Quick Answer: How Many Amps Does A Furnace Blower Draw

Typically, a standard blower fan needs on average 400 watts of electricity. This means that it needs a 15-20 amp circuit. However, depending on the size of your furnace, the amount of needed power could be 20 amps or more.

How many amps does a furnace blower motor pull?

Up to 20 Amps or more. Amperage is how much power a device is consuming. The Amps will be labeled on the motor’s name tag.

How many watts does a furnace blower use?

How Many Watts Does a Furnace Blower Use? It depends on whether or not you have a standard fan motor or if you’re operating with a variable-speed motor. The standard is about 400 watts per hour, but the high-efficiency variable-speed models can deliver at about 75 watts per hour!.

How much electricity does a furnace blower motor use?

Variable Speed Furnace Fans A standard fan motor will typically use about 400 watts per hour while a variable-speed model will only use 75 watts per hour. This is the most direct way that the variable-speed units save electricity, but there are other means by which they affect energy usage as well.

How much power does a furnace draw?

A typical gas furnace usually requires a small amount of electricity to start and operate in your home. Most gas furnaces use less than 600 watts of electricity to run. So to run a gas furnace for 2 hours per day, will cost us around $0.156 with the average price of electricity in the U.S. that is 13 cents per kWh.

How many amps does a propane furnace draw?

Now, we know that the blower fan on the furnace draws up anywhere between 10 to 12 amps per hour. This means that the heater can run non-stop for a little over 12 hours. However, for safety reasons, it’s recommended that you don’t keep the heater running all that time.

How many amps does an oil furnace draw?

You main draw is your burner, which (depends on the brand) will draw a starting wattage of around 7-10 amps, then settle down to between 2-5 amps. Your whole system is less than 10 steady amps, and probably closer to 5.

Does the furnace fan use a lot of electricity?

Typical inefficient furnace fans used in homes today consume about 1,000 kWh of electricity per year on average, or nearly 10% of an average household’s electricity use.

How much electricity do blower fans use?

A typical AC fan motor uses about 500 watts when it’s running. Therefore, if you run the fan continuously for a 30-day month (720 hours), you would use 360,000 watt hours (720 x 500) or 360 kilowatt hours (kWh). Therefore, the fan uses about 360 kWh per month in the ON mode.

Does running the fan on my furnace use a lot of electricity?

Most fans are quite energy efficient, especially in newer systems. The fan itself runs about as much energy as a refrigerator would. This can still add up to $50 a month, or $600 a year. This cost can be even higher if you consider the AC unit working harder to counteract the effects the fan may have.

How many watts does a blower motor use?

A standard fan motor uses 400 watt per hour while a variable-speed motor uses 75 watt per hour. The most direct way to save electricity is by using the variable-speed units, but there are other ways to save energy as well.

Will a gas furnace work without electricity?

A gas furnace uses the burning of natural gas to create the heat that then goes through the ventilation system. It’s like an old-fashioned stove this way: no need for electric power, just plain old heat from consuming another power source. If your gas furnace doesn’t have electrical power, it won’t run.

How many amps does a fireplace blower use?

http://www.electricmotorwarehouse.com/fireplace.htm says a replacement blower for the Regency 2400 uses 0.92 amps. To convert that to watts, simply 0.92 amps * 120v house electricity) = around 110 watts. So, your blowers or a 110 watt light bulb draw the same electricity.

How many amps does an electric furnace use?

The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; however, typically electric furnaces require a draw between 60 and 80 amps. By multiplying the volts by amps you will receive total wattage.

Does a furnace run on 110 or 220?

The 24 volt power is used in the furnace control system which includes the thermostat, and fan timer. The exception is when a “furnace” uses electric heating elements to provide heat. These can oftentimes be 220 volt systems. They also typically have a transformer that provides 24volt control power.

What size breaker does a furnace need?

Typically, an electric furnace uses 80 to 100-amp circuit breakers. However, the size breaker for furnace may vary depending on the output voltage rating and its rated power consumption. You also need to consider the 80 percent rule of thumb in your circuit breaker, since it will be used continuously.

How many amps does a 20 kW furnace use?

The most common setup for a 20 kW furnace is a 240-volt supply. This would require about 84 amps, and to meet that load requirement, you would need a 3 AWG copper wire (#3 wire or #3 AWG wire).

Can I run my RV furnace on 15 amp?

It’s safe to run your RV furnace on 15 amps. An RV can be safely powered by either 120 volt A/C current found at home outlets or 240 volts which is typical for RVs, including those with onboard generators.

Why does my furnace have two breakers?

But, why does my furnace have two breakers? Circuit breakers are added as a safety feature, not just for switching on and off your furnace. If you notice that your electric furnace has two breakers, you should know it’s not a labeling or circuit error. It’s designed that way due to power consumption and safety.
