I designed and installed central heating about 6 years ago.
I split into downstairs and upstairs zones with separate control.

My flat is long and narrow, bed one end, kit/liv the other and
split 2 zones, 2 x CM67. Two rads in the hall one on each zone,
bathroom radiator is the bypass. Works brilliantly and is
economical too.

Sadly though I can't help think that many so-called pros would have
walked or quoted a mega price if asked to do something like this.
