Extent: E+W+S+N.I.

(a) From 1 January 2018, the seasonal space heating energy efficiency of air heating products shall not fall below the values in Table 1:
Table 1
First tier minimum seasonal space heating energy efficiency of air heating products, expressed in %
To be declared in the relevant tables in this Annex and in the technical documentation rounded to one decimal place.
ηs,h
Warm air heaters using fuels except B1 warm air heaters with a rated heat output below 10 kW and except C2 and C4 warm air heaters with a rated heat output below 15 kW
72
