Hi all,
We've had evohome for quite a while now and are very happy with it. It's connected to an S-plan vented system with separate zone valves for DHW and CH. We're about to redo our kitchen and this will entail moving from having a radiator with HR92 to (single zone) wet underfloor heating. As the people doing the work are not familiar with Evohome (and I'm not familiar with wet underfloor heating) I'm quite keen to get a clear view as to how it works.
My current understanding is that we will connect the HCC80R to the manifold that will be installed. The HCC80R will also power (and control) the pump which will circulate the water around the underfloor loop. We would then need a sensor in the room such as the DTS92 to measure room temperature and report to Evohome. Where I get less clear is around zone valves. The builder is expecting to add a new zone valve to the system for the supply to the heating loop. I can see various references to using a BDR91 to provide a heat demand signal to the boiler so what I wanted to check was that the bits that need to be bought are 1xHCC80R, 1xDTS92 and 1x BDR91 and that all of these will be bound into a single zone when set up on the evohome as the new kitchen zone.
The other question is whether the T87RF2025 Single Zone Thermostat can be used as a better-looking alternative to the DTS92
Any comments on whether I'm right or wrong in the above would be welcome! (or also pointers to documents I might have missed explaining this)
Thanks
Andrew
