How a furnace works
A furnace draws air from a home into a duct work system. The air is taken to an area where it is warmed before the warm air is delivered throughout the house. Newer furnaces usually rely on the use of blowers to recirculate the warm air. The circulating air is often drawn through a filter. This helps rid a house of dust as well as other particles.
A furnace blows the heated air through the ducts that help in the delivery of warm air to the rooms through air registers or grills. This type of heating system is commonly referred to as a forced warm-air distribution system. A furnace may be fueled or powered with gas, oil, electricity, wood, or coal. Vents help to bring warm air into living spaces. These vents are usually found in walls or floors and the temperature is often controlled through an adjustable thermostat
What is the Cost of a Furnace?
The cost can depend on many variables such as local climate, location, unit type, size of home, the brand of the unit, the quality of the install—the list goes on. For instance, your furnace installation may increase if your home needs extensive electrical or duct work.
Also, depending on where you live, certain towns may need a permit for a furnace installation. This can vary in price from as little as $50 to hundreds of dollars. Please also keep in mind that an expectation may need to be completed by the municipality or city. It’s always best to check on your local bylaws.
As a general rule of thumb, when purchasing a furnace, the cheapest option isn’t always the best. We know—cheaper ones are rather tempting. However, your furnace has a significant duty to maintain your family’s comfort within the home.
Types of Furnace
1-Freestanding Furnaces
This is the most common in all types of furnaces. They have a firebox, which is where you put your fuel or wood to create an open flame that heats the air inside the furnace. The more efficiently it does this, the better off your house will be in terms of being warm and cozy during those cold winter nights.
2-Wall-Mounted Furnaces
This type of furnace is the cheapest option to install. Also, it is easy to maintain, and most importantly it does not need any clearance around its sides, which makes installation very simple. However, if you are looking for a unit that can heat your entire home or business this might not be the right choice because these units cannot provide enough heat depending on their thermal unit rating.
3-Floor Standing Furnaces
Floor standing furnaces are the most popular type of furnace. They are also known as vertical furnaces or step-down furnaces. Floor standing units have to be installed in a pit that is about one meter deep, and it has to be at least 30 cm wider than the furnace.
