Love your selective use of thermal mass.
A wc system like Vokera, Intergas, Coopra, vary their flow temps as they go, not the way I understand Viessmann boilers do by averaging a day?
So the thermal mass thing means the system will have plenty of time to react.
Alec..... I have been using this system in my own house. It works. Why can't you just accept that fact?
Yes the kit is expensive. But it is not just about energy efficiency.
And if you believe British Gas, then there really is no hope .
You have also harped on in the past about thermally isolating rooms? Just shut doors. It It is not hard. Any heat cap will then have the benefit of assisting the thermal mass of the building by not bringing on a zone because the wind has got up a tad.
Oh, and when I do fit these systems I tend to advise bathrooms and halls are left unzipped in order to give the boiler a better system flow and also the (usually) core of the house also has a reasonably stay heat state to help with the overall all thermal inertia of the building.
