Gas Furnace Installation: Which Type Should You Choose?

The truth is, furnaces go largely unnoticed for a large part of the year, getting on with their job quietly in the background while other home appliances take centre stage. However, as soon as the temperatures start to drop here in Toronto, suddenly the spotlight is cast on the furnace and it becomes the most important appliance in the entire household. If the efficiency of your furnace has declined in recent years or it is simply so old that it cannot compete with the technology today’s models are equipped with, it might be time for a new furnace installation. A replacement is also a good idea if your furnace constantly requires repairs.Trane Furnace

The Main Types of Gas Furnace Installation

Furnaces are categorized in various different ways. Firstly, you need to select the fuel source you would like your furnace to run off. In this article we are discussing furnaces that use gas, but there are various others you can choose from such as oil and electric. Nearly every gas furnace installation you come across will fall into one of the two following categories:

  • Conventional Furnaces – The energy efficiency rating (under 90%) this type of furnace installation is able to achieve is inferior to those possible with condensing furnaces. This is because the gases leave the combustion chamber very quickly and allow very little time for the heat exchanger to gather heat before it is distributed. The waste gases are removed from your home through a vertical vent that is attached to the furnace. These furnaces are no longer available for sale in Canada.
  • Condensing Furnaces – If you purchase a gas furnace, it’ll almost certainly be a condensing style furnace, which cools and condenses waste gases rather than removing them quickly. Additional heat is extracted from these gases, allowing the furnace to operate at higher energy efficiency levels. Owing to the fact these gases aren’t simply disposed of immediately, there are two heat exchangers to ensure the waste gases are kept separate as they cool and condense.

These two main categories of gas furnace installation are then broken down further into three subcategories that differ from one another in the way that two of the main components function — the blower and the burner.

  • Single Stage Furnaces – The least efficient of the three types of furnace installations, largely due to the fact that there are only two settings: on and off. This means that once the room temperature in your property drops below a certain level, the ignition will kick in and heat your home. They represent the most economical choice, but they also waste a lot of energy and can bump up your energy bills.
  • Two-Stage Furnaces – The way these furnaces operate is a little more complex than the bare-bones single stage option, as the flame can be put on a number of different settings. This allows the furnace to better regulate your property’s temperature and avoid the constant fluctuations associated with single stage furnaces.
  • Modulating Furnaces – This is the most energy efficient choice as the flame is adjusted far more precisely, often in increments of just a single degree, which produces a constant temperature, unlike the other two options. This results in a more comfortable home environment and some modulating furnaces can achieve an energy efficiency rating of 98%. You should be aware though that they often require a considerable investment when compared with the two other options.

While this was only a brief introduction into some of the types of furnace installation that you could potentially have fitted at your home, we hope it benefited you.
