Just mashed in on my new top tier system and boilermaker pots (christmas present from SWMBO). Love everything about it, and so far so good. Got my pump hard wired in, and that alone makes a world of difference. The mash tun loses a little more heat the cooler, expected, so I fired up the burner and brought it back up to temp. Man those burners are powerful! Making my haus pale ale to break it in, a nice simple recipe. I'll hopefully post some pics later on!
