The seasonal space heating energy efficiency class for the medium-temperature application (55°C) should always be displayed on the space heater package label, except for low temperature heat pumps, i.e. when the package label is accompanied with the label of section 1.1.4 or 1.2.4 of Annex III.
In those cases, but only then, the seasonal space heating energy efficiency class for the low-temperature application shall be displayed. If both seasonal space heating energy efficiency classes are shown on the product label (section 1.2.3 or 2.2.3) the one for the medium-temperature application should be displayed on the package label.
