Have tried both capital and none capital. Double and single quotes with no luck…

  action:
  - service: climate.set_operation_mode
    data:
      entity_id: climate.balkon_convector
      operation_mode: "heat"
  - service: climate.set_operation_mode
    data:
      entity_id: climate.balkon_floor
      operation_mode: 'Heat'

heat should be correct and actually HA is complaining about Heat (capital h) used by your second action.
