Some thoughts regarding home heating
Thermostatic (z-wave) valves, such as Danfoss LC13 or Popp they do calculate the inertia of the room and they do close if a window is open near them.
This means with the calculated inertia they could close the valve before schedule because, with the existing heat on your radiators they know they will achieve the set point in certain time. So they can close the valve and save that energy.
Also, if they detect a sudden drop of temperature, this is normally linked to a open window condition. So the close the valve to avoid wasting energy.
The issue I have found is they do not send that information to the controlle! Normally the unique information available on the valves is heating point and in some cases the temperature of the room. But not the %open or the “window feature”.
So it could happen all your radiators are closed, but your controller is asking the boiler to heat, because it hasn’t got this information. This means, the “energy saving” part you will not have completly (and if you have thermostatic valves in all your radiators and all of them are closed, while the boiler is on, you could cause a damage to it)
It would be nice to have access to this information from the valves: %open, open-window situation, and that information to be considered into the thermostats (also virtual thermostat from Zipato).
If any of you has dealed with this concepts/situations and would like to share some comments, it would be nice.
