Hi all,
We’re in the process of knocking two rooms together, and whilst we dig out the floor to sort out some damp issues, we’re going to take the plunge and add some UFH, to our evohome system.
The room is pretty large, so we need two loops, but there are no dividers, so I think I just need to control it as one zone.
The current system has a zone valve on the DHW, but no valves on the heating as it’s controlled by the HR92s on the rads. The boiler is controlled by an opentherm controller.
So correct me if I’m wrong (and I may well be!), but as I’m not zoning the different loops, I don’t need to run a manifold with actuators? This means can control the pump with a BD91, and wire in a control valve to be actuated with the pump? I have spare BD91s from some thermostats I bought, so I’m hoping this is right!
Finally with regards to controlling the temp of the UFH, it seems that the JG pump has a knob on the front with blue and red arrows. I’m assuming this controls the temp. Anyone have any experience of this?
Only other question, is do you think I would actually be better off zoning the system? The room is 10.5m long, with a lounge at one end, dinning area in the middle and kitchen at the other. Although I could get the thermostat in the middle, I wonder if I would be better with the two loops independently controlled.
Cheers,
Ian
