I am considering overhauling and zoning my central heating later this
year,
and would like separate control of each rad. I'm looking for motorised
valves which are as small as possible and which will fit on 15mm pipes.
The
only ones I can find are 22mm. [Yes, I know I can use reducers - but the
whole thing is still too big].

I assume they will be visible.


Does anyone know whether smaller ones are available and, if so, where
from?

TIA.
