The glad wrap is great, also lets you see down in to the fermenter and have a look at what's going on without having to remove lids, condensation and krausen being a much more reliable indicator of fermentation health than the ploop ploop sound

Are you saying that it's a non working fridge?


Nah, it works fine, previous owners got rid of it as apparently it was freezing the veggies and got a new one. Not too old and in decent nick, not dirty and no smells etc.

What I meant to say was I use it for the insulation, not cooling. Free and no running costs = win.

no running costs

 

My last ferm fridge costed me about 60 cents a month run in summer, when it was sitting around 18 degrees... tested with a watt meter...

 

I will benchmark my new one again this one this summer over a hot week. I should have done this over winter too.

 

Costs considerably less to run at 18C than it will at say 2C.

For sure. However where mine is it hardly reaches a stable 20c ambient anyway even in summer so for my use it's for the insulation for winter when it hits ~13c at worst. It's in the old boiler room in the middle of the house so temps are quite stable anyway. A very good idea though, picked up on it from someone on here :)

I highly doubt it would cost a few hundred dollars a year to run a fridge for fermentation temp control...

Not for most, see decr gets along fine gets along fine without running one at all.  For me though it may, since 35-43C temps here Nov-April and the only place I could put one is in direct sunlight or a tin shed.  A running fridge would cost to run, a non running fridge worse than an esky/insulated box that I could have inside the house for me.  But feel free to miss the point.

I dunno about 'a few hundred dollars a year'. Even in direct sunlight, out in the exposed area of my black bitumen driveway with some reflective mirrors shining their arses off, I reckon any shitty old fridge would still only add up to a few shillings.

I think we need Choice to run a comparative test on this one Pablo :) .

Likewise, miss the point

 

The point being I don't see how you can keep it at say 18-20C on a 35-43C day unless the ambient temperature in your house is 18-20. I mean, if that's the case then fine. Must be refrigeration since evaporative won't get near that low. 

 

Run RCAC 24x7 for a whole room that's got to be more cost effective than a fridge  :ph34r: :ph34r:

Don't even need an airlock with the lid either. Been using gaffa tape over the hole in the lid on my FV for ages with no problems at all. Just don't tighten the lid on fully.

As I don't have enough height in my bar fridge to fit an airlock, I resorted to spraying some sanitiser on a freezer bag, and on the outside of the fermenter lid around the airlock hole, then putting the bag over the hole to seal the hole and used a small weight to hold it in place. If there is positive pressure in the fermenter, the gas can force its way out from under the freezer bag, but remain closed the rest of the time. I haven't had the bag suck into the fermenter (even when I forget to take it off during transfer for bulk priming), so I count that as a win.
