For my heatstick, I put a 6 foot cord on the stick, and made a 10 foot extension cord, with switched GFCI outlet. Later, I doubled the length of the extension cord.
For my upcoming 240V setup, I will have to make a 50 foot extension cord. I am going to put the 240V outlet in the garage, right under the breaker box for ease of installation. That will be a long cord when brewing in the garage, but I will need the length when brewing on the patio.
