Cogeneration space heaters are defined as space heaters that simultaneously generate heat and electricity in a single process. In principle, they can also be designed to also provide heat to deliver hot drinking or sanitary water at given temperature levels, quantities and flow rates during given intervals and be connected to an external supply of drinking or sanitary water.
In such cases, information about their water heating energy efficiency shall also be provided in the energy label, by using one of the following two options:
- Use the labels foreseen in Regulation (EU)811/2013 for cogeneration space heaters and for combination heaters.
- Use the label foreseen in Regulation (EU)811/2013 for combination heaters including the pictogram corresponding to the electricity function.
It is to be noted that the seasonal space heating energy efficiency of combination heaters needs to be determined according to point 3 of Annex VII of Regulation (EU) 811/2013. In the case of their water heating energy efficiency, point 5 needs to be applied, which mean that their electrical efficiency is only taken into account for the determination of their seasonal space heating energy efficiency. When the review of the Regulations is carried out, this point is to be taken into account.
For solid fuel boilers, the water heating efficiency is not regulated. It is sufficient for solid fuel cogeneration combination boilers to use the pictogram corresponding to the water heating function and the electricity function as indicated in Annex III of Regulation (EU) 2015/1187.
