Different types of heaters are available in the market, and each heater has advantages and disadvantages. Like oil filled radiators heat slowly, keep the entire room warm for a long time and are not noisy, but do not provide instant heat. Quartz heaters heat quickly and are good for small rooms or bathrooms. Halogen heaters also heat up quickly, provide better heat in large rooms without oscillation and consume less power.

Ceramic heaters heat quickly, are safe and retain heat for a long time. Fan heaters are the cheapest and heat the fastest, but are noisy, can dry out the air, and can have health effects when used over a long period of time.

A similar question has created a ruckus on Reddit. Let me tell you that this is a platform, where people ask different types of questions and also share their experiences along with experts. But this time the question asked people forced people to think that by really fitting AC upside down, it will start working like a heater.

Actually, this question was asked keeping in mind the window AC. Usually a special frame is used to apply window AC on the window, the design that is such that it is not possible to fit the back of the AC in the room. That is, it is almost impossible to reverse AC. But suppose if someone fits it upside down somehow, will it be hot air as a heater?

The answer from the point of view of technology is clear that the heater cannot be made by applying normal AC upside down. By doing this, the entire system of cooling and heating of AC will be disturbed. The ordinary AC is designed to cool the hot air of the room just to cool and remove it outwards.

If it is turned upside down, neither it will be able to draw the outside air nor will heat the room. Rather, due to excessive pressure, its compressor can deteriorate and the entire AC can also be useless.

Special types of Hot & Cold AC are available to heat the room. Different technology is used in them so that it can give cold in summer and hot air in winter. These ACs do not need to be reversed, because they are made according to both seasons.

The answer to this question that arises on Reddit is that it is neither practically possible nor technically. If you want to take a heater task from AC, then special Hot & Cold AC made in the market is the right choice for it.
