If you are thinking about replacing your old furnace in Toronto, consider a gas furnace as opposed to an electronic counterpart. Gas furnaces are more energy efficient and are the furnace of choice due to their economical status..
Natural gas furnaces of today are available with high-efficiency and an Annual Fuel Utilization Efficiency (AFUE) of 90 percent or higher. Although, there are a few things homeowners should consider before deciding on the type and size of the heating unit for their home’s needs.
The primary thing to consider is the size and square footage of your home, including the number of floors and layout of the house. This will impact the size and type of furnace that will work to keep your home comfy and warm. Energy Star certified models are also worth considering since they meet certain efficiency standards and will mostly qualify for government rebates.
There are mainly 3 types of gas furnace systems:
- This is the most common type seen in the market. Its systems feature gas valves that are either open or closed. When it is open the gas only flows at a high rate, so this is not the most energy efficient option. Most furnaces of this type have an annual fuel utilization efficiency (AFUE) of 80%, which is an improvement from older models, but not the best on the market now in terms of energy savings.
- Two-stage furnaces are more flexible with the amount of gas they use for the heat requirement. There are two open positions instead of one- partially open and fully open. The flow is chosen based on the adje=ustments made on the thermostat. These types of furnaces can be expected to have an AFUF of about 90%.
- Furnaces with a modulating gas valve are able to adjust the heating output from 35% to 100% of the capacity, and are able to most accurately regulate the amount of fuel used. A modulating furnace is able to modulate the heating output by 1% for your homes specific needs. High quality modulating furnaces offer the most energy efficiency as well as improved air distribution and flow.
New and updated furnace features are import to consider in your decision making:
Variable Speed Blower Motors
- A blower motor with variable speeds can control circulation to temperature demands automatically. This feature uses 60%-75% less electricity, lasts longer than standard blower motors and is much quieter than its counterparts.
Energy-Saving Electronic Ignition
- Today’s gas furnaces have become much more energy-efficient. Pilot lights on older furnaces have been replaced with electronic ignitions and the burner will only start when the thermostat calls for it.
- Zoned heating and cooling systems divide your home into different areas or “zones” and use different thermostats to adjust different temperatures for each zone. This method means no more hot or cold spots and individual preference for different room’s temperatures.
As cost of living has increased within the last decade, natural gas prices have stayed low. Natural gas is a clean, safe and reliable option. Additionally, an abundant supply means that it is the most affordable energy fuel and most valuable for your dollar.
