I re-did our heating a while ago and split it into 3 zones: downstairs,
upstairs (less bathrooms), bathrooms+airing_cupboard+workshop. There
were a number of people saying it was a waste of effort because of the
open staircase. In practise it's been great. If I'm working at home
during the day I have the downstairs heating on and the upstairs stays
cold. The only regret is that I didn't add a fourth zone for just the
office.


My office has so many computers in it, plus a PABX and a dist amp for
TV, and canners/printers/hubs and routers..that it stays toasty warm
whatever the weather.

I agree that the more zones the better, frankly. Energy costs are rising
and it is starting to be a lot easier to justify the initial outlay.
