I'm in the middle of a brew and my boiler (a basic Karlstein)is playing up. The thermostat won't respond. So I'm starting to think of the next step. At the moment I have a boiler and a cooler box mash tun. But thinking about an all-in-one. The question I've had for ages though is how do you sparge? Guessing you don't need an additional boiler for the sparge water because that wouldn't be AIO then?
Sorry if this is a silly question and I'm sure it's been explained to me before and just nodded knowingly....
