Remove full load hours from heating technologies in the built environment

[mabijkerk]

Context

Heating technologies in the buildings and households sector have the full_load_hours attribute defined. For example for households_space_heater_coal:

- full_load_hours = 0.0

For buildings_space_heater_network_gas:

- full_load_hours = 2000.0

Current shortcoming

These attributes however seem to have no use. They are overwritten by Fever, with and without Merit turned off. See the following query example for nl2019 on the latest version of the model:

V(buildings_space_heater_network_gas,full_load_hours)
2019: 1,107.8648321675469
2050: 1,107.8648321675466

Proposed enhancement

Ideally, we don't leave code lying around that has no use, it is only confusing for contributors to see attributes that are ignored and useless:

• Check with a developer if indeed the full load hours are always changed by Fever, for start and future year, with and without Merit
• Remove the attribute from ETSource for relevant nodes
• Remove the attribute from ETDataset node source analyses

@kndehaan is this something that can be part of the clean up? If so, please schedule and reassign as you see fit.

Seems logic to me to pick this up in clean up!
