As to the current status: It seems that the label for boilers and combi systems will be the first to be implemented. This may be a problem since for combi systems you need Lot 2?? In the latest version for boilers, there is a surprising change introduced: a supplier of both solar and a conventional boiler is now allowed to label the package. This was limited to the dealer / installer. Currently we are waiting for the commissioner to make the working documents a formal proposal. The last obstacle is a protest from EHI: Max. label class for gas boiler must be A and the efficiency should be mentioned on the label. The commission seems to move in their direction, but it does not have much consequences for our business. There is no formal new date for the implementation. We are just waiting for Outinger.
