Water cooler parts?

[sixbennetts]

We all see them. Some have them in our homes. They run on 110 VAC. They take room temperature water from a big upside down clear plastic jug and turn it into VERY cold or VERY hot water, right?

Anybody ever crack one open, strip the parts, and make an in-vehicle water heater/cooler that'll run off an inverter? It would even run off shore power when at a campground.

Hmmm.....

heres one...at wally world...might be worth it for a tinkerer to pick one of these or something like it up and play around with it. all you would need is a good tank and pump and see where this might go....interesting to say the least

Well, I was thinking gravity feed from a Scepter on the wall. No pump needed. Hot Water for dishes. Cold drink on demand.

I was in the one at the office not too long ago, but not too deep. There's a metal bowl/ring and coolant flows through the outside. If there's not enough water it will ice up. It's very much like a mini fridge save the heat exchanging surface isn't the back of the fridge so much as the outside of the metal bowl. Flimsy construction to boot (at least that one).

Ok, I was just curious if the tinkerers had tried it. Think they're all made the same way?
