I want to mount the new heat exchanger close to the fish tank so I can keep the closed loop short.
I have a one gallon expansion tank with an 8 Amp 12 dc pump.

Here are a couple options I have.
I can mount the fan at the top of the roof and have it blow the hot air down to the heat exchanger.
I can use a flexible duct or I can build a duct with OSB.
I could mount the fan at the heat exchanger and have it suck the air down through duct work.
Does anyway know if a car battery will work to run a 8amp 12 Volt dc motor with a small battery charger to top it back off at night.
So questions.
Is just the volume of the closed loop and a very small expansion tank enough for the closed loop?
Have the fan push or pull the air.
Flexible or ridged duct.

My pump is the UF1215

I have this to help purge the air
