I got a new Worcester Bosch boiler and zones/heating controls a couple of years ago and overall find it good (helluva lot better than the 1980s gas boiler that was there previously), if I was doing it again though I'd get a Viessman boiler instead along with either Nest, Tado or Drayton Wiser smart controls. My brother has such a setup (with Tado) and the big advantage over the WB/ EPH Ember system I have is the support for Opentherm, where the smart controls can change the temperature of the boiler flow to the rads based on the temperature/weather, so if its not that cold out it can run the boiler at much lower temperatures which maximises efficiency, meaning reduced bills. Good (long) thread on boards.ie about some of the options

Decent overview of Opentherm here:
