What is a Baker's System Manifold for Underfloor Heating?

Question

My uncle is plumbing my new house, though he is not a qualified plumber and I am abit curious to say the least about this baker's system manifold that he has came up with for the underfloor heating. Can someone please explaing this what it should look like and what functions it should have..If even such a thing.. Just so I can go back to him and ask questions when he comes back...if he comes back...;

Answer 1

Never heard of it.  Under floor systems do need a monifold for zone control but I have no idea what a "Baker's System" is.
