Just got the coolest chiller!

fliger...deal or no deal. NO DEAL!

thx switch...nothing ancient about a baron...Bo/Baron airframe = uber. after 4000 hours mine gets recycled into 1 liter Coke bottles.
 
is the basement always cooler then the house, does it or the house change temp. faster or to a greater degree? if so i can see you getting greater swings because of the difference in temp., regardless of where the peltech is. you could try moving the unit upstairs and see what happens. i would also think about insulating your sump.
 
ive been trying to order the 400 to no avail.

its like my money is no good.

would anyone like to have $1200.00 of my money? ill paypal it to you, free.
 
lol after reading the first page of this thread i was like this thing must be amazing and when he said it was a peltier chiller but more expensive i was thinking maybe 400-500 and then i did some searching and found that they go for quite a bit of change
they sound AWESOME and if i had the money, it would be the first thing on my list
you guys must have money to throw around...wanna throw it to me? lol jk

throwing money is fun.
 
As long as you remember the efficiency curve of a peltier. There is a reason that we don't see this in everything instead of freon.

The bottom line here is that peltier junction cooling devices are nowhere near as efficient as phase change cooling technology.

The advantage of the peltier units is their simple installation, small footprint, quiet operation and minimal mechanical wear parts (just a fan). Just do not be fooled into thinking your saving money on electricity. If you were to purchase a properly sized phase change chiller, it would be significantly more efficient.

Hey man, did you get it functioning better?

I'd say there are a few other cool things, I love the fact that it heats & cools with the same element and on the same controller. You set one temp and when the tank exceeds that temp it chills, when it dips below that temp it heats. They never fight one another and you don't have to put in a gap. And there is only one plug.

Its also extremely silent and so small that you have many more options where to put it. I move it around all the time.

As far as maintenance - there really is not any. Wipe the dust off occasionally. The fans are the only moving parts. No freon charges or worrying about when you will run out. No compressor.

On electricity - IIRC it does save electricity. Probably not a ton, and not enough to make a big difference. I had this on a kill-a-watt for a while when I first hooked it up. Back on the first few pages I posted the numbers but really had no reference. I know what my 1/3HP chiller drew while it was on (a lot) but it wasn't on all the time. This chiller/heater is on all the time but the controller regulates the multiple fans & the fan speeds so it can go to just a few watts on up. I can not remember what that was though.

I thought about getting a larger one for my new tank (210G) but I'm going to try to make this work in conjuction with a Prolifix fan. I'll hook the kill-a-watt meter up again and post results.
 
Hey Fliger,

I read all thru this thread and having never been exposed to a Peltier or read anything, they seem very interesting. I'm sure I saw it a while back but how big is the tank that this is running on? I talked to one of my lfs owners whose opinion I respect most of the time and he mentioned that on a 150 gallon tank it's almost not worth it so that's why I was curious about your tank size. I see you're thinking of using on your 210.

One other question about power consumption. Have you left the kill-a-watt plugged in for a 24 hour period to see how many kWH it really uses in the course of a typical day? Again, very interesting thread even if the price of these is prevents me from trying one.
 
ok i started with a mj400 on my geo 400. didnt have enough power to push the water thru the unit. the mj400 is 5w at 100gph.

switched to mj1200. plenty of flow, 395gph?. but it is 20w and it raised my sump temp about 2-3 degrees so my Geo started working when it didnt have to...so.

switched to mj900, 300gph at 8.5 watts, perfect, flows fine, no additional heat.

just an observation.
 
i was just curious, but do you have a flow meter on your mj's?
cause on sites that sell them say the mj900 is 230 gph and the 12 is 295 gph
just curious if all the sites are wrong
also how small is your sump to increase the temp 2-3 degrees from a small ph?
that doesnt sound right
 
oops my bad, i was off by a hundred...was going by memory, a sad one at that.

the mj1200 pumps only a little more but at a huge watt increase over the 900.

sump is about 15 gallons. i sat there and watched the temp increase, didnt take long. i had all 3 ph's in hand and tested all 3 at the same time. the mj1200 runs hot.
 
hey there fliger - so are you still running the geotronic? would you buy it again? i'm considering a pair for a large system... but man, they are not cheap! thanks for any insights!
 
Didn't read the whole thread just wanted to know what the cost of the chiller was when you bought it.
 
i'm looking at a 400g system (270 display) with fans throughout the sump. i think i'll only need to pull it down about 2-4 degrees. will i need a pair of 900's? (crazy expensive!)
 
You might want to ask the folks at Peltech but I don' t know if you can put two on the same system. Since they heat and cool they might work against each other unless they were perfectly synced. If you only need that much pull down you might be fine with fans and one 900.
 
one benefit that I have found that doesn't get talked about is that with a stable temp and no fans blowing on the tank or sump you get very little evaporation. my tank is rimless and near my living room and there is very little odor because I don't have a lot of evap.
 
I read through part of this thread and I too have my doubts about pelteir coolers.

Testing the efficiency of this device is easy. I can do the test if someone wants to loan me one of these devices for a few days.

Hook up a logging power meter to the device between AC 110V and the device.
Set room temp to 90 F
Ensure the water is also at 90F
Set chiller for 80
define water volume as 80 gallon.
you want to see how long the water takes to reach 80F and how much power it consumes doing it.

multiply power by amount of time (hrs). Should give you watt hours.

Repeat experiment on a regular chiller. We should be getting these kind of spec sheets with the chillers we buy. NOT rated max power.
 
From a user point of view, I have the 400 model, and it's dead-on accurate.

Has been keeping my 120g reef tank steady for a full year now.
