Because hot air rises.
Room heaters are typically placed at a lower level to ensure heat is distributed evenly throughout the room. Placing the heater at a lower level allows warm air to rise naturally, helping to maintain a comfortable temperature throughout the space. Additionally, having the heater at a lower level reduces heat loss through the ceiling and improves efficiency.
air-conditions are usually placed at a higher level rather than at a lower level.
Hot air rises but not cold air.
hot air rises so the air con will cool down the air above so air cons will be placed at a higher level

Electric water heaters are more energy efficient, have lower upfront costs, and are easier to install compared to other types of water heaters.
Sometimes. Oil-filled space heaters, which are fire-safe are preferable. Regular electrical space heaters can be used if they are placed in safe places, and turned off before leaving work.
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.
Unlike warm air, cold air does not rise - it falls to the ground. Thus, it's more ideal for an AC system to be placed high rather than low.
Baseboard electric heaters are placed on the outer walls of a room in order to radiate heat towards the center of the room. They also heat up the outer walls of which usually are cooler than the inner walls.
Oil heaters are generally less efficient than other types of heating systems, such as natural gas or electric heaters. This is because oil heaters have lower energy efficiency ratings and can be more expensive to operate.
Ceramic heaters are generally considered to be energy efficient compared to other types of heaters because they heat up quickly and retain heat well. This can help reduce energy consumption and lower heating costs.
