In "Ice and Steam Age 2", the role of the heating hub is crucial and has distinctive characteristics. It provides warmth throughout the city, ensuring residents survive the freezing cold. It has a wide range of action and can cover a large area. It is characterized by high energy consumption and requires reasonable planning of energy supply to ensure its stable operation and protect the warmth of the city.
Materials and heat energy can be converted into each other. The heating hub consumes materials, and the maintenance hub consumes heat energy. 100 labor and 25 materials in the heating hub are exchanged for 40 heat energy in each area, and 100 labor and 50 heat energy in the maintenance hub are exchanged for 40 soft materials in each area.
If there is a production bonus, it is better to use synthetic materials than to maintain the hub (it will consume a lot of calories in the later stage). The heat energy (oil) saved by the heating hub can be used to make more synthetic materials.
