Q: Photos in the Assembly PDF (https://www.williamsbrewing.com/pdfs/B72.pdf) show 1900 W and 500 W power switches yet the description and site photos show the 1900 w label has been pasted over with a 1000 W sticker. Why? Is it possible to buy the 1900 W ?

A: This was a pre production prototype for the American market. Current models all have 1000 watt and 500 watt switches. A 1900 watt switch is not available in North America.

Q: What's the temperature difference between the heat on and off about the set point? The Mash and Brew is 10 degrees F.

A: The temperature differential of both the Mash & Boil and Robobrew is 5°. People are seeing larger swings in the small pocket under the grain basket because the heating element is near the thermostat (this protects the non-replaceable heating element from overheating and damage. For more on this, see page 10 of the instruction pdf attached to this product.

Q: What kind of efficiency should I expect with this? I may be missing something but I don't see a convenient way to sparge. Is there a way to prop the "grain pipe" on the top rim of the vessel and pour sparge water through?

A: Yes, the grain pipe is propped up on the rim with three feet. To do this, just lift the basket and twist when you get to the rim. This is just like the Mash & Boil and Grainfather. Efficiency will vary depending on many factors, but this is a very efficient system.
