Redmat

Redmat is a heat-producing building used in late-game heat networks. It functions as a dedicated heater whose heat output is emitted from a specific side (indicated in-game) and must be placed so that the heat-emitting face contacts the consumer or heat-transmitting blocks. Redmat is part of the family of heater blocks and integrates into the broader heat economy alongside Electric Heaters, Phase Synthesizers, and other heat sources.

Heat transfer from Redmat follows the standard mechanics: only the portion of its surface touching a recipient block receives heat, and partial contact divides the Redmat’s output proportionally. Heat receivers increase their input/output speeds according to the fraction of required heat they actually receive; excess heat beyond a consumer’s input cap has no additional effect. Mixing Redmat with other heat producers is a valid design choice when compactness or precise heat sums are required, since combinations can match consumer input needs without waste because output rates are effectively rounded by the game.

Practical notes and strategies:

• Positioning matters: align the Redmat’s heat-emitting face directly against heat consumers or heat ducts to maximize transfer. Misalignment reduces efficiency and may require additional heaters.
• Use heat-conducting blocks (heat ducts/redirectors) to route Redmat output where direct contact isn’t possible; the effective transferred amount depends on contact proportions across faces.
• Combine different heater types when aiming for a target heat input to a consumer. Certain mixes (for example, pairing large and small heaters) can achieve the same or better efficiency and a smaller footprint than using only one heater type.
• Be mindful of consumer input caps: different heat consumers have different maximum heat inputs. Supplying more heat than the cap is wasteful, so size Redmat deployments to match the specific consumer’s maximum.
• Consider spatial efficiency versus power/maintenance trade-offs: some heater setups are more compact but may be less power-efficient or harder to align with redirectors; plan layouts around available space and the intended consumer.
• Late-game planning: Redmat is most useful when building high-throughput systems where other heat sources (like Phase Synthesizers) or heat-consuming structures require substantial, reliably routed heat.
