Oxygen not Included features different biomes in the game. These biomes represent the changes in Temperature, Metals, Gases, Plants, etc. Each biome consists of Plants, Metal, and Solids that suit the temperature and location of that biome.

Oxygen not Included Biomes

These biomes are located in Asteroids. There are nine Asteroids in total, which include:

1. Terra
2. Oceania
3. Volcanea
4. The Badlands
5. Verdante
6. Oasisse
7. Rime
8. Arboria
9. Aridio

Inside each of the Asteriod, you are going to find a combination of these biomes. Therefore, the location of these biomes depends on which Asteroid we will be looking at.

Below we will be discussing the features and stats of these different biomes provided to us. There is a total of ten biomes in Oxygen not founded. These include:

Caustic Biome

The temperature of this biome is 40°C which shows that the biome is pretty hot. The Bleach Stone keeps the Duplicants happy with a Hand Sanitizer and Phosphorite is used as a fertilizer for Pincha Pepper.

Pincha Pepper plants produce Pincha Peppernut for the Electric Grill and Balm Lilies make Vitamin Chews. Chlorine Geyser is used as a renewable source for chlorine.

• Temperature Range: 40°C
• Metal: Iron Ore
• Rocks: Igneous Rock
• Minerals: Phosphorite, Algae, Bleach Stone, Coal, Coal Steam Vent, Natural Gas Geyser, Chlorine Gas Vent, Oxylite

Temperate Biome

The place is not that warm and provides you with clean water. Copper is used as a decor booster.

Muckroot, Mealwood, and Bristle Blossom plants provide you with food. You are provided with five Oxylite tiles for oxygen while for later, you can do research on how to generate more Oxygen.

For more on Oxygen Not Included, be sure to check out our Duplicants Guide, Plants Guide, and Temperature Management Guide.

Temperature Management plays a huge role in every aspect of Oxygen Not Included. Whether it is the plants or the duplicants, all of them depends on the temperature being perfect for them. A little too cold or too hot temperature shift can cost you your plants, items, and duplicants. You need to be very focused when maintaining the temperature as it’s not just one thing that causes the change. Your duplicants, items, resources, and the biome itself – everything plays its part in effecting the temperature of the environment.

Heat output is shown by DTU per second in the game. DTU per second is equivalent to Joule per second or Watt.

Oxygen Not Included Temperature Management

If you are stuck in a colder environment and want to tone it down a little to the hotter side then it is much easier than doing the opposite. Be it the Duplicants or the plants or even the items you possess all of these things to produce and spread heat. Hence, it is easier to heat the environment.

Oxygen Diffuser
Produces 1.5 kDTU/s of heat.

The Power Transformers
Produces 1 kDTU/s of heat.

Ceiling Lamp
Produces just 500 DTU/s of heat at 10W of power. Fits right above Sculpting Block.

Space Heater
Produces 18 kDTU/s heat at the cost of 120W of power. Not worth using as its only other effect is meager 10 Decor.

Coal Generator
Produces 9 kDTU/s of heat, or 1.5 kDTU per 100 Watt produced. Utilizing it can be tricky, due to a large amount of Carbon Dioxide in the exhaust.

Charged Battery and Jumbo Battery
Produces 1.25 kDTU/s of heat when charged. They’re small, short, clean and useful in other ways and so a good way to provide extra heat.

Electrolyzer
Produces 1.25 kDTU/s of heat, but its output gases are 70 °C. Has a disadvantage of producing Hydrogen, which quickly cools down, if it is cold, due to its relatively high thermal conductivity.

Cool Steam Vent
Outputs steam at 110°C. It can be cooled down into 90 degrees Water, which then can be piped around the colony, for example to Shower. The heat will then radiate from the pipes.

A nearby Biome can provide a surprising amount of heat or cold. Biomes do not keep their temperature after map generation, so this is a temporary source.

Hot Environment
If the environment is more on the heated side then it can be more troublesome and there aren’t many ways to cool it down. Some ways to cool down the temperature include:

Steam Turbine
Converts heat above 125°C into electricity.

Ice-E Fan
Occupies a duplicant and uses up water. It cools the gas at 32 kDTU/s.

Anti Entropy Thermo-Nullifier
Provides quite a lot of cooling by consuming hydrogen.

Wheezewort
Works rather slowly in most gases and natural setups and cannot be mass-produced, but does not use any power. It’s cooling is equivalent to 12 kDTU/s in the best circumstances.

As you can see, there aren’t many ways to conquer the heat here. So what you should do is, from the starting of the game you should take measures that are going to move the hear away. This way you wouldn’t have to deal with the temperature change of this level later in the game. These measures include:

Plant irrigation is one of the worst places to misplace extra heat. Dump excess heat in cold biome. Acquire cold gases and cold water from cold biomes. Do not use hot water to irrigate cold-loving plants (Bristle Blossom).

1. Use insulated pipes in the sections that need to stay cool.
2. Pre-cool the water by winding pipes carrying it through cool areas.
3. If you have no choice, use valves to avoid storing excess hot water in farms.
4. Avoid create machines like Polymer Press or Metal Refinery, but Ranch critters instead.
5. Use Igneous Rock pipes for hot fluids/gas in early-mid game. At late game use Ceramic and insulation when managing really hot fluids/gases.

Specific Heat Capacity

This property quantifies how much an object’s temperature changes if one adds or removes an amount of heat energy, per unit mass. Its unit is Joules / (Gram * Degree Celsius). Objects with larger specific heat capacity can hold more heat or coldness.

An object’s heat capacity is the specific heat capacity times the mass of the object. Conversely, the specific heat capacity of an object is equal to its total heat capacity divided by its mass.

Thermal Conductivity

This property defines how quickly heat can be exchanged between two objects – where walls, resources, gas, liquids, plants, and items – all are objects. The rate at which two objects exchange heat is defined by the lower thermal conductivity value of both objects.

Its unit is DTUs / (Meter * Second * Degree Celsius). In this game, a Tile is considered to be one meter high and wide.
