GE Smartwater Heater/Cooler DIY

[borillion_star]

Anybody know if one of those Tankless Office Water coolers made by GE that does both hot and cold water is enough for a 500 Gal tanks needs? I have not measured temps but the water coming out of it is frigid, the water out of it fogs up the glass straight out of the thing. And the hot water is hot enough to scald.

The one Im looking at modding looks like this:

Inside it looks to have no pumps or any other parts just basic gravity fed plumbing.


What're your guys opinions? :hmm2: :hmm5:

I wouldn't use it for saltwater since it has either copper or stainless coils inside. You definitely don't want copper and only certain stainless grades are saltwater safe.

I have an article with just about everthing you need to know

Bean, you have way too much time on your hands!:beer:

those things i think can only cool like a liter of water at a shot then it take 15 min to cool another liter,, so cooling 500 gal.....i dont think so.
i think those things are thermo electric too. it would be like putting an IceProbe in your big tank

Im really just researching, Im gonna take it apart and look inside first along with piping couple gallons of water through it and monitor the temperature.

Actually Ill run the total 500 gallon volume of water I make up, It burns up and I lost $20 not $1000 as a test run, no fish no tank, nothing to loose.

How are you going to run it through the unit? Check the materials first as most metals are not compatible with saltwater and plastics are horrible at heat transfer.

Even if it does work, which I think it will take a LOOONNGGG time to make any changes in temperature the unit will not last long in my opinion as the unit is not made to deal with that much gallon-age. 500G's is a lot.

It this any good its a Glycol/Water Chiller used for cooling lasers, my uncle told me I could have it for $700. Anyone seen one of these? Its a 1/2 hp.

 

[2_zoa]

WOW ... I have not seen the ones on the lasers at work yet, but I have seen the glycol units at breweries for the fermentation tanks. I would have to say that they are great units but......... I don't think that they have a place in the hobby as you would have to try to isolate the unit somehow and the only way I can think of is to put a titanium coil on it so the glycol is pumped through the coil cooling the water mass around it.

 

[AZDesertRat]

Breweries!!! Now you are talking my language:beer:

 

[borillion_star]

It does water also in place of glycol, is it worth the 700 to try it out? LOL

 

[2_zoa]

However just noticing that you have a 540 gallon tank in the works (WOW)I think I would try to incorporate it into the design cause these are designed to keep lots of heat at bay. I am sure you know that the best contact metal is titanium.(I think)



Sorry for the not so sure of myself as the whiskey is kicking in LOL.

Yea but what is the materisl that the unit uses? Copper, stainless, Brass (being a laser cooler)ect.

 

[2_zoa]

?????materisl??????

Told ya. darn whiskey

 

[borillion_star]

thats the problem, Im not sure he told me its safe for saltwater but I dont think he knows for sure, if you look at the 3rd and fourth pics it has an inlet pipe and and outlet that are rubber, looks like there is copper piping inside (LEFT LAST PIC), but I dont know what they are to, the look too small to me for the water tho, Im not sure but the price of a 1/2 hr aquarium chiller at almost $2K makes $700 very very appealing.

 

[borillion_star]

Suppose the thing does have some copper in the machine could I run a closed loop of a concentrated glycol into a thin walled PVC pipe and then use it to cool the tank, that way the copper is kept out of the loop?
