Heating Options Advice Please

OK, so Ive just set up my z-wave system with Vera and am enjoying immensely.

My plans are to include my central heating into the z-wave network. Currently I have a gravity fed central heating and hot water system. Each radiator has a thermostatic radiator valve and the boiler is controlled by a Drayton LP522 programmable controller. I dont have any standalone room stats.

What are my options for converting this to a z-wave controllable system? Im open to any and all ideas at the moment to help me make a decision.

I’d like to control the temperate in every room independently (manually and by z-wave)
i’d like to be able to manually switch on and off the central eating and hot water (as well as by z-wave)

Many thanks in advance
