Smith's plinth heater onto Evohome - BDR91 or HR92 control?

Hello,

Brrrrrrr! the kitchen is a little cool - i dont mind, but have succumbed to the household complaints and bought a plinth heater. :/

Should be a relatively simple install as a previous house owner had put the piping in. :)

I was thinking of using a BDR91 to switch it on and off as a zone with the Evohome controller as the temp sensor.

Another solution might to add a HR92 instead, again with the evohome controller as a temp sensor.

which would work best?


thanks,
Richard.
