Chillers and Room Temp

[divetoday]

My question: how much does running a chiller add to the room temp in a room that already runs a little bit warm? Does running the chiller make the room warmer, thus requiring the chiller to run more often?

My DT is on the outside wall of the house in a room that is a converted carport. The room always runs warmer than the rest of the house, but I’m able to keep the tank temp at 80-81 during the summer using evaporative cooling and keeping the doors to the sump open.

After hearing a presentation by Julian Sprung on hurricane preparedness, I’m thinking about adding a chiller. The main reason would be to run it from a generator in the event of a significant power loss. However, if it would also help me run my tank without the sump doors open at a better temp of 78-79, all the better.

Don’t know if I’m overthinking this, but would appreciate feedback.

How big is your generator? Would it run other appliances as well? The reason I ask is that after Hurricane Irma, we were without power for 9 days. My husband’s office had power and he threw a bunch of water bottles in the freezer every morning and put 2-3 in the tank twice a day. Granted my tank is a 40g but it only got to 81 degrees in an 89 degree house and saved my fish. I don’t have a chiller so I don’t know about the heat it generates or how much power it draws. It sounds like a good plan if your generator can run it long enough.

In my view, running a chiller within the room is at least partly counterproductive. A chiller generates more net heat than it removes, but not all of the heat removed from the aquarium goes back in. Much of it is removed to room convection and your AC system. So, yes, if the chiller raises the ambient temperature of your room then it will run more frequently. Although I appreciate that not all systems will allow it, if you can locate the chiller outside is much better.

The generator is big enough to run the tank and chiller, but that is about all. I’m wondering if a whole house generator might be the better answer.

I hadn’t considered that! Thanks!

I am currently playing around with cheap Temperature controlled switches, I have a waterproof temp probe connected as well as a fan which blows accross the top of my sump. It has worked prety well so far!
