Forced Air Heating

Forced air heating is generally considered one of the most common heating systems used in residential and commercial buildings. It’s a must-have household in Ottawa and even in North America where people spend ~$1200 annually just on heating systems. Do you know why?

As the world becomes more conscious of the environmental impact of our daily activities, it is essential to evaluate the eco-friendliness of various systems and technologies we use, including heating systems. One commonly used heating method is forced air heating, which involves distributing heated air throughout a building using ducts and vents. 

However, is forced air heating truly eco-friendly? In this article, we will delve into the topic and explore why this air heating system can be considered an environmentally friendly heating option. So, let’s move!

What is Forced Air Heating?

In simple words, forced air heating systems comply with air to direct heat into the homes. It mainly utilizes a system of ducts and vents to deliver heated air to different rooms or areas within a building. The heart of the system is the furnace, which is typically powered by electricity, natural gas, propane, or oil. 

The furnace heats the air, which is then propelled through the ductwork by a blower fan. The warm air is released into the rooms through registers or vents, providing a comfortable indoor environment during cold weather.

How Forced Air Heating System Work

The overall forced air heating system relies on its particular components and working principles that run the whole mechanism efficiently. For their details, see below! 👇

Components of A Forced-Air Heating System

Mechanism of forced air heating

Typically, there are FOUR components that work in the forced air heating system. These are;

Furnace

The furnace is the central component of the forced air heating system. It contains a heat source, such as a burner or heating element, and a blower fan. The heat source warms the air, and the blower fan circulates it through the ductwork.

Ductwork

The ductwork consists of a network of metal or flexible tubes that carry the heated air from the furnace to different areas of the building. The ducts are usually hidden behind walls, floors, or ceilings, and they distribute the air to various rooms through registers or vents.

Air Filter

Forced air heating systems often incorporate an air filter to remove dust, debris, and allergens from the air before it is heated and circulated. The filter helps maintain good indoor air quality and prevents the accumulation of dirt in the ducts and the furnace.

Thermostat

The thermostat is the control center of the heating system. It allows the user to set the desired temperature, and it signals the furnace to turn on or off based on the temperature readings. Modern thermostats can be programmed to adjust the temperature automatically according to the user’s schedule, helping to optimize energy consumption.

Working Principle

The operation of a forced air heating system can be summarized in a few simple steps:

Step1: Heat Generation

The furnace is ignited or turned on, activating the heat source. The heat source can be a burner that ignites fuel, an electric heating element, or a heat exchanger that transfers heat from a combustion process.

Step2: Air Circulation

As the heat source warms up, the blower fan is activated. The fan draws air from the room into the furnace, where it passes through the heat source. The air absorbs the heat and becomes warm.

Step3: Filtration

Before the warmed air is distributed throughout the building, it passes through an air filter. The filter removes dust, pollen, pet dander, and other particles, ensuring clean and healthy air.

Step4: Distribution

The warm air is pushed by the blower fan into the ductwork. The ducts carry the heated air to different rooms or areas of the building. The air is released through registers or vents, providing a consistent and comfortable temperature in each space.

Step5: Temperature Regulation

The thermostat monitors the temperature of the air in the building. If the temperature falls below the set point, the thermostat signals the furnace to activate and start the heating process again. Once the desired temperature is reached, the thermostat shuts off the furnace, conserving energy.
