Water-Cooling Your Equipment

Does anybody water-cool any of their grow equipment? I was looking at a water-cooled co2 generator (http://www.plantlightinghydroponics.com/hydrogen-water-cooled-propane-co2-generator-p-2664.html). I hear normal CO2 generators usually raise temps about 10 degrees. It'd be nice to have just co2 no heat.

I know there's water cooled lights (well reflectors) as well. It would be awesome to have lights that didn't produce heat. How cool do water cooled lights run?

I guess I am just fishing for anyone's experiences with water-cooled equipment. Is it worth the extra headache? Cause I am not super thrilled with the idea of having another reservoir and a bunch of water rushing through the hoses in the over head of my grow.

i have that unit but the newer one theirs heat but less of it, it is prett good i have a private well so i run to waste so prally the best cooling the thing will ever get. i dont think the light hood are worth it because it can be 80-90 out and i can draw ambiet air not cooled thru my hoods and still touch the tops but the air has to be like 30 to be able to touch the glass so cooling the top does little to cool, well me be they work i dont know but u see wer i was going before i startd thinkin. and u need a huge res and chiller pain in the ass unless you have a private well.
