This area has no heat network currently, so I wanted to remove all demand and supply of heat on the central heat network. As expected, I had no problems getting rid of heat demand from the heating grid for either `present` or `future` As soon as I remove the final converter supplying heat to the heat network, however, the scenario no longer loads. \r\n\r\nAs you can see, even an infinitesimal amount of heat supply suffices (FYI: total space heating demand is 15.6 TJ):\r\n![image](https://cloud.githubusercontent.com/assets/308563/19651321/b438e080-9a0c-11e6-939d-23e139a0c660.png)\r\n\r\nsetting this to:\r\nnumber_of_energy_heater_for_heat_network_waste_mix: 0.0\r\n\r\nand/or:\r\nnumber_of_energy_heater_for_heat_network_waste_mix_present: 0.0\r\n\r\ncauses it to freeze or not load (depending on how you set it to zero, in the scenario file or by using the slider).\r\n\r\n**Background**\r\n[This scenario](https://beta-pro.energytransitionmodel.com/scenarios/592667) was created by scaling to 495 households from a NL 2035 blank scenario (no industry or agriculture, yes energy sector), except for the _future_ supply of heat and power, which was created by scaling a SER 2023 Energieakkoord scenario to 495 residences in the same way. \r\n\r\nNotifying @DorinevanderVlies "}}
