant Hot Water Dispenser with Stainless Steel Tank (Google is your friend.)

Personally, I think they're a waste of money and energy (who needs hot water at 3 AM!). Think about it: why spend the money to run an appliance 365/24/7 -- which you pretty much have to do when you choose to install an undercounter hot water dispenser -- when you can buy something that is MUCH cheaper to purchase, MUCH cheaper to operate, can be put away in a cupboard when not in use, and doesn't really clutter up a counter anymore than a small toaster.

That's why I prefer these:

Zojirushi COUNTERTOP Hot Water Dispenser

The choice is yours...

I take it you don't like to conduct a simple search before posting...

One of the attractions of this site so far, has been the general civility of the tone and absence of petty lecturing. I did mention having searched in my original post, and I did explain, why I didn't like the result. That you found something else is terrific and appreciated. The lecturing is not... Personally, I think they're a waste of money and energy (who needs hot water at 3 AM!).

When one is down with a flu, hot water at 3am may be quite useful, for example. Another example is when  like right now  one is feeding their newborn and needs hot water both for tea for themselves and to quickly sterilize the pacifier...

I also disagree with your assertion, that these units are necessarily a waste of energy  they can be made well insulated (like Zojirushi). A good thermos can keep a drink scolding hot for hours. A heating element keeping it that way all the time needn't be very powerful at all. Most people still keep the 60-100 gallon tanks for their hot-water needs. Until very recently this was not considered "wasteful" at all. So, I don't think a 3/4 gallon tank would qualify for the label either.

You may like the Zojirushi, but it is neither built-in, nor stainless steel inside (where it matters).

You can pour a bottle of water into a drip coffee maker and have hot water in seconds. Filtered even! And it's super cheap. :)

Doofus,
Don't dismiss the Zo so quickly. I have one too and I love it. I don't have that particular model but it works wonderfully. If you want something built in, then the Insinkerator or little butler are your only options unless you purchase an espresso machine that also has a water dispenser. I have a semi-pro espresso maker and the water that comes out is boiling because it is what is used as part of the heat exchanger system. Any particular reason you want a stainless steel interior? The Zo has a smooth interior that is very easy to clean too. It has a descaling function and it also childproof. You need to press two buttons to dispense. The product is also relatively leak proof because I had one on its side for about thirty minutes without any leaks. The cord also detaches very quickly like the mac notebook magnet based cords in case the unit is pulled or yanked. I love my little Zo and only wish it was larger sometimes. It heats and holds the temperature for a long time. I had a power failure and still had boiling hot water 6hours after the power went out. I also have a Zo rice cooker and love that too. I will stop raving now!

Good luck!

After a few minutes searching, I found a few more build-in-able "appliances" that produce close to boiling water
Everhot / Bradford White Corp --- Instant Hot Water , Instant Chilled Water
Anapolis Filtered Water / Hot Tap Faucet
Calorah Instant Hot Water Dispenser/Heater from Westbrass
Kitchenaid Instant Hot Water Dispenser
Franke Instant Hot Water Dispenser
Bunn Instant Hot Water Dispenser

Used as keywords: instant hot-water dimensions -wind -software -hotspot . Did not use Dispenser or Stainless.

What I'd like is to get the dimensions of each tank since I have to keep it slim on its narrowest side.

Also, I'd like to find out how to buy separately
- tank
- pipe
- spout
- lever
This is to have more freedom to choose a spout and a lever we like.
It has to be built-in as "we" cannot stand more counter top clutter.

I'd be glad for any help.

p.s. At http://www.instanthotwater.co.nz/products.html there are a number of options (not available here), in case anyone wants to study the physics of heating and delivering "instant" hot water in various setups.

Doofus,

I went back and re-read your post, and the only searching you allude to is "Amazon lists plenty of such counter-top devices." Again, if you had done a simple search (like this), your question would've been easily answered.

I stand by my previous comments. If you feel you can justify the purchase and operation of a built-in hot water dispenser, go for it. I gave you a link to one of the best in the industry, and I promise I wont turn you in to some greenie witch-hunt group that targets wasteful energy hogs! ;-)

Don't dismiss the Zo so quickly. I have one too and I love it.

Yes, Zojirushis have their fans  one of my good friends among them  but we don't want to have plastic interior... Various plastics are found to be leaching something into the water once in a while, and the leaching is worse at higher temperatures. Ideally, the material would be glass (which also has superior thermo-insulating properties), actually, but stainless steel is acceptable.

I personally have been through 3 hot water dispensers - all insinkerator brands. The first had a metal handle which lifted to dispense. It was quite pleasing to look at and being part of the sink didn't take up counter space. The handle broke after only one-month of light use. Under warranty, it was repaired; broke again just after the warranty expired. We replaced the whole unit with the same brand, different handle (was black and had to turn it to dispense). I live in area with very hard water and I just recently took the whole unit out after about 7 years of infrequent use due to the fact that the water would taste funny. Probably if we'd been more diligent to dispense water every now & then this wouldn't have been the case. It worked properly otherwise and if we were more avid hot tea drinkers I would not hesitate to have one installed again. It did not use a large amount of electricity in my opinion.

I wanted to point out two things about the Insinkerator:
1. Only one of the three instant hot units come with a stainless tank. That model also includes the filtration system which I would recommend if you currently don't have a filtration system. The other units use Bronze tanks so be careful.
2. The Insinkerator only heats to close to 200F. The Zo heats to 208F (actually to 212F but it only holds at 208F).
3. The capacity of the Insinkerator is .66gals which is smaller than that 4L of 5L Zo units.
4. You can purchase handles for hot water dispenser systems from several sources apart from Insinkerator. Waterstone is a manufacturer that several people have purchased on the Kitchen Forum. They also have many styles in comparison to the Insinkerator branded units.

Good luck with your decision!
