How Does a Furnace Work?

If you live in a town like Ajax, furnace systems are probably an integral part of your home. Gas and oil furnaces are a versatile and inexpensive way to create heat in the cold of winter. When combined with a well-insulated home and regular maintenance they can offer you a warm and cozy environment for many years to come. As common as furnaces are, however, comparatively few people understand the principles involved. How does a furnace work? Read on for the answers.

Most furnaces are centralized systems, which means they use a series of ducts to distribute air to your home. When your thermostat detects the temperature you set for it, it ignites a burner inside the heater’s combustion chamber, which lights a steady flow of gas. The heat then moves into a heat exchanger, which warms the air. A blower pulls the air through the exchange and into the duct system, which then distributes it throughout the entire house.

It’s a comparatively simple system, though that doesn’t stop it from experiencing problems from time to time. Furnaces rely on air filters to keep dust and debris from building up inside of it. The filter needs to be changed frequently (or cleaned if it’s a permanent filter). Otherwise, the dust will build up in your system as well as spreading throughout your home via the ducts. Dust increases friction in the heater’s moving parts, which cuts down on efficiency and increases strain on the system. A regular maintenance session from a trains professional can address these problems, while reducing the risk of more serious repairs in the future.
