Well the boiler got installed and eventually the electrician returned to
wire up the system.
Without much thought or any advice, I had opted for W plan. The circuit
diagram looked simple enough:-(
Well it is only 6 connections and earth. Even a plumber should be able
to join that up.

Indeed.
Sadly underfloor systems tend to have individual roomstats and further
complicated by splitting the manifolds upstairs/downstairs.
Boiler overrun provision also needs checking. I don't know if this is
internal to the Viessmann boiler in which case the boiler pump could
circulate through the output/return loop (about 20m of 28mm insulated
piping)
I'll have a play this morning and report back:-)
