Recent fever changes do not seem to work for all heating technologies in buildings

[mabijkerk]

When I open a blank nl2019 scenario on master and go to the heating technologies in the buildings sector, some unexpected behaviour arises. For a number of technologies the supplied heat goes to 0 and only deficits occur. For example, when the Air heat pump (gas) buildings_space_heater_heatpump_air_water_electricity is set to 100%:

• Air heat pump (gas): buildings_space_heater_heatpump_air_water_electricity
• Ground heat pump with TS: buildings_space_heater_collective_heatpump_water_water_ts_electricity
• Aquathermal heat pump with TS (surface water): buildings_space_heater_heatpump_surface_water_water_ts_electricity
• Electric boiler: buildings_space_heater_electricity
• Biomass-fired heater: buildings_space_heater_wood_pellets

I thought it might be related to the attribute households_supplied_per_unit = 1.0, but adding it to the air heat pump (gas) does not seem to solve the issue. The extent to which deficits occur also change per technology. The strange thing is that for the biomass heater, some deficits occur with its heat_output_capacity being 0.137 MW, whereas the condensing combi boiler (gas) does not have any deficits with a heat_output_capacity of 0.043 MW.

It is! But that attribute only works for nodes that are part of the demand_driven group. Adding this group to the affected nodes solves the issue!
