The Anova Sous Vide Precision Cooker is a touch screen heat stick with an integrated recirculation pump. Set your desired temperature on the touch screen. The Anova heats as necessary and has a circulation pump to ensure that temperatures are uniform. Adjustable clamp and Stainless Steel Skirt.
Possible brewing uses could include: getting and keeping strike water at temp, direct use (with a filter bag in a mash tun or BIAB mash), maintaining temperature for sour mashes and getting to a boil more quickly (or helping to maintain a boil) for both all grain and extract batches.
I have a different model from Anova, the Anova One. Check out my First Looks Post on the Anova One. Anova also has an article on their website about brewing with the Anova One – note that both of these articles refer to a different unit.
