Furnace Whiteout Survival

Furnace

The Furnace plays an important role in Whiteout Survival as the heart of the city. It has multiple important purposes in the game.

One of its main functions is to keep the entire city warm, which allows the workers to perform at their best. Upgrading the Furnace is beneficial, as it unlocks access to new features and upgrade levels for other buildings in the city.

The Furnace has a total of 30 levels, and each level upgrade needs a specific amount of resources, including coal, wood, meat, and iron. Notably, you won’t need to have meat until reaching level 10 for upgrading the Furnace.

Similarly, coal is unnecessary for the first two upgrades (until level 3), but from level 4 onwards, a certain amount of coal is required. Additionally, iron becomes necessary for Furnace upgrades starting at level 6. This means you’ll need both iron and coal from level 6 onwards to continue upgrading the Furnace.

You can easily control the Furnace in the game using the in-game Action Panel, allowing you to turn it On or Off as needed. When the city gets too cold, you also have the option to operate the Furnace at Max Power.

However, keep in mind that running the Furnace at Max Power will require a higher amount of coal compared to its regular operation. As you upgrade the Furnace to higher levels, the amount of coal required per minute by the Furnace will increase.

Fire Crystal Upgrades

When you successfully upgrade the Furnace all the way to level 30, you’ll gain access to new upgrades called the Fire Crystal Upgrades. To perform these upgrades, you’ll need the special Fire Crystals, in addition to the regular resources you used before.

The Fire Crystal Upgrades offer brand-new skins for various buildings in the game, introducing a delightful change to the appearance of these buildings after every five levels.

  1. I have 52.2% construction speed and am trying to upgrade my furnace from 22 to 23.
    Based on the table, the duration should be reduced from (originally) 9 days, 8 hours, and 40 minutes to around 4 days.
    But what I see in the game is 6 days, 3 hours, 36 minutes, 46 seconds, which is only a 34.4% reduction.

    Although the information about the required materials is correct, the Upgrade Time on the table is not.

    Based on my calculations the Upgrade times have been increased by 37.5% since the last update.

    Reply
    • 50% speed does not equal 50% time reduction keep that in mind, 100% speed is reducing the time in half and 50% speed is reducing the time by 1/4th or (25%)
