Steam is pretty good, maybe too good. But I might go back in and insulate some upper tubing. Only the top has to come off for that job.

I guess it's doing its job. Cup warmer area is still a little warm, but no where near as warm as before. I typically flush into my drinking cup so that gets it warm enough.

Pressurestat is cycling much less frequently. Worth the effort. It was a bit of a PITA.
