I live in New Zealand and around this time of year the temperature averages around 10-15 degrees.
I was thinking about making a wooden box to store my brew out of some basic materials from the local hardware store.
Let's say I make a plywood box large enough to keep a 25l plastic brewing barrel and my bottled beer during secondary fermentation.
If I use polystyrene walls for the interior of this box, in theory, this should keep the heat at a constant.
I will varnish the plywood to stop any water damage (The box will be outdoors) and, once assembled, fill the gaps of the box with a silicone sealant.
If my brew is at the right temp. when I place it in the box would I be right in assuming that it should be good for the primary fermentation process? Or will I need some sort of heating (Not too keen on this, really I just want something that wont use any electricity) but if needed should I use something along the lines of a light bulb attached to a thermostat controller?
Does this sound like it will work to anyone with experience? If not where have I gone wrong?
