CSV export / import does not work properly for hybrid heat pumps

[DorinevanderVlies]

This ETM scenario contains 100% heat pumps for both hot water and space heating.

When I export this scenario to a LES the heat pump technology is working. After exporting it to a CSV and importing that CSV again the heat pumps are not working properly any more. It seems that information gets lost in the process.

As the csv import does not have priority this issue might not be urgent.

@grdw I previously said:

However, in the following weeks we'll be constructing some variations of scenario's with hybrid heatpumps. The csv is the most efficient way to do this. Currently I still have to manually add the hybrid heatpumps. Especially in combination with the csv import this is prone to error.

I would be awesome if there is a fix for this problem.

Steps to reproduce:

Step 1: Create a les with one buffer; one hybrid heat pump

Step 2: Export LES

Step 3: Import LES

Load is gone 🤔

I found the reason. The Hybrid heat pump is modelled as a single technology consisting of two components. When exporting, it doesn't export the components but just the technology which is than just a shell with nothing in it.

• [x] Export components in a sane way
