Understanding Gas Furnaces: Types and Models

Gas furnaces are integral to maintaining comfortable indoor temperatures, especially during the cold BC winters. They use natural gas or propane to heat air, which is then distributed throughout the home via a duct system. Here’s a detailed look at the types of gas furnaces available:

Types of Gas Furnaces

  1. Single-Stage Furnaces
    • Operation: Single-stage furnaces have a simple on/off operation. They run at full capacity when heating is required and shut off once the desired temperature is reached.
    • Efficiency: These furnaces are less efficient compared to multi-stage models, as they do not modulate their output based on demand.
    • Best For: Homes with consistent heating needs and those looking for an economical option.
  2. Two-Stage Furnaces
    • Operation: Two-stage furnaces can operate at two different levels of heat output—high and low. The low setting is used for most of the time, while the high setting is reserved for extremely cold conditions.
    • Efficiency: These furnaces offer better energy efficiency and more consistent indoor temperatures.
    • Best For: Homes in regions with fluctuating temperatures and those seeking enhanced comfort and efficiency.
  3. Variable Speed Furnaces
    • Operation: Variable speed furnaces use an electronically commutated motor (ECM) that adjusts the blower speed to match the heating demand.
    • Efficiency: These furnaces provide the highest energy efficiency, superior comfort, and quiet operation.
    • Best For: Homeowners looking for the best in energy savings, comfort, and noise reduction.
  4. Modulating Furnaces
    • Operation: Modulating furnaces can adjust their heat output in small increments, providing precise temperature control.
    • Efficiency: These are the most efficient gas furnaces, maintaining a constant and even temperature throughout the home.
    • Best For: Homes where maximum energy efficiency and comfort are priorities.

Gas Usage Calculations for BC Homes

Understanding gas usage is crucial for managing heating costs and ensuring efficient operation. Here, we’ll break down the gas usage calculations for BC homes, providing three different scenarios.

Basic Calculation Method

The basic formula for calculating gas usage in a furnace is: Gas Usage (BTUs)=Furnace Input Rating (BTUs/hr)×Operating Hours

  1. Furnace Input Rating: This is the amount of gas energy the furnace uses per hour. It is usually listed on the furnace’s nameplate.
  2. Operating Hours: The number of hours the furnace runs.

Scenario 1: Small Home

  • Home Size: 1,200 square feet
  • Furnace Input Rating: 60,000 BTUs/hr
  • Operating Hours per Day: 8 hours

Daily Gas Usage: 60,000 BTUs/hr×8 hours=480,000 BTUs

Monthly Gas Usage (assuming 30 days): 480,000 BTUs/day×30 days=14,400,000 BTUs

Scenario 2: Medium Home

  • Home Size: 2,000 square feet
  • Furnace Input Rating: 80,000 BTUs/hr
  • Operating Hours per Day: 10 hours

Daily Gas Usage: 80,000 BTUs/hr×10 hours=800,000 BTUs

Monthly Gas Usage (assuming 30 days): 800,000 BTUs/day×30 days=24,000,000 BTUs

Scenario 3: Large Home

  • Home Size: 3,500 square feet
  • Furnace Input Rating: 100,000 BTUs/hr
  • Operating Hours per Day: 12 hours

Daily Gas Usage: 100,000 BTUs/hr×12 hours=1,200,000 BTUs

Monthly Gas Usage (assuming 30 days): 1,200,000 BTUs/day×30 days=36,000,000 BTUs

Types of Gas Used in Furnaces

Gas furnaces primarily use two types of gas: natural gas and propane. Each type has its own characteristics, advantages, and considerations.

Natural Gas

  • Source: Extracted from underground reserves and delivered through a network of pipelines.
  • Cost: Generally less expensive than propane, making it a popular choice for urban and suburban areas with established gas lines.
  • Efficiency: High-efficiency natural gas furnaces can achieve AFUE ratings of 90-98%.
  • Environmental Impact: Cleaner burning compared to other fossil fuels, producing fewer pollutants.

Propane

  • Source: A byproduct of natural gas processing and petroleum refining, stored in tanks and delivered by truck.
  • Cost: Typically more expensive than natural gas but can be more economical in areas without natural gas infrastructure.
  • Efficiency: Propane furnaces can achieve similar high-efficiency ratings as natural gas furnaces.
  • Environmental Impact: Produces more carbon dioxide per unit of energy compared to natural gas but still cleaner than many other fossil fuels.

Common Errors and Leaks in Gas Furnaces

Gas furnaces, like any mechanical system, can experience issues that affect their performance and safety. Here are some common errors and leaks to be aware of:

Common Errors

  1. Ignition Failures: Issues with the ignition system can prevent the furnace from starting. This could be due to a faulty ignitor, sensor issues, or problems with the gas supply.
  2. Thermostat Malfunctions: If the thermostat is not working correctly, it can cause the furnace to operate inefficiently or not at all.
  3. Dirty Filters: Clogged air filters reduce airflow, making the furnace work harder and less efficiently.
  4. Blower Motor Issues: Problems with the blower motor can affect the distribution of heated air throughout the home.
  5. Flame Sensor Problems: A dirty or malfunctioning flame sensor can cause the furnace to shut down as a safety precaution.

Gas Leaks

Gas leaks are a serious issue and can pose significant safety risks, including fire and carbon monoxide poisoning. Common signs of a gas leak include:

  • Rotten Egg Smell: Natural gas and propane are odorless but are treated with a chemical that gives them a distinctive sulfur-like odor.
  • Hissing Sounds: A hissing sound near the furnace or gas lines can indicate a leak.
  • Dead Plants: Vegetation near gas lines that suddenly dies can be a sign of a leak.
  • Higher Gas Bills: An unexplained increase in gas usage may indicate a leak.
