Ecohome questions

Hi

Really interested in getting evohome system for a house I've recently moved into, have a couple of questions I hope you guys can help with.

1. Currently have a Honeywell timer (ST6400C) and rotary dial thermostat installed in a nice central location, would I be able remove these and use their existing wiring to the boiler to locate the BRD91 nice and centrally?

2. I have a room with both UFH and Rads can the evohome cope with these in the same zone?

Thanks
