To get to temp quicker and help with a more vigorous boil on my 35L Digiboil.

I hope this will help maintain mash temperature and decrease time to boil and perhaps increase the vigor of the boil as well.

Well, 110V is on the low-end power-wise to maintain a steady boil for ~9 gl. Every little bit helps!

Check out the price! Less than 50% of the Grainfather jacket. Both should be included with the American version of the units.

Works Great
I bought this for my Digiboil (9.25 gallon 1500watt, 110volt) unit. It fits pretty well not perfectly but well enough to do its job. It lowered my warm times quite a bit.

A nice robobrew addition
Seems to speed up heating and helps maintain the temperature a bit better. For the price, it's kind of a no-brainer.

Exceeded expectations
Wrapped the robobrew in this jacket and had a MUCH faster heat experience. Definitely worth it of you want to get your brew in the fermenter faster. One thing I'd say worth noting is that my step mashes over shot temperature so set the robo brew about 5* lower than adjust up as needed. But once it's at set point it maintains very well.
