Hi,
Your question is a good one and I'll attempt an answer that is worthy.
In wall units are exactly what they say and can be either forced draft ( use a fan motor ) or just use natural draft for air movement.
In wall units are not favored in my book, ( But ) They definetely do have their place in the world. I have many reasons for saying this so I'll just touch on a few.
Safety !!!!!!!!!,,,,,,,, flue pipes that vent off your heaters fumes often rot out because one of the flue gas byproducts is water and that eats away at the often sheet metal vent pipes from inside out and you can't see them inside your walls very easily.
Efficiency !!!!!!!!!!!,,,,,, typically not nearly as efficient as a central type heating system.
Note: I have personally witnessed several cases where people using in wall gas units had fires in their in walls and the wood was badly burned without them even being awares. The only thing that seemed to keep them from turning into a roaring out of control fire was that not enough oxygen was able to feed the flame for it to get totally out of hand. ( YET )
Hope this helps:

A forced hot water heating system is more energy efficient, provides consistent warmth, and is quieter compared to other heating systems like forced air or electric baseboard heaters.
Forced air wall heaters offer efficient and quick heating, even distribution of warmth throughout the room, and the ability to control temperature easily. They are also cost-effective and can be installed in various spaces within a home.
Examples of home heating methods include forced air furnaces, radiators, baseboard heaters, electric space heaters, and heat pumps. These systems use different processes like burning fuel, circulating hot water, or transferring heat from outside to keep your home warm.
Lasko heaters come in various forms, from Ceramic Heaters to Fan Forced and even Infrared-Quarts heaters. The sizes vary from low profile ones to high towers capable of heating large spaces.
Forced air wall heaters provide quick and efficient heating, distributing warmth evenly throughout a room. They are cost-effective and easy to install, making them a convenient option for heating smaller spaces in a home.
Floorboard heaters offer several benefits in a home, including efficient heating, even distribution of warmth, space-saving design, and reduced allergens compared to traditional forced-air systems.
Radiant heaters supply heat directly to the ceiling, floor or walls of a home. They use radiant heat transfer, which is heat moving directly from the hot surface to the objects or people in the room. This is the same effect as when you can feel the heat of stove burner from across the room. This type of heating is more energy efficient than forced-air heat because no heat is lost in the duct work. Since there is no moving air, it is better for people with allergies.
One does not. Those heaters produce carbon monoxide, which will kill you.
what is the different between natural and forced vibration systems.
Forced air space heaters are efficient and quick at heating a room, providing instant warmth. They are also cost-effective and can be easily controlled for precise temperature adjustments. Additionally, they distribute heat evenly throughout the room, ensuring consistent comfort.
You can purchase a propane forced air heater online from retailers such as Amazon. Once on the website, type "Forced air propane heater" into the search field at the top of the page and press enter to bring up the heaters.
Forced air heaters can be bought from Home Depot, Home Hardware, Alpine Home Air, Lowes, Rona, Amazon, Mr Heater, Horizon Services and Green Furnaces.
