I've just finished building the setup.
I had the grainfather already and was looking to expand. So when brewing larger batches the grainfather turns into a herms system for the insulated ss brewtech mash tun, a HLT for sparging, second pump and temp control. I've tested the herms setup and it works well. But I'm yet to do a brew on the overall setup. The good thing retaining the grainfather is I have a large range from 10 litre to 76 litre brews. I'm pretty happy with how it turned out.
