Time to Re-Wire the Brewery

I brewed last night and things didn't go according to plan!

The temperature controller that I use to maintain the temperature of the wort as it is recirculated through the heat exchanger just wasn't showing a stable temperature.  It fluctuated by as much as 20°C so any kind of control was out of the question.  I have had this problem before and I know it's down to moisture in the wiring which I've been putting off replacing for months.  I think I now have to bite the bullet.

I managed to get through by monitoring the temperature of the mash tun and the heat exchanger with a thermometer and controlling the heat exchanger manually.  A few pints of AK helped me along too!
