How much heat does your equipment generate?

[saltyhog]

There is one of those pesky thermodynamic things again. I have lost a/c in the heat of the summer for days at a time (we lose power a lot), and as long as I can keep water circulating between the basement and the DT, it seems as though the tank stays below 80. Fans help, and the basement has to be helping cool the tank.

How hot does it get there in the summer?

We have mid 90's to 100 for most of the summer (92 is the high today) and high humidity. That really limits our evaporation related cooling. I worry more about over heating with a summer time power outage than winter time since we have a gas fireplace/heater in the room with the tank.

Usually stays below 90 around here, but we do get runs of days where it will be in the high 90's and high humidity. It does cool down at night though, and even without a/c the house has never seemed to get above the mid 80s at the hottest. It helps that I have a big house, lots of thermal mass that, in the event of a power outage, will slow down the rise in temperature if it is hot out.

I guess I am the opposite of you - I worry about winter more than the summer. It can get in the single digits for a long time here, and power outages are common. I have a generator that I start manually now, so when I lose power in the winter and I am home, I keep the tank running and the house warm (priorities in that order!). If I am away and the power goes out, I have to rely on neighbors to baby sit the genny, and that adds a lot of stress. There is a standby generator in my future!

When my return pump failed and the skimmer was the only pump running in my sump the sump temp climbed about 12 degrees. Its. Sicce 1000 on a diablo 200. I'm actually thinking of changing it to a dc pump hope thatll help with the heat. Granted that was in my sump of only about 15 gallons of water. With the whole system circulating it doesnt get that hot

My tank is usually always like 80-82 or higher. Sometimes 84. But thats because its up on the 3rd level in my bedroom.. my bedroom is small too.

Its a 6 foot 135g tank. I have 20g qt tank in the room. 5g qt tank and my 60 gallon hexagon fresh water tank.

The 60g is set to 80-82 because i have discus in it. I have a 36 inch LED full spectrim light on it.. and a 36 inch on my 20g qt tank.. my 135 has two 4 bulb t5 lights above it.. Meaning on fixture is 48 inches one is 24 inches so i can have the full 72 inchs of the tank lit. I DONT LIKE 60 inch fixtures they really do not cover the entire tank despite what people claim.

Plus finding 60 inch t5s is hard.. its much much easier finding 48 incj and 24 inch ati t5s locally and online. So i have in essence 8 t5 bulbs. Sitting about 9 incjes from the rim of my tank. I also have a 36w and 24 uw uv sterlizer.

The room has a ceiling fan on full blast 24.7. You can walk upstairs and feel the house change from like 74f to the 80s in a instant lol.. granted upstairs is always hotter in a house.

Anyway... I also have my gaming pc in this room so if my door is closed and im gaming for hours i actually start sweating... my room csn go to 86f quickly.

Ive nevee noticed this wffect ny corals or fish..

Ive even seen the 300w heater come on at night when the pc and lights ect are all off.. which means ny tank is dipping down to 76-77f i have the heater set to 78.

So my tank will be 84f then 77f at night sometimes. Hasnt done a thing to any corals.. I think corals are naturally in these temp ranges anyway in the wild.. bleaching only happens when temps reach the 90s for extended periods of time.. the 80s is perfectly fine

Yep, totally opposite climates. Low 80's are not uncommon night time lows here in summer and I don't recall a day that we had below 20° last winter.

I'm with you on the standby generator! We have natural gas so it wouldn't be a difficult install. Just can't seem to get the funds stored up to do it.

I have an older BioCube 29 with about 23g of water in it. I have 3 pumps total, all in the tank. 1 circ pump, 1 chaeto reactor pump, and the pump in the WS-1 skimmer. Lighting is Steve's LEDs. When all 3 pumps are running and lights are on, with a room temp of 70-72, tank temps can climb up to 83 or 84, perhaps higher, but I always drop in ice bottles around 83. If I turn off the reactor pump and/or the skimmer, the temps stick around 80/81 in the summer.

As things cool off here and room temp is more in the 60-65 range, tank temp maxes out around 79. At night when house temps go into 50s, the tank hovers mid 70s and heater comes on at 77.

Youre problem is that cube doesnt have enough water surface area to dissapate heat. Thats the only downside to tanks with weird sqare or hexagon dimensions is surface area.

If my tank hovers at 84f in a room thats in the 80s with the equipment i have and 60w of uv and youres is at 83 with room temps at 70.. wow

Agreed. For next summer my plan is to add the solid state chiller deal I read about on here recently. Seems like it would be a perfect fit for my use case.
