Well it took three kettles of boiling water to defrost the rig, and about 10 minutes of running the inline filter under the hot tap, but I'm finally up and running. Some thing frustrating about spending a mortgage payment or two building a hard plumbed, stainless, single tier HERMS setup, that's all but useless in this weather; meanwhile the frugal Dennybrew blue cooler approach is up and running in the kitchen immediately.
On the plus side, by the time I'm mashed in at this rate, the hot scotchies will be flowing after noon, so I won't feel like such a lush.
