Underfloor heating - connecting to Worcester boiler issues

BourneBN20

Hi, does anyone have any experience connecting underfloor heating to a Worcester boiler?

I currently have a Worcester Bosch boiler (Greenstar 4000 30kW) with an Easy Control thermostat operating the central heating system. The EasyControl app links straight to the boiler, so would bypass any zone valve operating outside the boiler.

We are installing underfloor heating with a separate flow and return to the boiler (yet to be connected), presumably via a zone valve in an S plan system.

We’ve been advised to buy 2 x Room Thermostats from Worcester Bosch, product code 8750 00 1003.

Does anyone have experience of making this system work with the above Worcester Bosch products? 

Thanks!

I see you have asked the same Q on the Screwfix plumbing forum.  I cannot find that W-B part number (and it was that that led me to Screwfix).

UFH requires a lower water temperature than radiators.  Normally done via a manifold with thermostatic mixer valve and its own circulating pump.  Room stats controlling the UFH actuators for the loops to each room.

Normally you'd be asking the UFH system designer and or installer for advice and how to do such stuff.
