This seems to be a copy-paste error with {Fuel}

sorry, I am failing to see the copy-paste error - could you clarify? @danielhuppmann

There is a tag {Fuel} in the description but no corresponding tag in the variable name - and the whole second part of the description doesn’t make sense to me…

I meant to explain why there is an explicit Electricity|Heat Pumps version of the Secondary Energy|Heat| variable, but no explicit Electricity version - that one is already included in the {Fuel} version of Secondary Energy|Heat|.

But I can easily remove this explanation if you find it self-explanatory

I still don’t understand what you want to say. But in any case, please remove the curly brackets because are reserved for tags that are automatically replaced - and they can only be replaced if the same tag is present in the variable name itself.

good to know. I just updated it accordingly
