Drafting the Furnace has an effect on the Freezer, as detailed in both a laboratory note and Drafting Strategy: Architectural Digest Vol. 2. The Furnace will immediately start to heat the mansion, eventually thawing the Freezer if one is present. The effect will spread the fastest within two ranks of the Furnace Rank position, but will eventually spread to the rest of the mansion. See Freezer for more on this.
Additionally, when a player with frozen assets enters the Furnace, the heat from the room will melt the frozen effect. Once melted, resources will be usable once more, but will no longer carry out to the next day (although they can be frozen again by entering the Freezer, if it is not warm enough for the ice to melt).
Spoilers Within
This section contains spoilers for ducts.

The Furnace has power ducts running across the ceiling and connecting to its door, allowing it to receive steam power. It must be drafted from either a power source, e.g. the Boiler Room, or from another room with ducts which can receive steam power. It also has an increased chance to draw and be drawn from certain other rooms with ducts.
While the Furnace is powered by steam power, entering it will cause it to forge and produce a normal key from a tray that appears in the back.
If steam power is diverted away from the Furnace and then redirected back to it, then entering again will cause an additional key to appear in the tray. This can be done any number of times, though the Furnace must be re-entered each time. The keys will stack in the exact same position if they are not collected.
