What Is A Furnace? How Does it Work?

A furnace, also known as a boiler or heater in English, is an internal heating device used to heat a building. A modern furnace is usually used as part of a centralized heating system; the term derives from the ancient Greek word fornia, meaning furnace.

 

Most common type of furnace

The most common type of furnace is a gas furnace. They are available with both direct and venting system. In venting system, the gas that is burned by the furnace passes through a vent pipe; the air is then blown by a vent fan. In this case, a furnace vent can be either open or closed depending on the need.

The direct system, on the other hand, works by heating the air directly. This is usually the most economical choice. The heat source in this case is the burning of fuel oil, wood, or coal. The resulting air is then pushed to ducts that are connected to the house. From there, it is then blown into the house through the chimney or vent.

In this method, a furnace is used to provide heat for all the rooms of a building and is usually placed near the central heating system so that the furnace can also act as an air conditioner. Since this type of furnace is placed close to the house, the temperature inside may get affected by outside conditions. Thus, a person living in this kind of area should consider buying an air-conditioning system in order to effectively control the temperature of the room.

A more expensive method of furnishing buildings is to use a combination of indirect heat and a furnace. In this case, a heat pump is used instead of gas furnace. It acts as an energy storage unit; it collects excess thermal energy from the outside environment and converts it to heat by way of heating water in the same. In this case, it acts like a battery.

A heat pump can be installed in the ceiling or floor of the room that needs heating; or alternatively, a duct may be run from the wall or the furnace itself so that the heat pump can be placed somewhere else. It is very effective when heating a room in a large building. Since the heating pump is the source of energy that is being used to warm the air that is blown into the room, it takes less space than a gas furnace and it also has a much longer lifetime.

To be able to use a furnace as an energy saving device, the furnace should be located close to the central heating systems in order to have a direct line of air with the heat pump. This makes it easier for it to operate and maintain the optimum efficiency level for a room. Also, since the furnace is situated near the house, it will not affect the efficiency level if it is not operating at its maximum capacity. The heat pump can be used in the same way as the gas furnace; the main difference here is that a furnace does not need to be turned on to turn on the heat pump.

Benefits of Using Heat Pump

Another benefit of using a heat pump is that it does not produce any noise. Since it is placed near the house, it is quiet enough to be used without disturbing anyone; it is also not needed to be vented. The furnace can be shut off or moved if there are problems, while the heat pump, on the other hand, needs to be turned on manually.

If you need a more permanent solution to controlling the heating and cooling of a room than the heat pump, you may decide to install a furnace as well. However, if you want to get rid of the furnaces, the best solution is to make some changes to the structure and plumbing of the room so that it is able to provide the right amount of heat and cool air.

This means changing the insulation and heating elements of the house; this would make it more efficient and energy saving. You can also choose to switch the furnace with the heater. this change; the furnace would then become part of the central heating system. and the heat pump would become the source for controlling the heat.

If the space where you want to install the furnace is large enough, the furnace would need to be placed on the ceiling or the roof; this is because the heat and cool air cannot escape through the walls. The air-conduction part of the furnace is placed in the attic, while the fan is installed in the room opposite to it; if the fan is placed on the floor, the room would get less air circulation. In addition to that, the furnace could be put in the basement to make use of space that would otherwise be wasted in order to heat the home.
