Gas furnaces are an affordable heating source that has been used for decades. However, there are several things to consider when choosing a gas furnace. Here are answers to common questions regarding gas heat and cost savings.
Gas Furnace System
You need to provide fuel for a gas furnace to operate correctly. Fuel consists of either propane or natural gas. Natural gas has been proven to be safer than using propane, but there are still risks involved when using these fuels.
While most Americans would say that wood stoves burn logs, and electric heaters run off of electrical outlets, the truth is that gas furnaces don't really use any electricity at all. This article explains how a gas furnace works and shows how much electricity they use.
What is the difference between electric and gas furnaces?
Natural Gas Furnace
Gas furnaces are designed to conserve energy, prevent overheating, and thus avoid damage. They usually cool themselves without the help of fans or blowers. The fan motor turns on automatically when the temperature reaches certain levels. If the heater gets too hot, the pilot lights go out, and the fan shuts down.
Typically, a gas furnace uses 1.5 to 2 times more fuel than an electric heating system. However, a gas furnace costs 30 percent more than an equivalent electric unit. A gas furnace uses slightly more electricity to operate than an electric furnace.
Electric Heater
An electric heater runs off of electricity supplied from your power source. Electric heaters are typically used in areas where temperatures drop below freezing. An electric heater takes longer to warm up than a gas furnace, and its air circulation tends to blow colder air indoors.
A typical electric heater wastes about 40 to 50% of its energy. In addition, an electric heater uses one to two times more electricity than a gas furnace, although the cost savings over a lifetime may justify installing a gas heater.
Cost Estimates
Depending on where you live, the price tag for a gas furnace may range between $800 and $1500. The average price for an electric heater ranges from $500 to $1000. Both types of appliances last 10 to 15 years.
As part of your annual maintenance plan, remember to change your filters every month - ideally, three months before changing your entire filter system. Even if you have central air conditioning, opening the windows allows fresh air inside to circulate.
Make sure that you keep track of how many hours of operation per week each piece of equipment receives. In addition, record the amount of energy consumed per hour. Over time, these numbers should tell you whether your appliance is operating efficiently.
If possible, choose a brand name model with the highest rating from Consumer Reports.
Frequently Asked Question
Who should install a gas furnace?
For those living in colder climates, installing a gas furnace may save them money over an electric one. According to the U.S. Department of Energy, installing a gas furnace can save consumers $300 per year on average.
Why do I need to change my existing boiler?
Before switching to a gas furnace, ensure that your boiler is operating properly. If your old boiler is not working correctly, you will incur unnecessary expenses such as repair costs or replacement parts. Furthermore, if your boiler is damaged beyond repair, you may have to purchase an entirely new unit rather than simply changing the burner.
Do I need to drain the boiler?
It is recommended to drain the boiler before installation. Drainage systems allow the removal of any gasses or liquids which may cause a buildup of pressure in the system. In addition, it ensures that your pipes aren't compromised and the unit won't burst.
Should I invest in a humidifier?
Humidifiers help regulate indoor air quality, especially in dry regions. Humidity levels below 60 percent raise respiratory health risks for individuals with asthma and allergies. A humidifier helps keep humidity levels within normal ranges.
Are there advantages of investing in a variable speed blower? A variable speed blower provides better airflow control and efficiency than standard blowers. In addition, because the fan blades spin faster at low speeds, the unit uses less power. As a result, it translates into lower utility bills.
Can I buy a pre-engineered unit?
Some manufacturers offer pre-engineered units to minimize construction time. Pre-engineered units generally consist of components that are manufactured separately and assembled. Components include fans, ductwork, heat exchangers, controls, and filters.
Is it safe to leave the house without turning off the gas supply?
Leaving a building unattended with a running heater or oven is perfectly fine. The National Fire Protection Association recommends following these safety tips when using appliances near open flames. Never leave children alone in the room with an appliance. Be careful where you place flammable items in case of a potential accident. Remember, open flames can create a hazard anywhere, even.
