5.  Specific conditions for seasonal space heating energy efficiency  
 
(a) The seasonal space heating energy efficiency of all local space h eaters except 
commercial local space heaters is defined as:  
ηS = ηS,on– 10 % + F(1) + F(2) + F(3) – F(4) – F(5) 
 
The seasonal space heating energy efficiency of commercial local space heaters is defined as:  
ηS  = ηS,on  – F(1) – F(4) – F(5) 
 
Where:  
— n S,on is the seasonal space heating energy efficiency in active mode, expressed in %, 
calculated as set out in point 5(b);  
— F(1) is a correction factor accounting for a positive contribution to the seasonal space 
heating energy efficiency of electric stora ge local space heaters due to adjusted contributions 
for options for heat storage and output; and a negative contribution to seasonal space heating 
efficiency for commercial local space heaters due to adjusted contributions for options for the 
heat output,  expressed in %;  
— F(2) is a correction factor accounting for a positive contribution to the seasonal space 
heating energy efficiency due to adjusted contributions of controls of indoor heating comfort, 
the values of which are mutually exclusive, cannot be  added to each other, expressed in %;   — F(3) is a correction factor accounting for a positive contribution to the seasonal space 
heating energy efficiency due to adjusted contributions of controls for indoor heating comfort 
the values of which can be added  to each other, expressed in %;  
— F(4) is a correction factor accounting for a negative contribution to the seasonal space 
heating energy efficiency by auxiliary electricity consumption, expressed in %;  
— F(5) is a correction factor accounting for a negati ve contribution to the seasonal space

(b) The seasonal space heating energy efficiency in active mode is calculated as:  
For all local space heaters except electric local space heaters and commercial local space 
heaters:  
ηS,on  = ηth,nom 
 
Where:  
-ηth,nom: is the useful efficiency at nominal heat output, based on NCV.  
 
For electric local space heaters:

Where:  
— CC is the electric to primary energy ‘conversion coefficient’.  
            —nth,on for electric local space heaters is 100 %.  
 
For commercial local space heaters:

Where:  
- ηS,th: is the weighted thermal efficiency, expressed in %;  
 
-ηS,RF  : is the emission efficiency, expressed in %.  
   
For luminous local space heaters, n s,th is 85,6 %;  
 
 
For tube local space heaters:

Where:  
- ηth, nom : is the useful efficiency at nominal heat output, expressed in %, based on GCV;  
 
-ηth,min: is the useful efficiency at minimum heat output, expressed in %, based on GCV.  
 
-Fenv : are the envelope losses of the heat generator, expressed in %;   
 
If the heat generator of the tube local space heater i s specified by the manufacturer or by the 
supplier to be installed in the indoor space to be heated, the envelope losses are 0 (zero).  
  If the heat generator of the tube local space heater is specified by the manufacturer or by the 
supplier to be installed  outside the heated area, the envelope loss factor depends on the thermal 
transmittance of the envelope of the heat generator according to Table 4.

and the settings that determine the performance of a the tube segmen t are identical to those of 
a single tube local space heater.
