Since 2010, mid-efficiency furnaces have been phased out in Canada and replaced with high-efficiency furnaces. This means that Canadians can now only buy high-efficiency furnaces for their homes. There are three main types of high-efficiency furnaces to choose from.
Here is a quick guide to understanding the difference between the types of high-efficiency furnaces.
A single-stage furnace can only be set to either “on” or “off” and nothing in between. Because these furnaces are at full flame when they are turned on and do not have a lower setting, they are not as efficient as some other models. However, single-stage furnaces are also the most affordable option up front when it comes to condensing furnaces.
A two-stage furnace can be set to “off,” “low,” or “high,” giving you more control over the temperature in your home and the amount of energy that your furnace is using when it is turned on. Because of this, two-stage furnaces result in lower monthly bills than single-stage furnaces and deliver more comfortable, consistent temperatures, however they do cost a bit more.
A modulating furnace automatically increases or decreases the heat level automatically, depending on the temperature of your home. These furnaces are able to adjust the temperature by small increments, so they produce the most effective temperature control. They are also quieter than other units because they adjust throughout the day as opposed to turning off and on noisily. Modulating furnaces are the most expensive type of furnace to purchase up front, but they are also the most efficient and save you the most money on bills in the long term.
