Factors affecting gas usage

Gas costs can have a major impact on how much gas a furnace consumes. But there are other things that could affect gas usage, too! Consider:

  • Size of the home: Bigger homes use more heat so they’ll use more gas. Insulation quality, windows, and remodeling can also add to monthly usage.
  • The efficiency of the furnace: Gas furnaces have an AFUE rating that shows how well they turn fuel into heat. High-efficiency furnaces use less gas.
  • Type of fuel: Natural gas is usually cheaper than propane, making it the better choice for space heating. Propane is usually used for water heating.

Hot water consumption, electricity usage, the number of appliances, and even the weather can all affect monthly energy costs. Making conscious choices can help reduce costs in the long term.

To maximize efficiency, take regular readings of your utility bill or use an online cost calculator. This will help you budget wisely and save money over time.

Don’t forget to consider these factors affecting gas usage when assessing your furnace’s efficiency!

Types of gas furnaces

Gas furnaces come in various models and types. It’s important to choose the right one for your requirements, budget, and energy efficiency needs. Here’s some info about the types of gas furnaces to help you make an informed decision.

Single Stage80-94%≤90%
Multistage or Modulating>97%>96%

When selecting a gas furnace, consider the size of your house. Check how many BTUs (British Thermal Units) your furnace produces per hour and compare it to the cubic feet per minute (CFM) your house requires. Also, factor in any gas appliances like water heaters or fireplaces in your home.

It’s recommended to work with an HVAC contractor when selecting a new gas furnace. They’ll check the necessary sizing calculations and provide an invoice for total project costs. Plus, replacing old windows, improving insulation, or upgrading appliances may be worth considering to maximize energy usage. Gas prices may change but the cost of keeping your home warm is always important.

Gas prices and costs

Gas costs and their usage for heating can be worrisome. Most households in colder climates rely on natural gas, propane, or fuel oil furnaces to stay warm. But the expenses depend on the quality and efficiency of your furnace, the size of your home, plus outside factors like rising gas prices and old windows/doors lacking proper insulation.

Homeowners must look at their monthly operating expenses (electricity used by appliances) and other unexpected expenses. Natural gas ranges from 28-39 cents per therm while propane is $3-4 per gallon. Estimate your usage costs by calculating the BTUs needed for space heating (55 BTU/sq.ft) and hot water heating (23 BTU/sq.ft). then multiplying the numbers by your usage hours. December to February will likely have higher consumption.

The data on gas prices and consumption can help homeowners when budgeting or remodeling. For instance, switching from an electric furnace to a gas could save hundreds a year because high AFUE rate furnaces use less fuel.

Keep in mind geography and materials used to build your home also affect energy usage. To stay energy-efficient during winter, check your model number or utility invoice/details. This way you get valuable insight into maximizing energy efficiency all year.

Heating and hot water usage

Heating and hot water usage in a home have many factors. Size of the house, type of furnace, energy source, and efficiency all matter when deciding on gas or propane use and cost. A 2,000 sq ft house with a gas furnace could use 500-1,200 cubic feet of gas per month, depending. On the other hand, a propane gas fireplace may use 1 gallon of propane per hour. Natural gas prices are $1-$1.50 per CCF (hundred cubic feet) or $10-$15 per MMBTU (million British thermal units).

Old appliances or windows can increase energy use and cost. Replacing old single-pane windows can cut heating costs by 25%. Hot water usage is 18% of total energy use. Usually, a household uses 40-60 gallons of hot water daily. In Missouri, the propane cost for space heating is $2.00-$2.50 per gallon.

It’s smart to budget for heating and hot water costs or plan a remodeling project. Cost calculators or HVAC professionals can give accurate calculations. Understanding energy use and efficiency can save money and resources. 

Gas or electric furnace? It’s a choice between a Ferrari or a Prius, depending on your needs.

Comparison of gas and electric furnaces

Gas and electric furnaces are both cost-effective and efficient for space heating. A gas furnace uses natural gas or propane as its energy source. An electric furnace works with electricity.

Here’s a comparison chart to help decide:

Heating capacity30000-120000 BTU10-26 KW
Lifespan15-20 years20 years+
MaintenanceOnce a yearNone required
EnvironmentCombustion gasesZero-emission

Installing a gas furnace is more complex than an electric one, due to the venting and ductwork requirement. Also, consider fuel sources available for natural gas or propane in the area. Propane tank delivery and storage take extra space and attention.

The average price per therm for natural gas in New York State in Oct 2021 was USD cents 97.7 per CCF or cubic foot multiplied by therms used with an AFUE rating of around 90%.

Maintaining a gas furnace is like keeping a car running – don’t wait until it breaks down.

Gas furnace maintenance and repair
