Because they were not safe, so the balance of the risk against the need was big
The use of heaters can lower humidity levels in a room because heaters can dry out the air by increasing its temperature, causing moisture to evaporate more quickly.
Most heaters heat a room primarily through convection. The heater warms the air, which then circulates around the room. However, some heaters also emit infrared radiation that directly heats objects and people in the room.
Generally, the dish heaters heat what is in front of them (often a person or persons). However, if you have a small room and close the door, it can heat the whole room. For instance, I turn the heater on at night and close the door in my bedroom. The entire room gets warm and cozy, but, once I step out of my room, the rest of the apartment is cold. The rest of my apartment is a large room that is not enclosed so the heater would never heat so large of a space. If I step out of the beam in my large room (say I was sitting on the couch in front of the TV), the rest of the room is a lot cooler.
Infrared heaters tend to be more energy-efficient because they heat objects and people directly, whereas micathermic heaters heat the air in the room. However, micathermic heaters generally provide more consistent and even heat distribution throughout the room. The choice between the two will depend on your specific heating needs and preferences.
A space heater heats a room by transferring heat through convection, radiation, or a combination of both. Convection heaters warm the air, which rises and circulates around the room. Radiant heaters emit infrared radiation that directly heats objects and people in its path.

Heaters come in various sizes, depending on the size of room you need to heat. For large rooms, you may need to invest a bit more money. Home improvement stores have them and some department stores

Candles that have just come out of the microwave will burn faster because the microwave has already burned it as it is, adding a flame will just continue the process. Whereas if it was room temperature you would have to start the whole process from the beginning.
Ceramic heaters are generally considered to be efficient and effective for heating a room. They are known for their quick heating capabilities and energy efficiency compared to other types of heaters.

Most heaters heat a room primarily through convection. The heater warms the air, which then circulates around the room. However, some heaters also emit infrared radiation that directly heats objects and people in the room.
Yes, space heaters can dry out the air in a room because they generate heat by burning fuel or using electricity, which can reduce the humidity levels in the air.
Room temperature.
You are likely to have very little room, so keep what you bring to a minimum. However, bring some office supplies, things to be comfortable (heating pad, lotion, kleenex, towels, mug), and so on. In my day, we also brought immersible heaters, but you may have access to a microwave.
Tube heaters can be used in many different environments and places that need to be heated. Tube heaters can be places in walls or flooring in order to keep a room warm.
