Chiller electricity cost calculation.

[A. Grandis]

Could you help me with that, if you know how to?
I just want to know about how much would be to run the chiller...

I know there must be lots of things to consider, but I need just a simple estimate.

Tank is a 75gal with 20gal sump.
6 bulb ATI PM for 10 hours.
Difference between room temp. and tank temp. now is about 7F.
I know that because the air conditioner is set at 72F 24/7 and the tank is +/-79F const.
I want to substitute the AC for the 1/5 JBJ chiller...

I've contacted JBJ but they don'y know how to calculate.

Thanks,
Grandis.

Is your tank even overheating at all? T5s impart little heat, and unless your tank temp is shooting over 82+, i would think a chiller is not even needed?

 

[A. Grandis]

Yep Jim, I need a chiller.
Without a chiller the temp can go up to 86F.
It did in the past, without the AC, when I had a fan and only a 4 bulb fixture.
I want to keep on the 78 - 79F.

with what we spend on our tanks a few dollers if that a month wont much matter

It will be less then 60$ a month if it runs 24/7...

Your missing way to many variables to predict a running cost...

But your probably talking in reality less then 10$......

Is your return pump in the water or is it ext. You could do away with alot of heat if its in the water.
You could also vent the hood with a small fan to get rid of some of the heat from the lights.

my 125 was running around 83 to 85 with an 8 bulb T5 set up with 2 96 watt PC bulbs also
they sit about 10" above the water in my canopy. the canopy is enclosed except for two 5" x 6" holes cut ay either end. i have a 10" (60CFM)vortex fan at one end drawing air in and 2 5" fans at the other end drawing air out. My tank now sits at 79/80 and I keep my a/c at 76 with no chiller
I have 4 26 watt CFL's on my ATS in my sump that are on at 7 off at midnite, my other lights are daylight on fom 8am until 3:30pm and actinics and purple on at 6:30 am off at 7pm,I alos have on 26 watt CFL on my fuge. I have an in sump mag 7 for return and a in sump 350 gph pump running my canister filter and the pump from my skimmer now running my fuge. I have a 10" fan blowing across my sump and a 6" fan blowing on my external pumps(2...1 - 3200 GPH mag drive and 1 - 1000 GPH quiet one) So with the right amount of air circulation you don't need a chiller,but i wonder if the fans use up more electricity then the 6 fans i have total running

I know. The number would be just to justify purchase of the chiller.

It will be less then 60$ a month if it runs 24/7...

Thanks very much!! I know about the variables and that's why I wanted only an estimate.

Is your return pump in the water or is it ext. You could do away with alot of heat if its in the water.
You could also vent the hood with a small fan to get rid of some of the heat from the lights.

All the possibilities for the cooling of the system were done before the set up.
There is no room for an external return pump. The hood is open. The house is closed and the AC fans will still be on but the aquarium's temperature won't be able to depend on it because sometimes the AC will be up to 76 - 78. Thanks!

Thanks! I know about the air circulation too. The house is closed and the evaporation can't be enhanced.

Anyone else with an $$ idea of the electricity?
