The plywood door is still working great! It's insulated on the interior with more foam.
I've found my max temp differential to be about 45 degrees. In the winter I can keep it just above freezing, summer it's happiest around 44 without ice buildup on the AC.

I love my keg washer! I also use it for cleaning my draft lines. I bought a short piece of tubing. On one end I put a threaded barb that screws in where the shaft normally seats, and a ball lock attachment on the other end. I place the pump in a bucket of warm water with BLC, stick a return tube...

I just got one that hangs on the side of my 17g boil kettle. I placed it just behind the whirlpool input port and it seemed to work fine. The circulation continued below the spider. My plate chiller was much happier and the pellet hops stayed put in the spider.
I recently did a parti-gyle triple IPA followed by a standard. No bittering hops, only whirlpool. Mosaic, Simcoe, Amarillo, and Summit. Fantastic. After the results I don't think I'll be adding bittering hops for some time.
A friend works at a tech company and gave me a unit that was going to be scrapped. Works fine and looks easy to set up.

I did put up a vapor barrier and can see condensation from the inside on the wall side of the barrier. Humidity is rarely bad in Portland. I also put out some DampRid.
It was used for packaging a discontinued product. The company is dismantling them and didn't want to fill up their dumpster with foam. Having a standard size helped tremendously in the build.
The garage isn't heated but the controller can kick on a space heater if needed. I haven't set that...
kpr121: I'm not sure of the R value, I just know it's working. The first night I tested it down to 37.4 F and it held ok. Right now I'm still working out some electrical but keeping it at 40. I did get some icing on the coils but fixed that by moving the fan closer, and installing a single-pole...
I brewed a batch that fermented in August, in my garage. Not a good idea. Temps were very high and I wound up with a beer that while still tasty, was way off from my intent. That led me to the interwebs to find a way to control temps. Eventually I found some people who had built their own...
