Furnace Buying Guide for 2023
The pandemic and work-from-home culture make Canadians stay home more than ever. Thus, the dependence on the HVAC system has increased. A reliable furnace can work hard all day long. This guide is a lifesaver if you are shopping for a new furnace. It covers all your brand, cost, fuel type, fan speed, and other questions.
What is a furnace?
A furnace is an HVAC system that blows warm air through a ventilation system and keeps the house warm during winter. It needs fuel such as natural gas, propane, electricity, or oil to produce heat. It’s difficult to get through the harsh winters without a working furnace.
How does a furnace work?
A furnace’s main components include a thermostat, burners, heat exchanger, blower motor, ductwork, and ventilation. All these components work together to keep you warm during winters. A step-by-step working of a furnace is as follows:
Step 1: As soon as the temperature drops below the desirable number set by you, the thermostat detects it and sends a signal to the furnace to activate other components.
Step 2: Upon receiving a signal from the thermostat, fuel is released to ignite the burners. The flames of all the burners heat up the metal heat exchanger.
Step 3: A blower circulates air over the heat exchanger to warm it up.
Step 4: After the air has warmed sufficiently, it is circulated throughout the ductwork by a fan. Warm air flows through various vents into your house to attain a desirable temperature.
Step 5: Once your house attains the right temperature, a furnace will shut itself off. The process of heating will repeat when the temperature falls again.
This guide discusses all the information required to buy the right furnace for your home. Here’s everything you need to know, brands, types, costs, and sources.
How to choose a fuel type for your furnace?
Choosing propane, oil, gas, or electric furnaces depends upon many factors such as area, budget (capital and operating), weather, climate, and level of heat you need. Where a natural gas pipeline facility is readily available, choose a gas furnace. Otherwise, propane is better than oil and electricity. Electric furnaces make a great choice for areas where electricity is cheap.
A more detailed analysis of different fuel types is as follows:
Natural Gas Furnaces
The most widely used heating source in Canadian homes is gas furnaces. They disperse heat evenly throughout the houses. In comparison to other furnaces, they are a bit expensive to install. But their higher efficiency and effectiveness make up for it. Higher efficiency and lower wastage results in low utility bills. They can cause carbon monoxide leaks, making the installation of detectors necessary. They are better suited for colder areas like Canada. Its AFUE rating can go as high as 98% in new furnaces.
For rural areas where gas connections are not readily available, propane furnaces are a good choice. These furnaces use propane as fuel. Propane is a result (byproduct) of oil refinement and natural gas processing. Since these furnaces have a large tank, they need a large area for installation. One of the biggest disadvantages of propane furnaces is the need to refill the tank frequently. Propane is one of the cleanest fuel options. Such furnaces last longer. Its AFUE rating ranges between 80-95%.
Oil furnaces use oil to ignite burners and warm up the house. They are less efficient in comparison to gas furnaces. You may choose an oil furnace if you have a small budget and a lot of space for an oil tank. Its upfront cost is low, but oil is more expensive than natural gas. Apart from being expensive and less efficient, it also needs frequent maintenance. Its AFUE rating ranges between 80-90%. To know more about an oil furnace, click here.
Electric furnaces, as the name suggests, use electricity to produce heat. In comparison to gas furnaces, electric furnaces are cheaper to install. Unlike gas furnaces, they take some time to produce heat. When it comes to electric furnaces, electricity per unit is an important factor to consider. Using an electric furnace may make sense if electricity is cheap and gas pipelines cannot be connected. With proper maintenance, these furnaces can last for as long as 30 years. Electric furnaces’ carbon emission is low.
|Basis||Natural Gas Furnace||Propane Furnace||Oil Furnace||Electric Furnace|
|Operation Cost||Low||Higher (Almost double the cost of natural gas furnaces)||High||Quite High (Four times more costly than a natural gas furnace)|
|Tank||No tank||It needs a tank.||It needs a tank.||No tank|
|Lifespan||15-30 years||16-20 years||16-20 years||20-30 years|
|AFUE rating||As high as 98 %||80-95%||80-90%||As high as 100%
