Furnace

Incinerator that generates 50 u/s by burning items as fuel.

Overview

The Furnace is a power generation device that burns any item as fuel to produce 50 units per second while active. It features a 10x10 hopper inventory, burns items at 30-second intervals consuming durability or quantity, and can sustain a full day of operation from a single hopper of fuel. Unlike solar, it works 24/7 regardless of weather or time.

How It Works

The Furnace burns any item in its hopper inventory as fuel at 30-second intervals. Each burn cycle consumes 1 durability point from items with durability, or 1 quantity from stackable items. A full 10x10 hopper holds 2,880 squares of fuel (1 day of continuous operation). Load ratio is tracked as a SyncVar for network synchronization. When active, the furnace generates a constant 50 u/s output (output_1) until fuel runs out or is toggled off.

Fuel Mechanics

  • Any Item Accepted: Furnace burns absolutely any item — clothing, weapons, tools, loot, etc.
  • Durability Consumption: Items with durability lose 1 point per burn cycle (30 seconds)
  • Quantity Consumption: Stackable items lose 1 quantity per burn cycle
  • Burn Interval: 30,000ms per cycle (fixed rate)
  • Maximum Load: 2,880 squares enables full 24-hour operation at base burn rate

Wiring Examples

Furnace Only (Nighttime Power)

Furnace (50 u/s)
Battery
Devices

Use furnace as primary nighttime power source. Battery stores excess for consumption spikes.

Furnace + Solar Hybrid (24-Hour Operation)

90 u/s (combined)

Solar powers day, furnace covers night and cloudy periods. Battery buffers transitions.

Tips

  • 50 u/s equals T2 Solar Panel output — ideal for bases with 50+ u/s demand
  • Works 24/7 unlike solar — perfect for nighttime power, backup, or primary generation
  • Burns ANY item — use for junk disposal while making power (clothes, broken tools, etc.)
  • 30-second burn interval at steady rate — highly predictable power generation
  • 2,880 squares hopper = 1 full day of fuel — significant storage per refill
  • Combine multiple furnaces for 100+ u/s on massive group bases
  • Load ratio SyncVar ensures all players see consistent fuel status
  • No external fuel sources needed — turn loot directly into power
  • Pair with battery to buffer variable consumption and extend backup runtime
