Who makes 'em? Can we pump the water back into the hot water faucet?

Don't remember who makes them... I remember seeing an ad for them a couple
of years ago when I was looking for another an air-conditioner that was
powered by an engine instead of electricity... The one I saw expected to
dump the water back into the drain... Basically, instead of using air to
cool the compressor and such, it used water and dumped the water
elsewhere... Kind of a miniature version of the geothermal heat pumps that I
had in my previous house, I guess... If so, then the water coming out is not
necessarily warm enough for showers and such, but might be acceptable as the
source of the 'cold' water for your hot water heater... Of course, you
would have to figure out something with regards to the pressure since I do
not believe that there is a water pump in the unit (i.e. it only relies on
the cold water inlet pressure to move it through the system)... As such,
since the hot water faucet is at the same pressure as the cold water faucet,
it wouldn't go anywhere...
