Has going water cooled saved you any cash on your electricity bill?

I think the idea with the Coolerado would be to put it outside your room, like a chiller, and blow the cold air in. This will dilute the CO2 in the room a bit, but would still have no exhaust (or need for it.) Just pumping in cold air from outside, just takes a hole in the wall/window board etc and some creative camouflage. It would probably work well in my situation, but definitely not for everyone. The guy from Blue star emailed and asked where I live, but he's making me a quote! woot!

what? when you pump in air into the room it has to go somewhere. it will create positive pressure so you need an exhaust of some sort. so coolerado = no sealed room

Well, I figured if the whole unit draws just 600W at 120V, it just can't be some 2600 CFM fan, probably closer to 400cfm at that draw, not enouh to pressurize my building much I'm sure. I wonder if it could support one of these vent tubes for distribution:

But, I figure for the power savings alone even a pressurized room is not a deal breaker for me, I'd figure out how to make it work. In a smaller room no I don't think it would be good, but for bigger grows, 6 ton at 600W! Crazy not to try and use one somehow.

Geo, where did you find your exchangers and how do you size them for a specific application? Is there a calculator that shows water temp vs. BTU of an exchanger?

I can honestly tell you I have no idea how one would size it to a grow. I think I picked up mine about 10 years ago or so at a surplus auction with a ton of other things. I believe it was originally designed to cool telecom equipment.

If it was sized correctly my A/C wouldn't run at ALL ;).

Your best bet on sizing a heat exchanger is to give your specs to a manufacturer. Say something like "hey, I'm spending a bundle on A/C right now, the equipment in my (factory, bar, workshop, secret underground missile base, etc) puts out around XXX watts (or BTU, it's easy to convert) of heat. What would you recommend for my application.

Manufacturers WANT to sell their product. So if you ask, they're likely to be very helpful.

Yep thats pretty much exactly what I said to blue star air, lol. Still waiting on my quote though, I will post as soon as I hear.

Im told a 3 fan will adequately cool 7 lights in winter with good cold tap water... but in summer when the water gets warm here it will struggle to do 2-3....

Yeah I would buy that. I think a 2HP chiller and a 55 gallon insulated res would probably keep those temps reaal stable year round, as long as they are kept out of the sun.

man, I'm running a 600 watt and 8000 btu ac in one room and a 1000 watt and a 5000 btu in the other room. Both are air cooled but sucking 85* air. Water cooling has got to be able to save me some cash. My ac's are running almost full time and take as much or more juice then my darn lights and are running nearly 24/7!

Ok just got my first quote: A Coolerado M50 (5-ton) costs $5K plus tax. Damn! But, I figure I don't need to upgrade my power circuit (a $2K job) to run one, and with the monthly savings (I figure $90 a month over a regular 3 ton AC, could be more) it pays for itself in about 1.5 years or so. I'll see if I can pick one up this winter for cheap and install it myself.
