A heater makes a room warmer by convection currents . The cold air comes down to get heat from heater and warm air (convection currents) lifts up in the room . If heater is placed at a height , then cold air below this height will not be heated by heater therefore it is installed near he floor of room.
Put your space heater on the floor and leave it there
Don't set it on a shelf or a stool or a dusty wooden workbench in the basement. And definitely don't put it on top of your bed, with all those flammable fabrics and feathery fillings.
The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. If it is placed near the floor then it will fill just the bottom of the room with cool air.
To maximize the efficiency of a space heater, it is important to place it where air can circulate freely. Avoid placing it in corners, behind furniture, or under curtains. Safety: Space heaters should always be placed on a level, stable surface, away from flammable materials such as curtains, bedding, and furniture.
Given basic physics of heat rising and cold sinking, if you put an A/C Unit near the ceiling and a heater near the floor, it helps the cold/warm air circulate better.
Floor registers are ideal for efficient heating
Warm air rises from the floor and heats the room. However, if you place your registers on top of the ceiling, most of your warm air will find its way to the upper portion of the room, where it will only do a little good.
Keep Away From Other Heat Sources
Placing your AC near heat sources will prevent it from running efficiently. Heat sources such as lights bulbs, refrigerators and TV's can cause the unit's sensor to read the wrong temperature and will make the system work harder than it needs to.
An estimated 25% of all heat loss occurs through the attic or roof of a home. Cracks or holes in an attic, along with improperly placed vents, allow for significant amounts of heat loss through the attic space. In addition, improper ventilation in attics leads to even more heat escaping.
Q: Where is the heater located in a house? A: If you have a furnace, it is typically located centrally in the home. Areas to check could be a utility closet, garage, attic or basement. If you have a heat pump, it would be located outside of the home.
When radiant heating is located in the floor, it is often called radiant floor heating or simply floor heating. Radiant heating has a number of advantages. It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses.
Furnaces Need a Good Foundation
First and foremost, furnaces should be placed on rubber pads to minimize the noise they make. Then, if they happen to be located in the basement, they should be propped up on blocks or something else that keeps them at least four inches off the floor in case the basement floods.
Counter Heat Loss
Placing radiators under windows is a practice adopted to help counteract the cold air that can enter a room through the glass.

Running a space heater overnight increases the risk of fire. If the unit is left unattended or placed too close to flammable materials, such as curtains or bedding, it can ignite and lead to a devastating fire.
Radiant floor heating offers a comfortable, efficient, and invisible way to heat your home. While the upfront costs may be higher than traditional forced-air systems, the potential energy savings and increased comfort make it an attractive option for many homeowners.
How much heat is lost through my floor? It may surprise you to know, on average, 10-20% of heat loss occurs through your floors – this is in addition to losing heat through your ceilings, windows, and doors, not to mention open fireplaces too.
Minimum Heat Setting for an Empty House
The minimum temperature setting is between 55 and 60 degrees. Setting the indoor temperature below 55 degrees in the winter could cause problems.
The ocean is the largest solar energy collector on Earth. Not only does water cover more than 70 percent of our planet's surface, it can also absorb large amounts of heat without a large increase in temperature.
Keep the Space Heater on the Floor
The main reason to keep your space heater on the floor is that it's safer. While it may be tempting to keep your heater on a higher surface, so the heat blows toward your face, it can easily tip over and cause an accident.
Electric heaters work best when they heat up a confined space, such as the area around a desk or a reading chair. Take a look around your room and decide where your heater will be most useful. It may also help to choose an area that can be closed off by doors, so you can better trap in the heat.
Heaters are best placed under windows. If you do not have the space for panel heaters, you can also choose wall strip panel heaters, which are lower and longer variants. By placing heaters under the windows, you heat up cold air descending from the window glass, and avoid cold draughts along the floor.
In a room it is best to place a room heater on the floor but an AC near the ceiling because heater produces hot air which rises up making the air in the room warm whereas AC is usually used in summer to keep the air cool and is placed near the ceiling so that the cold air spreads in the room making it cool.
Typically, we find unit heaters mounted about 8′–10′ off the floor in a room with 14′–26′ (or higher) ceilings. In most of these cases the heater is a horizontal flow heater mounted so that the air is basically blowing horizontally, or at best at a 10–15 degree angle.
The Ideal Temperature for Maintaining Your Air Conditioning
Minimize frequent cycling (turning on and off) to reduce stress on AC unit components. It is recommended to set the thermostat setting between 65–80°F for optimal performance and to keep those cooling bills minimal.
