I would still appreciate an answer to the question of whether it makes sense, for example in the bedroom, to open the valve slightly. Currently, it is still closed and at about 20 degrees in there, I find it rather too warm. With even more intensive ventilation, we might be able to maintain 19 or at least 19.5 degrees, but I wouldn’t know why I should create a small flow here?
And a completely different question. The heat meters built into such devices, are they standardized, calibrated, tested? If I assume that these values are correct, then during summer (i.e. for hot water) I reach a COP of about 4, and now during the heating + hot water phase over 6. Overall, since the start in May, I am at a COP of 5.4 with a tendency to rise quickly. Is this due to manufacturers’ optimistically measured heat quantities or is this realistic?
