Warning thought & opinion rather!! I know not of what I speak

Most common way is to have grouped rooms & zone stuff with inline 
controls on the feeds (I know that wasn't the actual question)

Various people do motorised valves for radiators, they've been 
discussed before and the main issue with em was size & appearance.

> Is there any way to reduce that cabling, so we don't need to rewire
house?
Most are low voltage DC, so if they are controlled over cat5 it 
should be possible to carry the power on a spare pair (see current 
discussion on this, plus some of the links from the wireless thread).


> Also, putting power socket into bathroom is against regulations, I
think.
You can have hardwired power points (no socket wire goes into wall) 
but don't think this rule applies to low VDC so should be ok, you 
might want a hardwired point in hte bathroom anyway to avoid 
condensation in your socket.
