I've DIY'd an internal cooling/heating coil for my Blichmann 14.5 G Fermenter and I've had success in the warmer months using chilled water and a pump. Basically the pump turns on when the fermentation temperature gets above a set point and turns off when it gets below a set point.
Question: is there an ideal temperature (or a formula for determining a temperature) at which the warm, circulating water should be set? The temperature in my uninsulated garage rarely dips below 32F and sits in the mid-40's most of the time. Since I brew lagers most of the time, the temperature of the wort inside the fermenter needs to be warmed 5F-20F
(but generally 5F-10F) above the ambient temperature in the garage.
