Can switch Working Hours between 8:00 - 18:00 (10h), 6:00 - 20:00 (14h), or 24h.
The Steam Hub is a steam-powered contraption that is basically a smaller version of the Heat Generator Tower. When powered by the Generator, these devices create additional Heat Zones around them. They can only be built on Streets, and have a built-in clock/timer that can be set to keep the hub on during Work Hours (8:00-18:00), Extended Work Hours (6:00-20:00) or 24 Hours per day. Each active Steam Hub will consume about half as much Coal as the Generator based on its Steam Level (at the same Range Level, and before efficiency research).
Steam Hubs also serve as refueling stations for Automatons, which will walk to the nearest Steam Hub and dock with it in order to refuel twice a day, although this refueling trip does not affect their productivity.
Steam Hubs should not be confused with Steam Cores. Constructing a Steam Hub does not require a Steam Core.
The values below are for Range 1; for Range 2, double the relevant value.
- Research Steam Hub Range Upgrade II (Technology): +50% Heat zone radius, consuming twice as much Coal.
- Research Steam Hub Efficiency Upgrade (Technology): -33% consumed Coal, i.e. 1 per range setting (to 2 or 4).
- It is useful to provide heat to working areas and shelters in order to prevent frostbite and to expand to other places beyond the Generator's area.
- Heat zones created by steam hubs and the generator do not stack, so any overlap is wasteful.
