In some of my prior threads I mentioned I was going to use an aquarium pump to pump cold air from my fridge to a fermenting box (esky) to keep it cool. Whatever you do, DON'T DO THIS. The air they pump is warm (20 degrees)!
If you want the details on wasting a lot of hours and $80, then read on...
Firstly, I spent hours trying to find an air pump that would blow 40-60 litres per minute. A thread came up here with the answer a week after all my searching. After finding out from another AHB member that the body of the pump didn't get warm, I immediately bought a 60 litre per hour pump at $80 or so. The day after my purchase, Ross visited the store and posted here how noisy these high volume pumps were. Too right!
Finally had a few hours to spend today to think of how to get this noisy air pump to work most efficiently. Ended up widening existing holes in fridge and esky which is a very unpleasant task using a hole saw as there is no guide for the larger saw. Hooked up the pump and started pumping air at minus 2 degrees via a direct connection to my fermenter box (esky).
End result - absolutely nothing!
Couldn't work this out but finally had a frightening realisation and shoved a thermometer up the outlet air tube and it read 20 degrees! So, if you want to warm air from minus two to twenty then here is your answer!
Seeing as I rarely get time to tool around I stupidly also cut the electrical plug of the pump so as I could put the it in my fridge. I mean, at this stage I had no doubt that the pump would work. My only question had been that I probably had bought too large and noisy a pump - should I swap it for a 40lt? So, now there is no way I can return it.
There's a lot of swear words going through my head right now but hopefully by my posting here, others will not go down the same track.
The pump I bought runs 8 aquariums so I may give up brewing and take up fishing or whatever you call it. Better still, maybe, I can use the ******* as a fan heater in winter?
