Hello everyone,
what are the regulations for calculating the primary energy factor when using an electric resistance heating system with a boiler?
The EnEV_2009 states in the Federal Law Gazette, 2009, Part I No. 23, issued in Bonn on April 30, 2009:
" Appendix 1
2.1.1 ...For electric power ... the primary energy factor of 2.6 is to be used for the non-renewable portion."
Why does it specify "non-renewable portion" and what about the renewable part? Does this mean that if you have a green electricity provider, the factor is effectively zero?
Thank you in advance!

Hello,
"Non-renewable" refers to the share of the direct electric heating in the total demand, which is certainly not 100%. Special tariffs such as "green electricity" do not count here and are not considered.
